The approach to intrapartum and postnatal management of an infant born through meconium-stained amniotic fluid (MSAF) in the delivery room (DR) has changed several times over the last few decades, leading to confusion and anxiety among health care providers (nurses, nurse practitioners, respiratory therapists, midwives, and physicians). This article provides state-of-the-art insight into the evidence or lack thereof for the changes in guidelines.
To discuss the evidence for evolution of DR management of vigorous and nonvigorous infants born through any type of MSAF.
Review of guidelines from the Neonatal Resuscitation Program of the American Academy of Pediatrics and the American College of Obstetricians and Gynecologists, the International Liaison Committee on Resuscitation, Consensus on Science and Treatment Recommendations, and textbooks of neonatal resuscitation and research using MEDLINE via PubMed.
In pregnancies complicated by MSAF, intrapartum suctioning of the oro- and nasopharynx and postnatal intubation with tracheal suctioning of infants have been traditionally used to clear the airway and decrease meconium aspiration syndrome. The recommendations for these perinatal practices have changed several times due to some evidence that the procedures are not beneficial and may even be harmful.
Intrapartum suctioning and postnatal tracheal suctioning of infants (vigorous or nonvigorous) born through MSAF are not recommended. This is a "high-risk" delivery requiring 2 team members to be present at birth-one with full resuscitation skills including tracheal intubation.
Need to evaluate effects of discontinuing the practice of tracheal suctioning in nonvigorous infants on the incidence of meconium aspiration syndrome and neonatal mortality.
在过去几十年里,产房(DR)对通过胎粪污染羊水(MSAF)出生的婴儿进行产时和产后管理的方法几经变化,这给医护人员(护士、执业护士、呼吸治疗师、助产士和医生)带来了困惑和焦虑。本文深入探讨了指南变化的现有证据或缺乏证据的情况。
讨论通过任何类型的MSAF出生的活力婴儿和非活力婴儿在产房管理演变的证据。
通过PubMed检索MEDLINE,回顾美国儿科学会新生儿复苏项目、美国妇产科医师学会、国际复苏联合委员会、科学与治疗建议共识以及新生儿复苏和研究教材中的指南。
在合并MSAF的妊娠中,传统上采用产时口鼻咽部吸引和产后对婴儿进行气管插管并吸引以清理气道并减少胎粪吸入综合征。由于一些证据表明这些操作并无益处甚至可能有害,这些围产期实践的建议已多次改变。
不建议对通过MSAF出生的婴儿(无论活力与否)进行产时吸引和产后气管吸引。这是一种“高风险”分娩,需要两名团队成员在出生时在场——其中一人具备包括气管插管在内的全面复苏技能。
需要评估停止对非活力婴儿进行气管吸引操作对胎粪吸入综合征发病率和新生儿死亡率的影响。
