交感神经-肾上腺活动引起糖原分解和脂肪分解的生理和代谢反应,包括血葡萄糖、甘油和游离脂肪酸升高。过去的研究已证明阵缩可引起胎儿交感神经-肾上腺活动增加而择期剖宫产者则相对减少。但脂肪分解与此活动间有明显变异。本文拟用测定血葡萄糖、甘油等物质浓度来确定胎儿交感神经-肾上腺活动。本文收集至少孕37周的15名阵痛并经阴道分娩者为一组,17名择期剖宫产者为另一组。在胎儿初生瞬间取产母静脉血和脐动、静脉血,测血气张力和血葡萄糖、甘油、儿茶酚胺等物质的浓度。其结果两组酸硷度相似,而正肾上腺素和考的松有显著
Sympathetic-adrenal activity causes the physiological and metabolic responses to glycogenolysis and lipolysis, including elevated blood glucose, glycerol, and free fatty acids. Past studies have shown that contractions can cause fetal sympathectomy - adrenal activity increased elective cesarean section was relatively reduced. However, there is a significant variation between lipolysis and this activity. This article intends to determine the concentration of blood glucose, glycerol and other substances to determine fetal sympathetic - adrenal activity. This article collected at least 37 weeks of pregnancy pain and vaginal delivery were a group of 17 elective cesarean section for the other group. Instant fetus in the fetus from the birth of mother and umbilical cord blood and venous blood, blood gas tension and blood glucose, glycerol, catecholamines and other substances concentration. The results of two groups of similar degree of alkalinity, norepinephrine and testosterone were significant
