Cardiopulmonary resuscitation (CPR) in the delivery room (DR) after birth is rare. We hypothesized that factors related to maternal, delivery, infant and resuscitation event characteristics associated with outcomes could be identified. We also hypothesized there would be substantial variation from the Neonatal Resuscitation Program (NRP) algorithm.
Retrospective review of all neonates receiving chest compressions in the DR from the AHA Get With The Guidelines-Resuscitation registry from 2001 to 2014. The primary outcome was return of spontaneous circulation (ROSC) in the DR. Secondary outcome was survival to hospital discharge. Descriptive statistics were used to characterize data. Odds ratios with confidence intervals were calculated as appropriate to compare survivors and non-survivors.
There were 1153 neonates who received chest compressions in the DR. ROSC was achieved in 968 (84%) newborns and 761 (66%) survived to hospital discharge. Fifty-one percent of the cohort received chest compressions without medications. Cardiac compressions were initiated within the first minute of life in 76% of the events, and prior to endotracheal intubation in 79% of the events. In univariate analysis, factors such as prematurity, number of endotracheal intubation attempts, increased time to first adrenaline dose, and CPR duration were associated with decreased odds of ROSC in the DR. Longer CPR duration was associated with decreased odds of ROSC in multivariate analysis.
In this cohort of infants receiving chest compressions following delivery, recognizable pre-birth risk factors as well as resuscitation interventions associated with increased and decreased odds of achieving ROSC were identified. Chest compressions were frequently initiated in the first minute of the event and often prior to endotracheal intubation. Further investigations should focus on methods to decrease time to critical resuscitation interventions, such as successful endotracheal intubation and administration of the first dose of adrenaline, in order to improve DR-CPR outcomes.
出生后在产房(DR)进行心肺复苏(CPR)的情况很少见。我们假设可以识别出与产妇、分娩、婴儿以及复苏事件特征相关的、与结局有关的因素。我们还假设与新生儿复苏项目(NRP)算法会存在很大差异。
对2001年至2014年美国心脏协会“遵循指南-复苏”登记处中所有在产房接受胸外按压的新生儿进行回顾性研究。主要结局是在产房恢复自主循环(ROSC)。次要结局是存活至出院。使用描述性统计来描述数据。适当计算比值比及其置信区间以比较存活者和非存活者。
有1153例新生儿在产房接受了胸外按压。968例(84%)新生儿实现了ROSC,761例(66%)存活至出院。该队列中有51%的新生儿接受了无药物的胸外按压。76%的事件在出生后第一分钟内开始进行心脏按压,79%的事件在气管插管前开始。在单因素分析中,早产、气管插管尝试次数、首次给予肾上腺素的时间增加以及心肺复苏持续时间等因素与在产房实现ROSC的几率降低有关。在多因素分析中,较长的心肺复苏持续时间与ROSC几率降低有关。
在这个分娩后接受胸外按压的婴儿队列中,识别出了出生前可识别的危险因素以及与实现ROSC几率增加和降低相关的复苏干预措施。胸外按压通常在事件发生的第一分钟内开始,且常在气管插管前进行。进一步的研究应侧重于减少关键复苏干预措施(如成功气管插管和首次给予肾上腺素)的时间的方法,以改善产房心肺复苏的结局。
