本研究的目的在于阐明宫内缺氧和酸中毒在自然分娩与引产分娩时对脐带血中肾上腺皮质醇浓度的影响.本研究包括1978年在Helsinki州立产科医院经阴道分娩的108例足月婴儿.其中86例自然分娩,22例用催产素引产分娩,所有的胎儿临产时均用心动描记法作监护,并进行了脐带血浆中游离肾上腺皮质醇浓度和脐动脉血pH水平的测定.胎儿娩出后立即用两把血管钳夹住脐带,于两钳间从脐动脉中采血置于有肝素的注射器中,用Astfup的方法分析其中的气体,再自脐带断端取混合血置于有肝
The aim of this study was to elucidate the effect of intrauterine hypoxia and acidosis on the concentration of cortisol in umbilical cord blood during spontaneous delivery and induction labor.The study included 108 full-term infants who were delivered vaginally at Helsinki State Obstetrical Hospital in 1978 Of which 86 cases of natural childbirth, 22 cases of oxytocin induction labor, all of the fetus during childbirth were monitored by echocardiography, and umbilical cord plasma free cortisol concentration and umbilical arterial blood pH levels were measured .Fetal delivery Immediately after clamping the umbilical cord with two vascular forceps, the blood was collected from the umbilical artery in the clamp between two clamps and placed in a syringe with heparin. Astfup’s method was used to analyze the gas and the mixed blood from the broken end of the umbilical cord was placed in the liver
