Abstract: OBJECTIVE To observe the effects of Xinshenghua Granule plus low frequency electric pulse technology on lactation and uterine involution of parturient after cesarean section. METHODS The 168 cases of parturient after cesarean section were randomly divided into the control group(83 cases) and the observation group(85 cases). The control group were treated with low frequency electric pulse technology. The observation group were treated with Xinshenghua granule plus low frequency electric pulse technology. The uterine height, the amount composition, types and duration of lochia, uterine involution were determined. Investigate the clinical efficacy indexes and compare the 24, 48 h milk yield. RESULTS The reduction uterine heigh degree of the observation group was larger than that of the control group. All 5 d hemorrhagic lochia proportion and duration of lochia of the observation group after cesarean section were less than that of the control group. All the size of uterus of the observation group after 5 days and 42 days cesarean section were less than that of the control group. The total effect rate of the observation group was 88.2%. It was significantly higher than that of the control group(71.1%). The 48 h milk yield of the observation group was also higher than that of the control group. Compared the two groups after treatment, all these index exist statistically significant differences between the two groups. CONCLUSION Xinshenghua granule plus low frequency electric pulse technology could promote lactation and uterine involution of parturient after cesarean section, it is worthy of clinic application.
