Rethinking Calcium Use in Trauma Resuscitation

JEMS Development Editor Mike Brown sits down with Dr. Stacy Shackelford, a coauthor of a new JAMA Network Open paper, to unpack findings about calcium abnormalities in trauma patients. The authors tracked a cohort of 1,270 trauma patients arriving at three level I trauma centers and found that 22% presented with hypocalcemia and 5% with hypercalcemia. Early mortality varied significantly by calcium status: 11.9% among hypocalcemic patients, 4.3% among eucalcemic patients, and 22.8% among hypercalcemic patients. Although hypercalcemia was less common than hypocalcemia, it was associated with substantially worse early mortality, suggesting the need for further research into the underlying mechanisms.
