Preterm infants with respiratory distress syndrome requiring continuous positive airway pressure are frequently assisted with intermittent bag ventilation. We assessed the effect of intermittent bag ventilation on PO2 in these infants by continuous monitoring with a transcutaneous oxygen electrode. The behavior of the infants during bagging determined the effect on PO2. Bag ventilation decreased PO2 significantly (P less than 0.01) in infants who were restless during bagging, whereas a significant increase in PO2 (P less than 0.02) was observed in infants who were quiet while being bagged. Although the duration of the increase in PO2 was variable, a sustained rise (greater than 20 minute) occurred in almost half of the infants studied. Intermittent bag ventilation appears to be beneficial in infants who remain quiet during the bagging period.
患有呼吸窘迫综合征且需要持续气道正压通气的早产儿常接受间歇性面罩通气辅助。我们通过经皮氧电极连续监测，评估了间歇性面罩通气对这些婴儿动脉血氧分压（PO2）的影响。婴儿在面罩通气时的行为决定了对PO2的影响。在面罩通气时躁动不安的婴儿，面罩通气会使其PO2显著降低（P<0.01），而在面罩通气时安静的婴儿，其PO2则显著升高（P<0.02）。尽管PO2升高的持续时间各不相同，但在近一半接受研究的婴儿中出现了持续升高（超过20分钟）。间歇性面罩通气似乎对在面罩通气期间保持安静的婴儿有益。
