Text: Compared with the untreated group, the patients who received surfactant were characterized by better postoperative oxygenation mean PaO2/FiO2 (418. 8 + / -123. 8 vs. 277. 9 + / -165 mm Hg, P = 0. 004), better chest radiograph score, a lower PGD grade (0. 66 vs. 1. 86, P = 0. 005), fewer cases of severe PGD (1 patient vs. 12, P < 0. 05), earlier extubation (by 2. 2 hr ; 95 % CI 1. 1-4. 3 hr, P = 0. 027), shorter intensive care unit stay (by 2. 3 days ; 95 % CI 1. 47-3. 74 days, P = 0. 001), and better vital capacity at 1 month (61 % vs. 50 %, P = 0. 022).
