Abstract
Adult respiratory distress syndrome (ARDS) is rarely encountered in association with pregnancy, but with the decline in other causes of maternal death, is an increasingly important cause of mortality in obstetric patients. ARDS may result from a variety of different types of pulmonary injury; uniquely obstetric causes include preeclampsia, amnionitis-endometritis, obstetric hemorrhage, and tocolytic therapy. Crucial management issues include support of maternal oxygenation and cardiac output, myriad interactions between the pulmonary process and its treatment, with maternal and fetal physiology, and decision making regarding delivery. Our review of the literature suggests that, for the patient requiring antepartum intubation for ARDS, except at a very early gestational age or when pyelonephritis or varicella pneumonia is a cause of respiratory compromise, delivery will likely be required for maternal and/or fetal indications, and an early decision for delivery may be beneficial. Postpartum management is similar to treatment of the nonpregnant patient with ARDS, with aggressive attention to potential surgically correctable causes for infection. Maternal mortality rates are affected little by duration of intubation, and therefore prolonged mechanical ventilation is justified and appropriate for mothers with ARDS.
