[Epidural conduction anesthesia versus general anesthesia. A critical evaluation of outcome studies using as examples cesarean section and patients with hip fractures].

In the field of anaesthesiology, outcome studies are undertaken to investigate the influence of different anaesthetic techniques on the intra- and postoperative course of patients in special clinical situations. The design of these studies should follow high methodological standards. In the past, most studies were undertaken in patients during Caesarean section and in the treatment of hip fractures in the elderly. Up to now, results do not clearly indicate the use of certain techniques in concrete clinical situations. Decisions must be made in accordance with clinical aspects, individual experience and in cooperation with the patient and the surgeon.
