Brief Summary:
Insufficient uterine tone resulting in atony can potentiate hemorrhage and adverse outcomes for the parturient. Oxytocin is the first pharmacologic agent used, followed by methylergonovine, carboprost, and misoprostol. The American Congress of Obstetricians and Gynecologists (ACOG) recommends the sequential use of oxytocin, followed by methylergonovine, carboprost, misoprostol, then surgical intervention for cases of refractory uterine atony. Many studies have examined the effect and dosage of intravenous uterotonics, including oxytocin.
Although there are anecdotal reports of using intravenous bolus or rapid infusion of methylergonovine, no randomized trial has compared efficacy and side effects of these two routes of administration. Investigators hypothesize that intravenous methylergonovine reduces the time to adequate uterine tone (the tone at which the uterus is adequately contracted to prevent atony after delivery of neonate), decreases the total dose of methylergonovine to contract the uterus, and therefore produces fewer side effects of hypertension, nausea, and vomiting. Reducing the time to achieve adequate uterine tone is likely to decrease postpartum hemorrhage.

Detailed Description:
The United States is one of the few modern countries in which maternal peripartum mortality continues to rise. One of the three most important causes of maternal mortality is severe hemorrhage. Controlling postpartum uterine tone remains an important role for the obstetric anesthesiologist. Insufficient uterine tone resulting in atony can potentiate hemorrhage and adverse outcomes for the parturient. Oxytocin is the first pharmacologic agent used, followed by methylergonovine, carboprost, and misoprostol. The American Congress of Obstetricians and Gynecologists (ACOG) recommends the sequential use of oxytocin, followed by methylergonovine, carboprost, misoprostol, then surgical intervention for cases of refractory uterine atony. Many studies have examined the effect and dosage of intravenous uterotonics, including oxytocin.
Methylergonovine maleate is a semi-synthetic ergot alkaloid. Methylergonovine(200 mcg) is administered intramuscularly when oxytocin has been administered but has not contracted the uterus sufficiently. It is not without side effects, however. Due to its vasoconstrictive properties, methylergonovine has been shown to elevate blood pressures and is avoided in preeclamptic patients who may not tolerate abrupt increases in blood pressures.
