Further study details as provided by Ain Shams University:

Primary Outcome Measures:
  • To assess the efficacy of intravenous infusion of paracetamol in comparison with placebo (sterile water for injection) in labouring women [ Time Frame: Start of medication till end of first stage of labour. Participants will be followed for the duration of labour, an expected average of 8 hours. ]
    By recoding the need for a rescue additional analgesia and measuring the degree of pain relief (Visual analogue score) during the labor process.

Secondary Outcome Measures:
  • To document safety [ Time Frame: Start of medication till delivery and neonatal assesment. Participants will be followed during this duration of labour, an expected average of 10 hours. ]
    By assessing the adverse events recorded during the study either maternal or fetal/neonatal.

  • To correlate with the duration of labor [ Time Frame: Start of medication till end of second stage of labour. Participants will be followed for the duration of labour, an expected average of 9 hours. ]
    The difference between both groups regarding labour duration
