Secondary Abdominal Compartment Syndrome Following Severe Extremity Injury: Unavoidable Or Unnecessary?
Session IV Poster # 1 SECONDARY ABDOMINAL COMPARTMENT SYNDROME FOLLOWING SEVERE EXTREMITY INJURY: UNAVOIDABLE OR UNNECESSARY? Bryan A Cotton MD, Michael C Madigan BS, Clinton D Kemp MD, J Chad Johnson MD PhD, John A Morris Jr MD*, Vanderbilt University Medical Center, Nashville, TN Introduction: Secondary abdominal compartment syndrome (2ACS) is the development of ACS in the absence of abdominal injury. 2ACS is often viewed as an unavoidable sequela of the large volume crystalloid resuscitation “required” to treat severe shock. We hypothesized that early, aggressive resuscitation techniques place patients with severe extremity injuries at risk for developing 2ACS. Methods: The TRACS database was queried for all patients with extremity AIS of 3 or greater and abdominal AIS of 0 treated at our institution between 01/01/2001-12/31/2005. The study group included those patients who developed 2ACS, while the comparison cohort included those who did not develop 2ACS. Results: 48 patients developed 2 ACS and were compared to 48 randomly sampled patients who had extremity AIS of ? 3 and abdomen AIS of 0. There were no differences between the groups with respect to age, sex, race, or individual AIS scores. However, the 2ACS group had a higher ISS (25.6 vs 21.4, p=0.02), higher OR crystalloid administration (9.9 L vs 2.7 L, p<0.001), and more frequent use of a rapid infuser (12.5% vs 0.0%, p=0.01). 65% of those who developed 2ACS did so within 12 hours of admission. Multiple logistic regression identified pre-hospital and ED crystalloid volume as predictors of 2ACS.
