Abstract
BACKGROUND AND AIM OF THE STUDY: Sildenafil and beraprost, as orally available pulmonary vasodilators, are used increasingly to treat pulmonary hypertension (PH). An evaluation was made, in patients with PH undergoing valvular heart surgery, as to whether preoperative combined oral sildenafil and beraprost treatment could induce synergistic and prolonged pulmonary vasodilation, or result in a loss of pulmonary selectivity. METHODS: Fifty patients scheduled for valvular heart surgery with a mean pulmonary arterial pressure (PAP) > 30 mmHg were randomly assigned to receive either 50 mg oral sildenafil + 40 microg beraprost, or a placebo, 15 min before the induction of anesthesia. Hemodynamic variables were measured intraoperatively. RESULTS: The treatment group had a significantly lower systemic vascular resistance index at 60 min after medication. No other significant intergroup differences in hemodynamic variables were observed. In addition, significantly more patients in the treatment group required vasopressor therapy. In both groups, the PAP was significantly reduced by general anesthesia, and almost normalized after valvular heart surgery. CONCLUSION: Preoperative oral sildenafil and beraprost treatment resulted in a loss of pulmonary selectivity, and did not provide any additional pulmonary vasodilation or favorable perioperative hemodynamics in patients with PH undergoing valvular heart surgery.
