Özet

Objective: This prospective observational study designed to determine the correlation between serum copeptin (CPT) quantities measured in patients presenting to the emergency department with multiple traumas and their hemorrhagic shock stage and blood-fluid replacement needs.

Methods: Adult (≥18 years), non-pregnant patients introduced to the emergency department of a university hospital with multiple traumas between September 2023 and September 2024 were analyzed. A prospective observational and analytical study was managed. At first admission, CPT levels were measured. Additionally, the amounts of delivered crystalloids and blood transfusions were listed. Ethics committee approval was obtained, and participants given informed consent.

Results: Serum CPT levels were statistically significantly higher in patients with major trauma. CPT levels increased with the progression of the hemorrhagic shock stage. As the hemorrhagic shock stage increased, the sum of administered crystalloid fluids decreased, while the need for blood product transfusion remarkably increased (p=0.001).

Conclusion: The findings of the study shoewed a correlation between CPT levels and the severity of hemorrhagic shock in patients with trauma. Increased CPT levels in the early phase may designate occult bleeding and assist in risk stratification during trauma management. CPT appears to be a useful laboratory parameter for recognize between hemorrhagic shock stages 1 and 2, as well as between stages 1 and 3. It can contribute to clinical evaluation and help guide the need for blood and blood product monitoring, even in the absence of direct patient observation.
