Background: Abdominal trauma is a leading cause of morbidity and mortality worldwide. Hematologic parameters, including hemoglobin, white blood cell count (WBC), platelet count, prothrombin time (PT), activated partial thromboplastin time (aPTT), and C-reactive protein (CRP), have been shown to correlate with clinical outcomes in trauma patients. This study aims to evaluate the relationship between hematologic findings and clinical outcomes in patients with abdominal trauma, including complications, mortality, and length of hospital stay.

Methods: A descriptive cross-sectional study was conducted at Imam Reza Hospital, Tabriz, with 120 patients diagnosed with abdominal trauma. Blood samples were collected upon admission, and various hematologic parameters were assessed. Patients were grouped according to their clinical outcomes, including mortality, complications (such as infections, organ failure, and need for surgical intervention), and length of hospital stay. Statistical analysis was performed to evaluate the association between hematologic parameters and outcomes.

Results: Lower hemoglobin levels, elevated WBC counts, prolonged PT and aPTT, and high CRP levels were significantly associated with worse clinical outcomes, including increased complications, longer hospital stays, and higher mortality rates. The mean hemoglobin was lower in the complication group (10.2 g/dL) compared to the non-complication group (12.5 g/dL). The WBC count, platelet count, and CRP levels were also significantly higher in the complication group. Elevated PT and aPTT were associated with the need for surgical interventions and prolonged hospital stays.

Conclusion: Hematologic markers, including hemoglobin, WBC count, platelet count, PT, aPTT, and CRP, play a critical role in predicting clinical outcomes in patients with abdominal trauma. These parameters can be used for early risk stratification, guiding clinical decisions and improving patient management. Early identification of abnormal hematologic values can lead to timely interventions, improving the prognosis of trauma patients.
