Objective To explore the effect of humanistic nursing on uterine artery embolization in the treatment of scar uterine pregnancy and the degree of pain. Methods A total of 60 cases of scar uterine pregnancy patients admitted to the hospital from May 2015 to May 2017 were randomly selected.According to the nursing methods, these patients were divided into humanistic nursing group and basic nursing group, 30 cases of eachgroup.The scores of neonates in the two groups, starting time of breast-feeding, length of hospitalization, nursing satisfaction, degree of pain and occurrence of adverse reactions were statistically analyzed. Results The scores of neonatal care and nursing satisfaction in the humanistic care group were significantly higher than those in the basic care group, and the differences were statistically significant(P<0.05). The duration of breast-feeding and hospitalization in the humanistic nursing group was significantly shorter than that in the basic nursing group, and the differences were statistically significant(P<0.05). The proportion of no pain in humanistic nursing group was 23.30%, which was significantly higher than that in basic nursing group (6.70%), and the difference was statistically significant(P<0.05). The proportion of severe pain in the humanistic care group was 10.00%, which was significantly lower than that in the basic care group (26.70%), and the difference was statistically significant(P<0.05). The incidence of adverse reactions in the humanistic care group was 16.70%, which was lower than that in the basic care group(56.70%), and thd difference was statistically significant(P<0.05). Conclusions Compared with basic nursing, humanistic nursing can effectively improve the effect of uterine artery embolization in the treatment of scar uterine pregnancy and reduce the degree of pain of patients, which is worthy of promotion.
