The Effect of Different Types of Temporary Abdominal Closure on Intra Abdominal Hypertension.

This is a prospective comparison trial. Patients that will be included in the trial are those that will have operations in which their abdominal closure is temporary, i.e. patients sustaining trauma or septic abdomen. Patients will be grouped according to the method of temporarily abdominal closure (TAC) procedure: 1. Vacuum-assisted closure (VAC) 2. "Bogota bag" (BB), a sterile intravenous bag silo closure. The two methods are currently accepted with no clear cut evidence to prefer one on another. At Soroka Medical Center the decision to choose either of the methods is at the surgeon's discretion. Intra-abdominal pressure will be measured in all patients by the urinary bladder pressure technique at 6 12 24 ant 48 hours post operation. The measurement is a routine procedure done as part of the monitoring processes of critically ill patients in the General Intensive Care Unit (GICU). Patients will be evaluated for the development of acute intra abdominal hypertension with or without abdominal compartment syndrome.
