Abstract
The long-acting local anesthetic, bupivacaine, was used in a series of 467 anorectal patients, both inpatients and outpatients. Bupivacaine was found to be safe and effective. Like other local anesthetics, it has none of the operative and postoperative complications frequently associated with general or spinal anesthetics. Its longer duration of action makes it extremely useful in anorectal operations on hospatilized and non-hospitalized patients. The potential hypertensive effects of using epinephrine in the local anesthetic solution appears to be negated by the calming, hypotensive effects of the intravenously administered sedatives in hospitalized patients.
