  • Is general anesthesia safe for 9 year old child?

    Since I don't know what surgery or the reasons or his medical history, I cannot answer as completely as possible. However, yes general anesthetic is safe, but not completely without risks. But given his age and whatever surgery he is having, most anesthesiologists will schedule a time with you to meet with you and discuss the risks and the plan for anesthesia they plan on using. This gives you the chance to all the questions you want and make sure you have the best information. If this has not been offered to you, please contact your surgeon or the facility where the surgery is going to be done and ask for a pre-surgery conference with the anesthesia team. Thanks. READ MORE

  • What anesthetic is used for root canal?

    Typically, a local anesthetic is utilized and that is sufficient.

  • Is spinal anesthesia dangerous for kids?

    To answer your question in more detail, I would need to know what surgery is being done laparoscopically and to what part of the spine, age, and general medical status of your son to have a better idea about why spinal anesthesia. In general, spinal is called regional anesthesia because we can block pain to a region of the spine. Epidural anesthesia is a common way to provide anesthesia (similar to that done in some pregnancy) and spinal anesthesia which is placed in a different space and can cover a broader region of nerves. Most anesthesia provided by "spinal" technique is done with fluoroscopic (X-ray or CT) assistance to place the needle to ensure its proper placement. Typically, a catheter is then inserted through the needle and numbing medication provided after that. We often use IV sedation as well depending on the length and type of procedure. It is a safe alternative to general anesthesia. I am sure you may have already had a discussion with the anesthesiologist as to why spinal anesthesia is being recommended and they also can address any further concerns you may have regarding any risks. READ MORE

  • Do they put you to sleep for laparoscopic surgery?

    Yes if there is no contraindications to general anesthesia typically you will undergo general anesthesia please make sure you speak to your surgeon and arrange to speak to the anesthesia team as well so your questions are all answered prior to your procedure Marc A Morales MD READ MORE

  • Is it dangerous to have anesthesia with sleep apnea?

    Generally, no. Once your doctors clear you for surgery, the anesthesiologist will ask you questions about your sleep apnea as well. Generally, if the surgery requires general anesthesia, you will have a breathing tube or endotracheal tube to assist your breathing, and after removal of the breathing tube, we support your airway and breathing as needed. The effects of anesthesia are short lived, so you should be just fine. They will use CPAP if needed in the hospital for you. Marc A. Morales, MD READ MORE

  • Can I eat before twilight anesthesia?

    For “twilight anesthesia,“ typically not, but since I don’t know the procedure or what medications are involved, it’s best to talk to your physicians and obtain their recommendation. Marc A. Morales, MD READ MORE

  • How quickly does palliative anesthesia work?

    A great question what the Hospice treatment team is addressing is palliative care which may involve besides great medical and nursing care includes typically use of sedative and often pain medication and other medications that will make the patient experience less pain, less anxiety, less shortness of breath and allow for a better quality of life and time as they begin their transition. I am sorry for your family and your father but glad you are comfortable working with a medical team that will allow us to help your father to be as comfortable as possible. Depending on the dosage and medications used the effect should take effect slowly but immediately. Marc A Morales MD READ MORE

  • Will I be put to sleep for carotid surgery?

    Yes most likely will use general anesthesia check with your surgeon who can arrange for you to meet with and discuss any anesthetic issues with you. Marc A Morales MD READ MORE

  • Can anesthesia have long term effects?

    We would rarely expect to see any long term effects from anesthesia most of the medications and anesthetic agents are typically wearing off while in the recovery room. Some people experience some nausea and are tired for several hours after the procedure. If you have any further questions please feel free to discuss them with your anesthesiologist. Marc A Morales MD READ MORE

  • How long will I be under general anesthesia?

    There are no stupid questions, so having established that your question is valid, the job of the anesthesiologist is at all times to make sure that the anesthesia we are providing is at the proper amount and level that so that you would not awaken from the anesthetic prior to completion of the surgery. I encourage you as part of your pre-operative visit with your anesthesiologist to share your concern. Again, let me stress that are job as your anesthesiologist is to make the experience you have while under our care be safe. We strive to alleviate your fears, and anxieties about having surgery, and an anesthetic as much as possible. I find this works best to be allow patients to ask questions, voice their concerns, and allow us to discuss them, and to discuss the plan the anesthesiologist will have for you. This exchange of information and knowledge that your anesthesiologist will pay attention to every detail surrounding your care while under the anesthetic I believe will alleviate the concerns you have. I wish you the best of luck during your surgery. READ MORE

  • Is a CT scan done under anesthesia?

    Typically no a CT does not need to be done under anesthesia however sedation can be utilized if necessary to alleviate anxiety and to prevent him from moving too much.

  • Do I need anesthesia for my laser eye surgery?

    Typically not if a corrective eye surgery such as LASIK this can be done with local anesthesia and mild sedation taken prior to surgery. There are other more complicated laser surgeries that usually involve the retina that while still can be done with local anesthesia many are done in facilities where anesthesia is available for standby or they use Monitored Assisted Anesthesia Care )MAC) Marc A Morales MD READ MORE

  • How long does it take for general anesthesia to wear off?

    This will depend on your general health, and the type of anesthetics utilized. Most of the anesthetic is already "worn off" by the time you are in the recovery room. Most of the side effects patients experience such as nausea, sleepiness, etc are due to the pain medication and or other sedatives which may be given in conjunction with or after the anesthesia. Many back surgeries are now same day surgeries, and if in good health, and the usual type of anesthetics are given for this procedure, the effects should be gone within 6-12 hours post your surgery. The effects of the pain medication or other medications may persist while you are on them. READ MORE

  • How can I prepare my child for anesthesia?

    Usually the surgeon will coordinate with the anesthesiologist to have a pre-surgical meeting where they will go over your child's medical history and perform a brief examination. At this point they will also answer any questions you have, or your child may have concerning the anesthesia, its side effects, and what you and the child can expect. Most kids do quite well with general anesthesia, and due to the medication utilized have little memory of the actual anesthesia itself. Most people may experience being tired post the anesthesia, feeling of cold of shivering briefly, and some experience nausea. Typically most patients do quite well. READ MORE

  • Why does anesthesia cause people to shake when coming out of it?

    Shivering to anesthesia is usually not related directly to anesthetics, but rather the IV fluids given and the cooler ambient room temperatures present in the operating room, and post-op area. The cool environment and cool IV fluids lower body temperature which is preferable surgical wise for a number of reasons. However, the natural response of the body is shivering in order to activate the muscles to increase internal body temperature. This is usually temporary and subsides when body temperature returns to normal. READ MORE

  • How long does it take for lidcaine to wear off?

    I assume this was a tooth extraction? I do not know if an upper or lower tooth was extracted. Most dentists use 1%-2% Lidocaine and typically the time to wear off is 2-6 hours. If you experience longer than 4-6 hours, you should contact your provider to ascertain what medication was used and if any follow-up appointment is needed to address the continuing effect of the anesthetic. READ MORE

  • Why is my son hyper after anesthesia?

    I am not sure how old your son is, or what anesthesia he received. I am also not aware if he had any pre-existing conditions. There are some patients, however, that when they receive anesthesia can have some opposite effects to the expected sedation. These people may experience and increase in activity rather than sedation. This in medicine is referred to as a type of adverse effect or sometimes a limited idiosyncratic reaction or basically an unexpected reaction. Some children for example when given a sedative instead of getting tired, speed up. These reactions are typically rare and time limited, and should disappear as the anesthesia or medication is metabolized and eliminated from the body. If the symptoms continue, it would be wise to have your son examined by his pediatrician and or internist and consult with the anesthesiologist to determine what, if any, of the medications used may have contributed to this. READ MORE

  • Is there a difference between local and regional anesthesia?

    Yes, there is difference between local and regional anesthesia, however, it can come confusing. Local anesthesia is typically adding anesthesia to a small area. An example may be if you had a laceration to your scalp requiring stitches, we would often use Lidocaine to numb the area with the laceration so it could be repaired with stitches. In regional anesthesia, as the word implies, we are blocking a region in the distribution of path of the nerve, so a larger area. A good example of this may be if you had medical reasons where doing general anesthesia should be avoided, and say perhaps a fractured wrist. The doctor wants to reduce the fracture and place an initial cast. We could do a regional anesthesia that would block the sensation going to the wrist/hand by blocking the nerve/branches. Thus a small amount of anesthetic can be used and kept in the area by slowing down blood flow, and the reduction of the fracture can be done painlessly without the risk or bother of general anesthesia. There are other examples, but I hope this explains the difference. READ MORE

  • Is high blood pressure bad for anesthesia?

    Generally, prior to any surgery you will meet with the anesthesiologist and/or the surgeon will get a clearance from your doctors that you are stable from medical standpoint for the surgery. All vital signs including your blood pressure are closely monitored during the surgery. Typically, you may even be allowed to take your normal blood pressure medicine prior to surgery depending when it is scheduled. Most anesthesia used causes the blood pressure to drop slightly and therefore it is carefully monitored. Fluids are usually given as well to normalize your fluid and electrolyte status. If you have any other concerns or questions prior to your surgery, please let your surgeon, internist, or anesthesiologist know. READ MORE

  • Are children given anesthesia for cavity fillings?

    Yes if she is in good health and not allergic to local anesthetic such as Lidocaine or Novocain the dentist will likely numb the gum area with local anesthetic swab then inject the anesthetic to numb the area. Most children tolerate this well but some very fearful patients depending on the office facility and personnel may use a form of mild sedation before the procedure. Talk this over with the dentist to determine what will work best in their opinion and minimize the discomfort Marc A Morales MD READ MORE

  • Are people sedated in end-of-life care?

    This is an excellent question and depends on many factors, as to the wishes of the patient, facility, family, etc. Many patients, depending on the situation, may be on pain medication which in itself has a side effect of sedation, but many may have wishes for as-needed sedation. An example may be a patient who has lung cancer and has "air hunger" or shortness of breath, which leaves them feeling anxious despite oxygen. In those cases, an IV drip of a sedative agent which can be turned up or down to keep the patient comfortable, but still interactive can be excellent. There are many strategies than can be implemented, often Hospice or Pallative care physicians may feel comfortable recommending the proper combination of medications. If in doubt, ask for an anesthesia consult in addition, as often anesthesiologists are experts at reducing pain and maintaining sedation at a proper level to allow for patient comfort, but can be easily woken. These medications often have reversal agents should there be an imbalance causing over sedation. The best advice I can give family members and patients is to meet with their family and physicians before filling out power of health care living will or advance care directives. If done with pallative or hospice doctors and staff, and including anesthesiologists if needed, the type of sedation and or pain relief can be discussed and implemented before it is needed. READ MORE

  • Are there any food restrictions after anesthesia?

    There may be food restrictions if having a type of gastrointestinal surgery or procedure, but typically not from anesthesia alone. Some anesthesia may cause nausea, therefore immediately after, ice chips, or clear liquids or jello may be best until you are sure you are able to tolerate regular food READ MORE

  • My son dislocated his shoulder. Is anesthesia needed for the repair?

    For relocation of a shoulder, typically we utilize a combination of sedation plus a pain medication intravenously to assist in reducing the shoulder. If further surgical intervention would be required to repair any tendon or ligament damage, then usually a general anesthetic is utilized with a local anesthetic often added after surgery to enhance pain relief. READ MORE

  • Do I need anesthesia to get my chipped teeth fixed?

    Generally the dentist will likely utilize local anesthesia to repair them they can block all the lower teeth on one side or the other by using a local block... upper teeth require injection locally to the individual teeth involved. Some oral surgeons utilize sedation as well but be sure to discuss that before hand and determine if they have proper personnel and equipment to monitor that if it is required. Marc A Morales MD READ MORE

    It would be unusual to have nausea a week or so from stent placement however you should review your medication list with your internist and your pharmacist to insure that no new medications have been started or that there are any possible interactions from any of the medications that you are taking. Marc A Morales MD READ MORE

  • Having a section of colon removed. What is the recovery time for this?

    With this question, there is lot I am not able to tell you exactly. Your age, general health, and other medical conditions, the length of bowel being resected, and if on steroids or other similar immuno-suppressive agents may affect recovery time. The general anesthesia time is unknown because it will start just before your procedure and end slightly after the procedure. If you have never had any problems with anesthesia before, and if you have good general health, the recovery from the anesthesia portion should be relatively quickly. Some patients experience some nausea, and sleepiness depending on the length of the procedure, agents used, etc. Hopefully this gives you some answers, prior to your operation, the surgeon and anesthesiologist typically will meet with you directly to discuss this. Please raise these questions with them. Good luck on your procedure. READ MORE

  • I'm having a nose job. Will the anesthesia affect my high blood pressure?

    It is always best to make sure your internist is aware of the surgery you are having and that there are no contraindications to having the surgery. In most cases, the anesthesia provider will meet with you briefly before the surgery to make sure as well everything is good to go. Most of the time, we ask that patients take the normal blood pressure medication prior to surgery. Most anesthetics utilized typically lower blood pressure local anesthetics may raise them slightly if they contain an additive that helps to prevent localized bleeding. However, the anesthesiologist is prepared for these things, and if you have any other concerns or questions, please feel free to ask your private physician and/or the anesthesia provider so that you won't worry.

READ MORE

  • Can anesthesia lead to nerve damage?

    I am unsure what anesthetic procedure you are speaking about. Generally, no anesthetic should cause nerve damage. Improper technique could hypothetically cause damage to a nerve if injected, but even that would be rare and usually temporary. READ MORE

  • Why do I need to meet the anesthesiologist before my surgery?

    While I am not sure what surgery you are having or other medical problems you may have if any, it is quite routine to have a meeting with the anesthesiologist. The anesthesiologist will review your general health, your past history if any with sedation, or anesthetic agents, the medications you are on if any, and general medical conditions. They usually also will perform a brief medical exam. After reviewing all the information they obtained they will review with you the general plan they have for the type of anesthetic that would be best suited for you based on the procedure planned, and your medical history. They will go over any concerns and answer any questions you may have about the anesthesia and how it will be provided, and recovery time. They will also go over any side effects, or complications that may be present, if any, for the anesthesia planned. During the visit they will address and answer any questions you have as well. This way you as the patient, and your anesthesiologist are both on the "same page", comfortable with the anesthetic plan, and have your questions or concerns answered so each of you are comfortable. I hope this answers your question READ MORE

  • Do I need to stop taking Adderall before I take anesthesia?

    Thank you for the question, Typically, Adderall is given in short or long acting preparations. If the Adderall does not affect your blood pressure or heart rate (which in some it can), or interfere with any of the planned anesthetic agents, you usually will not have to stop it, but take your last dose typically 8 hours prior to your surgery, and resume when you can tolerate oral fluids and medications. However, you should always address starting and stopping medications with your attending physician and attending anesthesiologist, as they will know what if any other factors or history they may be concerned with prior to medial branch nerve ablation (burning of the nerves). READ MORE

  • I have sleep apnea and am scheduled for an upcoming surgery. Are there any risks?

    Thank you for your question. As there are several reasons for sleep apnea this should always be discussed with your anesthesiologist. The causes of sleep apnea also may be related to other medical conditions which may play a role in anesthetic selection. Since this is a knee surgery and typically requires general anesthesia, although the sleep apnea typically does not directly affect the anesthesia, depending on the severity of it, and if due to an uncorrected anatomical airway obstruction it is something as an anesthesiologist would want to be aware of and take precautions for if warranted. Otherwise typically the diagnosis of sleep apnea alone is not a concern. READ MORE

  • Does anesthesia cause muscle twitching?

    Typically, anesthetic agents do not cause muscle twitching, especially those in use today. You might check with your doctor who performed the test and they can advise what happened, and check what anesthetics were used. READ MORE

  • How soon after anesthesia can my sister eat?

    All anesthetic providers and surgeons are aware by time of the procedure what type of Diabetes (Type I or II) and what blood glucose levels the patient typically has. We compensate for no food typically given 8 hours prior to surgery by monitoring the glucose level, and providing sugar and insulin (to reduce sugar) if needed. Since some patients may be unable to eat due to sedation or nausea post surgery, the IV with sugar if needed, and glucose monitoring continues until the patient is able to eat on their own. READ MORE

  • Can a root canal be performed under general anesthesia?

    You can ask, however most root canals can be performed in the dental office with sedation and local anesthesia. Dental offices are unable to offer and monitor appropriately general anesthesia. This would require you to go to a surgical center of hospital which may not be covered by your insurance provider. General anesthesia while safe is not without risk and requires an anesthesia provider meet and discuss everything with you to determine if you are a candidate. In my experience most dental providers especially root canal dentists if you are forthright with them of your concern and anxiety, will provide some medication to take before your procedure and some light sedation to use during the procedure or Nitrous oxide (laughing gas) if warranted, not contra-indicated and available. READ MORE

  • Is it possible to be allergic to anesthesia?

    The vast majority of patients are not allergic to general anesthesia agents. Some patients may have allergies to local anesthetics such as Lidocaine (similar to what dentists use) but most again do not. If you have concerns your anesthesiologist can address them with you prior to the procedure or you can consult with your allergist. If you have had Lidocaine or Novocaine in the dentists office without problem before, generally you should be fine. READ MORE

  • Does local anesthesia also make one drowsy?

    Typically if just a local anesthetic such as Marcaine or Lidocaine was given you should not feel drowsy. If some reason sedation was given in addition to the local anesthetic that could account for drowsiness. READ MORE

  • Is my fever a side effect of anesthesia?

    This depends on the type of anesthesia given but typically most anesthetics will not per se cause fever on the day after a procedure. We often ask that when was has low grade fever after a procedure that they check with their surgeon to be certain. READ MORE

  • How long does anesthesia stay in the blood?

    Typically not long but to answer this correctly it would be helpful to know what anesthesia agent was utilized. For short procedures such as a CT scan most anesthesiologists will use a very short acting agent and the child therefore would not have a long effect from the sedation. READ MORE

  • What are the other types of anesthesia that is used in surgery?

    Anesthesia typically utilized in procedures may vary. Depending on the length of the procedure may anesthesiologists are moving towards TIVA (Total IV Anesthesia) which typically has less side effects than inhilation anesthesia. There is regional anesthesia where one blocks sensation in a particular region such as an arm. There is local anesthesia which is used to numb a small area such as to place sutures. Epidural anesthesia is a type of regional anesthesia where anesthetic is place into the Epidural space of the spine and is often used for labor and delivery. READ MORE

  • Is it riskier for people who are overweight to go under anesthesia?

    There are some risks associated with being overweight and some of the medical conditions which might be associated with being overweight such as hypertension, diabetes, etc. However, having a C-Section is often done with an epidural block using local anesthetics. This is a very safe procedure, and avoids a number of concerns one might have with general anesthesia. Nonetheless, you should be speak with the anesthesiologist who would be present for the C Section since it sounds as though it is elective, and present your concerns so that they can review your medical history, conduct an exam, and talk to you about your anesthetic options. READ MORE

  • Can anesthesia interact with breast milk?

    Some anesthetic agents can be excreted in breast milk, this would depend on what agents were utilized. The best way to make sure is to check with your surgeon who can find out what agents were utilized. Most agents would not stay long if excreted so likely if more than a week post your procedure and not on any other medications to prohibit breast feeding then you are likely good to go. Again, check with your surgeon and or pediatrician for final confirmation. READ MORE

  • I am planning to pierce my nose. Is there an ointment that I can apply to numb the area and ease the pain?

    Depending on the medication he gave and where injected yes it is still possible that the area will feel numb and swollen. Adding an ice pack to reduce swelling may help. If the area is not improving within another 1-2 hours you should notify the oral surgeon or dentist so that they can re-evaluate the situation. READ MORE

  • For corn removal will the doctor give me anesthesia?

    Most often these are simply a pearing down of excess skin that grows until it is flat against the normal skin. Likely no anesthesia is necessary and cold application may help with any discomfort during the procedure. Please let you physician know if you are experiencing discomfort and a local anesthetic likely can be given. READ MORE

  • Can hypertension along with anesthesia become a problem?

    Most anesthetics actually lower the blood pressure it is rare for them to elevate it except in very rare cases or conditions. Generally you would take your blood pressure medication as indicated and check with your anesthesiologist and internist for any further instructions prior to your surgery. READ MORE

  • Is local anesthesia better than general anesthesia?

    Local anesthesia is typically used for minor procedures whereas general anesthesia is used for a surgical procedure where local anesthesia would not be possible. Some surgical procedures can be done with regional anesthesia whereas local anesthesia is used to block a nerve or nerve bundle to an area. The best thing to do with fears you stated about being "knocked" out is to meet with the anesthesiologist prior to your procedure so that they understand what concerns you may have and can come up with the best plan of action for you. READ MORE

  • Can anesthesia cause drowsiness long after surgery?

    It is unclear from the question you wrote, as I am assuming your mother had cardiac bypass surgery. Yes, anesthesia, depending on the type utilized, could contribute to her being sleepy or drowsy, but there could be other problems as well, such as low blood count (anemia) if blood was lost along with other problems. If this persists, the best idea is to have your mother evaluated by her treating physician to ascertain the reason for her feeling poorly. READ MORE

  • My son was given anesthesia before his CT scan and is now drowsy. Is this normal?

    As it is unknown what he received the question is a little difficult to answer. Most of the time a mild sedative is utilized for CT scanning and the effect may take several hours to wear off. It is not uncommon to feel tired for several hours post administration of a sedative type medication or what other medications might have been given. If any questions or concerns, please contact his physician or take him to the Emergency Room for further evaluation. READ MORE

  • I have heard the anesthesia given during C-section can later cause back pain. Is it true?

    Generally, this is not true. Most often, epidural anesthesia in combination with sedation is utilized. At times, general anesthesia is required. There may be headache and/or residual back pain and some numbness after the procedure, generally these resolve in 3-5 weeks. Please check with your OB-GYN and make sure you meet with your anesthesiologist prior to your procedure to go over questions you may have. READ MORE

  • Can an overdose of anesthesia cause death?

    There are always risks to anesthesia, which is why you would undergo an exam by your private and or referring physician and you will meet with an anesthesiologist prior to your procedure to review the plan, your prior experience if any, with anesthesia, risks, benefits, etc. Overdose of anesthesia is rare ( if worried about narcotic or sedative) these are closely monitored and reversal agents are available should they be needed. The vast majority of cases go well READ MORE

  • Why do my arms feel numb after surgery?

    It is unclear but it sounds as though a regional anesthetic may have been given to allow the surgery to occur. As these block specific nerves it is possible that you would experience this in both arms. The numbness should wear off shortly after the procedure. If it does not resolve within a day or so, please contact your surgeon and anesthesiologist for further information. READ MORE

  • I am a diabetic and a blood pressure patient. Could anesthesia have any counter interactions during my surgery?

    There are risks associated with all types of anesthesia, but these are typically controlled. It is standard for your treating physician and surgeon to examine you and obtain EKG and labs and you should meet with your anesthesiologist to review their recommendations and come up with the safest plan for administration of anesthesia during your surgery. READ MORE

  • Would my diabetic medication have a counter interaction with anesthesia?

    Your OB-GYN physician and internist will provide information to your anesthesiologist about your diabetes and medications provided. They should not interfere with the anesthesia, and a plan will be developed between your doctors to ensure safe administration and monitoring of the anesthesia, blood sugar and infant. READ MORE

  • Is anesthesia in low blood pressure patients risky?

    Depending on the type of anesthetic administered, blood pressure can drop. In most cases of root canals, local anesthetic and a mild sedative may be administered. This should have little effect on your blood pressure, but prior to the procedure it is wise to advise your oral surgeon of this condition, your internist and if warranted, during the procedure have an anesthesia provider on standby, (MAC) Monitored Anesthesia Care, that would be able to constantly monitor for any reactions to your blood pressure. READ MORE

  • Can anesthesia be administered to a patient with diabetes?

    Yes, most procedures such as this can be done under local, regional or general anesthesia. The anesthesiologist will consult with the surgeon and physician providing diabetic care to develop a plan that is the safest for your husband. READ MORE

  • I need to undergo a nail removal treatment. Will anesthesia have to be administered for this?

    In most cases such as this, local/regional anesthesia with Lidocaine or Marcaine (similar to that used by dentists) can be given to provide anesthesia to the area for removal. READ MORE

  • What can I do for the back pain that has started two years after my C-section?

    Since there could be a number of issues causing back pain, an exam by a board certified orthopedic spinal specialist would be appropriate to begin with, and if warranted, they can do imaging beginning with plain X-ray to MRI to further diagnose and ultimately find the correct treatment for you. READ MORE

  • Can anesthesia have any side effects?

    Generally most patients prior to surgery are asked to be cleared medically by their internists. Once receiving a general clearance in addition the anesthesiologist will perform an evaluation and decide what type of anesthesia is best for your father. He/she should review any contraindications or side effects of anesthesia with him and look for any interactions with medications he may take. In the vast majority of cases this type of coordination helps ease any anxiety the patient and family may have with anesthetics and allow for safe administration of anesthesia. READ MORE

  • I have a uterine septum that needs to be removed. What is the safest anaesthesia for me?

    Your OB-GYN surgeon can ask for a pre-surgical consultation with anesthesia to review any medical conditions you may have and decide which type of anesthesia is best for you. TIVA (Total IV Anesthesia) is a good option, and often uterine surgery can be achieved with epidural anesthesia (local anesthetic placed in cathether inserted into the epidural space in your back) similar to that given in labor. READ MORE

  • Can natural health supplements like ashwagandha have a bad effect with anaesthesia?

    Ashwaganda can have an interference with other sedatives utilized during anesthesia. According to the manufactures guidelines they do recommend stopping the supplement two weeks prior to any surgery. To be on the safe side since it can have a sedative effect and the time period for it to clear your system is unknown, following the guidelines of 2 weeks seems prudent. READ MORE

  • I am planning to go for a lip piercing. Will anaesthesia help in easing the pain?

    I am not sure what if anything people performing lip piercing use for pain. More often than not they would likely use ice or a topical cooling agent and then do the piercing. Topical anesthetic creams over the counter or by prescription would simple help numb the outside surface of the lip not the deeper structures. I would check with the person performing the procedure or others who have had it as to the pain they perceived during the event. READ MORE

  • I am having a painful sensation around my tailbone after a blood patch was done. What could be the reason?

    It is unclear exactly where you are experiencing the pain. Typically the lumbar puncture would be down around the Lumbar 4-5 vertebrae which is close to the sacrum that some consider tail bone. A blood patch is used after cerebrospinal fluid leak. It normally takes care of headache and some back discomfort. If concerned and still having issues it is wise to ascertain a second opinion from a back specialist to exam you and if necessary perform imaging. Likely if no other symptoms if related the pain should improve. READ MORE

  • I have knee pain after wearing high heels. What to do?

    This question is best addressed by your family doctor, podiatrist or orthopedist. As an anesthesiologist, we usually don't address this. READ MORE

    You should always inform the physician and anesthesiologist if present, of any and all medications prescribed or non-prescribed that you have taken. Likely, you would not need to reschedule the test, however this would be up to the physician performing it. Marijuana or THC can affect medications used for sedation. READ MORE

  • Could I be allergic to anaesthesia?

    Vomiting is not an allergic response. Depending on the type of anesthesia used and how it is administered, this is a fairly common side effect. If you are to have anesthesia in the future, simply advise the anesthesiologist of your experience and this likely can be minimized with antiemetic or anti-nausea medication. READ MORE

    He should advise during his preoperative visit with the anesthesiologist the sleeping medication he is taking. Typically, most sleeping medications are short-acting and likely would not interfere with the procedure. READ MORE

    Typically if in good health and no contraindications, anesthesia is okay. Most root canals can be done with local anesthesia, so sedatives or other anesthesia is typically not needed.

  • Is it a must to stop Adderall while getting anaesthesia?

    During the preoperative visit with her anesthesiologist, she can discuss this. If having general anesthesia, typically this medication would be held the night before surgery.

  • Vomiting after sugery

    Depends on what type of anesthesia you are having and what medications are being used. Vomiting is seen most often with use of narcotics for pain and some inhalation anesthetics. Please bring this up on your pre-operative visit with your anesthesiologist so medications can be used to minimize the side effect such as anti-emetics (anti-nausea agents) and at times we can use acupuncture point (s) to assist such as P-6 (pericardium 6 or Nei Guan) in addition to medications. READ MORE

    Would need more information such as where the nerve root compression is occurring and what is the presumed cause of the compression. After knowing this we should be able to advise you better. Thank you READ MORE

  • Pain in the back. Is it due to epidural?

    Typically one should not have pain occurring a year post delivery from an Epidural anesthetic. Other source(s) of pain should be ruled out. A plain-x-ray of the effected area may be warranted initially. If after this nothing is found, clinical exam with an orthopedic specialist may be helpful to further determine the cause of the pain. This may include but not be limited to physical therapy, anti-inflammatory medication, if warranted clinically a MRI or CT if the cause is not found or the situation resolving with conservative therapy. READ MORE

  • What is procedural anesthesia?

    Typically the terms can be mixed up with Conscious sedation. Procedural anesthesia is a general term meaning an anesthetic agent either local, regional block or general may be used. In some cases this can be done by a non-anesthesiologist. Surgical anesthesia generally implies that the procedure being done is done in a surgical facility, or hospital and that general anesthesia by IV or IV/Inhalation anesthesia is being done. READ MORE

  • What decides the medication before my surgery?

It is not uncommon to give either oral or IV medication prior to a procedure, but again dependent upon the items previously mentioned. READ MORE

  • Should all medications be stopped before anesthesia?

    "Blood thinners" are typically anti-coagulants such as Coumadin or Xarelto or Heparin,however anti-platelet medication such as Aspirin or Plavix can get put into this category. The decision to stop medications is made with your internist, your surgeon and anesthesiologist. This will likely depend on the reasons you are on anti-coagulants, and the procedure you are having done. Checking with your physicians prior to the procedure especially with regards to anti-coagulants is important. READ MORE

  • Sickness after anesthesia?

    It depends on the medications being given. Many narcotic pain medications have a side-effect of nausea. Use of inhaled (gas) anesthesia may lead to more nausea as well. Since this is a known side effect, and if you have had problems with anesthesia or certain types of anesthetics in the past, it is the usual custom to meet with your anesthetic provider prior to administration of anesthesia to review your history and perform a physical. We often utilize Zofran (R) an anti-nausea agent or other similar type agents prior to anesthesia depending on length of the case or in recovery area to minimize this effect. READ MORE

  • Can anaesthesia lead to neurological issues?

    The onset of hand tremors and speech issues would be rare due to anesthesia alone. Some people are naturally sleepy and groggy and may have dry mouth, affecting speech. Since I do not know what procedure he had or his prior medical conditions, it is difficult to answer this question. If you can provide further information, we could perhaps answer your question better. READ MORE

  • Is laughing gas ok for someone with anxiety?

    Laughing gas is Nitrous Oxide, which is given in combination with oxygen in small amounts to reduce anxiety. It can produce a somewhat euphoric effect (happy effect) which is likely the origin behind its slang name. It should not worsen your anxiety, in fact you should feel better during and after the procedure. READ MORE

  • Can anesthesia lead to neurological issues?

    Generally, hand tremors do not come from general anesthesia, there are some medications used not commonly today that could theoretically cause some neurological issues. Without knowing the procedure or your father's prior medical history and medications used, it is difficult to answer this question. READ MORE

  • Do kids need anesthesia before being taken for a CT scan?

    This depends. Generally, the child would not be given a general anesthetic before the procedure. However, they usually want the child sedated but somewhat awake so that they cannot move, and are not frightened by the scan and the noise it can make. READ MORE

  • Is anesthesia safe for older people with dementia?

    Most dental procedures are done with IV sedation and local anesthesia or small amounts of IV anesthesia if done at a hospital. Although sedative medication could cause some brief temporary confusion provided he is otherwise in good health there is no known contradiction to use of sedative local anesthetic or IV anesthesia. Marc A Morales MD READ MORE

  • Chance of serious complication from anesthesia?

    If you are basically in good health there should be minimal risk for anesthesia. For wisdom teeth depending on how many they are planning on taking out, usually local anesthesia and sedation is enough. If they are using TIVA (Total IV Anesthesia) with an anesthesiologist present, then they will perform a history and physical exam and ask you a series of questions to determine your risk of an anesthetic. READ MORE

  • Do I have to stop taking my vitamins before anesthesia?

    Generally if you are having general anesthesia we ask that you have nothing by mouth 8-12 hours prior to your anesthesia. You may take certain medications with limited amounts of water prior to the procedure. We would generally recommend *you not take* B12, Probiotics or D Vitamins before your procedure as they are not critical medications. If you are on certain prescribed medications that you must take daily, we would recommend checking with your doctor or anesthesiologist prior to your anesthesia to see if they recommend taking that medication(s) prior to your procedure. Unless otherwise noted we recommend you avoid taking Aspirin, Motrin or Ibuprofen prior to your procedure as well. READ MORE
