Continuous epidural anesthesia and postoperative epidural narcotics in vascular surgery

A combination epidural technique using local anesthetics intraoperatively and morphine postoperatively is shown to offer many advantages. These benefits include inhibition of the surgical stress response, decreased cardiorespiratory depression, decreased blood loss, decreased intubation and pulmonary infection, decreased thromboembolism, decreased hyperglycemic and hypertensive response, nitrogen sparing, a stable resting metabolic rate, prevention of immunosuppression, simplification of cerebral status monitoring, and earlier ambulation and hospital discharge. The main disadvantage in patients undergoing vascular procedures is the risk of epidural hematoma. A review of the literature confirms the extreme rarity of this risk and, in view of the emerging benefits, argues for reconsideration of epidural technique in vascular patients. The addition of epidural morphine to this combined technique affords a postoperative pain-free continuum unmatched by any other method. This significantly decreased pain stress in cardiac patients increases safety and comfort. In conclusion, epidural anesthesia and postoperative epidural narcotics provide a safe and reliable method of management for patients undergoing vascular procedures.
