Abstract： Objective To discuss effective nursing measures for postpartum galactostasis in maternalneonatal unit,in order to increase the breastfeeding rate.Methods 82 cases of primipara galactostasis were randomly divided into two groups:the experimental group (42 cases) and the control group (40 cases).The experimental group received 50％ magnesium sulfate hot-wet dressing for 15 to 20 minutes and then electric breast bump treatment for 20 minutes,while the control group received conventional hot-wet dressing for 15 to 20 minutes and then manual milking for 20 minutes.Two groups' remission of galactostasis and whether the milk can meet the needs of the newborns 24 hours after the treatment was compared.Results Out of the 42 cases in the experimental group,29 cases were cured and 11 had improvements,with the total effective rate of 95.2％.Out of the 40 cases in the control group,13 cases were cured and 15 had improvements,with the total effective rate of 70.0％.The difference was statistically significant (x2 =9.217,P ＜ 0.05).36 out of 42 cases in the experimental group had sufficient maternal breast milk,with the breastfeeding rate of 85.7％,while 21 out of 40 cases in the control group had sufficient maternal breast milk,with the breastfeeding rate of 52.5％.The difference was statistically significant (x2 =10.665,P ＜ 0.05).Conclusions 50％ magnesium sulfate hotwet dressing cooperating with electric breast bump had obvious effect on the primiparas' postpartum galactostasis,and can effectively improve the breasffeeding rate.
