OBJECTIVE: To compare photoplethysmography and Doppler ultrasonography in the prediction of the viability of experimental jejunoileal anastomoses in the presence of arterial (n = 11), venous (n = 11), and mixed arterial and venous (n = 9) segmental ischaemia. DESIGN: Experimental open study. MATERIAL: 31 Mongrel dogs. INTERVENTIONS: Laparotomy, selective devascularisation, and anastomosis. In 20 of the experiments a bolus injection of papaverine was given into the superior mesenteric artery. Second laparotomy on day 15, or earlier if indicated. OUTCOME MEASURES: Correlation between photoplethysmography, Doppler ultrasonography, and macroscopic and histological findings. RESULTS: All non-viable anastomoses had photoplethysmographic wave amplitudes of less than 10% of the control value, with sensitivity and specificity of 100%. Venous volume and maximum venous outflow had a sensitivity of 72% and a specificity of 77%. Doppler ultrasonography had a sensitivity of 100%, but a specificity of only 67%. Papaverine had no effect on photoplethysmographic wave amplitude in these experiments. CONCLUSION: Photoplethysmography is the preferred method of assessing intestinal viability in the presence of ischaemia. |
