自然分娩与剖宫产新生儿脐动脉血气体酸碱测定与比较

COMPARISON OF BLOOD GAS ACID-BASE DETERMINATION OF UMBILICAL ARTERY BLOOD ABOUT THE NEONATE OF SPONTANEOUS LABOUR AND CESAREAN BIRTH

随着血气分析在临床的广泛应用,为探讨自然分娩与剖宫产新生儿血气酸碱指标的差异,应用瑞士AVL-945血气分析仪,对61例剖宫产与48例自然分娩新生儿pH、PCO_3、PO_2和HCO_3^-4项指标作了测定与比较.结果表明,剖宫产组与自然分娩组比较,PCO_2、HC0_3^-两项指标差异具有显著性.剖宫产组酸中毒程度轻于自然分晚组,提示剖宫产是缩短产程、避免新生儿因缺氧窒息的重要措施.pH两组差异虽无显著性,也轻于自然分娩组.测定结果除对新生儿抢救与治疗提供了客观依据外,对于破除“剖宫产不利于母婴健康”的旧观念,也提供了一些理论根据.

To probe the difference of blood gas acid-base value between the neo-nate of spontaneous labour and cesarean birth, the values of 4 itmes pH, PCO2, PO2 and HCO3-, the neonate of 61 cases cesarean birth and 48 cases spontaneous labour had been determined with the blood gas analysis system of Swiss AVL-945. The results showed that the differences of the values of PO2 and HCO3- between the group of cesarean birth and spontaneous labour was obvious.The acidosis degree in the group of cesarean birth was lighter than in that of spontaneous labour. It indicated that cesarean birth was the important method for shortening the labour course and avoiding the neonate getting hypoxia asphyxia. Although there weren't notable differences in pH and PO2 group,the degrees of acidosis were not the same and that of cesarean birth was lighter than that of spontaneous labour. The determination results not only give the objective evidences for rescuing and curing neonate but also furnish theoretical basis for getting rid of the old idea 'Cesarean birth is bad for the health of mother and infant'.
