Randomized Controlled Trial Comparative Study Clinical TrialIntramuscular opioids for maternal pain relief in labour: a randomised controlled trial comparing pethidine with diamorphine.
To compare the pain relief and side effects of intramuscular pethidine with intramuscular diamorphine in labour. ⋯ Intramuscular diamorphine in labour appears to have some benefits, compared with intramuscular pethidine, but the trial was small and further research, particularly into alternative opioids and long term effects on the infants is still needed.
