Chest:遵从VAP预防指南可显著减少呼吸机相关疾病的患病率和死亡率

2013-11-07 sd3212 dxy

呼吸机相关事件(VAC)、以及与呼吸机相关并发症有关的感染(iVAC)是疾病控制和预防中心对机械通气患者监控新模式的重点内容。但有关VAC和iVAC对临床的影响、及其可预防性、以及VAC和iVAC与呼吸机相关肺炎(VAP)的联系等,人们仍知之甚少。为了加深对上述问题的认识,来自加拿大安大略省金斯敦市女王大学医学院、金斯顿总医院的J. Muscedere及其同事进行了一项研究,研究结果在线发表于20

该研究是对一项前瞻性时间序列研究中,有关VAC和iVAC数据所进行的回顾性分析。研究所采用数据主要来自北美地区11个已经实施了VAP相关临床实践指南的重症监护病房(ICU)。这11个ICU在4个研究周期内,每周期均连续入选30例机械通气时间>48小时的患者。研究者收集了这些患者的预后数据,以及ICU所使用相关预防措施与指南推荐措施是否一致的数据;并计算出了受试者VAC,iVAC,以及VAP等随时间推移的发生率。此外,研究者还对上述各状况之间的一致性(Kappa统计),相关的发病率和死亡率,及其各自独立的危险因素等进行了分析。

该研究的主要结果为:在所有入选的1320例患者中,共有139例(10.5%)出现了VAC,65例(4.9%)发生了iVAC,并有148例(11.2%)出现了VAP。Kappa分析显示:VAP和VAC之间的一致性是0.18,VAP和iVAC之间的一致性是0.19。出现了VAC、或iVAC的受试者,与那些无上述情况的受试者相比,其呼吸机使用天数、住院天数、以及抗生素使用天数等指标均显著延长;而且其住院死亡率也明显更高。此外,研究还发现,ICU对VAP预防指南依从性的增加与受试者VAP和VAC发生率的减少有相关性,但与iVAC的发生率无相关性。

该研究结果显示:VAC和iVAC的发生与呼吸机使用者相关疾病的患病率和死亡率上升显著相关。虽然VAC、 iVAC、以及 VAP 之间的Kappa统计显示出较差的一致性,但更多地遵从VAP预防指南措施,与患者VAP和VAC发生率的降低明显相关。
