Objective: The primary objective was to evaluate the outcome of Intra–abdominal hypertension on fascial wound dehiscence, secondarily to identify correlation with length of ICU stay.

Methods: This prospective observational study conducted in Kolhapur, included patients who were admitted in ICU for post–operative management after laparotomy. Information and data was collected on demographics, age, pre–operative grade of intra–abdominal pressure, post–operative grade of intra–abdominal pressure and the length of ICU stay.

Results: 50 patients were included, 21 (42%) patients recovered without dehiscence, 22 (44%) patients had fascial wound dehiscence, 4 (8%) patients had burst abdomen, 2 (4%) patients had died during the post–operative period and 1 (2%) patient required Laparostomy. A higher Grade of pre–operative and first 24 hours post–operative Intra–Abdominal Pressure was more likely associated with patients of dehiscence group (P < 0.0001).

Conclusion:   IAH is strongly associated with fascial wound dehiscence. Grades of Intra–Abdominal Pressure can predict length of ICU stay.
