Caesarean delivery rates and analgesia effectiveness following injections of sterile water for back pain in labour: A multicentre randomised placebo controlled trial

摘要

About a third of women experience severe back pain during labour. Injecting small volumes of intracutaneous sterile water into the lumbar region can be used to relieve this pain, however the procedure is controversial and previous reviews call for high quality trials to establish efficacy. We evaluated the impact on birth outcomes and analgesic effects of sterile water injections.
