Ligation of patent ductus arteriosus in premature neonates: anesthetic management.
A retrospective study covering a five-year period was conducted on 40 premature neonates who had had general anesthesia for surgical correction of patent ductus arteriosus. The anesthetic management of these patients was carefully reviewed. The mean weight at surgery was 1,243 gm, and the mean gestational age at birth was 29.5 weeks. ⋯ Two patients had massive blood loss intraoperatively. There were 12 postoperative deaths in the series, and 12 patients had serious long-term disability, many were combinations of hearing, visual, and psychomotor disturbances. Advances in neonatology, surgery, and anesthesiology have improved the outlook of these seriously ill patients.

Comparative StudyThoracic epidural vs balanced anesthesia in morbid obesity: an intraoperative and postoperative hemodynamic study.
Thirty-eight morbidity obese patients undergoing gastric bypass were divided into two groups. All patients received general endotracheal anesthesia with muscle relaxation and controlled respiration with N2O-O2 mixture. In addition, group I, 17 patients, received balanced anesthesia, while the remaining 21 patients, group II, received thoracic (T-5) epidural analgesia. ⋯ Postoperatively epidural analgesia was associated with a decrease in left ventricular stroke work 12%), systolic pressure-heart rate product (10%), arteriovenous oxygen content differences (17%), and oxygen consumption (20%), compared with values observed when patients experienced pain. Morphine given for relief of postoperative pain was not associated with significant changes in cardiovascular function. Continuous epidural analgesia used postoperatively for relief of pain in morbidity obese patients, following upper abdominal surgery, slightly decreases oxygen requirement and benefits cardiovascular function as reflected by a decrease in left ventricular stroke work.
