Identification of early coagulation changes associated with survival outcomes post severe burns from multiple perspectives.

Coagulation alterations manifest early after severe burns and are closely linked to mortality outcomes. Nevertheless, the precise characterization of coagulation changes associated with early mortality remains elusive. We examined alterations in indicators linked to mortality outcomes at both the transcriptomic and clinical characteristic levels. At the transcriptomic level, we pinpointed 28 differentially expressed coagulation-related genes (DECRGs) following burn injuries and endeavored to validate their causal relationships through Mendelian randomization. DECRGs tied to survival exhibit a significant association with neutrophil function, wherein the expression of CYP4F2 and P2RX1 serves as robust predictors of fatal outcomes. In terms of clinical indicators, early levels of D-dimer and alterations in serum calcium show a strong correlation with mortality outcomes. Coagulation depletion and fibrinolytic activation, stemming from the hyperactivation of coagulation pathways post-severe burns, are strongly linked to patient mortality. Monitoring these early coagulation markers with predictive value can effectively identify individuals necessitating priority critical care.

Deep digital burns treated with 2 abdominal flaps: case report.

We present the case of a 22-year-old man with third- to fourth-degree flame burns to all fingers of the right hand. After removing the necrotic tissues and amputating the carbonized distal segments of each finger, we covered the injured thumb with a paraumbilical tubular flap and covered the other fingers with an abdominal wall marsupial flap. Fifty days after injury, all the wounds healed, and the remaining fingers were salvaged. Four months after injury, the grip strength and the first web span of the right hand was 23.6 kg and 53°, and the patient could fulfill almost all the activities of daily living.
