Continuous epidural analgesia in the heparinized vascular surgical patient: a retrospective review of 912 patients.
Nine hundred twelve patients received continuous epidural analgesia administered through an indwelling plastic catheter while undergoing vascular reconstruction of a lower extremity. During a portion of the operative event, the patients were totally, transiently anticoagulated with heparin. None of the patients had an untoward neurologic event that could be attributed to an epidural hematoma. Our results and those of others show that this form of regional analgesia is safe and far outweighs theoretic contraindications when anticoagulation with heparin is planned as a part of the operative event. In the patients with impaired pulmonary ventilation or a cardiac disorder, this method of analgesia offers many advantages over a general anesthetic, such as obviating aspiration pneumonitis and averting prolonged support in the recovery period after completion of the surgical procedure. The regional vasodilation ensuing from the epidural blockade is an additional advantage in patients undergoing vascular reconstruction for lower extremity ischemia.
