1、临床麻醉学（Clinical Anesthesiology）绪论（Introduction）,The term “anesthesia”( 麻醉) is derived from Greek Word, it means “lack of feeling or sensation ” or“privation of senses ” im plying lack of appreciation. The usual concept for anesthesia relates primarily to the prevention of pain perception during an op

But , this concept is out of date now.,In general , anesthesia can be defined as a drug-induced or physical factors-induced state of reversible functional depression of part of the central nervous system or peripheral nervous system,which is characterized by loss o

4、 life had changed and broadened anesthesia into a discipline concerned with more than relief of pain . over the past 56 decades ,anesthesiology(麻醉学) has emerged as a clearly defined specialty and firmly established .,The evolution of modern anesthesiology may be devided into 3 stages : 1、麻醉（anesthes

Taking part in the preanesthelic preparation. (2).To render patients insensible to pain and discomfort and

15、keep the stress responseat suitable level.,(3).To monitor the patients during operations,and to regulateor control the importaut physiological functions of the patients in order to provide maximum safety for the patients and to provide optimal operative conditions for surgeons.
