Question: Can calcium gluconate be given through a CVAD? The patients requiring it (usually dialysis patients) often have difficult IV access, unstable veins and some sort of CVAD in place. If access of the CVAD for administration of fluids and cardiac arrest meds has already been performed, are we still required to start an IO for the calcium gluconate or can it be requested of the BHP to administer through the CVAD with proper flushing before and after?
