近年来,新生儿复苏用氧的观点发生了巨大变化。2005年,新生儿复苏指南提出,在某些情况下,应用低于100%浓度氧气进行复苏是合理的。多个研究也陈述100%氧复苏并不比空气复苏有益。Vento等证实高氧暴露可使血清氧化标记物浓度升高,并持续至生后28d,故复苏过程中短时间的高氧暴露也会对患儿产生持续的影响。由于早产儿与足月儿在分娩过程中肺生理及抗氧化能力不同,空气 In recent years, there has been a dramatic change in the perspective of neonatal resuscitation with oxygen. In 2005, guidelines for neonatal resuscitation suggested that in some cases it would be reasonable to use less than 100% oxygen for resuscitation. Several studies have also stated that 100% oxygen resuscitation is no better than air resuscitation. Vento and other confirmed hyperoxia exposure can make serum oxidized markers increased concentration and lasted 28 days after birth, so the recovery process of short duration of high oxygen exposure will have a sustained impact on children. As premature children and term infants in the delivery process of lung physiology and antioxidant capacity, air
