Statistical analysis We used SPSS Selleck CUDC-907 software (v19.0 for Windows, IBM Corporation, USA) for statistical analysis. Normality of distribution was analyzed by Kolmogorov-Smirnov test. Continuous variables with normal distribution and skewed distribution were analyzed using Student’s t test and Mann–Whitney

u test, respectively. Categorical variables were analyzed using chi-square test. Significance was considered as p < 0.05. Results Patient characteristics A total of 150 patients with abdominal trauma were admitted between November SGC-CBP30 2008 and October 2012, of whom 98 met the inclusion

criteria. Thirty-eight this website patients were excluded due to prolonged time interval between injury and ED admission (n = 36), end-staged liver disease (n = 1), and major traumatic brain injury (n = 1), leaving 60 patients for final analysis (Figure 2). Figure 2 Flowchart showing patient inclusion and exclusion. There were 31 patients in the control group and 29 in the goal-directed group. The two groups were comparable in terms of age and gender. The control group and the goal-directed group had similar ISS (14.3 ± 5.7 vs 16.2 ± 8.0, p = 0.28) and abdominal AIS (3.1 ± 0.7 vs 3.1 ± 0.9, p = 0.86). There were, however, more frequent patients with pancreatic injury in the goal-directed group than the control group (44.8% vs 16.1%, p = 0.015). All but 3 patients (2 in the control group and 1 in the goal-directed group) underwent Y-27632 molecular weight emergency operation for control of intra-abdominal bleeding or repair of intra-abdominal organ injury (Table 1).
