Background: Trauma is the second most common cause of death in Thailand, relatively with massive blood loss. Coagulopathy plays a role in blood loss. Differences in mechanisms and organs injured can affect coagulopathy stage and blood loss. Thromboelastometry is a measuring instrument for accurate and rapid detection of coagulopathy. We hypothesized that thromboelastometry in traumatized patients who require surgery in Songklanagarind Hospital will help with early detection of coagulopathy and assess anticipated blood loss. Methods: After approval from the Institutional Ethics Committee, patients aged above 18 years who had American Society of Anesthesiologists Physical Status (ASA) IE–VE, activated by trauma team and sent for emergency surgery. Anesthesia was induced and maintained, and invasive procedures were done as anesthesiologist’s consideration. Thromboelastometry, prothrombin time (PT), partial thromboplastin time (PTT), complete blood count, platelets, arterial blood gas, lactate, and base deficit were assessed and recorded at the emergency room and after Massive Transfusion Protocol (MTP) was activated at 1 and 2 MTP, respectively. Results: Most traumatized patients who were operated on in Songklanagarind Hospital during the study period were male, the most common cause of their injuries was a motorcycle accident, and the most common organ associated with massive blood loss and blood transfusion was the head. After the patients received PRCs of 5 and 11 units, the hematocrit level and platelet count decreased from baseline, while PT and PTT were prolonged. pH, base deficit, and lactate were worse. Clot formation time (CFT), A10, and maximum clot firmness (MCF) of EXTEM were statistically significantly different among the three time periods. Clotting times, CFT, A10, and MCF of INTEM were statistically significantly different among three time periods. A10 and MCF of FIBTEM wer statistically significantly different among three time periods. Conclusion: Most baseline laboratory tests in the traumatized patients who received massive blood transfusion and underwent surgery were worse after they received 1 and 2 MTP. These parameters including thromboelastometry could be guided for preparing proper blood components for patients requiring massive transfusion.
