Women had been then randomised to obtain both intravenous one thousand mg (1000mg) of Paracetamol (Group A, n=30) or intravenous injection of sterile water (Group B, n=30). Both the groups had been observed and compared for time of onset of analgesia, pain intensity was recorded by using Mc Gills scale before ,one and three hours after drug administration, duration of labour, maternal cardio respiratory parameters, mode of delivery, fetal APGAR scores, neonatal outcome and side effects of drugs. Results: No difference in pain intensity was visible earlier than drug administration. There was significant pain reduction in paracetamol group after 1 and 3 hour of drug administration (p<0.001) when compared to placebo. Total duration of labour from enrolment in study to delivery in the paracetamol group changed was 276 mins (4 hrs36 mins) ± 59.97 minutes and in the placebo group it was 451 minutes (7hrs 31mins) ±82.01 mins suggested that total labour duration was shortened in paracetamol group compared to placebo.
