Review Comparative Study
A comparison of general anesthesia and regional anesthesia as a risk factor for deep vein thrombosis following hip surgery: a critical review.
We evaluated the evidence in support of the suggestion that the risk of deep vein thrombosis after hip surgery is lower with regional than with general anesthesia. A literature search was performed to retrieve all articles which reported on the incidence of postoperative thrombosis in both fractured and elective hip surgery. Articles were included if the method of anesthesia used was reported and if they used mandatory venography. ⋯ All studies showed a statistically significantly lower incidence of postoperative deep vein thrombosis with regional anesthesia (relative risk reductions of 46-55%). There were no direct comparative studies in patients who received prophylaxis. However, between study comparisons did not show even a trend towards to lower incidence of postoperative thrombosis with regional anesthesia.

Review Comparative Study[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. ⋯ 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.

Review[Conscious and unconscious awareness during anesthesia--how deep is the patient's sleep?].
A review is given over the aspects of awareness during general anaesthesia. Traditional clinical signs for evaluating depth of anaesthesia can be supplemented by objective methods such as EEG, cerebral function monitor and sensory evoked potentials. ⋯ Awareness can be graded from the obvious form, with recall of intraoperative events, to an unconscious form where the memory can be activated through special psychological techniques. We discuss the possibility of using unconscious perception of auditory signals for positive instructions to patients under anaesthesia.
