    calcium gluconate yhen iv insulin and nss

  11. Ekg exhibits tented T waves across all leads, which is hyperkalemia. Ekg evidence of hyperkalemia requires cardiac membrane stabilisation with iv calcium gluconate other) otherwise there is significant risk of progression to ventricular tachyarythmia /vfib. This should be given together with iv insulin and fluids to treat the hyperkalemia itself pushing the excess potassium from the ecf into the icf compartment. Resistant severe cases of hyperkalemia require removal to total body potassium with resins
