摘要
目的探讨自然分娩产妇围生期口服肠内营养制剂的效果。方法将158例自然分娩的产妇分为对照组(n=49)、经口营养补充(ONS)组(n=59)、产后经口营养补充(P-ONS)组(n=50)。对照组在第一产程和产后均接受常规膳食供给,ONS组在第一产程和产后都给予口服肠内营养制剂干预,P-ONS组在第一产程接受常规膳食供给,仅在产后给予口服肠内营养制剂干预。比较3组产妇产前和产后血红蛋白水平、第一产程时间、产后24 h出血量、产后腹胀率、泌乳充足率。结果3组产妇血红蛋白水平均呈先下降后升高的变化趋势(P<0.05),但产后第3天血红蛋白均未达到产前水平;3组产妇血红蛋白水平差异无统计学意义(P>0.05)。3组产妇的第一产程时间、产后腹胀发生率差异无统计学意义(均P>0.05);ONS组的产后24 h出血量少于对照组和P-ONS组(P<0.05);ONS组和P-ONS组的泌乳充足率均≥70%,其中ONS组泌乳充足率高于对照组(P<0.05)。结论在自然分娩第一产程中和产后合理使用肠内营养制剂可以减少产后出血量,有助于促进产后泌乳。
Objective To investigate the effect of perinatal oral administration of enteral nutrition agent on puerperae undergoing natural labor.Methods Totally 158 puerperae undergoing natural labor were divided into control group(n=49),oral nutrition supplement(ONS)group(n=59)and postpartum oral nutrition supplement(P-ONS)group(n=50).The control group received routine diet supplement and the ONS group received intervention with oral enteral nutrition agent during the first stage of labor and after delivery,while the P-ONS group received routine diet supplement during the first stage of labor and intervention with oral enteral nutrition agent after delivery.The hemoglobin levels before and after delivery,duration of the first stage of labor,blood loss during 24 hours after delivery,incidence of postpartum abdominal distension,and lactation sufficiency rate were compared among the three groups.Results In the three groups,the hemoglobin level of puerperae exhibited a trend from decline to rise(P<0.05),but the level on the 3rd day after delivery was still under the prenatal level;there was no statistically significant difference in hemoglobin level among the three groups(P>0.05).No statistically significant difference was found among the three groups in duration of the first stage of labor or incidence rate of postpartum abdominal distension(all P>0.05);the ONS group yielded less blood loss during 24 hours after delivery than the control group or P-ONS group(P<0.05);the lactation sufficiency rate was 70%or above in the ONS group and P-ONS group,and the ONS group obtained a higher lactation sufficiency rate as compared with the control group(P<0.05).Conclusion The rational use of enteral nutrition agent during the first stage of natural labor and after delivery can reduce the amount of postpartum bleeding and is beneficial to improving postpartum lactation.
