ABSTRACT
Objective To analyze the clinical characteristics ,causes of death and their changes of hospitalized neonates so as to provide theoretical basis for improving the level of intensive medical care and reduce neonatal mortality .Methods The clinical data of 108 neonates who died between January 2012 and December 2016 were collected .We compared the mortality rate of neonates with different gestational age ,birth weight ,sex ,family background and abnormal high-risk pregnancy .The causes of death and death rate were analyzed .Results Among the 8869 hospitalized neonates ,108 died and the mortality rate of the neonates was 1 .22% .The avoidable mortality rate of the neonates was 0 .86% and the avoidable mortality ratio was 71 .29% .Infectious diseases remained to be the leading cause of neonatal death in hospitals . The top five most common causes of death in our hospitalized neonates were infectious diseases ,respiratory diseases ,asphyxia ,congenital malformations ,and genetic metabolic diseases .The three most common causes of death in full-term infants were infectious diseases ,genetic metabolic diseases ,and asphyxia . The three most common causes of death in preterm infants were infectious diseases , respiratory diseases ,and asphyxia .The neonatal mortality rate in our hospital decreased from 2 .02% in 2012 to 1 .09% in 2016 .Sepsis was the leading cause of death between 2012 and 2015 and dropped to the third place in 2016 . Respiratory diseases were the leading cause of death in 2016 . Asphyxia was the second cause of death in 2016 . Congenital malformations dropped from the third cause of death to the fifth .Conclusion In recent years ,thetreatment of neonates has improved and mortality rate of hospitalized neonates is gradually decreased .Controlling infectious diseases should be the primary measure to reduce the avoidable mortality in hospitalized neonates .
