Causes of neonatal death

Not all babies can be born safely. Many babies suffocate and die due to lack of oxygen during childbirth. After the baby is born, he or she will also undergo a health check to ensure that he or she is healthy before being able to go home with his or her parents. Some babies will be diagnosed with many diseases after they are born safely, so pregnant women should have regular prenatal checkups. If any disease is detected during pregnancy, a solution can be found in time. Also pay attention when your baby is sleeping, and do not cover the baby with a quilt that goes above the head.

① Common causes of death are

Asphyxiation factors, infection, hemorrhagic diseases, deformities and obstetric factors, etc.

②Relationship between death and age

The causes of death of newborns of different ages are also different. The causes of death of newborns within 24 hours are as follows: asphyxia, hemorrhagic diseases, premature birth, infectious diseases, malformations and obstetric factors. Newborns who die within seven days: asphyxiation, infectious diseases, hemorrhagic diseases, premature birth. Causes of death from 7 to 28 days: infectious diseases (infectious pneumonia, neonatal sepsis, encephalopathy), malformations, and bilirubin encephalopathy.

③Relationship between cause of death and gestational age

The gestational age of premature infants is 29+5~36+5 weeks, and the causes of death are asphyxiation, hemorrhagic factors, infectious factors, and malformation, respectively; the gestational age of full-term infants is 37+1~41+6 weeks, and the causes of death are asphyxiation, infectious factors, hemorrhagic factors, malformation, and obstetric factors, respectively; the gestational age of post-term infants is 42+4 weeks, and the main cause of death is suffocation.

④ Time structure of neonatal death

The mortality rate of early neonatal death (death within 7 days of birth) is significantly higher than that of late neonatal death (death between 7 and 28 days).

⑤ Gender composition of neonatal mortality

The mortality rate of male newborns is significantly higher than that of female newborns.

⑥Neonatal asphyxia is mostly a continuation of intrauterine asphyxia. Abnormal factors during the mother's pregnancy can cause fetal intrauterine hypoxia. Therefore, it is necessary to strengthen pregnancy care, conduct regular postpartum check-ups, and teach pregnant mothers to self-detect fetal movements. Use a stethoscope to listen to the fetal heart rate and seek medical attention in a timely manner if any problems are found. At the same time, strengthen cooperation between obstetricians and neonatologists to jointly and accurately carry out new methods of resuscitation. Strengthen neonatal care after resuscitation to reduce neonatal mortality. Neonatal asphyxia is caused by hypoxia and ischemia of the fetus and newborn during intrauterine delivery. It is the main cause of perinatal death and brain damage. The longer the hypoxia lasts, the greater the brain damage.
