The two most important factors are to get your husband in optimal medical condition as time permits and select a board certified anesthesiologist competent in regional anesthesia.
This is not medical advice as I have inadequate information regarding your husband. A board certified anesthesiologist can usually manage such a problem as it is not uncommon.
Additionally, I would explore the use of hyperbaric oxygen therapy both pre and post operatively to enhance healing.
May God bless.

The anesthesia can be provided safely for your spouse. Depending on other medical conditions and extent of the infection, the anesthesiologist may choose to either do a general anesthetic or with local/regional anesthetic.
