ORGANOPHOSPHATES

NeuroToxinsNeuroToxins

• Neuro Toxins– Organophosphate Pesticides

• Parathion, Malathion, Methyl Parathion

– Carbamate Pesticides• Sevin, Carbofuran, Furodan, Aldicarb

– Chemical Weapons - Nerve Agents• Sarin, Soman, VX, Tabun

Organophosphate PesticidesOrganophosphate Pesticides

• Highly Toxic– Tetraethyl

Pyrophosphate (TEEP)

– Fensulfothion– Mevinphos

(Phosdrin)– Ethyl parathion– Cyanofenphos

(Surecide)– Methyl Parathion

• Moderately Toxic– Leptophos

– Ethion

– Chlorpyrifos (Dursban)

– Diazinon

– Malathion

NeuroToxinsNeuroToxinsReaction time (onset of symptoms) depends on:

• Type of agent involved (concentration, specific agent)

• Dose (how much patient absorbed)

• Duration (how long are they exposed)

• Route of exposure (inhalation, absorption, ingestion)

• Sensitivity of patient's system

Page 7: Antidote Course - Ohio 2016 Course - Ohio.pdf · •Ohio Hazmat Teams Conference •11/4/2017 •2 National Governors Association January 5, 2006 Mark Vedder • Battalion Chief,

•7

• More than 12,000 exposures treated annually in the US

• Most common in agricultural workers, who may under report.

• Most exposures are from skin absorption.

• Suicides and homocides.

Pesticide PoisoningPesticide Poisoning

• Acetylcholine normally stimulates contraction of muscles and/or secretion of glands

• Acetylcholinesterase breaks down acetylcholine to relax the muscle contraction or stop gland from secreting

• Organophosphates block acetylcholinesterase causing excess parasympathetic nervous system activity

Organophosphate PoisoningOrganophosphate Poisoning

Organophosphate PoisoningOrganophosphate Poisoning

• Symptoms usually within 4 hours of exposure

• Flu-like with headache, N/V• Muscle twitching, loss of coordination• Abdominal cramps and diarrhea• Hypersecretion• Blurred, darkened vision• Wheezing, cough, secretions • Pulmonary edema

Organophosphate ToxicityOrganophosphate Toxicity

• Muscarinic effects tend to dominate– Bradycardia

– Hypersecretion

– Bronchospasm

– SLUDGEM

– Diaphoresis

– Blurred vision

• Some Nicotinic effects commonly seen– Skeletal muscle

fasciculations

– Cramping

– Respiratory muscle weakness

OP Presentation - continuedOP Presentation - continued

• Bradycardia– may be preceded by tachycardia

– early nicotinic stimulation

– may progress to sinus arrest

• Toxic psychosis

• Respiratory depression, convulsions, unconsciousness, flaccid paralysis

OP Treatment - 1OP Treatment - 1

• With strong clinical indications of OP poisoning, do not delay treatment while waiting on proof

• Protect all who will handle the patient

• Decontaminate

• If OP is ingested, beware of emesis

Page 10: Antidote Course - Ohio 2016 Course - Ohio.pdf · •Ohio Hazmat Teams Conference •11/4/2017 •2 National Governors Association January 5, 2006 Mark Vedder • Battalion Chief,

•10

OP Treatment - 2OP Treatment - 2

• Atropine– 2 - 4 mg IVP every 5 minutes

– May require massive doses

– No arbitrary end point in atropine dosage (NOT tachycardia)

– Titrate dose to drying of secretions

– Then IV maintenance drip .2-2mg/hr

– Long term therapy may be needed

AtropineAtropine

What does the Atropine do?• Atropine blocks

effects of over-stimulation

• Relieves smooth muscle constriction

• Dries up respiratory secretions

Page 11: Antidote Course - Ohio 2016 Course - Ohio.pdf · •Ohio Hazmat Teams Conference •11/4/2017 •2 National Governors Association January 5, 2006 Mark Vedder • Battalion Chief,

•Ohio Hazmat Teams Conference •11/4/2017

•11

OP Treatment - 2OP Treatment - 2

• Pralidoxime (2 PAM)– 1-2 g in 100cc saline IV over 15-30 min

– binds to the Organophosphate

– releases it from the ACHE

– acts at Nicotinic and Muscarinic sites

– may result in need for less Atropine

– most effective early in the event

– onset of actions within 30 minutes

2-PAM Chloride2-PAM Chloride

What does 2-PAM Chloride do?

• Reactivates acetylcholinesterase• Helps re-establish normal skeletal muscle

contraction• Helps relieve twitching and paralysis of respiratory

muscles

OP Treatment - 3OP Treatment - 3

• Conventional pulmonary edema therapy should not be used until the full benefit of Atropine has been realized

• Monitor respirations

• Anticonvulsants for seizures PRN

CARBAMATES

Carbamate PesticidesCarbamate Pesticides

Carbamates• Same symptoms as Organophosphates

• Tend to be less toxic than OP

• Not as long lasting

• Carbamates do not age

• Higher survival rates

ASPHYXIANTSASPHYXIANTS• Chemical Asphyxiants

• Affect all cells by inhibiting cellular respiration causing systemic hypoxia.

• Binds with cytochrome oxidase enzyme which prevents ATP (energy) production in the cells, causing anaerobic metabolism and acidosis

Chemical Asphyxiants

Examples:• Cyanides

– 1982 Tylenol Contamination– 1978 Peoples Temple – Mass Suicide

CyanideCyanide• What is it?

• Carbon & Nitrogen (CN)• Very strong triple bond• Aka: Hydrocyanic acid/prussic acid

• Physical Properties of HCN• Colorless gas or pale blue liquid• BP = 78 degrees F• VP = 630 mmHg at 68 degrees F• VD = 0.94• LEL = 5.6%

CyanideCyanide• Where does it come from?

• Found in some seeds and fruit stones• Apple, mango, peach, cherry

• Produced as a by-product of incomplete combustion• Many plastic materials release it when heated or burned

• What is it used for?• In mining, cyanide dissolves silver and gold from ore• Medical uses in vasodilators and vitamin B12• Nitrile production• Electroplating of metals

•28

CyanideCyanide• Smoke Inhalation?

• Part of the “Toxic Twins” – CO and CN• Increased use of synthetics in building materials and

contents• No strong correlation between CO and CN levels• They may potentiate each other• Cyanide causes a “knock down effect” at sub lethal levels• Should be suspected if

• Closed space fire• Soot around nose and mouth• Altered LOC• Hypotension

CyanideCyanide• Smoke Inhalation?

• Must be a presumptive diagnosis• Blood Test results take hours to days

Traditional Cyanide KitsTraditional Cyanide KitsTherapeutic Action• Nitrites change some hemoglobin to methemoglobin. • Cyanides & sulfides prefer and are attracted to

methemoglobin. They bind and reduce the toxic effect.• Thiosulfate then helps convert the cyanomethemoglobin to

the much less toxic thiocyanate and be excreted in urine.• Side effects: hypotension, nausea, hypoxia

• NOT FOR USE WITH SMOKE INHALATION

CN TreatmentCN TreatmentCyanokit• Hydroxocolbalamin – Precursor to B12• Attracts cyanide and binds to form

cyanocobalamin (vitamin B12)• Does not affect hemoglobin• Contraindications: None for

cyanide poisoning

Hydrogen SulfideHydrogen SulfideHydrogen Sulfide• Cyanokit will not work for H2S

• Break Amyl Nitrite Pearls and hold near mouth or nose for 15 seconds and then away for 15 seconds. This is immediate first aid only while IV is established.

• After IV established, inject 300 mg (10 mL of 3% solution) of Sodium Nitrite at a rate of 2.5 – 5 mL per minute

• NO Sodium Thiosulfate is administered for H2S.

• Closely monitor EKG and Blood Pressure

Hydrofluoric AcidHydrofluoric AcidHydrogen Fluoride or Hydrofluoric Acid• Anhydrous or Solution of Hydrogen Fluoride in water• Considered a weak acid (pH of 3 – 4.5)• But highly corrosive acid capable of corroding many

materials, including highly reactive to glass

Used in:• Metal manufacturing/finishing• Glass etching & Ceramic production• Oil Refining• Electronic component production• Production of Teflon and Freon• Pharmaceutical manufacturing• Some consumer products

Hydrofluoric AcidHydrofluoric AcidHydrofluoric Acid• Used in various concentrations from 3% to 99.9%• Commonly in 99.9%, 70%, 49%• Clear, colorless liquid• Over 40% concentration will produce pungent vapors• Most non-industrial products are < 15%• Many industrial processes use 50-100%

Hydrofluoric AcidHydrofluoric AcidHydrofluoric Acid• Penetrates tissue more rapidly than

mineral acids• Cause deep burns followed by tissue

death• Systemically toxic from dermal

exposure • HF gas can injure eyes, lungs and

skin• HF gas is also released as a by-

product of combustion from materials like Teflon

Hydrofluoric AcidHydrofluoric AcidHydrofluoric Acid• HF interferes with nerve function which may reduce and

delay pain at lower concentrations• Once absorbed, seeks calcium and magnesium

• Draws calcium from cells affecting cellular function• Decalcifies bone (chemical osteoporosis)• Affects cardiac muscle cells causing V-Tach and V-Fib

Hydrofluoric AcidHydrofluoric AcidSeverity• Concentrated HF liquid or vapor may cause

• Severe Burns• Metabolic imbalance due to fluoride toxicity• Pulmonary Edema• Life threatening cardiac dysrhythmias

Hydrofluoric AcidHydrofluoric AcidSeverity of Burns• Depends upon concentration, temperature and duration • High concentrations (over 50%)

• Immediate severe burning pain• Whitish discoloration of skin• Formation of blisters

• Concentration 20-50%• Delay of clinical signs for 1-8 hours

• Concentration <20%• Latent period of up to 24 hours

Hydrofluoric AcidHydrofluoric AcidHypocalcemia• Burns larger than 25 sq inches may result

in systemic toxicity• Causes intermittent QT prolongation• Life threatening cardiac electrical instability• High risk of torsades de pointes (v-tach)

Hydrofluoric AcidHydrofluoric AcidBurns• HF burns are different than most acid burns as they cause

liquefaction necrosis• HF skin burns are accompanied by severe throbbing pain• Relief of pain is an important guide to the success of

treatment!• Treatment of HF burns is different than other chemical burn

care

Hydrofluoric AcidHydrofluoric AcidSkin Burn Treatment• Directed toward binding the fluoride ions to

prevent tissue destruction.• Wash with water, then:• Iced or chilled Benzalkonium Chloride (Zephiran) as

soaking agents; and/or • Calcium Gluconate (2.5%) as gel or ointment; and/or• Calcium Gluconate solution (5%) injected SQ or IV• Continue until pain subsides• Speed is of the essence!!

Hydrofluoric AcidHydrofluoric AcidEye Exposure Treatment• Directed toward binding the fluoride ions to

prevent tissue destruction.• Flush with water or saline, then:• Topical Tetracaine Hydrochloride for pain relief• Irrigate with calcium gluconate (1%) solution

• NEVER use Zephiran to irrigate eyes• Speed is of the essence!!
