A randomized comparative study of prophylactic oxytocin versus ergometrine in the third stage of labor

ObjectiveTo compare the effect of prophylactic use of oxytocin and ergometrine in management of the third stage of labor.MethodsA prospective randomized study of 600 women assigned to receive either oxytocin or ergometrine in the third stage of labor. Outcome measures were the predelivery and 48-hour postdelivery hematocrit, duration of the third stage, specific side effects, and incidence of postpartum hemorrhage. Statistical analyses were done using the t test for continuous variables and χ2 test for categorical variables. The level of significance was set at P < 0.05.ResultsThere were no significant differences between the 2 groups in maternal age, gestational age, duration of third stage, birth weights, risk for retained placenta, manual removal of placenta, or need for additional oxytocics. Patients in the ergometrine group were at significant risk for nausea, vomiting, headaches, and elevated blood pressure (P = 0.0001).ConclusionOxytocin is as effective as ergometrine at reducing the incidence of postpartum hemorrhage, but without the undesirable side effects of nausea, vomiting, and elevated blood pressure associated with ergometrine.
