下呼吸道标本的采集运送及处理中应注意的事项王辉
人类口咽部定植着大量的需氧菌和厌氧菌等微生物,口
腔内菌群总数可达1013~1015 CFU/ml。患者因基础条件不
同,如免疫功能抑制、酗酒或慢性肺部疾病及接受广谱抗菌
药物治疗等,其定植菌群的种类也不同。
目前,呼吸道标本是我国临床微生物实验室接收到的最
常见的标本,但此类标本,特别是痰液的采集和送检存在诸
多不规范之处,影响了肺部感染病原菌的诊断,造成抗菌药
物的不合理使用。现结合临床,将此类标本的采集、运送及
处理过程中应注意的事项归纳如下,供临床医生参考。

神经肌肉阻滞剂在严重急性呼吸窘迫综合征早期的应用
Papazian L,Forel JM,Gacouin A,
背景和目的:在因ARDS而接受机械通气的患者中,神
经肌肉阻滞剂有可能改善氧合并减少呼吸机相关肺损伤,但
也可能引起肌无力。我们评估了在严重ARDS的早期,应用
神经肌肉阻滞剂治疗2d后患者的临床转归。方法:在本项
多中心、双盲、随机对照试验中,340 例在既往48 h内因发生
严重ARDS而入住ICU的患者,被随机分配接受48h的苯
磺酸顺阿曲库胺(178例)或安慰剂(162例)治疗。严重
ARDS定义为PaO2/FiO2<150,伴呼气末正压≥5cm H2O
(1 cm H2O=0.098 kPa)及潮气量6~8 ml/kg。主要转归为
出院前或进入研究后90d内死亡患者的比例(即90d院内
病死率),采用Cox模型校正协变量和组间基线差异。
