Forty-five pregnant women in the first stage of labour presenting with lower back pain were randomized into 2 groups. One group received intracutaneous injections of sterile water in the lumbosacral region, while the other group was given corresponding subcutaneous injections of isotonic saline, regarded as a placebo treatment. In the group that received intracutaneous sterile water injections the mean VAS score was significantly more reduced compared to the placebo group at 10 min (P less than 0.001), 45 min (P less than 0.02), and at 90 min (P less than 0.05) after the treatment. The midwives' blind estimation of the effectiveness of treatment was consistent with the VAS assessment. However, the requirement of pethidine (meperidine) was similar in the 2 groups. The analgesic method presented was found to be an effective treatment against lower back pain during the first stage of labour and it is speculated that the mode of action resembles acupuncture.
45名处于第一产程且伴有下背部疼痛的孕妇被随机分为两组。一组在腰骶部接受皮内注射无菌水，而另一组接受相应的皮下注射等渗盐水，作为安慰剂治疗。在接受皮内无菌水注射的组中，与安慰剂组相比，治疗后10分钟（P<0.001）、45分钟（P<0.02）和90分钟（P<0.05）时，平均视觉模拟评分（VAS）显著降低。助产士对治疗效果的盲法评估与VAS评估一致。然而，两组哌替啶（度冷丁）的需求量相似。所呈现的镇痛方法被发现是第一产程中下背部疼痛的有效治疗方法，据推测其作用方式类似于针灸。
