A new suction catheter, designed to deliver alternately oxygen or suction, prevented episodes of hypoxia and hyperoxia in a group of infants during endotracheal suctioning. Twenty infants received both conventional endotracheal suctioning and suctioning by the new catheter. The infants had a maximal change from a presuctioning transcutaneous oxygen (PtcO2) of 12 +/- 8 torr and required 3.1 +/- 2 min to regain their presuctioning oxygenation level compared to a maximal change of 21 +/- 10 torr (p less than .05) and a stabilization time of 5.3 +/- 2.6 min (p less than .05) in the conventionally treated group. Three study infants experienced an abnormal PtcO2 (either less than 40 or greater than 90 torr), while 13 control infants suffered these abnormalities (p less than .01). The use of this new suction device effectively reduced the exposure of this group of infants to episodes of aberrant oxygen states and allowed for a shorter recovery time.
一种新设计的可交替输送氧气或进行抽吸的吸痰导管，在一组婴儿进行气管内吸痰时预防了低氧血症和高氧血症的发作。20名婴儿既接受了传统的气管内吸痰，也接受了使用新导管的吸痰。与传统治疗组相比，这些婴儿在吸痰前经皮氧分压（PtcO2）的最大变化为12±8托，恢复到吸痰前氧合水平需要3.1±2分钟，而传统治疗组的最大变化为21±10托（p<0.05），稳定时间为5.3±2.6分钟（p<0.05）。3名研究婴儿出现异常的PtcO2（低于40或高于90托），而13名对照婴儿出现这些异常（p<0.01）。使用这种新的吸痰装置有效地减少了这组婴儿暴露于异常氧状态发作的情况，并缩短了恢复时间。
