title: The pharmacological effect of sodium phosphate after absorption from the peritoneal cavity.
abstract: Hyperosmolar solutions are frequently used in clinical practice for enemas. In a review of the literature we found 43 published cases of severe complications connected with the use of hyperosmolar enemas. The absorption of sodium phosphate led to a raise of the temperature up to 41.1 degrees C, massive acidosis and electrolyte disturbances with hypocalcemia and hypernatremia. The clinical picture was dominated in most of the cases by somnolence or coma. In our experiment the absorption of sodium phosphate from the peritoneal cavity of rats led to similar clinical symptoms and--depending on the amount of sodium phosphate absorbed--to the death of the animals. Hypovolemia, hypernatremia, hypocalcemia and a direct toxic effect of phosphate on the kidneys is responsible for the complex mode of intoxication. Sodium phosphate solutions should not be used in patients with inflammatory bowel disease with a high risk of laceration of the mucosa or perforation of the bowel.
