医院内获得性肺炎,是重症监护病房(ICU)所面临的重要问题,机械通气患者,院内获得性肺炎发生率高达9%~68%,病死率为不伴呼吸机相关性肺炎的3倍。分析我院重症监护病房内行机械通气48小时至8天的患者127例,分两组行多项指标检测,旨在比较气囊上滞留物与呼吸机相关性肺炎的关系。1 资料及方法1．1 一般资料选择我院ICU科因各种原因行机械通气48小时到8天的127例患者,随机分为两组。男性71例,女性56例,年龄13~76岁。外科术后106例,非手术患者21例,两组患者气管插管时间、APACHE-Ⅱ评分,留置胃管时间及胃酸抑制等一般情况相似,观察以上患者肺炎发生情况,气囊上滞留物培养及下呼吸道细菌培养结果。
Hospital-acquired pneumonia is an important issue in intensive care units (ICUs). In patients with mechanical ventilation, the incidence of nosocomial pneumonia is as high as 9% to 68% and the mortality rate is 3 times higher than that without ventilator-associated pneumonia. Analysis of our hospital ICU intracranial mechanical ventilation 48 hours to 8 days in 127 patients, divided into two groups to conduct multiple indicators test to compare the retention of airbags and ventilator-associated pneumonia. 1 Materials and Methods 1.1 General Information Select our hospital ICU Section for various reasons, mechanical ventilation 48 hours to 8 days of 127 patients were randomly divided into two groups. 71 males and 56 females, aged 13 to 76 years old. There were 106 patients in surgical group and 21 in non-surgical group. The tracheal intubation time, APACHE-Ⅱ score, indwelling gastric tube time and gastric acid suppression were similar in both groups. The incidence of pneumonia, Lower respiratory tract bacterial culture results.
