低强度聚焦超声促进子宫复旧的疗效研究

Efficacy and safety of low-intensity focused ultrasound for uterine involution after delivery

目的探讨低强度聚焦超声促进产妇子宫复旧的疗效及使用的安全性。方法选取住院分娩产妇554例,根据分娩方式不同分为剖宫产组200例和阴道分娩组354例;根据是否初产妇分为初产妇组347例和经产妇组207例;根据是否初产妇及分娩方式不同分为初产妇剖宫产组105例、初产妇阴道分娩组242例、经产妇剖宫产组95例和经产妇阴道分娩组112例4组。于分娩后满24h采用低强度聚焦超声在产妇腹壁子宫投影区域进行治疗,治疗时间20in,分别测量各组患者治疗前后宫底高度,治疗时监测生命体征。结果 4组产妇治疗后宫底高度均较治疗前下降,差异均有统计学意义(均P<0.05)。剖宫产组产妇宫底下降指数低于阴道分娩组,两组比较差异有统计学意义(P<0.05)。初产妇组和经产妇组宫底下降指数比较差异无统计学意义(P>0.05)。治疗过程中产妇生命体征稳定。结论低强度聚焦超声治疗对产妇子宫复旧有一定疗效,且安全性良好。

Objective To evaluate the efficacy and safety of low-intensity focused ultrasound for uterine involution after delivery. Methods Five hundred and fifty four puerperas were enrolled in the study. Puerperas were divided into 4 groups: group I (primipara delivered by cesarean section, n=105), group II (primipara with vaginal delivery, n=242), group III(multipara delivered by cesarean section, n=95) and group IV (multipara group with vaginal delivery, n=112). All puerperas received low-intensity focused ultrasound therapy, 20min each time. The height of the fundus uterus was measured before and after the treatment, the vital signs during the treatment period were monitored. Results The height of the fundus uterus after treatment was significantly lower than that before treatment in all groups (all P<0.05). The descending index of fundal height in cesarean section groups (group I, III) was significantly lower than that of vaginal delivery groups (group II, IV)(P<0.05);while there was no significant difference in the descending index of fundal height between the primipara groups (group I, II) and multipara groups(group III, IV)(P>0.05). During the course of treatment, there were no complaints in puerperas, and their vital signs were stable. Conclusion Low-intensity focused ultrasound can effectively and safely promote uterine involution in puerperas after delivery.
