Abstract 【Abstract】 Objective To explore the effects of two different delivery methods on umbilical artery blood gas analysis of infants and the potential effects on neonatal asphyxia. Methods From October 2016 to January 2017, 94 women who delivered at term in Northern Theater General Hospital and Peace Branch without gestational complication were selected and divided into cesarean section group (41 cases) and vaginal delivery group (53 cases), the blood gas analysis results of umbilical artery of the two groups were analyzed. Results The pH of umbilical artery (7.23±0.12) and arterial partial pressure of oxygen (PaO2) value[(24±13) mmHg, 1 mmHg=0.133 kPa] of newborn in cesarean section group were higher than those invaginal delivery group [(7.19±0.10) and (21±15) mmHg, respectively], the differences were statisticallysignificant (P<0.01). Arterial partial pressure of carbon dioxide (PaCO2) [(52±10) mmHg] and lactate[(3.4±1.3) mmol/L] of umbilical artery in cesarean section group were lower than those in vaginal deliverygroup [(57±10) mmHg and (5.0±2.3) mmol/L, respectively], with statistically significant differences(P<0.01). The incidence rate of umbilical arterial blood pH<7.15 (4.9%) in the cesarean section group waslower than that in the vaginal delivery group (24.5%), the difference was statistically significant (P<0.05).The incidence of acidosis in the cesarean section group (4.9%) was lower than that in the vaginal deliverygroup (24.5%), and the difference was statistically significant (P<0.05). The abnormal rate of lactic acid innewborns in the cesarean section group (17.1%) was lower than that in the vaginal delivery group (47.2%),and the difference was statistically significant (P<0.01). Conclusion The risk of neonatal acidosis may be reduced in cesarean section compared with vaginal delivery in the cases of abnormal labor process, suspicious fetal distress, and complications of mother and child.
