Can potassium chloride be administered intravenously by pump?

Under normal circumstances, potassium chloride should not be administered via intravenous infusion pump. The detailed explanation is as follows:

Potassium chloride is an electrolyte supplement used to correct potassium (K⁺) deficiency in the body. Clinically, it is commonly used to treat hypokalemia caused by various conditions, and can also help manage multiple premature beats and tachyarrhythmias induced by digitalis toxicity. However, intravenous infusion via a pump is currently not recommended because it may cause a rapid increase in serum potassium levels, potentially leading to fatal arrhythmias and endangering the patient's life. Commonly available forms of potassium chloride on the market include tablets, sustained-release tablets, and injection solutions. If the injectable form is required, it must first be diluted with an appropriate solution and then administered via slow intravenous drip. Intravenous infusion allows better control over the rate of drug administration, thus preventing hyperkalemia. However, self-medication is strictly prohibited; treatment should be determined based on the severity of the condition and conducted under the guidance of a qualified physician.

Common adverse reactions of potassium chloride include nausea, vomiting, and abdominal pain. Contraindications include patients with hyperkalemia, significantly reduced urine output, or anuria, who must not use this medication.
