[目的]比较阴道与剖宫产分娩后产妇催乳素水平的差异。[方法]选择自2010年2～7月产科收治分娩的102例产妇,其中择期剖宫产产妇53例(剖宫产组),自然分娩产妇49例(阴道分娩组),采用放射免疫分析法,测定其产前、产后24h和72h时血催乳素(PRL)的水平,两组乳汁分泌量的比较,观察其分娩后新生儿的体重及出生4d后两组新生儿体重的变化进行对比分析。[结果]两组产前、产后24h及72h血PRL比较差异无统计学意义(P﹥0.05),两组分娩过程中其PRL均下降,剖宫产组与阴道分娩组比较,降低显著(P﹤0.05);两组乳汁分泌量比较差异无统计学意义(P﹥0.05);剖宫产组和阴道分娩组新生儿出生后4d,剖宫产组新生儿体重下降5.46%,阴道分娩组新生儿体重下降2.72%,差异有统计学意义(P﹤0.05)。[结论]阴道分娩组PRL浓度高、泌乳时间早、泌乳量多,优于剖宫产组。在严格掌握剖宫产指征下,新生儿体重下降趋势较剖宫产低,努力提高产科质量的基础上,保证新生儿母乳的喂养,正确的指导剖宫产产妇的按需哺乳,帮助产妇术后早期活动和增强母乳喂养的信心。
[Objective] To compare the difference of prolactin levels between vagina and cesarean section after delivery. [Methods] A total of 102 maternal women who received delivery from February to July 2010 were selected. Among them, 53 were elective cesarean section (cesarean section) and 49 were spontaneous delivery (vaginal delivery group). Radioimmunoassay (PRL) levels at prenatal and postpartum24h and72h postpartum were measured. The amount of milk secretion was compared between the two groups to observe the change of the weight of the newborn after delivery and the weight of the newborn after 4d . [Results] There was no significant difference in blood PRL between the two groups before and 24 h and 72 h postpartum (P> 0.05). The PRL of both groups during labor was lower than that of the vaginal delivery group <0.05). There was no significant difference in milk secretion between the two groups (P> 0.05). The neonatal birth weight in cesarean section group and vaginal delivery group decreased 5.46% 4 days after birth, neonatal vaginal delivery group Weight decreased 2.72%, the difference was statistically significant (P <0.05). [Conclusion] The vaginal delivery group had higher PRL concentration, earlier lactation time and more lactation volume than cesarean section group. Under strict control of cesarean section indications, neonatal weight loss trend lower than cesarean section, efforts to improve the quality of obstetric, based on the guarantee of neonatal breast feeding, correct guidance of cesarean section on-demand lactation, to help mothers Early postoperative activity and confidence in breastfeeding.
