A randomized control trial comparing use of oxytocin bolus with and without oxytocin infusion in women with cesarean section after extraction of fetus

80 women for emergency cesarean section will be randomized in to two groups after fulfillment of inclusion and exclusion criteria. Group 1 will receive 3 IU oxytocin bolus and group 2 will receive 3 ml of placebo (0.9% normal saline solution), after delivery of fetus and clamping of umbilical cord. All women will receive oxytocin infusion @ 40 mU/min. All women will receive 2 ml (0.5%) bupivacaine intra-thecally in L3-L4. These women will be compared for obstetrical hemorrhage, hemodynamic profile (BP, Pulse rate, Mean arterial pressure), > 20% fall in hematocrit, need for blood transfusion, side effect profile, duration of surgery and need for manual removal of placenta.
