Prognostic Value of Capillary Lactatemia in Potentially Severe Polytrauma Patients

Nowadays, the tools available to assess the severity of a polytrauma patient in the pre-hospital setting (vital parameters, shock index, MGAP score, Vittel criteria) have their limitations and are sometimes subjective. To date, there are no objective, practical and reproducible tools for triaging these patients. Venous lactataemia also appears to be predictive of poor outcome in severe trauma. However, there are no studies in the literature on capillary lactataemia, which would indicate the potential severity of a polytrauma patient in the pre-hospital setting. However, it is an easily performed, risk-free assay, the results of which can be obtained rapidly at the scene of the accident. The aim of this project is to confirm that, like venous lactataemia, capillary lactataemia can be useful in the pre-hospital phase for predicting a patient's poor outcome. Incorporating this assay into the assessment of potentially severe polytrauma patients in the pre-hospital phase could improve the predictive value of clinical and contextual data and thus enable better referral and management of these patients.
