An alternate tracheal aspiration procedure using a side-hole endotracheal adapter was used in conjunction with transcutaneous oxygen (TcPO2) monitoring in 13 mechanically ventilated newborn infants. Decline in TcPO2 during suctioning and drop in neonatal heart rate were both substantially reduced using a procedure designed to preserve mean airway pressure. When compared with the routine procedure of disconnecting the endotracheal tube from the ventilator and suctioning via an end-hold adapter, this approach prevented precipitous and dangerous hypoxemia.
在13例机械通气的新生儿中，一种使用侧孔气管内适配器的替代气管抽吸程序与经皮氧分压（TcPO2）监测相结合使用。采用旨在维持平均气道压力的程序，抽吸过程中TcPO2的下降和新生儿心率的下降均显著降低。与将气管内导管从呼吸机上断开并通过端部持握适配器进行抽吸的常规程序相比，这种方法可预防急剧且危险的低氧血症。
