A prospective evaluation of 213 consecutive infrainguinal bypass procedures was performed to determine the effect of anesthesia technique on the postoperative complication rate. Limb salvage was the indication for surgery in 92% of cases. No significant differences were observed in age, sex, indication for surgery, presence of cardiovascular and pulmonary risk factors, American Society of Anesthesiologists classification, or Goldman scores between patients receiving epidural anesthesia and those receiving general endotracheal anesthesia. ⋯ Regional and general anesthesia therefore produce equivalent cardiovascular risk for infrainguinal arterial reconstruction. These results suggest that indicated operations should not be postponed or avoided for patients either requiring or requesting general anesthesia. Furthermore, other investigations of cardiac risk in vascular surgery do not require a uniform anesthetic technique for valid interpretation of results.

A retrospective review was undertaken of a random sample (N = 73) comprising 50% of carotid endarterectomies performed during 1986 to evaluate the necessity of routine postoperative intensive care unit (ICU) admission after carotid endarterectomy. Severity of illness was determined with use of the Acute Physiology Score of the APACHE II system. The Therapeutic Index Scoring System was used to quantify postoperative services used. ⋯ This represents 12.5% of the hospital charges for carotid endarterectomy. The ICU is an expensive and highly used hospital resource. Only a few patients need unique ICU services after carotid endarterectomy, and this is usually apparent within 2 hours of surgery.(ABSTRACT TRUNCATED AT 250 WORDS)
