In the clinical management of hyperkalemia, there are several aspects: 1. Calcium gluconate can be used to deal with high potassium, mainly calcium gluconate solution can be chosen for intravenous injection, which can play a role in lowering the blood potassium. 2. Insulin can also be used to lower the blood potassium, the purpose is to make the blood potassium transfer from extracellular to intracellular, the clinical choice of insulin added to the glucose solution for intravenous injection. 3. If the condition is serious, sodium bicarbonate solution can also be injected intracardially. Therefore, through the above analysis, hyperkalemia should be dealt with in a timely manner because it often leads to serious heart problems and can even lead to cardiac arrest and induced death. Therefore, hyperkalemia must be taken seriously and should be treated actively under the guidance of a doctor once it is detected.
