Adapted From Temple College EMS Professions Poisoning/Alcohol/Overdose
Poisons • Substance which when introduced into body in relatively small amounts causes in structural damage or functional disturbances
Suspect with: • GI signs/symptoms (nausea, vomiting, diarrhea, pain) • Altered LOC, seizures, unusual behavior • Pupil changes, salivation, sweating, other signs/symptoms of disturbed autonomic nervous system function • Respiratory depression • Burns, blisters of lips, mucous membranes • Unusual breath odors
Treat Patient, Not Poison • Proper support of ABCs is first step in management • Contact with Poison Control Center • Priority action plan • Symptomatic treatments • Time management
Try to determine: • What? • How much? • How long ago? • What has already been done? • Psychiatric history? • Underlying illness?
When in doubt. . . • Assume containers were full • Entire contents were ingested • Patient may not be telling you the truth
If several patients involved. . . • Assume each ingested entire container contents • Triage • Additional resources
Always. . . • Bring sample of material if possible • Save for analysis, if patient vomits
Poisoning Management • Based on route of entry • Ingested • Absorbed • Inhaled • Injected
Ingested Poisons • Prevent absorption of toxin from GI tract into bloodstream • Positioning • Rapid Transport to definitive treatment center
Absorbed Poisons • Dry chemicals • dust skin, then • wash • Liquid chemicals • wash with large amounts of H20 • avoid “neutralizing” agents CAUTION Don’t accidentally expose yourself!
Inhaled Poisons • Remove patient from exposure • Maximize oxygenation, ventilation CAUTION Don’t accidentally expose yourself!
Injected Poisons • Attempt to slow absorption • Venous constricting bands • Dependent position • Splinting of injected body part • Cold packs (+) [May worsen local injury by concentrating poison]
Substance Abuse • Self administration of a substance in a manner not in accord with approved medical or social practices
Substance Abuse • Psychological dependence • Physical dependence • Compulsive drug use • Tolerance • Addiction
Psychological Dependence • Habituation • Substance needed to support user’s sense of well-being
Physical Dependence • Substance must be present in body to avoid physical symptoms (withdrawal)
Compulsive Drug Use • Use of drug and rituals/culture associated with its use become an overwhelming desire
Tolerance • Increasing amounts of drug needed to produce same effects • Tolerance contributes to addiction by keeping user “chasing the last high”
Addiction • Combination of psychological dependence, physical dependence, compulsive use, and tolerance • Patient becomes totally consumed with obtaining, using drug to exclusion of all other things
Ethanol Intoxication Signs • Breath odor • Swaying, unsteadiness • Slurred speech • Nausea, vomiting • Flushed face • Drowsiness • Violent, erratic behavior
Ethanol • Clouds signs, symptoms • Complicates assessment • Head trauma, diabetes, drug toxicity, CNS infection can mimic EtOH intoxication and vice versa
Patient is NEVER “just drunk” until all other possibilities are excluded
Experience alcohol withdrawal syndrome if they reduce intake: Restlessness, tremulousness Hallucinations Seizures Delirium tremens--all of above plus tachycardia, nausea, vomiting, hypertension, elevated body temperature Alcohol Addicts
Life threatening condition! Occurs 1 days to 2 weeks after intake is decreased 5 to 15% mortality Control airway, prevent aspiration, monitor for hypovolemia Delirium Tremens
Narcotics • Opium • Opium derivatives • Synthetic compounds that produce opium-like effects
Narcotics • Percodan • Codeine • Darvon • Talwin • Opium • Heroin • Morphine • Demerol • Dilaudid
Narcotics • Medical Uses • analgesics • anti-diarrheal agents • cough suppressants
Narcotics • Overdose • Coma • Respiratory depression • Constricted (pin-point) pupils
Narcotics • Withdrawal • Agitation • Anxiety • Abdominal pain • Dilated pupils • Sweating • Chills • Joint pains • Goose flesh Resembles severe influenza Not a life-threat
Nembutal Seconal Pentobarbital Amytal Tuinal Phenobarbital Barbiturates
Induce sleepiness, state similar to EtOH intoxication Medical uses Anesthetics Sedative Hypnotics Barbiturates
Barbiturates Overdose Coma Respiratory depression Shock Extremely dangerous in combination with EtOH
Barbiturates Withdrawal Resembles EtOH withdrawal (DTs) Extremely dangerous
Barbiturate-like Non-barbiturates Doriden, Placidyl, Quaalude, Methyprylon Effects similar to barbiturates Overdose can cause sudden, very prolonged respiratory arrest Withdrawal resembles ETOH; extremely dangerous
Valium, Librium, Miltown, Equanil, Tranxene Low doses relieve anxiety, produce muscle relaxation High doses produce barbiturate-like effects Tranquilizers
Overdose: Unlikely to cause respiratory arrest alone Extremely dangerous with EtOH Withdrawal Resembles EtOH withdrawal Extremely dangerous Tranquilizers
CNS Stimulants: Amphetamines • Dexedrine, Benzedrine, Methyl amphetamine • Relieve fatigue, promote euphoria, reduce appetite
CNS Stimulants: Amphetamines • Overdose • Restlessness, paranoia • Tachycardia • Hypertension CVA, Heart failure • Hyperthermia Heat stroke • Withdrawal • Lethargy • Depression
Stronger stimulant effects than amphetamines Can cause respiratory/cardiovascular failure, heat stroke, lethal arrhythmias CNS Stimulants: Cocaine
“Snorting” can destroy nasal septum, cause massive nosebleed Airway issue Withdrawal: lethargy depression CNS Stimulants: Cocaine
LSD, psilocybin, peyote, mescaline, DMT, MDMA Enhance perception Wrong setting may induce “bad trips” with extreme anxiety True toxic overdose rare Hallucinogens
Phencyclidine • PCP, angel dust • Produces bizarre, violent behavior • Reduces pain sensation • Patients may be capable of feats of extreme strength • Keep patient in quiet environment, minimize stimulatin
Glue, paint, gas, light fluid, toluene Inhalation produces state similar to EtOH intoxication Patient may asphyxiate if consciousness lost while “sniffing” Solvents
Increase risk of arrhythmias May cause liver damage, bone marrow depression Chronic abuse causes CNS damage - paranoia, violent behavior Solvents
