目的:探讨不同分娩方式足月产儿脐血血浆胃动素、血清胃泌素水平,及其对产褥期母婴消化道症状的影响.方法:采用放射免疫法测定了足月妊娠不同分娩方式脐血血浆胃动素及血清胃泌素含量变化.结果:阴道分娩组血浆胃动素水平明显高于剖宫产组( P＜ 0?01),血清胃泌素也有显著差异( P＜ 0?05).结论:为减少产褥期母婴胃肠道症状,多采用阴道分娩,剖宫产儿应早期母乳喂养,对胃动素水平特别低下者建议投以少量胃动力药.“,”Objective: We investigate the levels of motilin and gastrin in different patterns of full term deliveries and to explore their effects on maternoinfantile gastrointestinal systems in puerperal period. Methods: By radioimmunoassay (RIA), we measured the concentration alterations of plasma motilin and serum gastrin from perinatal umbilical blood through different patterns of full term deliveries. Results: Plasma motilin was significantly higher in vaginal delivery group than that in cesarean section group (P<0 01). Levels of serum gastrin were significant different between these two groups (P<0 01). Conclusion: Vaginal delivery could be selected more often for reducing gastroenteric symptoms at puerperal stage. Breast feeding should begin as early as possible especially for neonate underwent cesarean section. Small dosage of gastric kinetic drugs were suggested for those with much lower motilin level.
