[Epidural anesthesia for coronary revascularization in the conscious patient].
Thoracic epidural anesthesia has been widely used to complement general anesthesia in coronary artery bypass grafting. The main advantages of the combination are excellent pain control and a less pronounced stress response to surgery. The invasiveness of surgery to treat ischemic heart disease has been attenuated thanks to the use of the mini-sternotomy and coronary anastomosis without extracorporeal circulation. In 4 patients, coronary artery revascularization was carried out via a mini-sternotomy, grafting the anterior descending artery to the left internal thoracic artery under high thoracic epidural anesthesia (block of segments T1-T8) with a perfusion of 0.75% ropivacaine and fentanyl in a conscious patient. There were no hemodynamic or respiratory complications during surgery. The mean duration of stay in the intensive care unit was less than 18 hours and the mean hospital stay was less than 5 days. Postoperative coronary arteriograms demonstrated the patency of all grafts and all patients were asymptomatic at 1 month. Our initial experience suggests that the use of only high thoracic epidural anesthesia is feasible in coronary revascularization in selected, cooperative patients who require a single coronary bypass graft.
