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 < .05) and a stabilization time of 5.3 ± 2.6 min (p < .05) in the conventionally treated group. Three study infants experienced an abnormal PtCO2 (either <40 or >90 torr), while 13 control infants suffered these abnormalities (p < .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.
