Pulmonary collapse and surgical exposure (1 = complete collapse with perfect surgical exposure ranked as excellent; 2 = total collapse, but the lung still had residual air; and 3 = no collapse was achieved, or if there was partial collapse with interference in surgical exposure). Postoperative adverse reactions (0 = without; 1 = with).
