  2. 2. DEFINITION; • It is the production of a generalized central nervous system seizure produced by means of an electric current.
  3. 3. PRINCIPLE; • It is to exceed the main seizure threshold , which here is accomplished by electric current. • If this threshold is not exceeded the treatment fails.
  4. 4. MODE OF ACTION; • Not well understood. • In animal studies , however , it has been noticed to increase the sensitivity of norepinephrine and serotonin receptors.
  5. 5. INDICATIONS FOR ECT; • 70-85% Effective in treatment of severe depression , particularly when agitation and delusion are present with it. In addition in patients with; with suicidal tendency, delay in treatment is a risk to health, refusal to drink and eat, depressive stupors, antidepressants are cotraindicated/nonresponsive.

  7. 7. METHOD OF ECT; • Anesthesia: given by I/V short acting anesthetic (THIOPENTAL 125-150mg)---for sleep, and a muscle relaxant (SUXAMETHONIUM 30-50mg). • Application of electrodes to brain: BILATERALLY/UNILATERALLY. • Dose: 80V for 100-300ms 4-8times for 3-4wks.
  8. 8. METHOD OF ECT (contd.) • Treatment after ECT: manage patients headache, IMIPRAMINE (Tricylic antidepressant) for few months to decrease relapses.
  9. 9. SIDE EFFECTS; • Transient memory loss depending upon , No. • • • and frequency of ECT, Oxygenation during ECT with anesthesia, Use of LITHIUM with ECT (previously). Headache for few hrs to a day or so. Defects in new learning in few people. Anticipatory anxiety. (GENERALLY THESE SIDE EFFECTS ARE SEEN IN THOSE WITH INEFFECTIVE ECT)
  10. 10. PREVIOUSLY SEEN SIDE EFFECTS; • Before anesthesia was used in ECT; spinal compression fractures were common.
  11. 11. COMPLICATIONS; • In 1/1000 cases cardiovascular or respiratory complications develop. • These complications are preventable if contraindications are kept under consideration , along with care during anesthesia.
  12. 12. CONTRAINDICATIONS; • • • • • Increase intra cranial pressure. Cardiac diseases. Aortic aneurysm. Bronchopulmunary disease. Venous thrombosis.
  13. 13. OBSTACLES; • Poor public understanding. • Lack of acceptance of the technique.
