Arterial oxygen tensions (PaO 2) fall from standing levels (approximately 100 mm Hg) to 60–80 mm Hg within 5 min of the induction of lateral recumbency and fall even further if dorsal recumbency is employed.1,5 Hypoventilation con-tributes to the decreases in arterial oxygenation, but Preoperative NSAID administration is indicated to minimize pain and inflammation. Remove the hemostats and check again for bleeding. Vatinoxan did not consistently affect lung cytology or blood inflammatory markers.
