Commonly used methods of replenishing electrolytes in diarrhea include oral intake, gastric tube supplementation, and intravenous infusion.
1. Oral: For patients who are awake and can eat on their own, minor electrolyte loss can be replenished by oral intake, such as hyponatremia can be replenished by oral salt to replenish sodium and chloride ions.
2. Gastric tube: for some patients who cannot eat by mouth, electrolytes can be supplemented by indwelling gastric tube, such as hypokalemia can be supplemented with potassium chloride slow-release tablets through gastric tube.
3. Intravenous infusion: for patients with acute and critical illnesses who lose a lot of electrolytes due to diarrhea and cause obvious symptoms, in order to avoid possible adverse consequences, it is necessary to actively supplement electrolytes, at this time, you can choose peripheral venous infusion, and if necessary, central venous supplementation of electrolytes can be done, for example, patients with severe hypokalemia can be infused with potassium chloride injections through the right internal jugular vein, and so on.
Which method of electrolyte supplementation should be used should be carried out under the guidance of specialized physicians.
