چکیده
Background: During laparoscopy, insufflation of an inert gas in the peritoneal cavity creates a working space to facilitate surgery. The space should be large enough to facilitate surgery without increasing intra-abdominal pressure (IAP) over a threshold limit (usually 15mm Hg).Objectives: This experimental study was performed to evaluate the effects of increasing in intra-abdominal pressure on internal organs.Materials and Methods: Twenty female mixed breed dogs (20 ± 3 kg, 18 ± 1.2 months) were selected. They were randomly divided to two groups (n = 10). The intra-abdominal pressure was maintained 12 mm Hg and 20 mm Hg during the operation in control group and in test group respectively.Results: Histopathologic evaluations revealed more pathological changes at the kidney of all the dogs in test group in comparison to control group.Conclusions: Our findings revealed that organs that their blood supplies are related to one single or two arteries and their blood drainage are related to one or two veins are more sensitive to increased intra-abdominal pressure.
