Text: Inhalation of nitric oxide with milrinone led to (1) the most significant reduction of pulmonary vascular resistance (transpulmonary pressure gradient from 11. 26 + / - 1. 40 mm Hg [baseline] to 7. 93 + / - 0. 90 mm Hg [24-hour use] in group iNO + Mil versus from 11. 10 + / - 1. 38 to 8. 69 + / - 0. 86 mm Hg ; p = 0. 048 in group iNO and from 11. 17 + / - 1. 41 mm Hg to 9. 72 + / - 1. 32 mm Hg ; p < 0. 001 in group Mil) ; (2) the most significant improvement of arterial blood oxygenation (ratio of arterial oxygen partial pressure to inspired fraction of oxygen from 68. 88 + / - 14. 09 to 131. 25 + / - 15. 92 in group iNO + Mil versus from 70. 07 + / -14. 24 to 120. 20 + / - 15. 92 ; p = 0. 047 in group iNO and from 72. 60 + / - 12. 92 to 95. 20 + / - 13. 49 ; p < 0. 001 in group Mil).
