EKG Findings of Hypercalcemia -> Shortened QT, Osborne Waves
Management
Treatment:  Fluids, fluids, fluids —- see how the calcium level is responding before giving Lasix;
Think about the mechanism that is causing the hypercalcemia – if due to increased osteoclastic activity give a bisphosphonate – this will take 1-2 days to work
Calcitonin:  If not responding to fluids – calcitonin works quickly
This patient’s calcium level corrected over the course of a couple days with a total of 6-7 L of fluid and 2 doses of calcitonin.
