The management of digitalis poisoning that has occurred mainly includes stopping the use of digitalis drugs immediately, gastric lavage, use of antiarrhythmic drugs, use of atropine, and hemoperfusion. Immediately stop the use of digitalis drugs, such as digoxin and cediran. In addition to this potassium-excreting diuretics, such as furosemide and glucocorticoids, such as methylprednisolone, need to be discontinued, and antiemetic drugs, such as chlorpromazine, need to be given promptly if the patient is experiencing severe vomiting. If the patient is due to accidental oral intoxication, take gastric lavage as soon as possible, and at the same time oral use of activated charcoal adsorption drugs, and the use of drugs for diarrhea. After digitalis poisoning, if the patient appears tachyarrhythmia, need to take oral potassium salts, or intravenous potassium chloride. Potassium salts should not be used if the patient is anuric, hyperkalemic, or has severe atrioventricular block. Beta-blocker drugs such as propranolol and carvedilol. can be used to treat premature ventricular beats, supraventricular or ventricular tachycardia due to digitalis toxicity. If these methods do not work, it is important to promptly consider treatment with electrical defibrillation or pacing. If the patient has a bradyarrhythmia, atropine should be given orally or by sedation as soon as symptoms such as severe atrioventricular block develop. If medication does not work, a temporary intracardiac pacemaker is quickly used. Usually digitalis has a large volume of distribution in the body, so if hemodialysis is not effective, hemoperfusion therapy can be used instead. Do not use any of the medications mentioned above on your own, and follow your doctor’s instructions for all treatments.
