一、前言所谓控制性低血压麻醉,即在麻醉期间人为的使血压降低来减少术中的出血量,以利于操作进行。这种近代麻醉方法,仅有10余年的历史。1946年 Card-ner 氏曾用动脉切开放血法来降低血压,由于该法使患者处于出血性休克状态,能减低出血的耐受力,即使极少量的出血,亦常导致不可回逆的低血压,且又有引起缺氧,组织损伤的危险,操作繁杂,需有特殊装置,故未能推广。1948年英国 Gillies 氏报告用全脊
First, the introduction of the so-called controlled hypotension anesthesia, that is, artificially reduce blood pressure during the anesthesia to reduce intraoperative blood loss, in order to facilitate the operation. This modern method of anesthesia only has a history of more than 10 years. In 1946, Card-ner used arterial open blood to reduce blood pressure. Because this method puts the patient in a hemorrhagic shock state, it can reduce the bleeding tolerance. Even a very small amount of bleeding often leads to irreversible low. Blood pressure, and the risk of causing hypoxia, tissue damage, complicated operations, the need for special devices, it can not be promoted. 1948 British Gillies reports full ridge
