Comparative Study[Results of various anesthesia procedures in cesarean section].
Between 1979 and 1985, 1170 anaesthetics have been used for caesarean sections. The frequency of caesarean sections ranged from 11.9% to 14%. Since 1979, the use of general anaesthesia for caesarean sections has continually decreased from 76% to 11% in favour of regional anaesthesia, and the decrease in general anaesthesia has been most obvious since 1981. ⋯ Regarding general anaesthesia, the most frequent secondary effects were said to be tachycardia, hypotension and ventricular extrasystoles. Serious complications rarely occurred; nevertheless, when they occurred, they were a threat to life under certain circumstances. Regarding regional anaesthesia, the most frequent secondary effects proved to be vomiting, hypotension and tachycardia.(ABSTRACT TRUNCATED AT 250 WORDS)

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of wakefulness with two anaesthetic regimens. Total i.v. v. balanced anaesthesia.
Fifty-five patients were assigned randomly to receive either a total i.v. anaesthetic based on a two-stage infusion of etomidate plus increments of fentanyl or a regimen based on inhaled nitrous oxide with i.v. fentanyl increments. Using the isolated forearm technique, 44% of the nitrous oxide group were found to be wakeful at some time during surgery, whereas only 7% of the etomidate group were wakeful. There was one case of awareness in the nitrous oxide group.

Two alternative anesthetic techniques for use during carotid endarterectomy were studied in a series of 424 procedures. A total of 248 were performed in patients under general anesthesia and 176 patients received regional block anesthesia. Perioperative instability of blood pressure was noted in 108 patients. ⋯ The 1 month operative mortality for the entire carotid series was 1.2% (5/424). There were three stroke-related deaths. In addition, two nonfatal major strokes and two minor strokes occurred in patients who received general anesthesia vs one nonfatal major stroke in a patient who received regional block anesthesia.
