Resumen: Purpose: To evaluate infrared thermometer (IRT) accuracy compared to standard digital thermometer in measuring kidney temperature during arterial clamping with and without renal cooling. Materials and Methods: 20 pigs weighting 20Kg underwent selective right renal arterial clamping, 10 with (Group 1 - Cold Ischemia with ice slush) and 10 without renal cooling (Group 2 - Warm Ischemia). Arterial clamping was performed without venous clamping. Renal temperature was serially measured following clamping of the main renal artery with the IRT and a digital contact thermometer (DT): immediate after clamping (T0), after 2 (T2), 5 (T5) and 10 minutes (T10). Temperature values were expressed in mean, standard deviation and range for each thermometer. We used the T student test to compare means and considered p < 0.05 to be statistically significant. Results: In Group 1, mean DT surface temperature decrease was 12.6 +/- 4.1 degrees C (5-19 degrees C) while deep DT temperature decrease was 15.8 +/- 1.5 degrees C (15- 18 degrees C). For the IRT, mean temperature decrease was 9.1 +/- 3.8 degrees C (3-14 degrees C). There was no statistically significant difference between thermometers. In Group 2, surface temperature decrease for DT was 2.7 +/- 1.8 \degrees C (0-4 degrees C) and mean deep temperature decrease was 0.5 +/- 1.0 degrees C (0-3 degrees C). For IRT, mean temperature decrease was 3.1 +/- 1.9 degrees C (0-6 degrees C). No statistically significant difference between thermometers was found at any time point. Conclusions: IRT proved to be an accurate non-invasive precise device for renal temperature monitoring during kidney surgery. External ice slush cooling confirmed to be fast and effective at cooling the pig model.
