Electroconvulsive therapy (ECT) is advised for severe and treatment-resistant mood disorders, including major depressive disorder with psychotic features, severe mania, bipolar depression, and catatonia, as well as in cases of severe suicidality or when medications are contraindicated, such as during pregnancy.[1-5]

  • ECT is highly effective for severe depression, particularly when there is a history of poor response to medication or psychotherapy, and in cases with psychotic features.[3-4][6]

  • It is considered the most rapid and effective treatment for severe mania and bipolar depression, and can be used when there is a risk of mood destabilization or when rapid mood stabilization is necessary.[1][3]

  • ECT may be used as a last resort in pregnant patients with severe mania or depression when the health of the mother or fetus is at risk.[2]

  • It is also indicated for patients with catatonia, severe suicidality, and those who prefer ECT as a treatment method.[1][4]

  • Safety measures include close monitoring during and after the procedure due to potential cardiovascular changes and other complications like transient postictal confusion and memory loss.[4][6]

Additional info

ECT remains a critical option in the management of severe psychiatric conditions, particularly when other treatments have failed or are unsuitable. The procedure involves inducing generalized seizures under anesthesia, which requires careful monitoring and management of potential side effects such as cardiovascular changes and cognitive disturbances. The decision to use ECT should involve a thorough evaluation of the risks and benefits, considering the severity of the condition, previous treatment responses, and individual patient factors, including pregnancy and cardiovascular health. It is essential for healthcare providers to stay informed about the latest guidelines and safety protocols to optimize patient outcomes and minimize risks.

Treatment As a last resort, consider electroconvulsive therapy in patients with severe depression whose physical health or that of the fetus is at serious risk, or in situations in which the patient or fetus cannot wait until medications improve condition. This treatment requires stringent diagnostic and clinical indications If patient is already on long-term treatment: Ensure dose of medication is therapeutic and resolves symptoms and patient is taking medications as prescribed Exclude treatment nonadherence as cause of major depression If patient is taking lithium, ensure serum concentrations are in target range Consider initiating treatment as for medication-naive patients

For acute episodes of mania (with or without coexisting psychotic symptoms), second- or first-generation antipsychotics (e.g., iloperidone)are more rapidly efficacious than mood stabilizers, with doses similar to their use for acute psychosis (seeTable 362-12). For acute treatment of bipolar depression, the evidence-based psychotherapies that are useful for unipolar depression are helpful, but antidepressants may precipitate mania. Therefore, patients in the depressive phase of illness should receive therapeutic doses of a mood stabilizer first, and antidepressant medication should used at the minimum dose for the minimum duration required. Supportive psychotherapy fosters compliance with maintenance treatments and helps patients manage psychosocial stressors, thereby minimizing their impact on precipitating mania or depression.Electroconvulsive therapy is useful for refractory maniaor depression and for patients with relative contraindications to medications, such as pregnancy.

For patients with psychotic depression, the addition of an antipsychotic medication (seeTable 362-12) to an antidepressant is more efficacious than either alone.For postpartum depression (Chapter 221), zuranolone (a neuroactive steroid that modulates gamma butyric acid receptors at 50 mg daily for 14 days) may be the preferred option. For medication-resistant major depression, expert consultation is required.Electroconvulsive therapyis the most effective treatment available and is the preferred approach for the most severe forms of major depression, especially major depression with psychotic features.,A single intravenous dose of ketamine may rapidly reduce severe depressive symptoms within 24hours,and esketamine nasal spray is effective for treatment-resistant depression.Ketamine appears to be as effective as electroconvulsive therapy for treatment-resistant major depression without psychotic features.However, ketamine can lead to a significant increase in symptoms of psychosis in normal volunteers and people with schizophrenia. Optimal management strategies after initial improvement with ketamine or esketamine remain to be determined. Deep brain stimulation is an investigational therapy for otherwise refractory depression. Overall evidence to date offers modest support for the efficacy of repetitive transcranial magnetic stimulation for depression, whereas transcranial direct current stimulation does not appear to be beneficial.Hallucinogenic drugs such as lysergic acid diethylamide (LSD), psilocybin,,and 3,4-methylenedioxymethamphetamine (MDMA) are experimental approaches that should be considered only under supervised conditions.

OBJECTIVE: To familiarize the reader with the role of electroconvulsive therapy (ECT) in current psychiatric medicine. METHOD: We review clinical indications for ECT, patient selection, contemporary ECT practice, maintenance treatment and ECT in major treatment guidelines. RESULTS: ECT is underutilized largely due to persisting stigma and lack of knowledge about modern ECT technique. CONCLUSION: ECT remains a vital treatment for patients with severe mood disorders, psychotic illness and catatonia.

ECT is used for the treatment of severe depression in patients who have had multiple failed trials of psychotherapy and medication. ECT has an 80% response rate, which is better than for medications, works quickly (within 2 to 3 weeks), and is a safe procedure for most individuals. Cardiologists may be asked to assess patient safety for ECT, as it may cause brief but profound hemodynamic changes, including bradycardia (up to frank asystole, which may last for a few seconds), followed by tachycardia and hypertension. These effects usually resolve within 20 minutes. Rare complications include persistent hypertension, arrhythmias, asystole lasting more than 5 seconds, ischemia, and heart failure. Older age and preexisting CVD, including hypertension, coronary artery disease, heart failure, aortic stenosis, atrial fibrillation, and implanted cardiac devices are associated with increased complication rates. Patients undergoing ECT should be monitored throughout the procedure and until stable after the procedure. With appropriate monitoring and management of medications, almost all patients can safely complete treatment. While there are no absolute contraindications to ECT, the procedure should be delayed in patients who are hemodynamically unstable or who have new-onset or uncontrolled arrhythmias or hypertension. In patients with stable CHD and controlled hypertension, medications may be continued through the morning of the procedure. For patients with sustained post-ECT hypertension, antihypertensive therapy should be given after ECT and premedication used on the morning of subsequent ECT sessions; medications shown to be effective for this indication include labetalol, nicardipine, and clonidine. In patients with an implanted pacemaker, the pacemaker should be tested before and after ECT; a magnet should be placed at the patient’s bedside in the event that electrical interference leads to pacemaker inhibition and bradycardia. ECT appears safe in patients with an ICD.
