Patients scheduled to undergo laparoscopic upper abdominal surgery under general anesthesia were enrolled. Study recruitment and follow-up are complete.<\/p>\n\n\n\n<p><strong>Interventions<\/strong>&nbsp;&nbsp;Patients were randomized to 1 of the following positions at the end of the operation until leaving the postanesthesia care unit: supine (group S), 15\u00b0 SRP (group F), or 30\u00b0 SRP (group T).<\/p>\n\n\n\n<p><strong>Main Outcomes and Measures<\/strong>&nbsp;&nbsp;The primary outcome was the incidence of postoperative hypoxemia in the postanesthesia care unit. Severe hypoxemia was also evaluated.<\/p>\n\n\n\n<p><strong>Results<\/strong>\u00a0\u00a0Out of 700 patients (364 men [52.0%]; mean [SD] age, 47.8 [11.3] years), 233 were randomized to group S (126 men [54.1%]; mean [SD] age, 48.2 [10.9] years), 233 to group F (122 men [52.4%]; mean [SD] age, 48.1 [10.9] years), and 234 to group T (118 women [50.4%]; mean [SD] age, 47.2 [12.1] years). Postoperative hypoxemia differed significantly among the 3 groups (group S, 109 of 233 [46.8%]; group F, 105 of 233 [45.1%]; group T, 76 of 234 [32.5%];\u00a0<em>P<\/em>\u2009=\u2009.002).
