problem with ECT. ECT remains, indisputably, the
single most efficacious treatment for serious
depression. The problem with ECT has been, and
remains, the need to diminish adverse cognitive

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
Where to start dosing?
RUL BT / BF
1- Female 2- Female
2- Male 3- Male
ajhuri@gmail.com al-Azhar University, May 2012 42
STIMULUS DOSING RULES
Stimulus 1: RUL, Female
Stimulus 2: BT/BF Female, RUL Male
Stimulus 3: BT/BF Male
After 3rd failed stimulus (uncommon):
jump 2 levels for 4th one
Preselected stimulus: calculated dose
◦ Stimulus 3: RUL, Female
◦ Stimulus 4: All others
Dial the device knob: 1 / 2 – 1 × pt age
(poor method with no evidence)

ajhuri@gmail.com al-Azhar University, May 2012 44
The final rules
Titration session : up to 4-5
restimualtions with 20 seconds apart
THERAPEUTIC STIMULUS
INTENSITY is moderately
suprathreshold for next sessions:
◦ 1.5 – 2.5 × ST in BT/BF,
◦ 2.5 – 6 × ST in RUL
Restimulate increasing 50 – 100 % of
the previous stimulus when needed
ajhuri@gmail.com al-Azhar University, May 2012 45
How to manage inadequate
seizure?
MISSED / ABORTIVE:
◦ Check device and connections
◦ Restimulate: 20 sec apart, up to 5 times ( very
rare), vary the duration and frequency, then pulse
width
◦ Hyperventilate: 15 – 20 / min
◦ IV Flumazenil: if pt is on BZD
◦ DC / Taper drugs interfering: eg AEDs
◦ Decrease IV anesthetic dose / switch to less
anticonvulsant one. Consider xanthines:
Caffeine, theophylline, aminophylline.
◦ Space the schedule
◦ Check recent stimulus increase: paradoxical area
of curve

ICU.
◦ Good ventilation
◦ Additional dose of muscle relaxant
◦ Decrease stimulus
◦ Check pt drugs: eg xanthines May 2012

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

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
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

VAGINAL BLEEDING; abdominal pain; and self-limited
uterine contractions.
Without proper preparation, there was also increased
likelihood of ASPIRATION, aortocaval compression,
and respiratory alkalosis.

ECT during pregnancy
Among the 339 cases reviewed:
◦ 25 fetal or neonatal complications, but only 11 of these,
which included two deaths, were likely related to ECT.
◦ 20 maternal complications reported and 18 were likely
related to ECT.
Although there are limited available data in the
literature, it seems that ECT is an effective
treatment for severe mental illness during
pregnancy and that the risks to fetus and mother
are LOW.

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
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.

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
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.

M-ECT
1 / 3-4 wk for 1 y, then re assess.
RUL is preferred at 6 – 7 × ST.
Ambulatory: Outpatient.

ECT the main themes identified are described. While initially portrayed as a dramatic but effective
psychiatric intervention, ECT on film has come to stand for something quite different, representing the
brutal and generally futile attempts of society to control and suppress the individual, gathering along
the way a hackneyed cinematic grammar that emphasizes its inhumane and punitive nature.] UK

Editor's Notes
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
