Fluid therapy: for intestinal obstruction

Contributor(s): John Dodam, Claire Waters


  • Fluid, electrolyte and acid-base imbalances occur via vomiting and sequestration into the bowel.
  • Prolonged obstruction results in a net secretion of water, sodium and potassium into the intestinal lumen.
  • Severity of water and electrolyte loss is greater the more proximal the obstruction.
  • Obstruction of the proximal duodenum may result in hypochloremia due to loss of chloride in vomitus, and metabolic alkalosis.
  • Obstruction distal to the duodenum may result in loss of bicarbonate and metabolic acidosis.
