Aim The aim of this study was to investigate the contribution of non-invasively and rapidly obtained biochemical parameter results to the diagnosis and follow-up of intraabdominal injuries in multitrauma patients. Material and Methods A total of 2604 multitrauma patients who were treated following their referral to our emergency department between January 2009 and January 2012 were retrospectively reviewed. A logistic regression analysis was used in the risk assessment. Results Statistically significant associations between intraabdominal injury and certain biochemical variables measured at the time of the referral were determined. These variables were hemoglobin ≤9.99 g/dL [odds ratio (OR): 6.25, 95% CI: 2.86–13.52, p < 0.0001], serum alanine amino transferase (ALT) ≥ 100 IU/L (OR: 34.45, 95% CI: 21.76–54.54, p < 0.0001), and serum lipase ≥ 61 U/L (OR: 10.44, 95% CI: 6.56–16.49, p < 0.0001). The pretest probability score was determined for each patient by adding the scores that were obtained from each factor. ROC curve analysis was performed to determine the diagnostic value of the pretest probability score for detecting intra-abdominal injury (area = 0.88; p < 0.0001). Conclusion The results of our study demonstrated that biochemical parameters may contribute to the diagnosis and follow-up of intraabdominal injuries in multitrauma patients. In particular, ALT, AST, CK and myoglobin were found to have higher ORs than low hemoglobin. After these parameters are tested in larger scale studies in conjunction with the gold standard multislice abdominal CT, they may be used for establishing scores to evaluate the severity of abdominal injuries.
