Brugger H, et al. - Investigators evaluated 103 avalanche victims with reversible out-of-hospital cardiac arrest (OHCA) to assess the cut-off values of serum potassium and core temperature at hospital admission for extracorporeal rewarming in this retrospective multicenter study. They found that 61 candidates were rewarmed by extracorporeal life support. Among them, 6 rewarmed patients survived and 55 died. Serum potassium accurately predicted survival for in-hospital triage of avalanche victims admitted with OHCA. With a sensitivity of 100% for survivors, they noted that the combination of the cut-offs 7 mmol/L for serum potassium and 30°C for core temperature achieved the lowest over-triage rate (47%) and the highest positive predictive value (19%).
