Neonatal asphyxia accounts for a quarter of neonatal deaths. We aimed to assess factors associated with mortality among asphyxiated neonates in a low-resource setting.
A retrospective observational study evaluating all neonates who were admitted for asphyxia to the Neonatal Intensive Care Unit (NICU) at Tosamaganga Hospital (Tanzania) in 2017-2018. Inclusion criteria were: Apgar score <7 at 5 min and/or failure to initiate spontaneous breathing and/or presence of sentinel events and/or clinical signs suggesting encephalopathy not explained by other obvious factors or early convulsions. Newborns with congenital malformations, birth weight <2000 g or those who died in the delivery room were excluded.
NICU admission for perinatal asphyxia was 17.5%. In 169 neonates, mortality rate was 23% and was associated with being outborn, low 5-minute Apgar score, depressed clinical status at NICU admission, occurrence of infection or seizures within 24 h from admission, and receiving aminophylline during the hospital stay.
Perinatal asphyxia was responsible for a relevant proportion of NICU admissions and neonatal deaths in a low-resource setting. Appropriate clinical examination remains the main asset in settings with limited availability of diagnostic tools. Improvements in antenatal and perinatal care are needed to reduce mortality in asphyxiated newborns. Future studies should assess long-term outcome in survivors.
新生儿窒息占新生儿死亡的四分之一。我们旨在评估资源匮乏环境下窒息新生儿死亡的相关因素。
回顾性观察性研究,评估了 2017-2018 年在坦桑尼亚 Tosamaganga 医院新生儿重症监护病房(NICU)因窒息而入院的所有新生儿。纳入标准为:5 分钟时 Apgar 评分<7,或未能自主呼吸,或存在警示事件,或存在提示脑病的临床体征,但不能用其他明显因素或早期惊厥解释,或有先天性畸形、出生体重<2000g,或在产房死亡的新生儿。
围产期窒息导致 NICU 入院率为 17.5%。在 169 例新生儿中,死亡率为 23%,与以下因素相关:外出分娩、5 分钟时 Apgar 评分低、NICU 入院时临床状况不佳、入院后 24 小时内发生感染或惊厥,以及住院期间接受氨茶碱治疗。
在资源匮乏的环境中,围产期窒息是导致 NICU 入院和新生儿死亡的一个重要原因。在诊断工具有限的情况下,适当的临床检查仍然是主要手段。需要改善产前和围产期护理,以降低窒息新生儿的死亡率。未来的研究应评估幸存者的长期预后。
