目的评价机械通气（ＭＶ）治疗老年Ⅱ型呼吸衰竭的临床意义，提出治疗的适应证，讨论并发症的种类和发生率，及其防治方法。方法回顾分析１９７７年１月～１９９４年４月１８年间我科收治的３２例老年Ⅱ型呼吸衰竭患者，根据不同人工气道和呼吸机类型，评价各自的优缺点，并强调同步间歇指令呼吸（ＳＩＭＶ）和压力支持通气（ＰＳＶ）呼吸模式的应用价值。结果ＭＶ治疗老年Ⅱ型呼吸衰竭的成功率为７５％。２例存活５年以上。本组１３例采用延长的气管插管（７ｄ～２１ｄ，平均１６±２．１３ｄ）。８例长期保留气管切开套管。讨论ＭＶ救治老年Ⅱ型呼吸衰竭疗效肯定，采用ＳＩＭＶ和ＰＳＶ呼吸模式有利于撤机，延长气管插管当因人而异，对高龄及第２次切开应考虑长期带管。
Objective To evaluate the clinical significance of mechanical ventilation (MV) in the treatment of respiratory failure in elderly patients with type Ⅱ respiratory syndrome. To put forward the indications for the treatment, discuss the types and incidence of complications and their prevention and treatment. Methods A retrospective analysis was performed on 32 elderly patients with type Ⅱ respiratory failure admitted to our department from January 1977 to April 1994 in our hospital. The advantages and disadvantages of each type of artificial airway and ventilator were evaluated according to different types of artificial airway and ventilator. SIMV) and pressure support ventilation (PSV) breathing patterns. Results The success rate of MV in treating type Ⅱ respiratory failure in elderly was 75%. 2 cases survived more than 5 years. The group of 13 patients with prolonged endotracheal intubation (7d ~ 21d, an average of 16 ± 2.13d). 8 cases of long-term tracheostomy tube. Discussion MV treatment of elderly type Ⅱ respiratory failure is positive, the use of SIMV and PSV breathing mode is conducive to weaning, prolonged tracheal intubation varies from person to person, the elderly and the second incision should consider long-term with the tube.
