Potassium chloride solution extravasation injury
Extract:
“A 66-year-old male was admitted to the emergency department for brain trauma. The patient underwent general anesthesia preoperatively. Potassium chloride solution was given by intravenous infusion pump into a peripheral vein in the dorsum of the left hand due to severe hypokalemia of 2.8 mmol/L. The mixture of potassium chloride (10%, 50 mL) and sodium chloride (0.9%, 10 mL) was infused at a rate of 6 mL/h. However, the patient developed purplish swelling along the site of the cannula, which was not noted until half of the infusion was given.”
