General anesthetic techniques.
General anesthesia is the most common form of anesthetic management for ambulatory surgery. Patients, in general, prefer general anesthesia because it is less anxiety provoking. During the last decade, the availability of several short-acting agents with high clearance has made general anesthetic techniques much safer and more predictable for outpatients. Besides, general anesthesia today is associated with a quick and full recovery with minimal postoperative side effects. Proper preanesthetic psychological and, when necessary, pharmacological preparation as well as proper selection of anesthetic agents are the keys to the success of general anesthetic technique for ambulatory surgery. Although both TIVA and total inhalation anesthetic techniques have their advocates, balanced anesthesia is most popular. The introduction of several new agents (e.g., propofol, desflurane, vecuronium, atracurium, mivacurium, rocuronium, alfentanil, ondansetron, ketorolac) has made ambulatory general anesthesia less challenging and more interesting. In the future, the new anesthetic sevoflurane, and the new opioid remifentanil, may prove useful for ambulatory anesthesia. The LMA has all but revolutionized airway management during general anesthesia for ambulatory surgery.
