上消化道内镜检查的死亡率为1～6/20000,严重并发症发病率为1/1000。约1/2以上是由于心肺并发症所致,其中以心律紊乱最为常见,而缺氧被认为是其重要诱因。本文旨在研究上消化道内镜检查时及检查后给氧的作用。 103例60岁以上的病人,随机分成两组,一组(50人)在内镜检查时吸氧,另一组(53人)吸空气。在检查时,通过鼻管给予氧气或空气,流速均为2升/分,插镜前局麻及镇静程度相同。两组病人的基本条件相似,分别记录各患者检查前、检查时及检查后1小时的脉搏、
Upper gastrointestinal endoscopy mortality rate of 1 to 6 20000, the incidence of serious complications 1/1000. About 1/2 or more is due to cardiopulmonary complications, of which the most common rhythm disorders, and hypoxia is considered to be an important incentive. This article aims to study the upper gastrointestinal endoscopy and post-test the role of oxygen. 103 patients over 60 years of age were randomly divided into two groups, one group (50) during endoscopy oxygen, the other group (53) inhaled air. During examination, oxygen or air is supplied through the nasal cannula at a flow rate of 2 liters / min. The local anesthetic and sedation level are the same before insertion. The two groups of patients with similar basic conditions were recorded before the patient’s examination, examination and examination of 1 hour after the pulse,
