目的应用急性生理学及慢性健康状况评价系统Ⅱ(APACHEⅡ评分)评估重症监护病房(ICU)中呼吸机相关性肺炎(VAP)的发生、危重程度,以及入住ICU的时间和预后。方法将入住ICU且行机械通气的113例患者分成两组,出现VAP的63例患者设为发病组,未出现VAP的50例患者设为未发病组,按Knaus法进行APACHEⅡ评分,并进行临床对比。结果发病组和未发病组的APACHEⅡ评分,住院时间和病死率差异有统计学意义。随APACHEⅡ分值的升高,患者出现VAP、重症肺炎例数增多,病死率升高。结论在ICU病人尤其是机械通气的患者中,APACHEⅡ评分系统有助于预测患者VAP的发生,评估病情的严重性、住院时间和预后。
Objective To evaluate the incidence and severity of ventilator - associated pneumonia (VAP) in intensive care unit (ICU) and the time and prognosis of ICU admission by using the Acute Physiology and Chronic Health Evaluation System Ⅱ (APACHE Ⅱ). Methods One hundred and thirteen patients admitted to ICU with mechanical ventilation were divided into two groups. 63 patients with VAP were selected as the disease group, 50 patients without VAP as the non-disease group, APACHEⅡ score by Knaus method and clinical comparison . Results The APACHEⅡscore, length of hospital stay and case fatality rate in the diseased group and non-diseased group were significantly different. With APACHE Ⅱ score increased, patients with VAP, increased incidence of severe pneumonia, increased mortality. Conclusions Among ICU patients, especially patients with mechanical ventilation, the APACHE II scoring system can help predict the occurrence of VAP in patients and assess the severity of illness, length of hospital stay and prognosis.
