Приложение на лидокаин при лечение на шум в ушите

Лидокаинът и неговите производни имат очевиден инхибиторен ефект върху шума в ушите. В 1937 Лоуи проведе изследване за лечение на шум в ушите чрез интравенозно инжектиране на локални анестетици. Може да се види, че историята на интравенозно инжектиране на локални анестетици при лечението на шум в ушите е по-дълга от историята на лечението на аритмия. Обаче, due to intravenous injection of lidocaine in the treatment of ventricular premature beats, Ventricular tachycardia and even ventricular fibrillation have obvious effects. They are widely used in cardiovascular medicine and emergency rescue, so they are highly valued in internal medicine. In contrast, although the effect of intravenous injection of lidocaine on tinnitus is very obvious, but the duration is short, so it occupies a more inferior position in the field of otology than in internal medicine. Lidocaine intravenous injection can often have magical effects on patients with a history of several years and tinnitus.

There was once a patient suffering from tinnitus. When she was given lidocaine intravenously for the first time, her tinnitus stopped abruptly when the drug was slowly pushed in. After the injection, tears filled her eyes with excitement, revealing the ease, comfort, and gratitude that she had been suffering for years and had been relieved from the desperate situation of being tortured by the noise in the ears. Although her tinnitus gradually reappeared about 15 minutes after the injection, the instant effect encouraged her to treat the disease correctly and cooperate with the doctor. After a course of treatment, the application of music masking therapy, the effect is good, so that tinnitus degree and its upset significantly ease.
