Principales factores de riesgo de la morbilidad y mortalidad neonatales / Main risk factors of neonates morbidity and mortality

Se revisó la bibliografía disponible sobre la morbilidad y mortalidad neonatales, tanto nacional como foránea y se decidió hacer referencia a importantes aspectos relacionados con el tema, entre los cuales figuraron, además de una reseña histórica: clasificación y registro de las causas de muerte (síndrome de dificultad respiratoria, enfermedad de la membrana hialina, infecciones, displasia broncopulmonar y malformaciones congénitas), tipo de parto (complicaciones y prematuridad), así como bajo peso al nacer. De la información obtenida se infirió que el nacimiento de neonatos con insuficiencia ponderal para la edad gestacional, todavía constituye una grave situación de salud en el mundo de hoy, sobre todo en los países tercermundistas, donde no se dispone de recursos suficientes para brindar una adecuada asistencia sanitaria a la población.

The available literature either national or foreign about the neonate morbidity and mortality was reviewed and it was decided to make reference to important aspects related with the topic, among which there were figured, besides a historical review: classification and register of the death causes (distress syndrome, hyaline membrane disease, infections, bronchopulmonary dysplasia and congenital malformations), delivery type (complications and prematurity), as well as low birth weight. Of the obtained information it was inferred that the neonates birth with ponderal inadequacy for the gestational age, still constitutes a severe health situation in today's world, mainly in the third world countries, where enough resources are nor disposable to offer an appropriate health care to the population.

Neonatal mortality and death causes in hospital patients from 2012 to 2016 / 西安交通大学学报(医学版)

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 .
