To study the effect of antenatal breast milk expression at term pregnancy and subsequent effect on postnatal lactation performance.
A sample size of 200 pregnant women who had completed 37 weeks of gestational period was selected. The sample size was divided equally into study (group 1) and control (group 2). The pregnant women in study (group 1) were advised to gently manually express their breasts at least once daily at any time, preferably during bathing. The remaining women constituted the group 2. At the time of delivery, all the mothers were advised to initiate breastfeeding their baby within half an hour of delivery. The time from initiation of lactation to full lactation when no top feed is required was noted. Assessment of sufficient lactation was judged by the objective and subjective criteria.
In the group 1, 89 % of the cases established full lactation within 6 h of delivery, whereas in the group 2 only 72 % of the cases had established full lactation within 6 h. The difference in the group 1 and the group 2 is statistically significant (P < 0.05) with regard to time interval from initiation of lactation to full lactation. Maternal perception of satisfactory lactation was statistically significantly higher in group 1 compared with group 2. In the group 1, 100 % of vaginal delivery (FTND) cases had established full lactation within 6 h compared with 81 % in the group 2. The result is statistically significant (P < 0.10). In the group 1, 80 % of the lower segment cesarean section deliveries established full lactation within 6 h, whereas in the group 2, it was 61 %. The result is statistically significant (P < 0.10). In objective criteria, the post-feed weight gain was higher in the group 1.
Antenatal manual breast milk expression at term shortens the time taken to from initiation to full establishment of lactation, thus significantly improving postnatal lactational performance by early establishment of plentiful milk secretion.
研究足月妊娠时产前挤奶的效果及其对产后泌乳表现的后续影响。
选取200名已完成37周妊娠期的孕妇作为样本。样本被平均分为研究组（第1组）和对照组（第2组）。建议研究组（第1组）的孕妇每天至少手动轻柔挤奶一次，可在任何时间进行，最好是在洗澡时。其余孕妇组成第2组。分娩时，建议所有母亲在分娩后半小时内开始母乳喂养婴儿。记录从开始泌乳到无需额外喂养达到完全泌乳所需的时间。通过客观和主观标准评估乳汁是否充足。
在第1组中，89%的产妇在分娩后6小时内实现了完全泌乳，而在第2组中，只有72%的产妇在6小时内实现了完全泌乳。第1组和第2组在从开始泌乳到完全泌乳的时间间隔方面差异具有统计学意义（P<0.05）。第1组产妇对泌乳满意度的主观感受在统计学上显著高于第2组。在第1组中，100%的阴道分娩（足月正常分娩）产妇在6小时内实现了完全泌乳，而第2组为81%。结果具有统计学意义（P<0.10）。在第1组中，80%的下段剖宫产分娩产妇在6小时内实现了完全泌乳，而在第2组中为61%。结果具有统计学意义（P<0.10）。在客观标准方面，第1组喂养后体重增加更多。
足月时产前手动挤奶可缩短从开始泌乳到完全建立泌乳所需的时间，从而通过早期建立充足的乳汁分泌显著改善产后泌乳表现。
