Electroconvulsive therapy is increasingly being delivered on an outpatient basis and being
administered to seniors as treatment for depression
ELECTROCONVULSIVE THERAPY
 administration of a muscle relaxant
 ex. Succinylcholine (Anectine),
 minimizes seizure activity, preventing
damage to long bones and cervical
vertebrae
ELECTROCONVULSIVE THERAPY
 The usual course is 6 to 12 treatments given
two to three times per week
 Maintenance ECT once a month may help to
decrease the relapse rate for the client with
recurrent depression
 Usual relief is seen after 2-3 ECTs
ELECTROCONVULSIVE THERAPY
At-risk clients include:
1. Post MI
2. Pregnant women
*The resultant seizure from ECT can cause transient
increases in blood pressure, myocardial oxygen
consumption, heart rate, and intracranial pressure.
Uses of ECT
 Clients with major
depressive and bipolar
depressive disorders
 psychotic symptoms are
present such as delusions of
guilt, somatic delusions, and
delusions of infidelity
Uses of ECT
 Manic clients whose conditions are
resistant to lithium and antipsychotic
medications
 clients who are rapid cyclers (a client with
a bipolar disorder who has many episodes
of mood swings close together)
 Clients with schizophrenia (especially
catatonia), those with schizoaffective
syndromes, and psychotic clients.
Uses of ECT
 When antidepressant medications
have no effect
 When there is a need for a rapid
definitive response, such as when a
client is suicidal or homicidal
 The client is in extreme agitation or
stupor
ECT: Pre-procedure
 Explain the procedure to
the client
 Encourage the client to
discuss feelings, including
myths regarding ECT
 Teach the client and family
what to expect
 Informed consent must be
obtained when voluntary
clients are being treated
ECT: Pre-procedure
 For involuntary clients, when
informed consent cannot be
obtained, permission may be
obtained from the next of kin,
although in some states the
permission for ECT must be
obtained from the court
 NPO after midnight or at least
4-8 hours prior to treatment
ECT: Pre-procedure
 Baseline vital signs are taken
 The client is requested to void
 Hairpins, contact lenses, and
dentures are removed
 Administer preoperative medication
if prescribed; glycopyrrolate
(Robinul) or atropine sulfate may be
prescribed to prevent aspiration and
bradyarrhythmias
ECT: DURING procedure
 The nurse must obtain an IV line
 BP and Vitals taken
 ECG and EEG electrodes are
attached to the body
 SHORT acting anesthetics are
administered: Methohexital,
Thiopental
 Muscle relaxant is administered_
Succinylcholine
ECT: DURING procedure
 Oxygen is given by mask
 Tongue guard may be placed
on the mouth
 110-150 volts of electricity is
delivered for 0.5 to 2 seconds
to initiate a tonic- clonic
seizure, usually lasting for 1-
minute
ECT: POST procedure
 Continue monitoring of vital signs
 Patient is usually brought to the
recovery room where emergency
drugs and equipments are
available
 RE-ORIENT the client when he is
awake
 Provide reassurance that the
amnesia is ONLY temporary
ECT: POST procedure
 The patient is returned to the room
after all vitals are stable
 Mental status examination
 NPO temporarily and introduce foods
once GAG reflex will return
Potential side-effects
 Confusion
 Disorientation
 Short term memory loss- which
may last up to 6 months
 Fractures
 Arrhythmias
