Experiencia en el manejo quirúrigico del síndrome de compartimento abdominal en el Hosptial Occidente de Kennedy

The abdominal compartment syndrome (ACS) is the result of various physiological alterations produced by an abnormal increase of the intra-abdominal pressure. Some of these patients will undergo a surgical procedure for its management. Methods: This is a retrospective case series of 28 patients with ACS who required surgical treatment at the Hospital Occidente de Kennedy between 1999 and 2003. We assessed retrospectively the behavior of McNelis's equation for prediction of the development of the ACS. Results: The leading cause of ACS in our study was intra-abadominal infection (n=6 21,4%). Time elapsed between diagnosis and surgical decompression was less than 4 hours in 75% (n=21) of the cases. The variables that improved significantly after the surgical decompression were CVP (T: 4,0 p: 0,0001), PIM (T:-2,7; p: 0,004), PIA (T1,8; p:0,034) and Urine Output (T:-2,4; p:0,02). The values of BUN, Creatinine and the cardiovascular instability did not show improvement. The ICU and hospital length of stay were 11 days (SD: 9) and 18 days (SD13) respectively. Global mortality was 67,9% (n=19) and mortality directly attributable to the syndrome was 30% (n=8). The behavior of the McNelis's equation was erratic. Condusions: The demographic characteristics as well as disease processes associated with ACS are consistent with the literature. The association between physiological variables and ACS is heterogeneous between patients. Mortality rates attributable to ACS in our institution are within the range described world-wide. The behavior of the McNelis's equation seems to depend greatly upon fluid balance.
