Animal anaesthesia is a wide and varied subject considering the great number of available animal models, each having its characteristic tolerance and reaction to anaesthesia and its behavioural peculiarity. It is more often than not that experimental researchers tend to give scant attention to animal anaesthesia in the preparation of a research protocol as a result of which their research findings can become difficult or impossible to interpret. This article outlines the fundamental anaesthetic requirements and techniques in various animals and the practices adopted by the Department of Experimental Surgery, Singapore General Hospital. Consideration in the choice of anaesthetic drugs in various animal models and experimental situations, and problems of animal handling before and after anaesthesia are highlighted.

[Risk assessment and patient information before anesthesia].
In order to determine the risk of anesthesia the anesthesiologist has to assess both the physical and the psychological status of the patient. The essential basis of any preoperative medical evaluation are the history and complete physical examination of the patient. Few laboratory screening tests and, in case of pathological findings, specific diagnostic procedures will ensue. ⋯ He also informs the patient about the planned anesthesia, the sequence of further measures, the risk of anesthesia, and accompanying risks. The family doctor can help to facilitate the preoperative assessment by performing certain examinations himself and by providing the anesthesiologist with relevant informations. By giving a piece of advice to the patient he can help to prepare him for anesthesia and to reduce fear and apprehensiveness.

Randomized Controlled Trial Comparative Study Clinical TrialPropofol for ambulatory gynecologic laparoscopy: does omission of nitrous oxide alter postoperative emetic sequelae and recovery?
The role of nitrous oxide in postoperative emesis is controversial. This prospective randomized study was performed to compare the emetic sequelae and quality of recovery between a group of patients anesthetized with propofol alone and a group anesthetized with propofol plus nitrous oxide. Seventy patients, ASA grade I or II, scheduled for ambulatory gynecologic laparoscopy under general anesthesia were included. ⋯ Otherwise, the recovery variables were comparable between the two groups. We conclude that supplementing propofol with nitrous oxide in patients undergoing ambulatory laparoscopy reduces the requirements of propofol, expedites immediate recovery (emergence), and does not increase the incidence of postoperative emesis. This tends to confirm that there is no clinical advantage to omitting nitrous oxide.
