ABSTRACT
Objective: We assessed whether inhalation of low dose of nitric oxide comparing with administering 100% oxygen during cardiac catheterization would be as a method to screen patients with congenital heart disease and pulmonary hypertension for operation. Methods: We chose 67 cases of congenital heart disease with pulmonary hypertension undergoing cardiac catheterization. While spontaneously breathing room air (FiO 2, 0 21), the pulmonary artery pressure (PAP) and pulmonary vascular resistance (PVR) were recorded as baseline. Patients continued to breathing 40 ppm nitric oxide with FiO 2 0.30 and 100% oxygen, for 30 minutes. Effects of inhalation of nitric oxide on pulmonary vasculature were studied. Results: Comparing with breathing room air, after inhalation of 100% oxygen or 40 ppm nitric oxide, PAP, PVR and PRV/SVR were decreased significantly. Conclusion: Comparing with administer 100% oxygen, inhalation of nitric oxide is more sensible and reliable predictor in selecting patients with congenital heart disease and pulmonary hypertension for operation.
