Abstract
Anesthetic management of one hundred and twenty seven cases of aortic aneurysm resection in the past ten years (ten-year-series), and thirty one cases of those in the last one year (new series) were surveyed. We obtained some informations from the ten-year-series, and imoproved the anesthetic management in the new series accordingly. The differences are as follows: 1. All patients were induced with diazepam, fentanyl or morphine and pancuronium after premedecation with diazepam and meperidine. 2. Endotracheal tube with bronchial blocker was used to obtain a better and quieter surgical field. 3. Epidural catheter was inserted in the cases of abdominal aneurysm to obtain postoperative analgesia and to control hypertension postoperatively. 4. Lidocaine and nitroglycerin were administered intravenously during the induction of anesthesia and the latter was used continuously through the operation to control blood pressure. 5. Many patients with thoracic aneurysm were anesthetized wiht high dose fentanyl to obtain cardiovascular stability and to facilitate postoperative ventilatory support. Consequently, we achieved lower mortality and better anesthetic management.
