本文对8例重度RDS早产儿机械通气时，在吸痰前、吸痰中、吸痰后连续监测动脉血氧饱和度（SaO 2）和心率。每例患儿交替采用两种吸痰方法：A法吸痰前先断开呼吸机，预充氧; B法吸痰前不中断呼吸机，不预充氧，使用专用吸痰接头。虽然在两种手术中，HR和SaO 2在吸痰过程中降低，但在手术B中，心动过缓和动脉血氧饱和度下降的程度在幅度上明显更小，持续时间更短。这些数据表明，吸引适配器在最大限度地减少气道吸引引起的心动过缓和缺氧方面具有优势。
The continuous recordings of arterial oxygen saturation (SaO 2) and beat-to-beat heart rate before, during, and after tracheobronchial suctioning were studied in eight preterm infants with severe RDS receiving mechanical ventilation. Two suctioning procedures were alternatively performed in each infant; In procedure A, disconnection of the ventilator and preoxygenation preceded suctioning; in procedure B, a special suction adaptor was used without ventilatory interruption or preoxygenation; 128 suctionings were performed with each procedure and the changes in heart rate (HR) and SaO 2 during suctioning were compared. Although in both procedures, HR and SaO 2 decreased during suctioning, the degree of bradycardia and arterial blood oxygen desaturation were significantly smaller in magnitude and shorter in duration during procedure B. These data indicate advantages of the suction adaptor in minimizing bradycardia and hypoxia from airway suction.
