Na+[Cl]-, two black dots in each of the four directions around Cl, ***8, representing 8 electrons. Sodium chloride is an ionic compound with the chemical formula NaCl, colorless cubic crystals or fine crystalline powder with a salty taste. Its source is mainly seawater, is the main component of table salt.

Sodium chloride chemical formula is NaCl, melting point 801 ° C, boiling point 1465 ° C, slightly soluble in ethanol, propanol, butane, and butane and butane mutual solubility into a plasma, soluble in water, solubility in water for 35.9 g (room temperature).NaCl dispersed in alcohol can be formed into a colloid, and its solubility in water due to the presence of hydrogen chloride and reduced, almost insoluble in concentrated hydrochloric acid. Odorless and salty, easily deliquescent. Soluble in water, soluble in glycerol, almost insoluble in ether.

Contraindications to sodium chloride injection

Cerebral, renal and cardiac insufficiency and low plasma proteins should be used with caution. Contraindicated in patients with pulmonary edema.

Isotonic saline contains sodium and chloride ions 154mEq, 50% higher than the plasma chloride concentration, for those who already have acidosis, such as the application of large amounts, can cause hyperchloremic acidosis, so sodium bicarbonate-isotonic saline or sodium lactate-isotonic saline can be used.

In the case of static drip, pay attention to aseptic operation, strictly prevent pollution, 24 hours after the opening of the bottle in summer, should not be continued to use, such as the occurrence of infusion reaction, should be promptly checked and symptomatic treatment. Input overdose can cause tissue edema.
