Electroconvulsive therapy generally refers to electroconvulsive therapy, which may have side effects such as headache, joint dislocation, bone fracture and prolonged apnea. 1. Headache: The treatment involves passing an electric current through the brain to achieve the phenomenon of loss of consciousness and spasm attacks. Some patients may experience headache, nausea and vomiting after the treatment due to the stimulation of the brain. 2. Dislocation of joints: due to body spasm during electroconvulsive therapy, dislocation of joints may occur, and dislocation of jaw joints is more common. 3. Fracture: If the amplitude of body spasm is large during electroconvulsive therapy, it may also lead to fracture, of which thoracic vertebrae compression fracture is more common. 4. Prolonged apnea: Electroconvulsive therapy may cause blockage of the airway, tongue backward and other phenomena, resulting in prolonged apnea, mostly within 10~30 seconds will return to normal. Once the above side effects occur after electroconvulsive therapy, patients should go to the hospital for examination and cooperate with doctors for treatment. Normally, attention should be paid to the regulation of emotions and avoid overwork.
