分娩方式与产后催乳素及泌乳的相关性研究

The Study about the Relativity between Delivery Mode,Lactation and Prolactin

目的探讨不同分娩方式与产后催乳素(PRL)浓度、泌乳始动时间、泌乳量、新生儿体质量的相关性。方法测定阴道分娩组(140例)和剖宫产组(127例)产妇产前及产后24、48h的PRL浓度,泌乳始动时间,产后24、48h泌乳量及出生后72h新生儿体质量。结果①阴道分娩组和剖宫产组产妇,产前PRL浓度间差异无统计学意义(P>0.05);产后24、48h阴道分娩组PRL浓度均高于剖宫产组(P<0.01);②阴道分娩组泌乳始动时间明显早于剖宫产组(P<0.01);产后24、48h阴道分娩组乳汁充足者所占比例明显高于剖宫产组(P<0.01);③新生儿体质量72h下降≤9%的例数,阴道分娩组多于剖宫产组;体质量72h下降≥10%的例数,剖宫产组明显多于阴道分娩组(P<0.01)。结论阴道分娩产妇PRL浓度高、泌乳时间早、泌乳量多、新生儿体质量丢失少,优于剖宫产。

Objective To discuss the relativity of consistence of prolactin after birth ,lactation beginning time, volume of lactation and the weight of newborn children in different delivery mode. Methods Measure the women＇s PRL consistence and lactation beginning time before birth and 24 h ,48 h alter birth ,who have been divided into vaginal delivery group（ 140 samples） and caesarean birth group （ 127 samples）, note the volume of lactation , and the weight of newborn children that 72 h after birth. Results ①There was no statistieal significance of women＇s PRL consistence before birth,between the two group （ P 〉 0.05 ） ; but, the PRL consistence of the vaginal delivery group was higher than the Caesarean birth group both 24h and 48h after birth（P 〈0.01 ）. ②The lactation beginning time of vaginal delivery group was observably earlier than caesarean birth group（ P 〈0.01 ）, and the same as the volume of lactescenee that 24 h and 48 h after birth （ P 〈 0.01 ）. ③The number of newborn child that loss weight≤〈9%/72h in vaginal delivery group is more than that in caesarean birth group, but, the number that loss weight≥10%/72h in caesarean birth group was greater（ P 〈 0.01 ）. Conclusion The woman delivery from vagina has a higher consistence of PRL,lactescence earlier, has more breast milk, and whose baby was often stronger.
