Behavioral Emergencies PARAMEDIC PROGRAM P. Andrews Summer 07 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. What’s this all about? Is it normal or abnormal? Prevalence? Pathophysiology of behavioral and psychiatric disorders Factors that alter behavior or emotional status Medical legal considerations Overt behaviors associated with behavioral and psychiatric disorders Verbal techniques useful in mgmt of the emotionally disturbed pt. Appropriate safety measures When should family, etc be removed from premises? Techniques for physical assessment When are you expected to transport a patient against his/her will? To restrain or not? Terms Affect Anger Anxiety Confusion Depression Fear Mental status Open-ended questions Posture Post-traumatic stress syndrome Psychogenic amnesia Schizophrenia Bereavement Biological/organic Bipolar disorder Catatonia Delirium Delusions Dementia Flat affect Manic Multiple personality disorder Phobia Positional asphyxia Behavioral and Psychiatric Emergencies Not clear cut They require a complete history, exam, and careful/skilled approach Most of what you do will depend on your people skills Behavioral emergency Behavior is so unusual, bizarre, threatening or dangerous – possibly life-threatening to self or others What is normal, anyway??? Determined by Does it Culture Ethnic groups Socioeconomic class Personal interpretation, opinion Interfere with core life functions? Pose a threat to the life or well-being of the patient or others? Significantly deviate from society’s expectations? Normal ? Behavior that is readily acceptable in a society! Pathophysiology ~ 20% of population has some type of mental health problem 1 in 7 will require treatment Anxiety Depression Eating disorders Mild personality disorders Behavioral and psychiatric disorders incapacitate more people than all other health problems combined! True/not true? All mental patients are unstable and dangerous Their conditions are incurable Biological causes Alcohol Drugs (including OTC, Rx) Infection Tumors Potential Organic Causes Frontal atrophy from Alzheimer’s disease Brain neoplasm Psychosocial Personality style Dynamics of unresolved conflict Crisis management methods Environment Traumatic childhood incidents Sociocultural Situational Relationships Support systems Social isolation Rape/assault Witnessing acts of violence Loss of a job Ongoing prejudice or discrimination Assessment of behavioral patients The same as for all other patients Scene size-up – look for hazards Initial assessment – watch posture & body language Focused history Physical examination You begin your care at the same time – good interpersonal skills, remember? More about the H & E Listen – open-ended questions Pay attention Spend time Be assured Do not threaten Let there be silence Place yourself at their level Keep a safe & proper distance Appear comfortable Don’t judge Never lie Mental status examination General appearance Behavioral observations – verbal and non-verbal behavior Orientation Memory Sensorium – is pt. Focused, paying attention? Perceptual processes – thought patterns ordered? Mood and affect Intelligence Thought processes Insight Judgment psychomotor Form a general impression Dementia 25 – 50% over 85 y/o have dementia Affected person sometimes recognizes first signs Alzheimer’s most common Mini-strokes Keys? Lost while driving, etc Common tasks Difficulty with words Time between first symptoms & death – 7 – 10 years Dementia Gradual impairment of memory and cognitive functions Forgetfulness Failure to recognize objects or stimuli Orientation Excellent recall of past history May not remember current events Affect Aphasia Impaired motor activities Agnosia Impaired communication Apraxia Normal or flat, depending on stage of condition Failure to recognize objects Disturbance in executive functioning Impaired ability to plan, organize or sequence Causes: Alzheimer’s disease AIDS Parkinson’s disease Vascular disease Head trauma Substance abuse Dementia and Delirium Delirium may occur in dementia patients Delirium Presentation Rapid onset (hours or days) Inattention, disorientation, memory impairment and visual hallucinations Causes of delirium are usually reversible Rule out acute medical problems, medication changes Treatment Supportive Meds Aricept Cognex Schizophrenia Gross distortions of reality Preoccupation with inner fantasies Withdrawal from social interaction Disorganization of thoughts, perceptions, and emotions Behavior linked with medication noncompliance Chronic substance abuse in teenage years linked to development of the disease Schizophrenia Symptoms Disorganized behavior/dress Flat affect Disorganized speech Delusions Hallucinations Incoherent or frequently veers off track Often auditory; sometimes visual Motor Movements May act upon hallucinations Profiles of Schizophrenic Behavior Delusional: A man who wraps his house in tin foil to divert the rays from FBI satellites. Paranoid: The man introduces himself as Jesus Christ and tells you that the city council is out to crucify him. Profiles of Schizophrenic Behavior Disorganized (interview with a physician): “S____t on you all who rip into my internals! The grudgerometer will take care of you all! I am the Queen, see my magic, I shall turn you all into sidgelings forever!” Profiles of Schizophrenic Behavior Undifferentiated: Magical thinking Creates new words or cryptic language Cannot reason abstractly Diagnosis of Schizophrenia Two or more symptoms must each be present for a significant portion of each month over the course of 6 months. Sx must cause a social or occupational dysfunction Most schizophrenics are diagnosed in early adulthood Approach to a schizophrenic pt. Be supportive Be nonjudgmental Don’t reinforce the patient’s hallucinations – but know that he considers them real Speak openly and honestly Be encouraging and realistic Be alert for aggressive behavior Restrain pt if necessary Anxiety Disorders Panic Attacks Acute, unprovoked episodes Last approximately 1 hour Symptoms: Cardiac chest pain, nausea Dyspnea or a sense of feeling “smothered” Fear of going crazy Paresthesia, dizziness Trembling, shaking Mood Disorders: Mania Sudden onset with rapid progression of symptoms (days) Presentation: Progressive inflation of self-esteem Distracted, racing thoughts Delusions may occur Very talkative with rapid speech Excessive involvement in high pleasure/high risk activities Management for anxiety disorder Simple, supportive Be empathetic Assess medical complaints & tx prn Consider sedative Valium Versed Ativan Benadryl Bipolar disorder One or more manic episodes with or without depression, lasting at least one week Not common Episodes often begin suddenly and escalate rapidly Disorder usually develops in adolescence or early adulthood The Stages of Mania Mild “On top of the world” Egocentric Decreased need for sleep Severe elation Rapid speech Illogical associations Delusions of grandeur Excessive involvement in pleasurable activities with high potential for consequences Mood Disorders: Depression Situational v. persistent Lack of interest in daily activities Altered mood impairs daily functioning May be present with other disorders Bipolar disease Substance abuse Presentation of Depression Bizarre behavior usually not seen in depression Inability to see beyond the person’s immediate situation Lethargy, slow thought process and speech Stooped posture Poor appearance General Management Considerations Behavioral crisis development and management are viewed as a “spectrum” Patients do not suddenly develop anger or passivity Use the scene dynamics wisely to effect patient cooperation Never leave depressed or suicidal patient alone 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 Transport with consent (when possible) without sirens The Spectrum When is it time for patient restraint? Use only when necessary · Patient is a danger to themselves or others · Look for all possible causes for the behavior · Restraints must allow for adequate monitoring of vital signs · Restraints applied by law enforcement must allow sufficient “slack” · Patient must be able to straighten the abdomen and chest and take full breaths The officer must accompany the patient in the ambulance Approved equipment for prehospital personnel Padded leather Soft restraints (posey, velcro, seatbelts) Unapproved methods of restraint for prehospital personnel Hard plastic ties or device that requires a key to remove Backboard, scoop, or flat used to sandwich the patient “Hog - tied” (hands and feet behind the patient) Methods or material that could cause neurovascular compromise Evaluate and document the condition of the restrained extremity (neurovascular check) every 15 minutes. Documentation of Restraint Application Reason the restraints were needed· Which agency applied the restraints· Information and data regarding the monitoring of circulation to the restrained extremity· Information and data regarding the monitoring of respiratory status while restrained Somatoform disorders Somatization disorder Conversion disorder Pt is preoccupied with physical symptoms Loss of function (blindness, paralysis) Hypochondriasis Exaggerated interpretation of physical symptoms Neurotransmitters and Behavior Neurotransmitters: Norepi Promotes awakening and enhances dreams Elevates mood CNS locations: cortex, medulla, hypothalamus, limbic system, cerebellum NE 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 Therapy Top prescribed Rx for 2004 #6 – Zoloft (SSRI) #9 – Zyprexa (Antipsychotic) #13 – Effexor XR (SSRI) #18 – Risperdal (Antipsychotic) #19 – Seroquel (Antipsychotic) #23 – Ambien #47 – Welbutrin (SSRI) #53 – Ablify (Antipsychotic) #58 – Paxil (SSRI) #69 – Adderall (Amphetamine) Additional Top Rx - 2003 Alprazolam Lorazepam Clonazepam Wellbutrin Amitryptiline Trazadone Diazepam Temazepam Remeron (Serotonin stimulant) Concerta (amphetamine) 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, NE 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 NE released Lack of reabsorption drops functional NE 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) Promethazine Intense potentiation of SSRI effects Medical causes of behavioral crises Clues suggestive of a potential medical cause of the behavior Abnormal vital signs Depressed level of consciousness Obtunded Evidence of drug or toxin ingestion Very sudden onset of symptoms Focal neurological signs No previous psychiatric history 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. Suicide 9th leading cause of death overall 3rd leading cause of death in 15-24 age group Women attempt suicide more often, but – men are more often successful Assessing potentially suicidal patients Perform appropriate H & E Provide appropriate psychological care Document observations, especially any detailed plans Risk factors for suicide Previous attempts Depression Age (15-24, & >40) Alcohol or drug abuse Divorced or widowed Giving away personal belongings Living alone/increased isolation Psychosis with depression Major separation trauma Major physical stresses Risk factors, cont. Loss of independence Lack of goals & plans for future Suicide of same-sexed parent Expression of a plan for suicide Possession of mechanism for suicide (gun, rope, pills) Age-related conditions Geriatrics You may mistake depression for dementia Assess their ability to communicate Provide reassurance Compensate for vision, hearing loss Treat with respect Avoid administering medication if possible Take your time Allow family & friends to be with patient Pediatrics Avoid separating young child from parent Make all explanations brief and simple; repeat often Be calm, speak slowly ID yourself Be truthful Encourage child to help with his care Don’t discourage child from crying, showing emotion Allow child to keep favorite blanket or toy Peds, cont. Don’t leave child alone, even for short period If you must be separated from child, introduce care giver who will take over Management of Sudden Death Situations Resuscitate patient unless obviously dead Keep family informed Be truthful Avoid trite phrases Do not offer false hope Empathize/sympathize Allow emotional response Maintain professionalism Management of terminally ill Do not isolate the family Allow feelings to be expressed Provide for patients physical comfort Allow for patients dignity in dying process Resuscitate according to local protocol regardless of a living will Grief Many different reactions Cultural differences Denial Anger Bargaining Depression Acceptance How you doin’? Helplessness/Guilt Anger/Frustration Avoidance Nightmares Gallows humor Physiological response Can you cope? Rest Exercise Humor Hobbies Have a life outside of EMS Talk! Others?
