Abstract: Objective To observe the clinical effect of low-intensity ultrasound in promoting uterine involution following
cesarean section. Methods A total of 122 women undergoing cesarean section were randomly selected and divided into
low-intensity ultrasound treatment group (67 cases) and control group (55 cases). The women in the treatment group received
daily low-intensity ultrasound treatment for 30 min 24 h after the delivery for 3 consecutive days, and the control group had
no particular treatments. The descent of the uterine fundus and cessation of lochia was observed in the two groups. Results
The treatment group showed obviously greater descent of the uterine fundus with a higher rate of cessation of vaginal
bleeding than the control group at 30 days postpartum. The ratio of incomplete uterine involution was significantly lower in
the treatment group than in the control group. Conclusion Low-intensity ultrasound is effective in promoting uterine
contraction and uterine involution following cesarean section.
