The extent of airborne environmental bacterial contamination which occurs following tracheal suction has been investigated in patients undergoing intermittent positive pressure ventilation in the intensive therapy unit. Two methods of performing suction, one using a conventional open technique and one using a closed system (Stericath), have been compared. Significantly lower levels of environmental contamination were observed when the closed system was used.
在重症监护病房接受间歇正压通气的患者中，对气管抽吸后发生的空气传播环境细菌污染程度进行了调查。比较了两种抽吸方法，一种使用传统的开放式技术，另一种使用封闭系统（Stericath）。使用封闭系统时，观察到环境污染水平显著降低。
