AbstractPeripartum emergencies occur in patients with no known risk factors. When the well-being of the fetus is in question, the fetal heart rate pattern may offer etiologic clues. Repetitive late decelerations may signify uteroplacental insufficiency, and a sinusoidal pattern may indicate severe fetal distress. Repetitive variable decelerations suggesting umbilical cord compression may be relieved by amnioinfusion. Regardless of the etiology of the nonreassuring fetal heart pattern, measures to improve fetal oxygenation should be attempted while options for delivery are considered. Massive obstetric hemorrhage requires prompt action. Clinical signs, such as painless bleeding, uterine tenderness and nonreassuring fetal heart patterns, may help to differentiate causes of vaginal bleeding that may or may not require emergency cesarean delivery. The causes of postpartum hemorrhage include uterine atony, vaginal or cervical laceration, and retained placenta. The challenge of managing shoulder dystocia is to effect a rapid delivery while avoiding neonatal and maternal morbidity. The McRoberts maneuver has been shown to be the safest and most successful technique for relieving shoulder dystocia. Eclampsia responds best to magnesium sulfate, supportive care and supplemental hydralazine or labetalol as needed for severe hypertension.
