[Intraperitoneal pressure in acute small bowel obstruction]
Abstract:
The dynamics of intraperitoneal pressure (IPP) in acute small bowel obstruction was investigated in 50 patients with acute small bowel obstruction (ASBO), 25 men and 25 women aged from 16 through 82 years. The measurements were made in a nasogastral probe. Commissural ASBO was found in 24 (48%) patients, obturation--in 6 (12%), invagination--in 3 (6%) patients. Two groups of patients with high IPP (median 124 mm H2O) and low IPP (median 35 mm H2O) were established. The IPP level over 100 mm H2O, measured at admittance, can be considered an indication to operative treatment. Increased IPP makes the lethality risk of the patient higher. In case of non-complicated course of the postoperative period IPP is not higher than 10 mm H2O by the 2nd day. IPP higher than 30 mm H2O points to the development of intraperitoneal complications.
