There are two excellent options by which the operation can be performed:
One is local anesthesia with sedation, during which time the anesthesiologist uses intravenous medication to calm the patient. Then local anesthetic is injected into the operative site. The local anesthetic does burn initially, but it becomes effective within several seconds and then the operation can be proceed. The advantage of local anesthesia with sedation is that the patient feels no nausea or other side effects. After surgery the patient can leave the surgery center almost immediately. The local anesthetic blocks any pain for about eight hours.
Two is general anesthesia. General anesthesia involves going to sleep. The anesthesiologist gives medicine through the IV and then a tube is put in the airway to support breathing during the operation. Local anesthetic is still injected into the operative site to control postoperative pain. General anesthesia is best for patients who are very anxious and do not want to be aware of anything. There may be some feeling of being drugged after the operation.
Both general anesthesia and local and local anesthesia with sedation are very effective; both choices are good. For a redo operation general anesthesia is probably the best.
