Respiratory repercussion of pneumoperitoneum induced in pigs

Purpose: To study the respiratory repercussion of differents pneumoperitoneum pressions, with carbon dioxide, induced in pigs. Methods: It was used 14 male Landrance-race pigs, weighing between five and seven kiloragram, with 30 a 45 days of age. The sample was iqually divided in Group A (10mmHg of intra-abdominal during 60 minuts) and Group B (15mmHg of intra-abdominal during 60 minuts). After anesthetic induction, the animals were intubed and kept under monitoring the current volume (CV) and oxigen peripheric saturation (SpO2). Results: It not had statistical difference in CV and SpO2 values before, during and after the induction of pneumoperitoneum. Conclusion: Pneumoperitoneum, at the level of 10 to 15mmHg of intra-abdominal pression, did not cause significance alterations on pigs respiratory standart, during the time period studied.
