[Complaints in the postoperative phase related to anesthetics].

In two prospective, randomized studies the frequency of headache, nausea, vomiting, and analgesic requirement during the first postoperative 24 h was observed in order to study differences between the sexes and the inhalation anesthetics halothane, enflurane, isoflurane, or balanced anesthesia with enflurane/alfentanil. Nausea and vomiting were more frequent after enflurane than after halothane or isoflurane. There was no significant difference between anesthetics and frequency of headache, but there were significant differences in postoperative analgesic requirements which were highest after halothane and lowest after isoflurane.

[Clinical experience with methohexital-nitrous oxide anaesthesia (author's transl)].

The effects of methohexital, given as a 0.1% intravenous drip in combination with nitrous oxide were studied in 159 persons who had various types of surgical operations. The depth of anaesthesia was easily controlled, the circulation remained unaffected and the combination was well tolerated.
