| 目的 调查呼吸机相关性肺炎(VAP)患者醋酸钙不动杆菌感染的流行病学特点.方法前瞻性临床研究分析邵逸夫医院重症监护病房176例连续性发生VAP的病原学诊断结果.分成醋酸钙不动杆菌组和对照组(其他致病茵)，用多元logistic回归法分析醋酸钙不动杆菌引起VAP的危险因素.结果 醋酸钙不动杆菌组26例(26/176，14.7%)，对照组150例(85.2%).统计学分析表明，头颅外伤(OR=4.20，95%CI:2.72～6.48)、外科手术(OR=2.88，95%CI:1.78～4.66)、成人呼吸窘迫征(OR=2.81，95%CI:1.19～6.64)、大量肺误吸(OR=6.71，95%CI:3.91～11.50)是患者并发醋酸钙不动杆菌VAP的高危因素.结论 使用呼吸机的患者感染醋酸钙不动杆菌引起VAP，其流行病学特点不同于其他致病菌，高危因素可能是气道护理时的交叉感染. |

| Objective To study the epidemiology of Acinetobacter baumannii infection in patients with ventilator-associated pneumonia(VAP).Methods Prospective clinical study was carried out with 176 episodes of VAP with etiologic diagnosis being followed in two groups.Results Twenty-six episodes were caused by Acinetobacter baumannii and one hundred-fifty episodes were caused by"other"organisms.Using logistic regression analysis.the risk of VAP due to Acinetobacter baumannii was found to be high in patients with head trauma[odds ratio(OR)=4.20,95% confidence interva(CI):2.72 to 6.48),surgery(OR=2.88, 95%CI:1.78 to 4.66),acute respiratory dispnea syndrom(OR=2.81,95%CI:1.19 to 6.64),and large-volume pulmonary aspiration(OR=6.7 1.95%CI:3.91 to 11.50).Conclusions Acinetobacter baumannii pulmonary infection in incubated patients had an epidemiologica1 pattern that different from "other"organnisms.Patients with high risk identified in our study might mark the existence of cross-infection during airway manipulation. |
