Electroconvulsive Therapy01:30

Electroconvulsive Therapy

Electroconvulsive therapy (ECT), or shock therapy, remains a critical biomedical intervention for severe, treatment-resistant depression. While its origins can be traced back to Hippocrates' observations that malaria-induced convulsions alleviated mental illness, modern ECT has evolved significantly from its earlier, more primitive applications. First introduced in 1938 by Ugo Cerletti and his colleagues, ECT involves inducing controlled seizures using electrical currents. In its early years,...

Pulmonary Edema II: Pathophysiology

Pulmonary edema is the accumulation of fluid in the interstitial and alveolar spaces of the lungs, impairing gas exchange and oxygen delivery. It may be cardiogenic or noncardiogenic, but both reduce oxygenation and lung compliance.Cardiogenic Pulmonary EdemaCardiogenic edema results from increased hydrostatic pressure in pulmonary capillaries, usually due to left ventricular dysfunction from myocardial infarction, heart failure, or valvular disease. Ineffective cardiac pumping causes blood to...
Cerebral Edema l: Introduction01:19

Cerebral Edema l: Introduction

Cerebral edema is a pathological increase in brain water content that disrupts intracranial pressure regulation and impairs neurological function. Because the cranial vault is rigid, even modest increases in tissue volume can compromise cerebral perfusion, distort neural structures, and initiate secondary injury. Cerebral edema develops through four principal mechanisms: vasogenic, cytotoxic, interstitial, and ionic.Vasogenic EdemaVasogenic edema arises from disruption of the blood–brain...
Cytotoxic Edema: Pathophysiology01:21

Cytotoxic Edema: Pathophysiology

Cytotoxic edema is a form of cerebral edema characterized by intracellular swelling of neurons, astrocytes, and other glial cells. It develops when the mechanisms responsible for maintaining ionic gradients across the cell membrane become impaired. Under normal physiological conditions, the sodium–potassium ATPase actively transports sodium ions out of the cell and potassium ions into the cell, preserving osmotic balance and enabling electrical signaling. This pump requires a continuous supply...
Cerebral Edema ll: Pathophysiology01:22

Cerebral Edema ll: Pathophysiology

Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Summary

Electroconvulsive therapy (ECT) can cause severe hypertension and, rarely, pulmonary edema. This case highlights the importance of monitoring blood pressure and airway during ECT procedures, especially in patients with pre-existing cardiovascular conditions.

Area of Science:

  • Neurology
  • Cardiology
  • Pulmonology

Background:

  • Electroconvulsive therapy (ECT) is a treatment for severe mental health conditions.
  • While generally safe, ECT can have cardiovascular side effects.
  • Pulmonary edema is a rare but serious complication associated with ECT.

Purpose of the Study:

  • To report a rare case of pulmonary edema following electroconvulsive therapy.
  • To discuss potential mechanisms and risk factors for this complication.

Main Methods:

  • A case report of a 42-year-old male patient undergoing right unilateral electroconvulsive therapy.
  • Monitoring of blood pressure and patient's response to anesthesia and ECT.

Main Results:

  • The patient experienced severe hypertension (up to 210/130 mm Hg) and agitation during the eighth ECT treatment.
  • Following the procedure, the patient developed pulmonary edema.
  • Previous treatments were complicated by elevated blood pressure (up to 180/120 mm Hg) and agitation.

Conclusions:

  • Pulmonary edema is an infrequent complication of electroconvulsive therapy.
  • Potential contributing factors include airway obstruction or excessive sympathetic discharge during the procedure.
  • Careful patient monitoring is crucial during ECT, particularly for those with cardiovascular risk factors.
