title: A case report of the use of magnesium sulphate during anaesthesia in a patient who had adrenalectomy for phaeochromocytoma.
abstract: BACKGROUND
  Patients with phaeochromocytoma have haemodynamic instability during adrenalectomy.
  
  
  METHODS
  A case showing major swings of blood pressure during tumour handling.
  
  
  METHODS
  Magnesium sulphate infusion alone failed to prevent severe hypertension.
  
  
  RESULTS
  The patient had to be given phentolamine and sodium nitroprusside to control the severe hypertension.
  
  
  CONCLUSIONS
  The greatest value of magnesium sulphate is in controlling catecholamine release at induction and intubation, and in association with other agents in controlling arrhythmias and hypertension during tumour handling.
