The changes of intraabdominal pressure in patients with retroperitoneal bleeding]

The linear dependence of the intraabdominal pressure and the volume of retroperitoneal bleeding was revealed in 34 patients with the aortic aneurism rupture. In patients with the blunt abdominal trauma, treated conservatively and laparotomized (each group consisted of 26 patients), the intraabdominal pressure is higher in the operated group during the first day after the operation. The main factors of the intraabdominal hypertension seem to be shock and massive infusion and transfusion therapy.
