Though German hospitals are normally not built for day case surgery, this became a new challenge based on changed legal regulations. A stepwise adaptation of the present facilities to the altered necessities seems to be a relatively simple way to realise day case surgery also in hospitals. Preoperatively surgeons and anaesthetists offer office hours during the same time to avoid patients having to wait. ⋯ At a fixed time in the afternoon patients are visited by the surgeon and the anaesthetist to clear the conditions for dismission. While anaesthesia, surgery and recovery take the same time as for inpatients, the pre- and postoperative procedures are more time consuming. With a rising number of outpatients a separate department for outpatient surgery with its own administration, operating theaters and day case ward should be developed.

[Lack of sensitivity to per-anesthetic malignant hyperthermia in 32 patients who developed neuroleptic malignant syndrome].
The aim of this study was to verify whether a relationship exists between neuroleptic malignant syndrome (NMS) and anaesthetic-induced malignant hyperthermia (MH) or not. The in vitro halothane-caffeine tests were performed on muscle tissue obtained from 32 patients with documented NMS episodes. The diagnosis of NMS relied on Levenson's criteria. ⋯ Three patients were classified as MH equivocal. These findings demonstrate the lack of any link between NMS and MH. Therefore, patients with a history of NMS are not likely to be at risk of developing MH and special measures against MH are not required for anaesthesia in these patients.

[Possibilities and limits of pulse oximetry for monitoring anesthesia in horses].
In this paper the measurement technique pulse oximetry is examined in 25 halothane-anaesthetized horses. Furthermore measures are presented which lead to a successful sensor placement at the tongue of the horse. ⋯ Pulse oximetry is an important progress in equine patient monitoring. A decline of oxygen saturation in the blood is detected immediately and the registration of the pulse amplitude renders a rough estimation of the quality of peripheral perfusion.

Randomized Controlled Trial Multicenter Study Clinical Trial
A single i.v. dose of ondansetron 8 mg prior to induction of anaesthesia reduces postoperative nausea and vomiting in gynaecological patients.
The effect of a single intravenous dose of ondansetron in preventing postoperative nausea and emesis (retching and vomiting) (PONV) was investigated in a randomized, double-blind, placebo-controlled, multicentre, international study. Women of ASA class I-III, requiring gynaecological laparotomy, vaginal hysterectomy, or major vaginal surgery were selected for study. Two hundred and thirty-five received placebo, 231 received 1 mg ondansetron, 228 received 8 mg ondansetron and 229 received 16 mg ondansetron, as an infusion over five minutes before the induction of anaesthesia. ⋯ Postoperative analgesia was achieved with morphine, and prochlorperazine or metoclopramide were given if a rescue antiemetic was required. A greater percentage of patients in the 8 mg and 16 mg ondansetron groups experienced no postoperative emesis (44% and 39% respectively) than in the placebo and 1 mg ondansetron groups (29% and 28% respectively) for the first 24 hr postoperative period (8 mg vs placebo and 1 mg: P < or = 0.001; 16 mg vs placebo: P < 0.05; 16 mg vs 1 mg: P < 0.05). Similarly, the percentage of patients who did not experience postoperative nausea were 20%, 26%, 31% and 28% for the placebo, 1 mg, 8 mg and 16 mg ondansetron treatment groups, respectively (8 mg and 16 mg vs placebo P < 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
