SESSION 01 · INTRODUCTION TO ECT

What is Electroconvulsive Therapy?

ECT is a medical treatment in which a brief, controlled electrical stimulus is applied to the scalp – under general anaesthesia and muscle relaxation – to induce a generalised seizure of adequate duration and quality.

The seizure is the treatment

A stimulus that fails to produce an adequate seizure has little or no therapeutic effect.

Always “modified” ECT

Anaesthesia, muscle relaxant, 100% oxygen and full monitoring – no pain, no violent convulsion.

A short procedure

Stimulus lasts up to 8 seconds; the treatment takes about 10 minutes, recovery 30–60 minutes.

Given as a course

Usually 6–12 sessions, 2–3 times per week, adjusted to clinical response.

SESSION 01 · INTRODUCTION TO ECT

The Evolution of ECT

1934

Ladislas Meduna induces therapeutic seizures chemically – camphor, then pentylenetetrazol.

1938

Ugo Cerletti and Lucio Bini give the first electrically induced seizure treatment in Rome.

1940s

ECT spreads worldwide and becomes a mainstay of psychiatric treatment.

1951

Succinylcholine is introduced – muscle relaxation makes “modified ECT” possible.

1958

Right unilateral electrode placement introduced to reduce memory side effects.

1970s–80s

Brief-pulse, constant-current devices with EEG monitoring replace sine-wave machines.

2000s

Ultrabrief pulse, dose titration and evidence-based guidelines (APA 2001, NICE 2003).

2017

India’s Mental Healthcare Act permits ECT only with anaesthesia and muscle relaxants.

SESSION 01 · INTRODUCTION TO ECT

Modified vs Unmodified ECT

Unmodified (Direct) ECT

  • No anaesthesia and no muscle relaxant
  • Full tonic–clonic convulsion
  • Risk of vertebral fractures, dislocations, dental and tongue injury
  • Fear, distress and possible awareness
  • Hypoxia and poor haemodynamic control

PROHIBITED IN INDIA – MHCA 2017, Section 95

vs

Modified ECT

  • Short-acting general anaesthesia
  • Muscle relaxant – no violent movement
  • 100% oxygen and assisted ventilation
  • ECG, SpO₂, BP and EEG monitoring
  • Painless, safe and dignified for the patient

GLOBAL STANDARD OF CARE

At Bharosa, every ECT is performed as modified ECT with an anaesthetist present.

SESSION 01 · INTRODUCTION TO ECT

Why ECT Still Matters: The Evidence

60–80%

response rate in severe major depression – higher than any antidepressant medication

80–90%

response rate in catatonia, including many patients who fail benzodiazepines

~50%

of clozapine-resistant schizophrenia patients respond to ECT augmentation

~2

deaths per 100,000 treatments – comparable to minor procedures under general anaesthesia

Rapid onset

Meaningful improvement is often seen within the first 1–2 weeks (3–6 sessions) – critical when life is at risk from suicide, starvation or catatonia.

Superior to medication

Meta-analyses show real ECT is more effective than both simulated ECT and pharmacotherapy for depression.

SESSION 01 · INTRODUCTION TO ECT

ECT: Myths vs Facts

MYTH

FACT

ECT is painful and frightening, like in the movies.

Patients are asleep under general anaesthesia with muscles relaxed – there is no pain and no violent convulsion.

ECT damages the brain.

Imaging and neuropathology studies show no structural brain damage; MRI studies show increases in hippocampal volume.

ECT permanently erases memory.

Memory effects are mostly temporary; new learning recovers within weeks, though patchy gaps around the treatment period may remain.

ECT is outdated – a last resort only.

It is the most effective acute treatment for severe depression and a first-line option in several urgent situations.

ECT changes personality.

ECT does not alter personality; as illness remits, patients often feel more like themselves again.

SESSION 02 · INDICATIONS & CLINICAL APPLICATIONS

When Is ECT First-Line?

Primary (first-line) use

  • Need for rapid response: high suicide risk, severe food/fluid refusal, inanition, catatonic stupor, exhausting agitation
  • Psychotic depression or severe melancholia
  • Other treatments riskier than ECT: elderly, pregnancy, significant medical illness
  • Previous good response to ECT
  • Patient preference, after informed discussion

Secondary use

  • Treatment resistance: inadequate response to adequate trials of medication
  • Intolerance: unacceptable side effects from pharmacotherapy
  • Deterioration: worsening psychiatric or medical condition despite treatment
  • Relapse after a previously effective ECT course

Framework adapted from the APA Task Force on ECT – the decision always rests on individual risk–benefit assessment.

SESSION 02 · INDICATIONS & CLINICAL APPLICATIONS

Special Populations & Precautions

Pregnancy

  • Can be used in all trimesters with obstetric input
  • Left uterine displacement after ~20 weeks; aspiration prophylaxis
  • Fetal heart monitoring; avoid excessive hyperventilation

Elderly

  • Often excellent response; higher seizure threshold
  • Greater cognitive and cardiac vulnerability
  • Prefer RUL / ultrabrief, twice-weekly; monitor cognition closely

Children & Adolescents

  • Rarely needed; effective in severe mood disorders and catatonia
  • MHCA 2017: informed consent of guardian and prior permission of the Mental Health Review Board

Devices & Medical Illness

  • Pacemaker: generally safe – check function
  • ICD: deactivate before ECT, reactivate after, with continuous monitoring
  • Epilepsy: continue anticonvulsants; diabetes: hold morning insulin/OHA

SESSION 03 · CONTRAINDICATIONS & PRE-ECT ASSESSMENT

Contraindications: Assessing Risk

There are no absolute contraindications to ECT – only conditions that carry substantially higher risk.

Raised intracranial pressure

Space-occupying lesions – ECT transiently raises ICP; risk of herniation. Highest-risk condition.

Unstable cardiac disease

Recent myocardial infarction, unstable angina, decompensated heart failure, severe valvular disease.

Recent stroke or haemorrhage

Recent cerebral infarction or intracerebral bleed – BP surge risks extension or re-bleeding.

Aneurysm / vascular malformation

Lesions liable to rupture with the acute rise in blood pressure during the seizure.

Severe pulmonary disease

Severe COPD, poorly controlled asthma or pneumonia increase anaesthetic risk.

Very high anaesthetic risk

ASA physical status 4–5; phaeochromocytoma (risk of hypertensive crisis).

When the psychiatric illness is itself life-threatening, ECT may still be justified – after optimisation with cardiology, neurology and anaesthesia input.

SESSION 04 · TYPES OF ECT & ELECTRICAL PARAMETERS

Stimulus Parameters: The Electrical Prescription

Current (amplitude)

800–900 mA, constant

Sets electric-field strength and the volume of brain stimulated; fixed on most devices

Pulse width

0.25–2.0 ms

Duration of each pulse – shorter pulses are more efficient

Frequency

20–120 Hz

Number of pulse pairs delivered per second

Train duration

0.5–8 s

How long the pulse train is delivered

Charge (dose)

millicoulombs (mC)

Total stimulus dose – device maximum usually 504 mC (1008 mC on extended-range models)

CALCULATING THE DOSE

Charge (mC) = Current (A) × Pulse width (ms) × 2 × Frequency (Hz) × Duration (s)

Worked example

0.8 A × 1.0 ms × 2 × 60 Hz × 4 s

= 384 mC

Impedance check: constant-current devices adjust voltage to impedance (V = I × R). Check static impedance before every stimulus – high = poor contact; very low = current shunting through gel or sweat.

SESSION 04 · TYPES OF ECT & ELECTRICAL PARAMETERS

Stimulus Dosing Strategies

Empirical dose titration

RECOMMENDED

Session 1: start at a low charge and step up until an adequate seizure occurs – this is the seizure threshold (ST). Then treat at: BT 1.5–2.5 × ST · BF ~1.5 × ST · RUL ~6 × ST.

Age-based formula

PRACTICAL

% of device output ≈ age ÷ 2 for bilateral (“half-age” method), ≈ age for RUL. Quick, but may over- or under-dose because thresholds vary widely.

Fixed dose

LEAST PRECISE

The same (often high) dose for every patient. Simple, but ignores individual thresholds – risk of excess cognitive effects or inadequate seizures.

Seizure thresholds can vary up to 40-fold between patients – titration is the most precise way to dose.

What changes the seizure threshold?

Raises threshold

  • Older age, male sex
  • Bilateral placement (vs RUL)
  • Benzodiazepines, anticonvulsants
  • Propofol, thiopentone
  • Progression of the ECT course

Lowers threshold

  • Hyperventilation (hypocapnia)
  • Etomidate, ketamine
  • Lower anaesthetic dose
  • Flumazenil reversal of benzodiazepines

SESSION 05 · MECHANISM OF ACTION

Mechanism of Action: How Does ECT Work?

Neurotransmitter

Enhances serotonergic, noradrenergic and dopaminergic transmission; increases GABA activity; down-regulates β-adrenergic receptors.

Neuroendocrine

Seizure releases hypothalamic–pituitary hormones (prolactin, ACTH, cortisol, oxytocin, vasopressin); may normalise HPA-axis dysregulation.

Anticonvulsant

Seizure threshold rises across the course (GABA, endogenous opioids). Stronger post-ictal suppression is linked with better response.

Neuroplasticity

Increases BDNF and promotes hippocampal neurogenesis (animal studies); MRI shows increased hippocampal and amygdala volume.

Network “reset”

Modulates connectivity in mood-regulating circuits, e.g. reducing frontal hyperconnectivity seen in depression.

No single mechanism explains ECT fully – its effects are likely multi-level, from molecules to brain networks.

27

28 of 53

SESSION 05 · MECHANISM OF ACTION

How the Therapeutic Seizure Works

STEP 1

The stimulus

Brief electrical pulses depolarise cortical neurons. The dose must be above the patient’s own seizure threshold.

STEP 2

Generalised seizure

Synchronised firing spreads through cortical and deep (thalamic, hypothalamic) circuits, releasing monoamines and neuropeptides.

STEP 3

Active inhibition

GABA, adenosine and endogenous opioids end the seizure; post-ictal EEG suppression follows and the threshold rises.

STEP 4

Cumulative change

Across the course: BDNF release, neurogenesis and synaptic remodelling reset mood-regulating networks.

Why seizure quality matters

The seizure is necessary

Sham ECT – anaesthesia without a seizure – is clearly less effective than real ECT.

…but not sufficient

Low-dose RUL produces seizures yet works poorly; efficacy rises with dose above threshold.

Quality predicts response

Strong post-ictal suppression and a rising threshold across the course are linked to better outcomes.

SESSION 06 · ANAESTHESIA & MUSCLE RELAXATION

Physiological Response to the ECT Stimulus

PHASE 1

Stimulus & early seizure

Parasympathetic (vagal) discharge

  • Bradycardia – occasionally brief asystole
  • Transient hypotension
  • Increased salivation
  • Most marked with sub-convulsive stimuli

PHASE 2

During the seizure

Sympathetic surge (catecholamines)

  • Tachycardia and hypertension
  • Raised myocardial O₂ demand; arrhythmias
  • Raised cerebral blood flow and ICP
  • Raised intraocular and intragastric pressure

PHASE 3

Post-ictal

Return towards baseline

  • Gradual normalisation of HR and BP
  • Late arrhythmias possible
  • Post-ictal confusion or agitation
  • Hypoxia if ventilation is inadequate

Clinical implications

Anticholinergic for bradycardia / asystole

β-blocker for hypertension in cardiac patients

Continuous ECG, SpO₂ and BP monitoring

Oxygenation and airway control throughout

SESSION 06 · ANAESTHESIA & MUSCLE RELAXATION

Why Anaesthesia? The Five Goals

Unconsciousness & amnesia

The patient must never be aware of paralysis or the stimulus – humane, dignified care.

Muscle relaxation

Prevents fractures, dislocations and dental or tongue injury from convulsive movements.

Oxygenation

100% O₂ and hyperventilation protect brain and heart; hypocapnia also improves seizure quality.

Haemodynamic control

Blunts the vagal and sympathetic surges, protecting vulnerable patients.

Rapid recovery

Ultra-short anaesthesia (5–10 min) allows early return to the ward or same-day discharge.

THE IDEAL ECT ANAESTHETIC

Rapid onset

Short duration, quick recovery

Minimal anticonvulsant effect – does not shorten the seizure

Haemodynamic stability

Low incidence of nausea and emergence agitation

Ketamine

Agent

Typical IV dose

Effect on seizure

Key points

Propofol

0.75–1.5 mg/kg

Shortens (dose-dependent)

Smooth induction, blunts BP/HR surge, less nausea; widely used

Thiopentone

2–3 mg/kg

Shortens

Anticonvulsant; risk of arrhythmias and laryngospasm

Methohexital

0.75–1.0 mg/kg

Minimal effect

Historical gold standard; limited availability in India

Etomidate

0.15–0.3 mg/kg

Lengthens

For high thresholds / short seizures; myoclonus, nausea, transient adrenal suppression

Ketamine

0.5–2 mg/kg

Lengthens

Proconvulsant with rapid antidepressant action; ↑ BP/HR, emergence reactions

Combination “ketofol” (ketamine + propofol) can balance haemodynamic stability with better seizure quality. Doses are indicative adult ranges – individualise with the anaesthetist.

SESSION 06 · ANAESTHESIA & MUSCLE RELAXATION

Muscle Relaxants, Anticholinergics & Adjuncts

Muscle relaxants

  • Succinylcholine 0.5–1.0 mg/kg IV – agent of choice; onset ~60 s, lasts 5–10 min; fasciculations may cause myalgia
  • Caution: hyperkalaemia risk (burns, neuromuscular disease, prolonged immobility or catatonia), pseudocholinesterase deficiency, malignant hyperthermia history
  • Rocuronium + sugammadex – alternative when succinylcholine is contraindicated

Anticholinergics

  • Glycopyrrolate 0.2–0.4 mg IV or atropine 0.4–0.6 mg IV
  • Purpose: prevent vagal bradycardia/asystole and reduce secretions
  • Use especially: titration sessions, patients on β-blockers, known bradycardia
  • Glycopyrrolate does not cross the blood–brain barrier – less post-ECT confusion

Adjuncts

  • Esmolol / labetalol – blunt tachycardia and hypertension in cardiac patients (esmolol may shorten seizures slightly)
  • Midazolam / diazepam – prolonged seizures, post-ictal agitation
  • Ondansetron – nausea
  • Paracetamol / NSAIDs – headache and myalgia; pre-treat if recurrent

Seizure Monitoring & Adequacy

Stimulus

Recruitment: polyspikes

Spike-and-slow-wave (~3 Hz)

End

Post-ictal suppression

Motor seizure

≥ 20 s

Observed in a limb isolated from the relaxant by an inflated BP cuff (“cuff method”).

EEG seizure

≥ 25 s

Recorded on the device’s EEG channels; usually outlasts the motor seizure.

Quality markers

Look for

High amplitude · bilateral symmetry · clear slow-wave phase · abrupt end · marked post-ictal suppression · heart-rate surge

Duration alone does not guarantee efficacy – judge seizure quality, not just length.

SESSION 07 · ECT PROCEDURE & MONITORING

Managing Seizure Problems

Missed or short seizure

No seizure, or motor < 20 s / EEG < 25 s

  • No seizure: wait ~20–40 s (delayed onset), then restimulate at a higher dose
  • Short seizure: restimulate at a higher dose after a short interval if clinically indicated
  • Check electrode contact and impedance
  • Hyperventilate; lower anaesthetic dose; review BZDs / anticonvulsants
  • Consider etomidate or ketamine; limit to ~3–4 stimuli per session

Prolonged seizure

EEG or motor seizure > 180 s

  • Terminate with IV benzodiazepine (midazolam, diazepam, lorazepam) or propofol / thiopentone
  • Maintain airway, oxygenation and monitoring
  • Look for causes: theophylline, lithium, low threshold, excessive dose
  • Reduce the dose at the next session

Tardive seizure / non-convulsive status

Seizure recurs after the treatment, or confusion is unusually prolonged

  • Obtain EEG to confirm
  • IV benzodiazepines; antiepileptic if needed
  • Neurology opinion; review medications and dose before the next session

SESSION 07 · ECT PROCEDURE & MONITORING

Planning the Course of ECT

Frequency

2–3 sessions per week (e.g. Mon–Wed–Fri). Thrice-weekly acts faster; twice-weekly has fewer cognitive effects.

Number of sessions

Usually 6–12 (range 4–20) – guided by response, not a fixed number.

Review regularly

Rate severity and cognition every 2–3 sessions; stop at remission or when improvement plateaus over 2 sessions.

Switch if needed

Move RUL → BT if there is little improvement after ~4–6 sessions.

Daily ECT

Only briefly, in emergencies – e.g. malignant catatonia, NMS, severe mania.

Acute (index) course

2–3 per week until remission

Continuation ECT

Up to 6 months after remission – e.g. weekly ×4, fortnightly ×4, then monthly

Maintenance ECT

Beyond 6 months – individualised interval, often every 2–5 weeks

Relapse prevention is essential: without continuation treatment, more than half of patients relapse within 6 months. Start continuation pharmacotherapy or ECT.

SESSION 08 · COMPLICATIONS & POST-ECT CARE

Post-ECT Instructions for Patients & Caregivers

Rest

Rest for the rest of the day. A responsible adult should accompany the patient home.

No driving

No driving, cycling or operating machinery for at least 24 hours – ideally throughout the course.

No major decisions

Postpone important legal, financial or life decisions during the course.

Eating

Start with sips of water, then a light meal once fully awake and able to swallow.

Medicines

Resume medicines as advised. Avoid alcohol and any non-prescribed drugs.

Before next session

Nothing by mouth for ≥ 6 h; wash hair (no oil); remove nail polish and jewellery.

Memory support

Keep a diary; family can gently remind about recent events. Memory usually improves within weeks.

Report immediately

Severe confusion, chest pain, breathlessness, severe headache, fever, a fall or injury.

SESSION 08 · COMPLICATIONS & POST-ECT CARE

Common Short-Term Side Effects

Headache

Common after treatment

Manage: Paracetamol or NSAIDs; pre-treat before the next session if recurrent.

Muscle aches

Linked to succinylcholine fasciculations, mostly after early sessions

Manage: Simple analgesics; optimise relaxant dosing.

Nausea / vomiting

Often anaesthetic-related (e.g. etomidate)

Manage: Ondansetron; review the anaesthetic agent.

Jaw pain / dental injury

Direct stimulation of the masseter – not blocked by the relaxant

Manage: Correctly placed bite block; dental check.

Post-ictal confusion

Minutes to about an hour; more with BT and in the elderly

Manage: Reorient, calm environment; review dose and placement.

Fatigue / drowsiness

Usual on treatment days

Manage: Rest; reassure – resolves the same day.

SESSION 08 · COMPLICATIONS & POST-ECT CARE

Cognitive Effects: What to Expect

Acute confusion

Post-ictal disorientation

Minutes to hours after each session – resolves.

Anterograde amnesia

Difficulty retaining new information

During the course – usually resolves within about 2–4 weeks after the last session.

Retrograde amnesia

Gaps for past events, esp. autobiographical

Mostly recovers over weeks to months; some patchy gaps around the treatment period may persist.

Risk factors

  • Bitemporal placement; sine-wave or wider pulses
  • High dose relative to seizure threshold
  • Thrice-weekly schedule; many sessions
  • Older age; pre-existing cognitive impairment
  • Concurrent lithium or high-dose benzodiazepines

How to minimise

  • RUL placement with ultrabrief pulse
  • Titrated dosing – avoid excessive dose
  • Twice-weekly sessions where possible
  • Good oxygenation; review contributory drugs
  • MMSE / MoCA before, during and after the course

SESSION 08 · COMPLICATIONS & POST-ECT CARE

Serious Complications & Their Management

Complication

Management

Cardiovascular: arrhythmia, bradycardia/asystole, hypertension, ischaemia

Anticholinergic; β-blocker; continuous ECG; cardiology input for high-risk patients

Prolonged seizure (> 180 s)

IV benzodiazepine or propofol/thiopentone; oxygenate; review dose and drugs

Tardive seizure / non-convulsive status

EEG, benzodiazepines, antiepileptics; neurology opinion

Prolonged apnoea

Continue ventilation and sedation until recovery; test pseudocholinesterase (dibucaine number)

Post-ictal delirium / severe agitation

Calm environment, reorientation; IV midazolam or propofol; prophylaxis next session

Aspiration

Strict fasting, suction, lateral position, airway protection

Fracture, dislocation, dental injury

Adequate relaxation, bite block, dental check – rare with modified ECT

Treatment-emergent (hypo)mania

Evaluate; continue ECT or add a mood stabiliser as appropriate

~2

deaths per 100,000 treatments

Comparable to minor procedures under general anaesthesia; most deaths are cardiovascular, in patients with significant medical illness.

KEY TAKEAWAYS

Six things to remember

01

Most effective, fastest-acting

ECT is the most effective acute treatment for severe depression – and safe when done well.

02

The seizure is the treatment

Anaesthesia makes it safe, painless and humane; modified ECT is mandatory in India.

03

No absolute contraindications

Weigh risk against benefit and optimise medical conditions before starting.

04

Dose deliberately

Titrate the dose; RUL ultrabrief to protect cognition, BT when speed matters.

05

Monitor every session

Seizure quality, haemodynamics and cognition – adjust as the course progresses.

06

Plan continuation from day one

Relapse is common without continuation pharmacotherapy or ECT.
