Objective:To observe the clinical effect of Wujia Shenghua capsules(WBC) for promoting postpartum uterine involution. Method: Eighty cases of full-term vaginal delivery postpartum according to the order of admission were divided into two groups: 40 cases of taking WSC (2.4 g bid for 4 days) as the observation group

40 cases without any medication as the control group. Detailed observation for vaginal bleeding diring 5 d postpartum was carried out for the two groups. Postpartum bloody lochia and pain induced by uterine contraction were also observed. Result: In the observation group

postpartum hemorrhage and severe bleeding appeared one case each. Postpartum hemorrhage (5 cases) and severe bleeding (5 cases) showed in the controls. The difference between the two groups was significant (P<0.05). The average postpartum hemorrhage amount in the observation group was (80.51±13.8) mL

and (100.45±20.12) mL in the control group

with significant difference (P<0.05). In observation group

postpartum bloody lochia duration was (2.56±0.60) d

the pain duration induced by contraction was (2.01±0.34) d

while those in the controls were (3.54±0.89) d

and (2.78±0.45) d. The differences were significant (P<0.05). Conclusion: WSC for maternity can shorten the duration of bloody lochia and pain caused by uterine contraction

reduce postpartum hemorrhage

promote postpartum uterine involution. The effect is significant.
