Currently, electroconvulsive therapy used in clinical practice is modified electroconvulsive therapy, in which anesthetics and muscle relaxants are given prior to energization, so that convulsions do not occur after energization, and complications such as fractures and joint dislocations can be avoided. Common complications include headache, nausea, vomiting, anxiety, reversible memory loss, and generalized muscle aches and pains. Generally, none of these symptoms need to be treated, and joint dislocations and fractures are possible. Patients who are older and treated with drugs with anticholinergic effects are prone to impaired consciousness. Of course, anesthetic accidents, delayed asphyxia, severe cardiac arrhythmias, and death are also possible.
