目的:分析颅内肿瘤患者术后并发肺部感染可能的影响因素，为拟定合理防治方案提供参考。方法:抽取2018年6月至2019年10月于河南省人民医院接受手术治疗的82例颅内肿瘤患者为研究对象，依据术后有无并发肺部感染分为发生组和未发生组。设计一般情况调查表调查并记录患者基线资料，纳入全部可能的因素，经单因素与多因素分析找出颅内肿瘤患者术后并发肺部感染的影响因素。结果:82例颅内肿瘤患者中15例并发肺部感染，发生率为18.29%。发生组肺部慢性病史、侵入性操作占比高于未发生组，每日吸痰次数多于未发生组，气管切开时间长于未发生组，格拉斯哥昏迷评分量表(GCS)评分低于未发生组(n P1，n P<0.05)。n 结论:颅内肿瘤患者肺部慢性病病史、侵入性操作、吸痰次数多、气管切开时间长、GCS评分低均会增加术后并发肺部感染风险，临床应重视有上述肺部感染风险因素的颅内肿瘤患者手术方案的合理调整，并尽早为患者展开针对性干预。“,”Objective:To analyze the possible influencing factors of postoperative pulmonary infection in patients with intracranial tumor, so as to provide reference for formulating reasonable prevention and treatment plan.Methods:A total of 82 patients with intracranial tumors who received surgical treatment in Henan Provincial People’s Hospital from June 2018 to October 2019 were selected as the research subjects. And they were divided into the occurrence group and the non occurrence group according to whether postoperative pulmonary infection occurred. A general questionnaire was designed to investigate and record the baseline data of patients. All possible factors were taken into account, and the influencing factors of postoperative pulmonary infection in patients with intracranial tumor were found out by univariate and multivariate analysis.Results:Among the 82 patients with intracranial tumor, 15 patients were complicated by pulmonary infection, and the incidence was 18.29%. The proportions of chronic history of lung and invasive operation in the occurrence group were higher than those in the non occurrence group (n P<0.05). Compared with the non occurrence group, the occurrence group had more sputum aspiration times per day, long tracheotomy time and lower Glasgow Coma Scale (GCS) score (n P1,n P<0.05).n Conclusions:Chronic pulmonary history, invasive operation, frequent suction, longer tracheotomy time, and lower GCS score in patients with intracranial tumor will increase the risk of postoperative pulmonary infection. Clinicians should promptly optimize and adjust surgical procedures for intracranial tumor patients with the above risk factors of pulmonary infection, and carry out targeted intervention for patients as soon as possible.
