Psychiatric Emergencies in the
Pediatric Emergency Department

Emergency Medicine

Atlanta
Scope of the Problem
US Dept of Health and Human Services
1 in 10 children in USA (4 million) suffers from a
mental illness
Only 20% will receive needed care
• Psychotherapy recommended for < 50% of patients
evaluated for suicide attempt in the ED with even fewer
actually complying with referral
World Health Organization
By 2020 childhood neuropsychiatric disorders
will be 1 of the top 5 causes of morbidity,
mortality and disability among youth worldwide
Scope of the Problem
Overall ED use increasing, same seen for psychiatric
concerns
1993 to 1999 (Sills and Bland)
1.6% of all ED visits in the < 19yo age group were for mental health
326.8 visits/10,000 people/year were psychiatric
• 13.6% diagnosed as suicide attempt
• 10.8% diagnosed as acute psychosis
• Largest increase seen in nonurgent diagnoses (i.e. same as non-psych
visits)
Increase felt to be due to decreased availability of mental health
providers (actual numbers vs. access)
1995 to 1999 (Page)
59% increase in pediatric psychiatric visits to a children’s hospital
ED
Scope of the Problem
Higher rate of admissions
1 year study by Khan, et al ‘02
227 children with psychiatric illness evaluated
• 32% admitted
60% to medical floors due to lack of facilities for
mental health
Longer turn around times to discharge, admission
and transfer to floor when compared to non-psych
19,734 children with non-psychiatric illness evaluated
• 5.5% admitted
Scope of the Problem
Suicide
2 million US adolescents attempt suicide each
year
2000 succeed
Third leading cause of death for age 15-24
years
Fourth leading cause of death for age 10-24
years
19% of US adolescents report serious
consideration of suicide in the past year
Scope of the Problem
PECARN workgroup
5 site project to define
incidence and character
of psychiatric
emergency visits to
pediatric emergency
departments and to
develop intervention
strategies to address
increasing utilization
“Psych” vs. “Non-psych”
An artificial distinction based on our lack of
knowledge and understanding of
psychiatric illness
Seizures used to be a psychiatric diagnosis
Schizophrenia now understood in a physiologic
model with increased dopamine levels
Many psychiatric problems are exaggerated
responses of normal coping and adaptive
functions in the brain/psyche (i.e. PTSD, Panic
Attacks, Dissociative Disorders)
General Approach
Crisis intervention
Usual coping and adaptive patterns of child and
family disrupted
Risk to patient’s health and wellbeing
Risk to patient’s safety
Risk to others
Assessment, treatment and disposition must
include the child and the family
Ensure physical and emotional safety of child
Provide support and nurturance
Set limits on behavior
The ED environment
Everything should be done in a non-judgmental and
caring manner
“Check your own pulse first”
Patients should be searched
Removal of weapons or drugs that might be used to hurt self or
others
Clothing should be removed and confiscated
Decreases elopement
Place in a safe and quiet environment
Decrease stimulation
Minimize access to dangerous materials
Chemical or physical restraints as necessary and
appropriate
Evaluation
Orienting data
Relevant history
Acute vs. sub-acute
presentation
Medical history and
physical examination
Assess for organic causes
Mental status of the
patient
Assess for organic causes
Define specific problem
Family evaluation
Disposition viability
Mental Status Exam
Orientation
Appearance
Memory
Acute and remote
Cognition
concentration
Behavior
Relating ability
Speech
Pressured?
Affect
Thoughts
Looseness of
associations
Flight of ideas
Hallucinations
Insight and judgment
Strengths
Synthesis
Ancillary studies
Not generally
necessary if history
and physical can
exclude organic
etiology of symptoms,
however, reasonable
considerations
include:
Ancillary studies
Urine or serum drug
screens
Assessment of
pregnancy in females
Chemistries
CBC
ABG
Liver enzymes
Thyroid studies
LP
CT/MRI
Blood lead level
Ammonia level
HIV/RPR
ESR/ANA
Cortisol
EEG
Toxidromes
Sympathomimetics
Tachycardia/HTN/hyperthermia/euphoria/dilated pupils
Opioids
Pinpoint pupils/bradypnea/hypotension
Anticholinergic delirium
“red as a beet, dry as a bone, blind as a bat, and mad
as a hatter”
Cholinergic excess
SLUDGE
Extrapyramidal symptoms
Required work-up for “medical clearance”
Grady 13b
CBC, BMP, UDS, Urine Beta for females
Peachford Pediatric Psychiatric Hospital
UDS and Urine Beta for females
Rest depends on your judgment
Pharmacotherapy
Agitated, violent or psychotic patients
Antihistamines
Benzodiazepines
Neuroleptics
Atypical antipsychotics
Mood stabilizers primarily for bipolar disorder
Lithium
Depakote-better for childhood bipolar
Tegretol-better for childhood bipolar
Benzodiazepines
Ativan 0.05-0.1mg/kg/dose
Rapid sedation
No active metabolites
Short half-life
Route: PO/IM/IV/PR/SL
Problems
Respiratory depression
Paradoxical reaction
• Worse in developmentally delay or organic brain
syndromes
Neuroleptics
Antipsychotic effects take 7-10 days, but
sedation immediate
Haloperidol
Children: 0.025-0.075mg/kg/dose (max 2.5mg)
>12yo: 2-5mg/dose
Route: PO/IM (IV with caution)
Problems
EPS
• Treat with diphenhydramine or benztropine
NMS
• Treat with Dantrolene
Droperidol
Better sedation than Haldol
“Black box” warning for prolongation of QT
interval leading to Torsades de Pointes
Several new studies disputing this point
No strong evidence to support a causal relationship
between use of Droperidol and fatal arrhythmias
Dose 0.03-0.07mg/kg/dose (max 2.5mg)
Problems
Orthostatic hypotension
Serotonin syndrome (esp. seen with LSD)
Atypical antipsychotics
Lower incidence of EPS
Ziprasidone
No dosage info available for children
Associated with prolonged QT
Olanzapine
Route: ODT/IM
0.12-0.29mg/kg/dose
Combo therapy
Diphenhydramine with
Neuroleptics/Atypical antipsychotics
Reduced EPS
Increased sedation
Benzodiazepines with
Neuroleptics/Atypical antipsychotics
Increased sedation
Depression
Inflexible sad mood
Anxiety
Self-deprecation
Loss of functioning
Suicidal/homicidal
ideation
Most important aspect
to assess
Associated with
School problems
Chronic illness
Genetic predisposition
Developmental
differences
Infancy
Childhood
Adolescence
Suicide
Most acute aspect of
psychiatric emergencies
Greatest benefit from
intervention
Suicidal tendencies are
typically fleeting with
increases after stressors,
but decrease to zero
within several weeks after
the acute event in most
adolescents
Suicide Stats
Rare before puberty, but not non-existent
Age perceptions of death
Attempts more common in females
Ingestions most common method in attempts
Completion more common in males
Firearms most common method in completed attempts
Neighborhood
Rural-firearms
Suburban-carbon monoxide
Urban-jumping from buildings
Suicide attempts via ingestion in age 5-14 years 5 times
more common than all forms of meningitis
Completed suicides
>90% have a psychiatric condition
Depression and substance abuse
Psychosis (small percentage, but
high risk)
Impaired judgment,
hallucinations, delusions of
persecution
1/3 have made previous attempts
1/2 have been ill for over 2 years
Family history of suicide
History of physical or sexual abuse
Gay, lesbian or bisexual sexual
orientation
Assessment
ASK!!!
Frequency of thoughts about suicide
Intensity of these thoughts
Duration of these thoughts
Specificity of plan
Hopelessness
Rapid denial in apparent significance
of attempt worrisome
Remember that lethality of past
attempts is not synonymous with
intention!!!
Treatment
Psychiatric consultation
Never prescribe antidepressant
medications
Encourage family to tell patient they want
him or her to live and that suicide is
forbidden
Tender, but firm with setting boundaries
Disposition
Inpatient
No studies exist that
show a reduction in risk
of future suicide
attempts or completed
suicides for patients
hospitalized
Outpatient
Follow up within days
“Sanitized” residence
Contract for safety
No evidence this
prevents suicide
