Diagnostic and Prognostic Value of Thrombocytopenia in Severe Burn Injuries.

BACKGROUND AND OBJECTIVES

Burn injuries are the most severe type of trauma, with complex biological consequences associated with high rates of morbidity and mortality. Prompt recognition and management of burn-related complications are imperative for improving the vital and functional prognosis of the patient. Changes in biological parameters can be essential determinants in the prognosis of the burned patient. Thrombocytopenia in critically ill patients is linked to an elevated risk of mortality. We sought to investigate the significance of thrombocytopenia in severely burned patients while considering the limited available data in the literature.

MATERIALS AND METHODS

A two-year retrospective study was conducted on 90 patients with severe burns admitted to our Burn Centre. Demographic data, burn lesion characteristics, and daily total blood counts, including platelet assessment, complications, and mortality, were recorded and analyzed.

RESULTS

Patients with extensive burns in our study had a poor prognosis based on their Abbreviated Burn Severity Index score (ABSI), age, percentage of total body surface area (TBSA) burned, presence of third-degree burns, and inhalation injuries. Regardless of the moment, patients with thrombocytopenia in our study died significantly more frequently. Compared with the survivors, the platelet count was significantly lower at any given time in the non-survivors group. Significant statistical associations between thrombocytopenia and ABSI score, burn surface area, presence of third-degree burns, and inhalation injuries were identified at different timeframes post-burn injury. Sepsis was encountered in one-third of the patients. Thrombocytopenia was more frequent in patients with sepsis who did not survive compared to survivors and did not normalize until the time of death.

CONCLUSIONS

Thrombocytopenia represents an early indicator of severe complications and outcome predictor in severely burned patients. It is correlated with recognized negative prognostic factors and also with sepsis occurrence. Future research efforts should focus on refining early detection parameters and interventions to improve the prognosis of burn patients.
