摘要
背景:先天性膈疝(CDH)具有很高的死亡率,特别是在低收入和中等收入国家。本研究旨在调查越南CDH新生儿的死亡率及其相关因素。方法:这项回顾性观察性研究纳入了2021年11月至2023年9月期间在越南一家中心儿童医院住院的CDH新生儿。我们收集了新生儿的特征、管理、并发症和结局的数据,并将这些数据在幸存者和非幸存者之间进行比较。我们还采用逻辑回归分析来确定与住院死亡率相关的因素。结果:74例新生儿CDH中,男性占64.9%(48/74)。住院死亡率为50.0%(37/74)。出生时中位胎龄为38周(四分位数差[IQR]: 38-39),入院时中位年龄为5.2 h (IQR: 3.0-15.8)。所有新生儿都是从以前的不同医院转介的,83.8%(62/74)的新生儿需要产后立即插管。新生儿表现为危重状态,入院时平均肺动脉收缩压(PASP)为51.7 mmHg(标准差:18.3),6 h时平均氧合指数为13.3 (IQR: 6.8-28.2)。手术重症监护病房期间血管活性肌力评分(VIS)的中位峰值为35.0 (IQR: 15.0-80.0)。52.7%(39/74)的病例采用高频振荡通气作为初始通气方式。支持治疗包括血管加压药物(84.9%;62/73)、肌力药物(29.6%;21/71)、吸入一氧化氮(13.5%;10/74)、伊洛美定(29.7%;19/64)和体外膜氧合(6.8%;5/74)。70.3%(52/74)的新生儿接受手术修复。多变量logistic回归分析发现,较高的VIS峰(调整优势比[AOR]: 1.061; 95%可信区间[CI]: 1.011-1.113; p = 0.017)和较高的入院PASP (AOR: 1.140; 95% CI: 1.041-1.247; p = 0.005)是住院死亡率的独立预测因子。结论:在越南一家中心儿童医院收治的CDH新生儿队列中,观察到较高的医院死亡率。研究结果表明,获得新生儿重症监护和手术修复的机会有限可能会影响结果,需要在类似资源有限的环境中进一步评估以改进护理策略。试验注册:不适用。
Clinical characteristics and outcomes of neonates with congenital diaphragmatic hernia at the Vietnam National Children's Hospital: a retrospective observational study.
Background: Congenital diaphragmatic hernia (CDH) has a high mortality rate, particularly in low- and middle-income countries. This study aimed to investigate mortality rates and associated factors in CDH neonates in Vietnam.
Methods: This retrospective observational study included CDH neonates admitted to a central children's hospital in Vietnam between November 2021 and September 2023. We collected data on neonates' characteristics, management, complications, and outcomes, comparing these data between survivors and non-survivors. We also employed logistic regression analysis to identify factors associated with hospital mortality.
Results: Of 74 neonates with CDH, 64.9% (48/74) were male. The hospital mortality rate was 50.0% (37/74). The median gestational age at birth was 38 weeks (interquartile range [IQR]: 38-39), and the median age at admission was 5.2 h (IQR: 3.0-15.8). All neonates were referred from various prior hospitals, with 83.8% (62/74) requiring immediate postnatal intubation. The neonates presented in critical condition, as reflected by a median pre- and post-ductal SpO2 difference of 2.5% (IQR: 1.0-10.0), a mean pulmonary artery systolic pressure (PASP) of 51.7 mmHg (standard deviation: 18.3) on admission, and a median Oxygenation Index at 6 h of life of 13.3 (IQR: 6.8-28.2). The median peak Vasoactive Inotropic Score (VIS) during surgical intensive care unit stay was 35.0 (IQR: 15.0-80.0). High-frequency oscillatory ventilation was used as the initial ventilatory mode in 52.7% (39/74) of cases. Supportive therapies included vasopressors (84.9%; 62/73), inotropic agents (29.6%; 21/71), inhaled nitric oxide (13.5%; 10/74), Ilomedin (29.7%; 19/64), and extracorporeal membrane oxygenation (6.8%; 5/74). Surgical repair was performed in 70.3% (52/74) of neonates. Multivariable logistic regression analysis identified higher peak VIS (adjusted odds ratio [AOR]: 1.061; 95% confidence interval [CI]: 1.011-1.113; p = 0.017) and elevated admission PASP (AOR: 1.140; 95% CI: 1.041-1.247; p = 0.005) as independent predictors of hospital mortality.
Conclusions: In this selected cohort of CDH neonates admitted to a central children's hospital in Vietnam, a high hospital mortality rate was observed. The findings suggest that limited access to neonatal intensive care and surgical repair may have influenced outcomes, warranting further evaluation in similar resource-limited settings to improve care strategies.
