外科危重病机械通气的时机指征探讨

Indications of Mechanical Ventilation for Critical Surgical Patients

目的：探讨外科危重病机械通气的应用时机指征。方法：对２７例患者机械通气的原因进行临床分析。结果：机械通气２７例，治愈１５例，死亡１２例，死亡患者均伴有较严重的合并症或临终期。结论：术后肺功能改变是引起肺部并发症的主要原因，术前有呼吸道疾病以及创伤、休克、胸部及颅脑外伤、严重感染等，急诊手术应视为已有呼吸功能不全，对这类高危患者应加强预防性通气治疗，方能降低呼吸系统并发症。

Objective: To probe into the indications of mechanical ventilation for critical surgical patients. Method: Clinical analysis of the pathogenesis in mechanical ventilation in 27 cases. Result: 15 patients were saved,among which 5 were given precautionary mechanical ventilation,12 died with serious complications or crisis. Conclusion: The main cause of complication is the change in pulmonary function after operation. Patients with respiratory diseases,trauma,shock,chest and cranium injuries,and serious infections should be considered as having suffered from respiratory dysfunction. Therapy of precautionary mechanical ventilation should be intensified for these patients to reduce complications in respiratory system.
