Abstract: Objective To explore the role of music relaxation therapy interventions in improving maternal negative emotions and delivery quality. Methods We retrospectively analyzed 60 cases of maternal clinical data admitted to the First Affiliated Hospital of Harbin Medical University from October,2014 to October,2015.The control group including 30 cases was given a simple relaxation therapy,on the basis of which,the intervention group including 30 cases was given music therapy.We conducted comprehensive evaluation and comparison of HAMA,HAMD score,childbirth,pain rating and pregnancy outcomes as well as maternal satisfaction between these two groups before and after treatment. Results The scores of HAMA and HAMD before intervention in intervention group and control group have no statistical difference(P>0.05).The scores after the intervention have statistical significance(P<0.05);the first and second stage of labor,and the average hospital stays of pregnant women in the intervention group were significantly lower than those in the control group(P<0.05);postpartum hemorrhage in the intervention group was significantly less than that in the control group(P<0.05);and Apgar scores in the intervention group were significantly higher than those in the control group(P<0.05);there were 2 cases of cesarean section,and cesarean section rate was 6.7% in the intervention group;and there were 8 patients underwent cesarean section,with 26.7% cesarean section rate in the control group,which had statistical significance(P<0.05),and postpartum hemorrhage and neonatal asphyxia in the intervention group were significantly lower than those in the control group(P<0.05);pain rating and pregnancy outcomes were better than those in the control group(P<0.05). Conclusion Maternal music therapy combined with relaxation therapy intervention can effectively improve the quality of negative emotions and maternal childbirth,which can be widely popularized in clinical medicine.
