The usual concept for anesthesia relates primarily to the prevention of pain perception during an operation or an invasive procedure . But , this concept is out of date now.,,In general , anesthesia can be defined as a drug-induced or physical factors-induced state of reversible functional depression of part of the central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 of sensation ,especially pain perception .,,,The increasing complex nature of operations sparked the development of anesthesia . Advance in related basic science especially in research in anesthesia per se ,and the development of new agents ,adjuvants , eguipments, technigues and capacity of sustaining life had changed and broadened anesthesia into a discipline concerned with more than relief of pain . over the past 5~6 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〔anesthesia〕 2、临床麻醉学(Clinical anesthesiology) 3、麻醉与危重病医学(anesthesiology and critical care medicine) department of anesthesiology and resuscitation department of anesthesiology and critical care medicine .,,,一、麻醉学开展简史,,(The history of anesthesia ),,,1、Ancient times,,〔1〕Acupuncture analgesia >475~221 B.C.,,〔2〕华陀(141~203 )麻沸散,,〔3〕Ancient Egyptians used The combination of opium poppy and hyoscyamus,,〔4〕The Incas may be the earliest to use local anesthesia .,,2、Modern anesthesiology,,〔1〕Inhalational Anesthesia (吸入麻醉),,1844 Horace wells N2 0 (氧化亚氮),,△ 1846 William T.G.

Taking part in the preanesthelic preparation.,,(2).To render patients insensible to pain and discomfort and keep the stress response at suitable level.,,(3).To monitor the patients during operations,and to regulate or 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.,,(4).To prevent and treat anesthetic complications,,(5).To monitor and treat patients in postanesthesia care unit (PACU),,2.First aid and resuscitation(急救与复苏),,3.Critical care medicine (CCM,危重病医学),,(intensive care medicine,也称加强医学),,Its clinical position is called Intensive care unit, ICU (重症监测治疗病室或加强医疗病室),,4.Pain management and its relatcd researeh epically the mechanism of pain,,5.Research ,teaching and training,,三．如何学好麻醉学,(How to learn anesthesiology),1.To combine basic medical sciences with clinical medicine(根底与临床结合),,2.To combine theory with practice (理论与实践结合),,Anesthesiologist on paper; craftsman of anesthesia,,3.To learn, to investigate continuously; and to make progress continuously.,,四．麻醉的分类,(classifications of anesthesia),1.classification of anesthetic technigues,,(按麻醉方法分类),,In a broad sense all types of anesthesia may be classified as either regional or general. But, in China, because of the wide usage and characteristic theoritical basis of epidural and spinal anesthesia, they are put into an independent class called “intravertebral anesthesia〞.,,Anesthetic technigue may be classified as follows:,General,,anesthesia(全身麻醉),,.inhalational anesthesia (吸入麻醉),,.intravenous anesthesia (静脉麻醉),,.intramuscular anesthesia (肌肉麻醉),,.rectal anesthesia (直肠麻醉),,,,,,Lntravertebral anesthesia (椎管内麻醉),,.subarachnoid block (蛛网膜下隙阻滞),,(spinal anesthesia,脊麻.腰麻),,epidural block (硬脊膜外隙阻滞),,Some times subarachnoid block and epidural block are,,also called “neuraxial anesthesia〞(神经轴麻醉),,Local anesthesia (局部麻醉),,·topical anesthesia (外表麻醉),,·local infiltration (局部浸润麻醉),,·field block ［区域〔术野〕阻滞］,,(peripheral) nerve blocks (周围神经阻滞,神经阻滞),,intravenous regional anesthesia (静脉局部麻醉),,In some textbooks and monographs, nerve blocks, spinal,,anesthesia and epidural anesthesia are collectively called,,“regional blook〞 or “regional anesthesia〞,,Everyday expressions or terms in common use;,balanced anesthesia (复合麻醉),,combined anesthesia (联合麻醉),,basal narcosis (根底麻醉〕,,endotracheal anesthesia (气管内麻醉),,endotracheal intubation (气管内麻醉),,endoBronchial anesthesia (支气管内麻醉),,2.1 classifications according to the subspecialty of clinical anesthesiology (接临床麻醉亚学科分类) such as:.,,anesthesia for cardiac surgery (心脏手术麻醉),,anesthesia for Vascular surgery (血管外科手术麻醉),,anesthesia for thoracic surgery (胸科手术麻醉),,neurosurgical anesthesia (颅脑外科麻醉),,anesthesia for organ transplantation,,(器官移植手术麻醉),,anesthesia for endocrine surgery(内分泌外科麻醉),,obstetric anesthesia (产科麻醉),,pediatric anesthesia (小儿麻醉),,geriatric anesthesia (老年人麻醉),,anesthesia for orthopedic surgery (骨科麻醉),,anesthesia for abdominal sugery (,腹部外科麻醉,),,anesthesia for trauma (,创伤外科麻醉,),,and so on,,,2.2 classifcalions according to the subspecialty of anesthesiology (,按麻醉学的亚学科分类,),,clinical anesthesiology,,critical care medicine,,pain management,,。
