Electroconvulsive therapy: a guide for family physicians.
Electroconvulsive therapy, which works by creating a generalized seizure, is used most frequently to treat medication-resistant depression. Other indications for electroconvulsive therapy includes severe depression with suicidal ideation, acute mania and severe psychiatric illness with food and fluid refusal. Electroconvulsive therapy may be administered as an inpatient or outpatient procedure. Treatments are usually administered three times a week for six to 12 treatments. Before this therapy is used, a thorough medical and anesthetic history should be obtained, and a complete physical examination, an electrocardiogram and appropriate laboratory studies should be performed to rule out anemia, electrolyte imbalances, and cardiopulmonary and neurologic risk factors. Heart rate and rhythm, oxygenation, blood pressure and, often, the electroencephalogram are monitored continuously while the patient is anesthetized with a short-acting hypnotic agent and a muscle depolarizing agent. After electroconvulsive therapy, antidepressant or lithium therapy significantly reduces the symptom relapse rate.
