Bartter syndrome is a rare disorder characterized by reduced sodium chloride 
transport in the distal nephrons of the kidney. Its clinical features are renal 
salt wasting, hypokalemic metabolic alkalosis, elevated renin and aldosterone 
levels with normal or low blood pressure, polyuria, hypercalciuria and 
malnutrition. The pathophysiologic and biochemical changes in these patients 
should be kept in mind when considering anaesthetic management. This case report 
describes our management in a nineteen months old, 3.6 kg weight male child with 
Bartter's syndrome who underwent elective repair of hiatal hernia and 
gastrostomy.
