| Summary: | Background: Exsanguination is the main cause of death in trauma patients. Early determination that a patient requires an emergency operation is crucial for saving of life. We challenge the defining predictors that guide the intervention or emergency operation for hemorrhage control in severe trauma patients. Aims: The aim of this study was to define the predictors that guide the intervention or emergency operation to resuscitate severe trauma patients. Methods: This study was a retrospective study in trauma patients from Songklanagarind hospital. Data were retrospectively collected from a prospective collection registry that included 131 trauma patients who met the trauma activation criteria at Songklanagarind Hospital from January 2014 to December 2014. Emergency operation or intervention was defined as the procedures needed to improve hemostasis within 4 h. Categorical data were compared. Logistic regression was used to measure the relationship between dependent and one or more independent variables. Results: The study population was 81.7% male. The age range was 31–35 years. The most frequent mechanism was blunt injury (78%). The emergency hemostasis patients had 27 patients (20.6%). The factors relate to an emergency operation or intervention to improve the hemostasis within 4 h were focused assessment with sonography for trauma (FAST)-positive (P < 0.001), male (P = 0.02), Injury Severity Score (ISS) ≥25 (P = 0.013), and penetrating injury (P = 0.016). The preventive factors to an emergency hemostasis were platelet ≥100,000 (P = 0.039) and age ≥50 (P = 0.005). Conclusion: The palate count, FAST, male, age, ISS, and penetrating injury are factors that relate to an emergency operation or intervention within the first 4 h.
