Abstract:
:Pulmonary hypertension associated with pediatric congenital heart defects is a major cause of postoperative morbidity and death. Sildenafil has been combined with inhaled nitric oxide to treat pulmonary hypertension. We retrospectively studied the pre- and postoperative effects of oral sildenafil as monotherapy in children with pulmonary hypertension who underwent surgery to correct congenital cardiac defects. From September 2005 through November 2009, 38 children with moderate-to-severe pulmonary arterial hypertension (pulmonary arterial/aortic pressure ratio, >0.7) underwent cardiac surgery at our institution. Fifteen patients were given sildenafil (0.35 mg/kg, every 4 hr) orally or through nasogastric tubes 1 week before and 1 week after surgery. Twenty-three patients of comparable medical status were given sildenafil only upon the institution of cardiopulmonary bypass and for 1 week after surgery. Postoperatively, the 15 patients who were given preoperative sildenafil had significantly lower mean pulmonary arterial pressures (25.6 ± 3.1 vs. 30.4 ± 5.7 mmHg; P = 0.005) and pulmonary arterial/aortic pressure ratios (0.35 ± 0.05 vs. 0.42 ± 0.07; P = 0.002) than did the other 23 patients. The preoperative therapy also shortened cardiopulmonary bypass time, mechanical ventilation time, and lengths of intensive care unit and hospital stays. No sildenafil-related hypertensive crises or sequelae occurred. As monotherapy, oral sildenafil in low doses appears to control pulmonary hypertension safely and effectively in children undergoing operations to correct congenital heart defects, particularly when it is given both preoperatively and postoperatively. Further study is warranted.
