Behavioral Emergencies
PARAMEDIC PROGRAM
Summer 08
Strange But True
A 28-year old male was brought into
the ER after an attempted suicide. The
man had swallowed several
nitroglycerin pills and a fifth of vodka.
When asked about the bruises about
his head and chest, he said that they
were from him ramming himself into
the wall in an attempt to make the
nitroglycerin explode.

alone
Management





(cont.)
Assess situation
Protect self and others
Summon law enforcement if necessary
If no evidence of immediate danger, then
one EMT responsible for assessing,
treating and communicating with patient

without sirens
The Spectrum
When is it time for patient
restraint?
Restraints

and chest and take full breaths

ambulance

restrained extremity (neurovascular check) every
15 minutes.
Documentation of Restraint
Application

Neurotransmitters
and Behavior
Neurotransmitters: Norepi






Promotes awakening and enhances
dreams
Elevates mood
CNS locations: cortex, medulla,
hypothalamus, limbic system, cerebellum
NorEpi locations outside the CNS
Mania and delusions with overstimulation
Depression with low levels
Neurotransmitters: Dopamine

Stimulates emotional responses

Controls subconscious skeletal movement


CNS locations: cerebral cortex,
hypothalamus and limbic system
Schizophrenia and schizoid symptoms
from amphetamines
Neurotransmitters: Serotonin



Controls sleep, sensory perception, mood
control
Thermal regulation
CNS locations: hypothalamus, limbic system
and cerebellum

Hallucinations with LSD and overstimulation

Depression and anxiety with low levels
Neurotransmitters: GABA

Gamma aminobutyric acid

Depresses mood and emotion

CNS locations: everywhere!

Enhanced by benzodiazepines

Anxiety from low levels of GABA
Neurotransmitters and Drug






Trazadone
Diazepam

Drug Therapies: Antipsychotics

Phenothiazines and their derivatives


Mellaril, Navane, risperidone, thorazine,
stelazine, Prolixin
Dopamine blockade



Will produce a flatter affect
Suppress hallucinations and delusions
Side effects: hypotension, dystonic reactions
Drug Therapies: Lithium


Metallic compound
Slows the elevated use of serotonin,
norepi and dopamine in the synapse


Slows sodium transport into the cell and
reduces nerve transmission
Effective for chronic control of mania

In mania, sodium transport occurs 200%
more than normal!
Drug Therapies: TCA, MAOI

Both work to keep norepinephrine in the
synapse longer



Elevates activity and mood in depression
Anticholinergic effects
Overdose



Initially, massive amounts of norepi released
Lack of reabsorption drops functional norepi levels
dramatically
Systemic effects!
Drug Therapies: SSRI

Keeps serotonin in the synapse

Prozac, Paxil, Zoloft

Overdose symptoms typically limited
Serotonin Syndrome

Medications that work in similar areas as
SSRIs





TCAs and MAOIs
Tramadol (narcotic)
Meprobamate (Sedative-hypnotic)






Presence of specific physical symptoms
A 24 year-old female was seen for manictype symptoms. She had irritability, rapid
speech and distracted conversation. These
symptoms had progressed over a 1-week
period.
She had no history of mental illness or drug
intoxication.
Lab tests revealed a markedly high T4 level
and she was diagnosed with thyrotoxicosis.
A 28 year-old female with a history of
bipolar disorder was experiencing
significant withdrawal and depression.
She was apathetic with a flat affect and
did not seem to interact with things
around her. An hour after admission, she
was lethargic, nonresponsive and
hypotensive.
Lab tests revealed lithium toxicity.
A 20 year-old was talking incoherently,
picking at her clothes and staring into
space. After she was admitted to the
hospital, her level of consciousness
rapidly deteriorated, becoming
disoriented and less responsive. She had
no history of psychiatric disease or drug
use. Her only history was that of herpes
zoster.
After an EEG and lumbar puncture, she
was diagnosed with encephalopathy.
