Abstract
Effects of pneumoperitoneum in rats. The effects of different pneumoperitoneal pressures on kidney and liver functions and on arterial gasometry in rats are provided. A sample of twenty male rats weighing from 350 to 400 grams and distributed into two groups of ten animals was used. Each animal served as experimental control from which blood samples were collected before introducing CO2 into the peritoneal cavity. Samples underwent pressures of 4 and 6 mm Hg during one hour. Results show that increase in intra-abdominal pressure by CO2 in rats causes changes in their arterial gasometry, liver and kidney. However, no liver or kidney lesions during the above mentioned time were reported.
