Anesthesia for outpatient gynecologic surgery

Anesthesia care for patients undergoing ambulatory gynecologic surgery has improved incrementally over the past few years. Emphasis has evolved beyond the safe provision of care, because this has largely been achieved. Comfort, speed, and efficiency have taken on new importance.

Many changes relate to improvements in non-narcotic analgesic techniques and use of various supralaryngeal airways, such as the ProSeal LMA. Also, use of depth of anesthesia monitors and administration of potent short-acting beta-blockers and narcotics to control hemodynamic variables are examples of new anesthesia developments well applied to ambulatory gynecologic cases. Finally, anesthesia care is changing in some instances because surgical techniques are advancing, such as hysteroscopy, and can now be done in an office with little or no anesthesia.

Local anesthetic use in gynecologic laparoscopy appears to improve postoperative pain control modestly, especially when given into the peritoneal cavity. Supralaryngeal airways, such as ProSeal LMA, appear to provide effective ventilation in laparoscopy, although their ability to protect against aspiration is unclear. The speed and comfort of emergence, recovery, and discharge may be improved by consciousness monitoring during general anesthesia and by drugs intended to modulate hemodynamics.
