title: Inhaled nitric oxide for primary pulmonary hypertension in pregnancy.
abstract: BACKGROUND
  Primary pulmonary hypertension is a rare and dangerous entity in pregnancy. Previous studies have found a 35-50% maternal mortality rate in the peripartum period. To date, most reports have described treatment of these patients with diuretics, digoxin, and calcium-channel blockers.
  
  
  METHODS
  We describe the successful treatment of a primigravida with severe primary pulmonary hypertension. We used elective intubation before labor, inhaled nitric oxide therapy, and assisted vaginal delivery with epidural anesthesia that resulted in a viable infant and survival of the mother.
  
  
  CONCLUSIONS
  Nitric oxide can be used to successfully treat primary pulmonary hypertension in pregnancy.
