分娩初期不少产妇腰骶部疼痛明显,这是因为宫颈和子宫体的神经分布终止于该部皮内,引起的疼痛属牵涉性疼痛。皮内注射灭菌注射用水(蒸馏水)可以减轻尿路结石引起的疼痛,所以在分娩过程中试用此法,并没有对照组进行比较。选择45例第一产程的产妇伴有腰骶部明显疼痛并要求镇痛处理者。用此法治疗前至少3小时未接受任何止痛剂。 In the early stages of labor, many maternal lumbosacral pain is obvious because the distribution of nerves in the cervix and the uterus terminates in the dermis, causing the pain to be an insomnia. Intradermal injection of sterile water for injection (distilled water) can reduce the pain caused by urinary tract stones, so try this method during childbirth and did not compare the control group. Select 45 cases of the first stage of labor with significant lumbosacral pain and require analgesic treatment. With this method at least 3 hours before treatment did not receive any analgesics.
