- W2023248893 abstract "• Tissue depends on perfusion, but tissue oxygenation measurements have been impractical. To develop a method for the clinical evaluation of bowel viability, we studied Po<sub>2</sub>on the bowel surface (Pso<sub>2</sub>). The Pso<sub>2</sub>was assessed on the stomach and intestine of 11 dogs. Normal small-bowel Pso<sub>2</sub>was 44±11 mm Hg (mean ± SD). When bowel vasculature was interrupted Pso<sub>2</sub>rapidly decreased. Reductions in Pso<sub>2</sub>were related to the degree of ischemia produced. Anastomoses were performed on partially devascularized bowel to determine anastomotic viability at various levels of Pso<sub>2</sub>. The Pso<sub>2</sub>. measured just prior to anastomosis predicted viability of the anastomoses at 48 hours. Anastomoses below 30% of predevascularization Pso<sub>2</sub>necrosed. Between 30% and 50%, one third of anastomoses leaked. At Pso<sub>2</sub>values above 50% of initial normal value all anastomoses healed. Surface oximetry allows accurate intraoperative assessment of bowel perfusion. (<i>Arch Surg</i>1984;119:1252-1256)" @default.
