s one of the diagnostic standard in the diagnosis of neonatal asphyxia. With the use of portable blood gas analyzer, the domestic scholars also carried out some research, but now we still have not put the umbilical arterial blood gas as a standard of diagnosis of neonatal asphyxia, so it is still using the traditional Apgar score. The prognosis of suffocation son has always been the focus of attention, studies have shown that umbilical cord blood p H value have interdependent relationship with prognosis. Using umbilical cord blood blood gas analysis predict early perinatal hypoxic ischemia, complementary and Apgar score, can improve the choke in the perinatal period diagnosis accuracy, reducing perinatal mortality and incidence of mental disabilities, improve the birth population quality. Based on the above understanding we randomly 344 cases of our hospital childbirth neonatal umbilical artery blood gas analysis immediately; Newborn themselves before crying after nearly end a fetus umbilical cord clamp, about 15 cm from the placenta and neonatal cycle, this period of human cord blood gas due to sampling before spontaneous breathing has not been established, can objectively reflect the fetal blood gas changes end; And routine for childbirth neonatal Apgar score, by analyzing the umbilical artery blood gas, Apgar score in that estimate the prognosis of neonatal asphyxia and clinical significance, for the umbilical arterial blood gas analysis in the experimental foundation for clinical application.
Asphyxia newborn babies all over the world is one of the leading causes of death, cerebral palsy and mental retardation. Estimate that 23% of 4 million newborns die each year around the world, and at the age of death < 5, 8% of children with birth asphyxia. Referral center, even in developed countries, severe HIE is 54-62% will happen or cause of death and severe disability. According to China's maternal and child health monitoring shows that 2000 children under the age of five years ago the three causes of death in our country for pneumonia, birth asphyxia, preterm birth and low birth weight, neonatal asphyxia as the second cause of death, infectious disease under control in the city after birth asphyxia has become the first cause of death. 2005 years ago, three died because of premature birth, birth asphyxia and pneumonia, suffocation is still as the second cau
