摘  要:目的了解甲型H1N1流感(甲流)危重症患者的临床特点,分析其死亡相关危险因素。方法采用多中心研究方法,回顾性分析郑州市4家医院2009年10月至2010年2月住院的128例甲流危重症患者的临床数据,比较存活组(110例)与死亡组(18例)患者的临床特点;对年龄〉14岁的成人患者,以性别、是否妊娠、基础疾病数量、心率、平均动脉压、pH值、动脉血氧分压(PaO2)、氧合指数(PaO2/FiO2)、是否有呼吸衰竭、是否出现急性呼吸窘迫综合征(ARDS)、单肺或双肺病变、是否使用糖皮质激素作为变量进行二元Logistic回归分析,探讨甲流危重症患者死亡的相关危险因素。结果128例患者中孕妇病死率显著高于儿童和成人非孕妇患者[37.5%(6/16)比12.5%(4/32)、10.0%(8/80),P=0.044和P=0.0003。死亡组呼吸衰竭、ARDS、有创机械通气、有合并症的比例(分别为83.3%、33.3%、66.7%、77.8%)及心率[(114±25)次/mini均显著高于生存组[37.3%、9.1%、12.7%、51.8%、(101±21)次/mini;pH值、PaO2(mmHg,1mmHg=0.133kPa)、Pa02/Fi02(mmHg)均显著低于生存组(pH值:7.149±0.404比7.398±0.157,PaO2:58.57±36.85比85.78±36.10,PaO2/FiO2:118.17±105.52比259.25±174.91);使用糖皮质激素的比例多于生存组(77.8%比36.4%,P〈0.01),且使用时间(d)明显长于生存组(8.3±8.0比2.6±4.2,P〈0.05)。Logistic回归分析显示,妊娠[相对比值比(OR)为6.642,P=0.011]及ARDS(OR=10.603,P=0.001)是成人甲流危重症患者的死亡危险因素。结论在甲流危重症患者中,孕妇的死亡比例高于其他患者;有呼吸衰竭、特别是ARDS患者和需要有创机械通气治疗者、有合并症者的死亡比例显著增加;死亡患者发病初期心率明显增快。糖皮质激素的过度�Objective To learn the clinical characteristics and risk factors associated with death of the critically ill patients with 2009 influenza A H1N1. Methods Retrospective analyses of clinical features of 128 hospitalized patients with critically ill influenza A H1N1 infection in four hospitals in Zhengzhou city in October 2009 to February 2010, including 110 survival cases and 18 dead cases, were conducted. Among patients 〉14 years of the sexual difference, pregnancy or non-pregnancy, the number of underlying diseases, heart rate, mean arterial pressure, pH, arterial partial pressure of oxygen (PaO2), oxygenation index (PaO2/FiO2), incidence or no incidence of respiratory failure, presence or absence of acute respiratory distress syndrome (ARDS), unilateral or bilateral lung disease and with or without glucocorticoid administration were the variables, and the binary Logistic regression was applied to analyze the risk factors related to death of such patients. Results In 128 patients, the mortality of pregnant women was significantly higher than that of children or adult non-pregnant women [37.5% (6/16) vs. 12.5% (4/32), 10. 0% (8/80), P=0. 044 and P=0. 000]. The incidences of respiratory failure, ARDS, using invasive ventilator, complications (83.3%, 33.3%, 66.7%, 77.8%) and heart rate [(114i25) bpm] in patients in non-survival group were significantly higher than those in patients of survival group (37.3%, 9.1%, 12.7%, 51.8%, (101±21) bpm]; however, pH, PaO2(mm Hg, 1 mm Hg=0. 133 kPa) and PaO2/FiO2 (mm Hg) were significantly lower than those in survival patients (pH: 7. 149±0. 404 vs. 7. 398±0. 157, PaO2: 58. 57±36.85 vs. 85. 78±36.10, PaO2/FiO2: 118.17 ± 105.52 vs. 259.25 ±174. 91). In the death group, the percentage of patients having used corticosteroids (77, 8% vs. 36.4%, P〈0. 01) was higher and the time of administration (days, 8.3 ± 8.0 vs. 2.6±4.2, P〈0. 05) longer than those in patients of survival group.
