On the 14th day, 5.7 mmol/l of blood potassium was measured, hyperkalemia was diagnosed. And 5% glucose injection 250 ml plus 4 U insulin injection was given intravenously for continuous intravenous drip at 3.5 U/h. After administration, 5.4 mmol/l of blood potassium was immediately checked, and 5.0 mmol/l of blood potassium was rechecked at 21:41 p.m. On the 21th day, the patient's blood potassium was 5.4 mmol/L, 5% glucose injection plus 4 units of insulin injection were given for intravenous drip of 3.5 U/h.
