When pain occurs with potassium chloride infusion, it can be alleviated by lowering the fluid concentration, slowing the infusion rate, and changing the infusion site.
Intravenous infusion of potassium chloride is mainly used to replenish potassium ions, to treat hypokalemia or to supplement the physiological requirements of fasting patients.
During intravenous input, potassium ions will act on the lining of blood vessel walls and peripheral nerves, stimulating nerve endings to trigger pain, and when the fluid concentration is too high, the infusion speed is too fast, and the veins for infusion are thin, more obvious local stabbing pain will be triggered.
The potassium ion concentration can be appropriately reduced (potassium concentration should not exceed 3.4g/L), thicker venous vessels can be selected for infusion (such as lower extremity veins or neutral veins), and the speed of infusion can be slowed down (potassium replenishment speed should not exceed 0.75g/hour), by which the occurrence of pain can be reduced or slowed down.
There are strict indications and methods of use for the input of potassium chloride, and the treatment should be rationally standardized under the guidance of professional doctors.
