Objectives: To observe the effect of penetrating-moxibustion therapy on postpartum uterine involution.
Methods: Eighty puerpera were randomized into an observation group and a control group, 40 cases in each one. In the control group, oxytocin injection was administered by intravenous drip, 20 U each time, once daily. In the observation group, on the base of the treatment as the control group, the penetrating-moxibustion therapy was used at Shenque (GV 8), Qihai (CV 6) and Guanyuan (CV 4), 30 min to 40 min each time, twice a day. The intervention of each group started from the first day after childbirth and lasted 3 days. The uterine volume before and after treatment, and in 42 days of postpartum, the height decrease of the fundus of the uterus, the score of visual analogue scale (VAS) for uterine contraction, the volume of lochia rubra in 1 to 3 days of treatment, and lochia duration were compared between the two groups; and the clinical effect was evaluated.
Results: The uterine volume in the observation group was smaller than that of the control group after treatment (P<0.01). In 1 to 3 days of treatment, the height decrease of the fundus of the uterus in the observation group was larger (P<0.01), VAS scores of uterine contraction were lower (P<0.05, P<0.01), the lochia rubra volume was less (P<0.01) than those in the control group. The duration of lochia rubra and lochia was shorter (P<0.01) in the observation group when compared with that of the control group. The favorable rate of uterine involution in the observation group was 95.0% (38/40), higher than that of the control group (75.0%, 30/40, P<0.05).
Conclusions: Penetrating-moxibustion therapy accelerates the recovery of the uterine volume, relieves uterine contraction, shortens the duration of lochia, reduces the lochia volume and promotes the postpartum uterine involution.
目的: 观察透灸法对产后子宫复旧的影响。方法: 将80例产妇随机分为观察组和对照组，每组40例。对照组予缩宫素注射液静脉滴注，每次20 U，每日1次；在对照组治疗基础上，观察组采用透灸法治疗，穴取神阙、气海、关元，每次30~40 min，每日2次。均从产后第1天开始，共治疗3 d。比较两组产妇治疗前后及产后42 d子宫体积、治疗1~3 d子宫底下降高度、治疗1~3 d宫缩痛视觉模拟量表（VAS）评分、治疗1~3 d阴道血性恶露量和恶露持续时间，并评定两组临床疗效。结果: 观察组治疗后子宫体积小于对照组（P<0.01），治疗1~3 d子宫底下降高度均大于对照组（P<0.01），治疗1~3 d宫缩痛 VAS评分均低于对照组（P<0.05，P<0.01），治疗1~3 d阴道血性恶露量均少于对照组（P<0.01），血性恶露及恶露持续时间短于对照组（P<0.01）。观察组子宫复旧良好率为95.0%（38/40），高于对照组的75.0%（30/40，P<0.05）。结论: 透灸法能加速产后子宫体积恢复，缓解宫缩痛，缩短恶露持续时间，减少恶露排出量，促进子宫复旧。.
