Background. The presence of chronic obstructive pulmonary disease (COPD) should not be considered a contraindication to operation but should rather identify those patients that require special preoperative and postoperative pulmonary care. The purpose of this paper is to report our experience in the use of combined spinal and epidural anesthesia (CSEA) for open AAA repair in such patients.
Methods. From April 1997 to November 1998, three patients with severe COPD underwent elective open infrarenal AAA repair under CSEA. All the patients satisfied one or more of the following criteria: a room air PaO2 ≤60 mmHg, PaCO2 ≥45 mmHg, FEV1 ≤50% of predicted, and/or FVC ≤75% of predicted, and one of them was on home oxygen preoperatively. Preoperative preparation of the patients consisted of breathing exercises with incentive espirometry, elimination of underlaying pulmonary infections and usage of bronchodilator therapy.
Results. All the patients tolerated surgery safely. None of them developed postoperative complications, including pneumonia and other respiratory conditions. No significant changes in room air arterial blood gas or pulmonary function was recognized before and after surgery.
Conclusions. CSE anesthesia is a viable anesthetic option for conventional AAA surgery in patients with severe COPD since it can preserve spontaneous breathing and provide additional respiratory benefits over general anesthesia.
