[Disorders of acid-alkaline status and electrolyte composition in appendicitis-related peritonitis in a child].

In children with diffuse appendicular peritonitis the disorders of acidic-alkaline state (AAS) and the electrolytes composition (EC) of venous blood were studied. Before the operation in patients with extended peritonitis metabolic and respiratory alkalosis dominated, with general one--metabolic acidosis. In diffuse local peritonitis the conduction of ethiotropic antibacterial therapy and intravenous infusion of 2.5% thiotriazolin solution was effective; in extended peritonitis without concurrent pathology the application of potassium chloride was the method of choice. After the laparostomy conduction with programmed sanation the prolonged therapy using 2.5% thiotriazolin solution in maximal concentration was administered, in patients with general peritonitis and closed abdominal cavity the sittings of hyperbaric oxygenation were applied. Application of proposed differential complex correction of the AAS and EC disorders in conjunction with surgical methods of treatment had permitted to avoid mortality as a complication of appendicular peritonitis in last decade.
