目的：探讨长期昏迷与肺部感染的关系及治疗。方法：对昏迷的程度、时间、诱发因素与肺部感染的关系及病原学、治疗预后进行临床分析。结果：肺部感染发生率与昏迷程度及持续时间成正比，肺部感染以Ｇ—杆菌为主，混合感染、二重感染多见。结论：根本原因在气道内引流不畅，治疗重在气道护理，纤支镜治疗值得推广。肺部感染多为其直接死亡原因，根本原因在于不可逆性的昏迷。
Objective: To explore the relationship between chronic coma and pulmonary infection and treatment. Methods: The degree of coma, time, the relationship between predisposing factors and pulmonary infection and etiology, prognosis of clinical analysis. Results: The incidence of pulmonary infection was proportional to the duration of coma and pulmonary infection. The majority of pulmonary infections were G-bacilli and mixed infection. Conclusion: The underlying causes of poor drainage in the airway, the treatment of airway care, bronchoscopy is worth promoting. Pulmonary infections are mostly direct causes of death, the fundamental reason is irreversible coma.
