胃癌是常见的消化系统恶性肿瘤，目前外科手术是胃癌得到根治性治疗的主要手段。而肺部感染是胃癌术后常见的并发症，但目前肺部感染尚无明确统一的定义，目前研究显示，胃癌术后肺部感染发生率为1.8%~18.1%。术后肺部感染的发生会延长患者住院时间，增加住院费用，甚至发展成为呼吸衰竭，进而导致患者术后早期死亡。目前，研究发现影响胃癌术后肺部感染的因素有年龄、吸烟史、肺功能、肺部疾病史、手术方式、手术时长、术中出血量、胃管留置时间和术后卧床时间等，其相应的围手术期干预措施也较多。本文就胃癌术后肺部感染发生的危险因素及围手术期干预措施进行综述。“,”Gastric cancer is a common digestive system malignancy. Surgical operation is the main treatment of radical treatment for gastric cancer. Pulmonary infection is a common postoperative complication of gastric cancer. Because there is no clear and unified definition of pulmonary complications, the current researches show that the incidence of postoperative pulmonary infection of gastric cancer is about 1.8%-18.1%. The incidence of postoperative pulmonary infection will prolong the hospital stay, increase the cost of hospitalization, and even develop into respiratory failure leading to early postoperative death. There are many factors affecting postoperative pulmonary infection of gastric cancer, including age, smoking history, pulmonary function, pulmonary disease history, operation method, operation time, intraoperative bleeding volume, gastric tube retention time, postoperative lying time and so on. There are also many perioperative interventions. This article reviews the risk factors and perioperative interventions of postoperative pulmonary infection of gastric cancer.
