The diagnosis of peripartum cardiomyopathy should be considered whenever women present with heart failure during the peripartum period. This cardiomyopathy is distinguished by rapid onset, occurrence in the peripartum period, and significant improvement in up to 50% of affected women. The cause and pathogenesis of this dilated cardiomyopathy remain unknown. ⋯ Worsening of heart failure may require management in the ICU with support by vasodilators, inotropes, and ventricular assist devices. Patients with severe ventricular dysfunction are less likely to survive and recover normal cardiac function. Subsequent pregnancies may provoke a recurrence, even in patients who apparently recover.

ReviewAcute lung injury and acute respiratory distress syndrome in pregnancy.
Acute respiratory failure can be the result of a variety of clinical conditions, such as congestive heart failure, pneumonia, pulmonary embolism, exacerbation of obstructive lung diseases, and acute respiratory distress syndrome (ARDS). This article focuses on developments related to acute lung injury and ARDS and reviews epidemiology, pathogenesis and therapeutic advances with an emphasis on the obstetric population. A brief discussion of tocolytic-induced pulmonary edema, preeclampsia, venous air embolism, and aspiration-related ARDS is included. Management of pregnant women with ARDS is outlined.

Sepsis is the leading cause of death in critically ill patients in the United States. Improvements in the critical care management of septic shock have led to a decrease in the mortality rate in the past decade. ⋯ Pregnant women as a group are younger and have fewer comorbid conditions. Though little is known regarding the treatment of sepsis and septic shock in pregnancy, the same principles and treatment modalities discussed in this article should govern the management of pregnant women.

Obstetric anesthesia is considered to be a difficult, high-risk practice that exposes the anesthesiologist to increased medicolegal liability. Anesthetic management of parturient patients is a challenge, as it involves simultaneous care of two lives. The anesthesia practitioner has a duty to provide safe anesthetic care, including effective airway management when providing regional or general anesthesia. The potential need to manipulate the airway is perhaps the leading cause of concern among obstetric anesthesiologists.

Pulmonary embolism is a significant cause of morbidity and mortality during pregnancy and the puerperium. The spectrum of venous thromboembolism is difficult to diagnose. ⋯ Anticoagulation is the mainstay of therapy for deep vein thrombosis and pulmonary embolism. Most of the literature and practice protocols for the treatment of pregnant women are based on data extrapolated from the nonpregnant population, and more research is needed to improve the understanding of the efficacy and safety of testing and therapy in the pregnant population.
