Objective : To study factors which may caused birth asphyxia and to reduce birth asphyxia rate.

Research method: Retrospective survey study

Subjects : Gestational age 28 weeks or above of pregnant women who were admitted to labor room of Samutsakorn Hospital between October 1, 2005—September 30, 2008. These pregnant women delivered asphyxia newborns (Apgar score at 1 min≤7).

Results : Total of 18,021 pregnant women, 441 of them delivered asphyxia newborn. The prevalence of birth asphyxia rate is 27.9, 20.1, 24.3 : 1,000 live birth in 2006, 2007, 2008 years, respectively. The risk factors which may caused birth asphyxia included general and maternal factors, most of them were 80.2% of 18-34 years old. 65.3% were 37-41 weeks of gestational age, 57.1% were nulliparity, 40.2% good ANC in Samutsakorn Hospital. Pre-delivery factors, most of them (71.7%) had no risk factors. In risk factor groups, 14.6% iron deficiency anemia, 4.9% previous cesarean section. Labor factors, most of them (70.3%) had risk factors, 45.8% medical induction of labor and 10% analgesic (pethidine) were used. Newborn factors, most of them (62.7) had 2,500-3,999 gram body weight, 49.7% had clear amniotic fluid and 7.9% had thick meconium stained amniotic fluid.

Conclusion : Good antenatal care and early detection of risk factors by risk screening system, par- tograph and electronic fetal monitoring used, good resuscitation team can reduce birth asphyxia rate.
