A child had repeated vomiting and developed metabolic alkalosis. The treatment given is –
Ringer lactate
I.V. normal saline and potassium
ORS
I.V. Normal saline
Treatment of metabolic alkalosis due to vomiting or nasogastric suction.

Most children with metabolic alkalosis have one of the chloride responsive etiology (e.g., vomiting).
In these situations, administration of suffieeint sodium chloride and potassium chloride to correct volume deficit is necessary to correct metabolic alkalosis.
Adequate replacement of gastric losses of sodium and potassium in a child with vomiting can minimize or prevent the development of metabolic alkalosis.
With adequate intravascular volume and a normal serum potassium concentration, the kidney is able to excrete the excess bicarbonate within a couple of days.
