Corticosteroids: two types: glucocorticoids (cortisol) and mineralocorticoids (aldosterone)

Hyperphosphataemia: renal failure; increased renal resorption (hypoparathyroidism, thyrotoxicosis); cellular injury with release (tumour lysis syndrome, rhabdomyolysis, haemolysis, ischemic gut)
Transoesophageal Echocardiography: allow real time anatomical and physiological assessment of cardiac status; probes (single, bi, omiplane and epivascular)
