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.
