Abstract/OtherAbstract:
OBJECTIVE: To study the effects on the renal system in a porcine model of intraabdominal hypertension, and to determine the indirect technique of choice for determination of the intraabdominal pressure. MATERIAL AND METHODS: 30 pigs were used divided in two groups according with increased intraabdominal pressure values (20mmHg and 30mmHg). In both groups pressures were registered 8 times, summing up to 3hours, with a CO(2) insufflator. Three different measures of the intraabdominal pressure were taken: a direct transperitoneal measure, using a catheter of Jackson-Pratt connected to a pressure transducer, and two indirect measures, a transvesical by means of a Foley to manometer system, and a transgastric by introducing in the stomach a catheter connected to a pressure monitor with electronic hardware. Mean arterial pressure was calculated, along with the cardiac index, production of urine and serum creatinine. RESULTS: There was a greater correlation between the transvesical and the transperitoneal intraabdominal pressures (R(2)=0,95). Average transgastric intraabdominal pressure was inferior to the transperitoneal indicator in all taken measurements. The average arterial pressure descended in both groups, with earlier significant differences observed at 30mmHg (p<0,020). Urine production was lower at 30mmHg compared with the 20mmHg group (9,63±1,57 versus 3.26 ml±1,73). Serum creatinine increased in both groups being pathological at 30mmHg after 1h 20min, with existing differences between early pressures (p<0,027). CONCLUSIONS: This study revealed marked renal affectation with higher severity at 30mmHg pressures. The transvesical technique showed a greater correlation with the direct measurement technique used, defining this as the method of choice for determination of intraabdominal pressure.
