  • There is no evidence to suggest that the mortality associated with ECT is greater than that associated with minor procedures involving general anesthetics,• There is no evidence to suggest that ECT causes brain damage
  • Immediately post-ECT: acute effects within 24 hours of ECT seizure termination,• Subacute effects: greater than 24 hours to less than two weeks after receiving a course of ECT,• Medium-term effects: two weeks to less than three months after receiving a course of ECT,• Longer-term effects: three months to less than six months after receiving a course ECT,• Long term effects: six months or greater after ECT.
  • Limited evidence from controlled clinical trials suggests that the effects on memory and cognitive function may not last beyond 6 months• Subjective reports of memory loss may be more persistent (> 6 months post-ECT) than findings examining objective measures (up to 6 months)
  • Little evidence exists supporting the long-term effectiveness of ECT
  • These results suggest that ECT is an effective and safe treatment for agitation and aggression in dementia. http://www.ncbi.nlm.nih.gov/pubmed/22143072.1
  • Effects of increasing treatment number on the relationship between stimulus intensity and seizure duration:As shown in Figure 5–1, when the stimulus is barely suprathreshold, increasing stimulus intensity will be associated with a longer seizure duration.However, when the stimulus greatly exceeds seizure threshold, seizure duration can be expected to fall rather than increase. In addition, as the numberof index ECT treatments increases, seizure threshold rises and seizure duration falls, resulting in a shift to the right and downward of the curve depictingthe relationship between stimulus intensity and seizure duration. What this means is that some seizures that appear very brief may actually be associatedwith a higher relative stimulus intensity than longer seizures, particularly toward the end of an index ECT course. In practical terms, if increasing stimulusintensity is seen to lead to a decrease in seizure duration, that effect is evidence that the stimulus was well above seizure threshold.
  • The half-age (HA) method estimates the stimulating dose according to the patient's chronological age, using half this age in “percent of charge” for the Thymatron device or the equivalent in milicoulombs for the MECTA device as starting point at the first session.Our data indicates that in most patients the HA method can be used as a starting point of treatment without concerns of over-stimulation. For the few patients who would not seize at their HA method level, treatment could be performed with restimulation at a higher point.Petrides, 2009 PubMed PMID: 19972637
  • In CORE study: Subsequent treatments were performed at a dose level 50% higher than the ST estimated at treatment 1
  • CORE: Seizure threshold was defined as the lowest stimulation level required to elicit an adequate seizure, defined as at least 25 seconds of EEG duration and at least 20 seconds of motor duration. 
  • The optimal dose of muscle relaxant for ECT reduces muscle contractions without inducing complete paralysis. http://www.ncbi.nlm.nih.gov/pubmed/22092267.1
  • Factors that have been described as lowering butyrylcholinesterase activity are liver disease, advanced age, malnutrition, pregnancy, burns, oral contraceptives, monoamine oxidase inhibitors, echothiophate, cytotoxic drugs, neoplastic disease, anticholinesterase drugs, tetrahydroaminacrine, hexafluorenium, and metoclopramide. The histamine type 2 receptor antagonists have no effect on butyrylcholinesterase activity or the duration of succinylcholine's effect. Bambuterol, a prodrug of terbutaline, produces marked inhibition of butyrylcholinesterase activity and causes prolongation of succinylcholine-induced blockade. The β-blocker esmolol inhibits butyrylcholinesterase but causes only minor prolongation of succinylcholine blockade. Despite all the publications and efforts to identify situations in which normal butyrylcholinesterase enzyme activity may be low, this has not been a major concern in clinical practice because even large decreases in butyrylcholinesterase activity result in only moderate increases in the duration of action of succinylcholine. When butyrylcholinesterase activity is reduced to 20% of normal by severe liver disease, the duration of apnea after the administration of succinylcholine increases from a normal duration of 3 minutes to just 9 minutes. Even when treatment of glaucoma with echothiophate decreased butyrylcholinesterase activity from 49% of control to no activity, the increase in duration of neuromuscular blockade varied from 2 to 14 minutes. In no patient did the total duration of neuromuscular blockade exceed 23 minutes. Millers, 2009

    36. 36. Seizure Threshold (ST) The total amount of electricity necessary to induce a seizure ie CONVULSIVE THRESHOLD. ST variance: up to 50 folds, a lot of factors, strong evidence for age, gender and electrode placement, so NOT a constant measure Therapeutic stimulus is NOT equal to the ST stimulus ajhuri@gmail.com al-Azhar University, May 2012 36

    38. 38. Impedance IMPEDANCE: static (200 – 3000 Ω) and dynamic (120 – 350 Ω). Electrodes, scalp and skull. IMPEDANCE: automatic self-test in MECTA devices ◦ Females > Males ◦ RUL > BT > BF Scalp SHUNTING of current: a lower proportion of current entering the brain. It is a short-circuit So, INVERSE RELATION for constant- current devices between ST and dynamic impedance ajhuri@gmail.com al-Azhar University, May 2012 38

    41. 41. STIMULUS DOSING Why? ◦ Cerebral generalization: more effective ◦ Barely suprathreshold (just above ST): ineffective ◦ Markedly suprathreshold (far beyond ST): hazardous ◦ ST is increasing along index ECT course: fixed dosing is inappropriate EMPERICAL TITRATION: most precise PRE SELECTED (FORMULA-BASED) METHOD: pts do not tolerate titration, eg cardiac, severely suicidal. etc FIXED DOSING: may be a malpractice, esp if randomly assigned. ajhuri@gmail.com al-Azhar University, May 2012 41

    52. 52. ECT Prescribing Three items: electrode placement, schedule and number 2 / wk Vs 3 / wk: same at long term ie ( after 1 wk – 6 m) [More than 6 SR studies] It is not possible to predict reliably how many treatments will be required in a course of ECT. A set course of treatments SHOULD THEREFORE NOT BE PRESCRIBED. RCPsych, 2004 No sign of response: stop after BL 6 sessions Slight or temporary response: continue to BL 12 sessions ajhuri@gmail.com al-Azhar University, May 2012 52
    53. 53. Anesthesia for ECT It is just a type of moderate sedation, NOT a full anesthesia. Adjusted per session. Suitable anesthetic drug: Ultra-brief not long duration, light not deep, weak antiepileptic & painless on injection. Typically: barbiturates. Thiopental is common in Egypt. Anticholinergics / Hyperventilation: are NOT routine. ajhuri@gmail.com al-Azhar University, May 2012 53
    54. 54. Anesthesia for ECT Muscle relaxant: Short-acting to protect airway & decrease / minimize ictal motor activity. Full paralysis is not required in most cases. HYPERKALEMIA is a concern: Pts with catatonia / renal impairment / stroke / burn. Typically: succinylcholine (Suxamethonium): 9 – 13 min for recovery at dose 1 mg / Kg. The elimination half-life of succinylcholine is estimated to be 47 seconds ajhuri@gmail.com al-Azhar University, May 2012 54

Eg: Double depression & Schizoaffective  “Continuation treatment has become the rule in contemporary psychiatric practice”. APA 1993  Abruptly stopping ECT after improving is associated with high relapse rates (≥ 50%) ± C-Pharm, esp in the first 6 ms after an index ECT course.  Prophylactic (Preventive) ECT: Continuation / Maintenance ECT.  A controversial practice, no guidelines, few controlled studies and vague differences.*C-Pharm: Continuation pharmacotherapy ajhuri@gmail.com al-Azhar University, May 2012 81
    82. 82. Assessment after an indexcourse Although psychotropic continuation therapy is the prevailing practice, few studies document the efficacy of such treatment after a course of ECT. APA Task Force 2001 Recurrent illness / Relapse on psychotropics / Intolerance to them: a viable option C-ECT: up to 6 ms, aiming at relapse prevention. M-ECT: more than 6 ms, aiming at recurrence prevention. ajhuri@gmail.com al-Azhar University, May 2012 82

    84. 84. C-ECT Classically: up to 6 m. Abbreviated C-ECT (Tapering): short (1 m), long (2 ms). Try tapering before C-ECT. Most studied in depression: likened to antidepressants. Pt has a disorder known to be an acutely responsive to an index ECT: ± drug resistance. Relapse on drugs = partial resistance. Previously / Currently intolerant to drugs: AE / Medical comorbidities / Poor compliance. Poor response to an index ECT: re evaluate after 10 – 12 sessions. ajhuri@gmail.com al-Azhar University, May 2012 84
    85. 85. C-ECT 2nd time relapse / ECT in 3 ms. Pt is severely ill: Taper / C – ECT, you cannot stop or depend on drugs alone. C-ECT Vs C-Pharmacotherapy: controversial esp in depression. CORE 2010: After improvement of a depressive episode: C-Pharm after Index ECT (TCA ± Lithium), nearly equal to C- ECT. (one of the strongest RCTs) Nortriptyline: the most studied C-Pharm, enhancing ECT response & tolerable in old age. ajhuri@gmail.com al-Azhar University, May 2012 85
    86. 86. C-ECT  Recommendations according to EMORY UNIVERSITY ECT Facility, USA*:  Short- Taper: ◦ 1/wk × 1, 1/10 ds × 1, 1/ 2 wks × 1 Long-Taper: ( 2 × Short-Taper) ie 1/wk × 2, 1/10 ds × 2, 1/ 2 wks × 2 C-ECT: RUL: 1/wk × 4, 1/10 ds × 3, 1/ 2 wks × 4 ms BT/BF: 1/wk × 2, 1/10 ds × 2, 1/ 2 wks × 4 ms Inter treatment intervals may be decreased if pt relapses during spacing / tapering. Drugs: Last 2 wks of tapering*Hands-on training and personal communication in Nov, 2010 ajhuri@gmail.com al-Azhar University, May 2012 86
    87. 87. M-ECT More than 6 ms, against recurrence. Controversial practice: NICE report 2003 questioned its empirical evidence ! While it is stated by the APA & RCPsych as a “viable option” in treatment of selected pts. Almost same indications like C-ECT, or if C- ECT cannot be tapered, “convulsive dependence”. Long practice in: Elderly & Medically ill pts who are intolerable to psychotropics. Best studied in: Depression & Schizophrenia. Again: no guidelines, and few RCTs. ajhuri@gmail.com al-Azhar University, May 2012 87
    88. 88. M-ECT 1 / 3-4 wk for 1 y, then re assess. RUL is preferred at 6 – 7 × ST. Ambulatory: Outpatient. ajhuri@gmail.com al-Azhar University, May 2012 88

From review of the 22 currently available films that directly refer to ECT the main themes identified are described.
