Analysis of 10-year early neonatal death in the NICU / 中华急诊医学杂志

ABSTRACT

Objective To analyze the main causes of early neonatal death in Qingdao Women &Children's Hospital in the latest 10 years.Methods The medical records of early neonatal death in the Qingdao Women&Children’s Hospital from January 2002 through December 201 1 were analyzed.Results A total of 16 314 neonates were available to study,and 525 of them died.The mortality of early neonatal death within a week after birth was 77.71% (408 cases),including 214 premature infants and 194 mature infants.A comparison of mortality between the first 5-year and the second 5-year showed that the underlying trend of mortality was downward (P <0.05 ).The mortalities of early neonatal death within 1 day,3 days, and 4-7 days after birth were 1 10 cases (27.00%),192 cases (47.06%),and 106 cases (25.98%), respectively,and most of the neonates died within 3 days after birth;and the number of severe neonates died within 24 hours was higher than that in other two groups (P <0.01).The leading causes of early neonatal death in 10 years were:preterm birth-related factors (97 cases,23.78%),severe asphyxia (91 cases, 22.3%),congenital malformations (66 cases,16.2%).From 2002 to 2006,the top three main causes of early newborn death were severe asphyxia,congenital malformations and acute respiratory distress syndrome (ARDS),whereas from 2007 to 2011,the leading causes of death were ARDS,severe asphyxia,and congenital malformations.In comparison of early neonatal death between different gestational ages,preterm infants’death occurred mainly in 32 weeks,accounting for 26.72%.Conclusions In our hospital,the early neonatal mortality was decreased in the latest 10 years,and majority of deaths occurred within 3 days after berth,and preterm infants’death occurred mainly in 32 weeks.The leading causes of overall early neonatal death in order of frequency were premature birth,severe asphyxia and congenital malformations,but in later 5 years this order of leading causes changed.
