Spontaneous Vaginal Delivery - Article
ABSTRACT: Vaginal delivery is a natural process that usually does not require significant medical intervention. Management guided by current knowledge of the relevant screening tests and normal labor process can greatly increase the probability of an uncomplicated delivery and postpartum course. All women should be screened for group B streptococcus; women who test positive should be treated with antibiotics during labor. Routine human immunodeficiency virus screening of all pregnant women, and treatment with antiretroviral medication for those who test positive, can reduce perinatal transmission of the infection. Once a woman is in labor, management should focus on the goal of delivering a healthy newborn while minimizing discomfort and complications for the mother. In a patient who tests negative for group B streptococcus, delaying admission to the labor ward until she is in active labor decreases the number of possible medical interventions during labor and delivery. Once a patient has been admitted to the hospital, providing her with continuous emotional support can improve delivery outcomes and the birthing experience. Epidural analgesia is effective for pain control and should not be discontinued late in labor to reduce the need for operative vaginal delivery. Epidurals prolong labor, but do not increase the risk of cesarean delivery. Research has shown that labor may not progress as rapidly as historically reported; this should be considered before intervening for dystocia. Routine episiotomy increases morbidity and should be abandoned. Once the infant has been delivered, active management of the third stage of labor decreases the risk of postpartum hemorrhage.

Transcervical Amnioinfusion - Article
ABSTRACT: Amnioinfusion is being used to treat intrapartum problems known to be associated with fetal compromise, including prophylactic treatment of oligohydramnios during labor and after premature rupture of the membranes, treatment of severe variable decelerations during labor and reducing the risk of meconium aspiration during labor in patients with thick meconium fluid. The procedure is considered effective and easy to perform, with the benefits outweighing the risks.
Common Peripartum Emergencies - Article
ABSTRACT: Peripartum 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.
ABSTRACT: Vacuum extractors have replaced forceps for many situations in which assistance is required to achieve vaginal delivery. Compared with metal-cup vacuum extractors, soft-cup devices are easier to use and cause fewer neonatal scalp injuries; however, they detach more frequently. Vacuum extractors can cause neonatal injury. These devices should be employed when indicated, usually for a nonreassuring fetal heart tracing or failure to progress in the second stage of labor. Complications may be minimized if the physician recognizes contraindications to the use of vacuum extraction. Complete documentation is essential.
