Clinicai Research Of Low-Intensity Focused Ultrasound On Promoting Uterine Involution After Caesarean Section

Objectives To study the efficacy and safety of low-intensity focused ultrasound on uterine involution after cesarean section.Methods73cases with uterine-incision delivery were divided into the control group and the experimental group randomly, control group included41cases, and experimental group included32cases. Experimental group were treated by low-intensity focused ultrasound24hours after surgery, ultrasound therapeutic apparatus were put on the maternal bilateral uterine horn and treated for15minutes (30minutes for two uterine horn) every day, for3consecutive days, the control group were spontaneous recovery. Lochia amount and uterine fundus height were measured by clinical methods three days during treatment, The lochia duration within35days was record by telephone follow up.Uterus three diameter at the first day and uterine effusion at the39th day after treatment were detected by B mode ultrasound. The incidence of postpartum hemorrhage and puerperal infection of two groups were recorded also.Safety study:The local feeling and skin conditions were observed during the treatment period Results1.Clinical observation:No significantly difference in the general condition of the two groups (P>0.05). The lochia amount during the3days treatment and lochia duration wthin35days after treatment of the experimental group were significantly less than the control group (P <0.05).The descending degree of uterine fundus of the experimental group was significantly highter than the control group (P<0.05). No postpartum hemorrhage and puerperal infection occurence during the observation period in two groups.2.Ultrasound examination:The uterus diameter of the experimental group at first day after treatment was significantly less than the control group (P<0.05). The incidence of uterine cavity effusion of the experimental group at the thirty-ninth day after treatment was significantly lower than the control group (P<0.05).3. Safety study:No local paresthesia, skin burns and other adverse were observed during treatmentConclusion The Low-intensity focused ultrasound is a effective and safe method to promot uterine contraction...
