Review Meta Analysis Comparative Study
Sterile water injection for labour pain: a systematic review and meta-analysis of randomised controlled trials.
Up to one-third of labouring women will experience painful 'back labour'. Sterile water injected lateral to the lumbosacral spine is a simple and well-researched approach to this pain. ⋯ We believe that a large RCT should be mounted to validate our findings regarding the impact of sterile water injections on mode of delivery.
