Anesthesiologist Questions Fever

Is my fever a side effect of anesthesia?

I have a procedure done yesterday where I was given anesthesia. Since then, I have had a low grade fever. Is this connected to the anesthesia?

Not likely
Low-grade fever after any surgical procedure is common, however, if it’s high or prolonged, consult your doctor.
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.
Infection from surgery is the most likely cause of postoperative fever.
Fever is a non specific symptom. People can get post - op fever some times. Watch for worsening of the fever and persistence of the fever. Usually post-op fever subsides in a day or over night. If this does not happen contact your surgical team
Depends on the surgery and anesthesia type. It may just be related to atelectasis if the lungs which should clear soon
A fever could be a sign of an infection, if you don't have any specific area of symptoms, such as your throat being sore, you should have your throat ears, lungs and urinary tract checked in that they are common sources of infection.
However, there is a specific uncommon reaction from certain types of anesthetics, this condition is usually hereditary and can be lethal. It is called Malignant Hyperthermia. It is a condition that is triggered by usually Succinylcholine (Paralytic agent) and/or volatile anesthetics such as the gases.
It may be due to atelectasis which is micro collapsing of the lung tissue which can cause a low-grade fever. incentive spirometry Is treatment of choice perfect
Yes, sometimes that can be the case. It should, however, dissipate in a day or two.

Fevers that occur within 24 hours after surgery are almost always due to collapsing of small airways inside the lungs. This is called atelectasis. It can be due to a combination of factors such as positioning during surgery, preexisting lung disease, or even pain after surgery preventing a deep breathing. This issue usually is temporary. There can be other causes, but patients at risk for other causes are watched closely.
A low-grade fever is common after anesthesia, and is likely related to atelectasis, or closure of the small airways (alveoli) in the lungs. Typically, if you work on deep breathing and coughing, it can help resolve this.
Low grade fever after surgery and anesthesia is not that uncommon and can be due to what is called atelectasis in the lungs. Should resolve in a day or two if you are up and about and do some deep breathing and coughing exercises. Report to your doctor if it persists or other symptoms occur.
