Use Sodium chloride 0.9% is used in isotonic extracellular dehydration, hyponatremia, and also for diluting and dissolving parenterally administered medicinal substances as a basic solution. How to take Isotonic sodium chloride solution for infusions is administered intravenously (usually by drip). The necessary dose can be calculated individually. The infusion rate can be 540 ml/h (180 drops/min); if necessary, the infusion rate can be increased. The dose of sodium chloride solution for children ranges from 20 ml to 100 ml per day per kg of body weight (depending on age and total body weight). It is also necessary to take into account the instructions for use of added preparations. Contraindications Hypersensitivity to sodium chloride, hypernatremia, hyperhydration conditions, threat of pulmonary edema, cerebral edema. Large volumes of sodium chloride should be used with caution in patients with impaired renal excretory function, with hypokalemia. Administration of large amounts of the solution can lead to chloride acidosis, hyperhydration, and increased potassium excretion from the body. Hypertonic solution is not used subcutaneously and intramuscularly.
