摘　　要：背景妊娠期肝内胆汁淤积症(ICP)可能导致新生儿不良结局。目的探讨ICP孕妇分娩的新生儿生后24 h内入住新生儿重症监护室(NICU)的危险因素。设计单中心病例对照研究。方法纳入2015年1月至2019年12月在重庆市永川区妇幼保健院娩出、母亲明确诊断ICP且本次为单胎妊娠的新生儿,根据其生后24 h内是否入住NICU分为住院组和非住院组,样本量计算显示每组至少需要131例新生儿。截取母亲孕期及分娩时资料、新生儿资料以及生后24 h内入住NICU情况和原因。采用二元Logistic回归分析影响ICP孕妇分娩的新生儿入住NICU的独立危险因素,构建ROC曲线评估这些危险因素对新生儿入住NICU的预测价值。主要结局指标ICP孕妇分娩的新生儿NICU住院的影响因素及预测因素。主要结局指标ICP孕妇分娩的新生儿NICU住院的影响因素及预测因素。结果ICP孕妇娩出的新生儿621例,平均胎龄38.3(37.0,39.3)周,平均出生体重3148±461)g,男308例。生后24 h内入住NICU(住院组)133例(21.4%),主要原因包括早产(78例)、呼吸窘迫(20例),低血糖、反应差和感染等;非住院组488例。住院组胎龄、出生体重、5 min Apgar评分、母亲诊断ICP的孕周均小于或低于非住院组,母亲分娩前最后1次ALT、AST、胆汁酸水平和新生儿早产率均高于非住院组,差异均有统计学意义。新生儿均随访至生后28 d,死亡1例(0.16%)。二元Logistic回归分析显示,胎龄小(OR=0.378,95%CI:0.301~0.474,P<0.001),母亲孕期皮肤瘙痒(OR=2.410,95%CI:1.411~4.114,P=0.001)、胆汁酸水平高(OR=1.016,95%CI:1.003~1.028),P=0.012)和母亲产前BMI低(OR=0.930,95%CI:0.873~0.990,P=0.023)是新生儿生后需要NICU住院治疗的危险因素.ICP孕妇分娩的新生儿生后24 h内入住NICU的预测因素及性能:ICP母亲伴孕期皮肤瘙痒症状时,新生儿胎龄(最佳诊断界值≤36.6周)、母亲胆汁酸水平(最佳诊断界值>20μmol·L^(-1))和产前BMI(最佳诊�Background Intrahepatic cholestasis of pregnancy(ICP)may lead to adverse neonatal outcomes.Objective To investigate the risk factors of Neonatal Intensive Care Unit(NICU)admission of newborns delivered by mothers with ICP within 24 hours after birth.Design Single-center case-control study.Methods From January 2015 to December 2019,the newborns whose mothers gave birth to a single baby at Maternal and Child Health Hospital of Chongiqng Yongchuan District and were diagnosed with ICP were selected as the study subjects.According to whether they were admitted to NICU within 24 hours of life,they were divided into NICU admission group and non-NICU admission group.Sample size was estimated that 131 newborns would be needed at least in each group.The clinical data of mothers and newborns were retrospectively analyzed,and the risk factors of NICU admission within 24 hours of life were analyzed by binary logistic regression model.Receiver operating characteristic(ROC)curve was used to predict the the independent risk for the NICU admission factors.Main outcome measures The risk factors and predictive factors of NICU admission of newborns delivered by mothers with ICP within 24 hours of life.Results A total of 621 newborns(308 males)delivered by mothers with ICP were included.The average gestational age was 38.3(37.0,39.3)weeks,and the average birth weight was 3148±461 g.There were 133(21.4%)newborns admitted to NICU within 24 hours of life because of preterm(n=78),respiratory distress(n=20),hypoglycemia,poor response,infection and 488 newborns were not admitted to NICU.Compared with the non-NICU admission group,the gestational age,birth weight,5 min Apgar score and gestational age at diagnosis of the NICU admission group were lower,and the ALT,AST,bile acid of last test,and preterm of the NICU admission group were higher,and the differences were statistically significant.One(0.16%)newborn died at follow-up within 28 days of life.Logistic regression analysis showed that small gestational age(OR=0.378,95%CI:0.301-0.474,P<0
