HYPOTHESIS: Abdominal computed tomographic (ACT) scans are useful in the evaluation of sepsis of unknown origin in patients with major trauma. DESIGN: Prospective case series of consecutive patients. SETTING: Intensive care unit of level I academic trauma center. PATIENTS: Eighty-five critically injured patients admitted to the intensive care unit in 32 months (6% of all intensive care unit admissions) who developed sepsis of unknown origin. INTERVENTIONS: One hundred sixty-one ACT scans. MAIN OUTCOME MEASURES: Sensitivity and specificity of the ACT scans, number of patients subjected to changes in treatment following an ACT scan. RESULTS: Forty-nine patients (58%) had an intraabdominal focus of infection identified on ACT scan. Penetrating trauma and emergent laparotomy were the only independent factors associated with abnormal findings on ACT scan. The sensitivity and specificity of the test were 97.5% and 61.5%, respectively. Overall, 59 patients (69%) benefited from treatment changes after an ACT scan. CONCLUSION: Abdominal computed tomographic scans reliably identify intra-abdominal foci of infection in patients with major trauma evaluated for sepsis of unknown origin.
