阴道分娩与剖宫产对母儿血清胃泌素水平的影响

Serum Gastrin Concentrations of Mothers and Neonates via Vaginal Delivery and Cesarean Section

目的 探讨经阴道分娩与剖宫产对母血和新生儿脐血胃泌素水平的影响。 方法 采用放射免疫法测定择期剖宫产、阴道分娩的孕妇及产后 3～ 5 d的产妇各 2 0例的血清胃泌素水平。同时测定 2 0例经阴道产儿和 2 2例剖宫产儿的脐血胃泌素水平。 结果 分娩发动后母血清胃泌素水平为 (10 8.2 3± 2 4.39) ng/ L ,较未发动宫缩的足月孕妇血清胃泌素水平 (78.2 8± 31.13) ng/ L升高(P<0 .0 5 ) ;产后 3～ 5 d母血清胃泌素水平为 (143.33± 35 .6 1) ng/ L ,较产前明显升高 (与阴道分娩和剖宫产相比分别为 P<0 .0 5 ;P<0 .0 1)。经阴道产儿脐血胃泌素水平为 (138.37± 2 0 .2 8) ng/ L ,明显高于剖宫产儿脐血胃泌素水平 (10 1.2 3± 18.16 ) ng/ L (P<0 .0 5 )。

Objective To study the serum gastrin levels of mothers and neonates via vaginal delivery and cesarean section. Methods The serum gastrin concentrations of 60 women underwent vaginal delivery and elective cesarean section, and the umbilical serum gastrin concentrations of neonates delivered via vagina (20 cases) and cesarean section (22 cases) were measured by radioimmuno assay. Results The serum gastrin concentrations of women in labor(108.23±24.39) ng/L were significantly higher than that of women during cesarean section( P <0.05). The serum gastrin concentration during 3rd to 5th day of postpartum(143.33±35.61) ng/L was significantly increased than that before delivery ( P<0.05;P<0.01 ). The umbilical serum gastrin level of neonates via vaginal delivery(138.37±20.28) ng/L was significantly higher than that of neonates via cesarean section(101.23±18.16) ng/L( P <0.05). Conclusion Vaginal delivery may be more beneficial to the maturity and improvement of neonatal gastrointestinal function than delivery by cesarean section.
