Many common care practices during labor, birth, and the immediate postpartum period impact the fetal to neonatal transition, including medication used during labor, suctioning protocols, strategies to prevent heat loss, umbilical cord clamping, and use of 100% oxygen for resuscitation. Many of the care practices used to assess and manage a newborn immediately after birth have not proven efficacious. No definitive outcomes have been obtained from studies on maternal analgesia effects on the newborn. Although immediate cord clamping is common practice, recent evidence from large randomized, controlled trials suggests that delayed cord clamping may protect the infant against anemia. Skin-to-skin care of the newborn after birth is recommended as the mainstay of newborn thermoregulation and care. Routine suctioning of infants at birth was not been found to be beneficial. Neither amnioinfusion, suctioning of meconium-stained babies after the birth of the head, nor intubation and suctioning of vigorous infants prevents meconium aspiration syndrome. The use of 100% oxygen at birth to resuscitate a newborn causes increased oxidative stress and does not appear to offer benefits over room air. This review of evidence on newborn care practices reveals that more often than not, less intervention is better. The recommendations support a gentle, physiologic birth and family-centered care of the newborn.
分娩、生产及产后即刻的许多常见护理措施会影响胎儿到新生儿的过渡,包括分娩期间使用的药物、吸引操作规范、预防热量散失的策略、脐带结扎以及复苏时使用纯氧。许多出生后立即用于评估和管理新生儿的护理措施尚未被证明有效。关于母体镇痛对新生儿影响的研究尚未得出明确结果。尽管立即结扎脐带是常见做法,但大型随机对照试验的最新证据表明,延迟结扎脐带可能会保护婴儿预防贫血。建议出生后对新生儿进行皮肤接触护理,这是新生儿体温调节和护理的主要方式。未发现出生时常规抽吸婴儿有益。羊膜腔灌注、胎头娩出后对胎粪污染婴儿的抽吸,以及对活力良好婴儿的插管和抽吸均不能预防胎粪吸入综合征。出生时使用纯氧复苏新生儿会增加氧化应激,且似乎并不比空气复苏更具优势。对新生儿护理措施证据的综述表明,通常情况下,干预越少越好。这些建议支持温和的生理性分娩以及以家庭为中心的新生儿护理。
