title: Anesthesia update: agents, definitions, and strategies.
abstract: The trend in modern anesthesia is to "lighten up." This generally involves use of several drugs with selective and complementary actions. The pharmacokinetic properties of such drugs should allow rapid onset, rapid recovery, and rapid responses to changes in delivered doses. Peri-operative management issues also are inherent to use of modern drugs and techniques. For example, provisions must be in place for postoperative analgesia if rapid recovery is anticipated. Light anesthesia reduces morbidity and mortality, and reduces the drug, facility, and personnel costs associated with anesthesia. However, the requirements for anesthesia and the expertise of personnel administering anesthesia vary considerably. Many regulatory bodies and scientific journals require a description of how anesthesia adequacy and depth will be assessed, as well as extensive justification for the use of neuromuscular blocking agents. In environments where adequate experience and sophistication for the use of cutting edge drugs and methods are not available, older drugs and techniques may be adequate and preferable to protect animals from pain or distress.
