　　[Abstract] Objective To investigate the effect of cesarean section delivery time on umbilical arterial blood gas and Apgar score. Methods A total of 318 puerpera undergoing selective cesarean section were eolled in this study. Participants were divided into three groups according to Apgar grading standards： 0 to 3 as severe asphyxia group， 4 to 7 as mild asphyxia group and 8 to 10 as the control group. The delivery time， 1 min Apgar score， umbilical arterial blood gas analysis and lactic acid value were compared among the three groups. The correlation of delivery time with blood gas and Apgar score were also analyzed. Results Among 318 neonates， there were 3 cases of severe asphyxia with a delivery time of（186.20±12.00）s， 12 cases of mild asphyxia with a delivery time of（107.0±16.72）s， and 303 normal cases with a delivery time of（45.50±8.06）s， the difference was statistically significant（P<0.05）. The blood gas analysis of umbilical arteries showed that the differences of pH， PaCO2， PaO2， Lac and BE value were statistically significant among three groups（P<0.05）. There was a negative correlation between delivery time and pH of neonatal umbilical artery（r=-0.491， P=0.0017）. There was a positive correlation between delivery time and neonatal umbilical artery Lac value（r=0.652， P<0.001）. Conclusion During cesarean section， the delivery time should be limited within 120 s as much as possible， which can significantly reduce the incidence of neonatal asphyxia.

　　新生兒窒息是導(dǎo)致新生兒死亡、腦損傷的主要原因之一。新生兒窒息發(fā)病機(jī)理是低氧血癥和酸中毒引發(fā)的多臟器功能損害，大多數(shù)伴隨著神經(jīng)系統(tǒng)后遺癥[1]。早期及時預(yù)防對于減少新生兒致殘甚至死亡尤為重要[2]。在剖宮產(chǎn)手術(shù)中影響新生兒窒息因素較多，取胎時限是其中一個重要因素[3]，如發(fā)生取胎困難，將會明顯增加新生兒窒息發(fā)生率及產(chǎn)婦損傷[4]。目前國內(nèi)外關(guān)于剖宮產(chǎn)取胎時限的研究較少，且缺乏可應(yīng)用于臨床的相關(guān)指標(biāo)。該研究收集2014年4月～2015年12月在我院婦產(chǎn)科出生的318例新生兒的信息，分析取胎時限對臍動脈血?dú)釧pgar 評分的影響，并以此試探討取胎時限的范圍。
