are divided into two groups, one group receives morphine intraoperatively, and the other group is control group. Postoperative pain
was assessed at specific time interval using numerical analogue scale. Results: Effect of morphine on pain score at awakening and
after 15 minutes show significant difference otherwise no significant difference in the later 16 hours. Time of recovery is significantly
increased in morphine group. Conclusions: Intraoperative morphine administrated after baby delivery in cesarean section decrease
