Page 2: Cyanide intoxication

Background

• There are a lot of substances that may cause someone experiencing a poisoned until it brings a death.

• Substances that active chemically and physiology in one body, at the point of certain dose (toxic) will bring an unhealthiness or may cause a death.

• Forensic discuss about toxic substance from its varies, symptoms caused, and method forensic examination to handle either for alive or dead victims.

Page 3: Cyanide intoxication

Scope of Matters• Toxicology definition and factors that affect

toxicity• Epidemiology, signs and symptoms,

pharmacokinetic, laboratory examination, and treatment/therapy of cyanide poisoning

• Forensic examination of patient that experiencing common poison and cyanide poison

• medikolegal aspects of deliberate poisoning or unintentionally

• Example case of cyanide poisoning

Page 4: Cyanide intoxication

Toxicology Definition

• As a part of medical science that focused on toxic

• Study about nature and mechanism of toxic effect, varies substance towards living things and other biologic system

• A study about source, characteristic and a savor from toxic, indication and treatment against poisoning and other abnormality found in dead victim

Page 5: Cyanide intoxication

Toxic Definition

A substance that may cause bad effect when it gets into a body of a living things, either intentionally or unintentionally

Page 6: Cyanide intoxication

Toxic

• Origin:• Plants (opium, cocaine, curare, aflatoxin)• Animals (poison/snake toxin, spider/marine

animals)• Mineral (arsenic, plumbum, and things that

made from synthetic)• Heroin

Page 7: Cyanide intoxication

Toxic• Venue:• Nature-free (poison gas in nature, household)• Poison agriculture (insecticides, herbesida, pestici

des)• Toxic industrial laboratories and industry

(acid and strong base, heavy metals)• Toxic food(CN in cassava, botulinus toxic,

preservative, additives substance and toxic in the form of medicine e.g. sedative hypnotic)

Page 8: Cyanide intoxication

Toxic• Organs that affected:

• Hepatotosik• Nephrotoxic

• Work mechanism:• Toxic that bind sulfhydryl group (Pb)• Effect on ATP-ase• Forming methemoglobin (nitrate and nitrite)

• The effects:• Local• Systemic• local-systemic

Page 9: Cyanide intoxication

Exposure to toxic substances on humans andliving things:

• regular consumption• exposure from work• environmental exposure and poisoning, either

intentionally or unintentionally

Page 10: Cyanide intoxication

Factors that affect poisoning:

How to enter:• Age• Body condition• Habits• Idiosinkrasi and allergic to vitamin E, penicilin,

streptomycin dan procaine• Time delivery

Page 11: Cyanide intoxication

Cyanide• A deadly toxic substance

• Effects are very fast and can cause death within a few minutes• Hydrogen cyanide (formonitrile)• In the form of liquid -> prussit acid and hydrocyanic acid• Liquids can also be colorless or pale blue at the temperature of normal room• volatile and flammable• diffuse either by air and explosives• Very easy to mix with water• Otherforms: sodium cyanide and potassium cyanide (powder and white)

Page 12: Cyanide intoxication

Epidemiology• a major contributor

to morbidity and mortality, observed in approximately 5,000 to10,000 deaths occur from inhaling fog each year in the united states

• Exposure suicide rarely reported to poison centers and 18 of 242 (in 2007) and 25 of238 (in 2008) cases of cyanide poisoning is deliberate exposure as reported to the American Association of Poison Control Centers

• fatal suicide in adult patients may easily be associated with sudden death from myocardial infarction, pulmonary embolism, or ventricular dysrhythmias

Page 13: Cyanide intoxication

Source• Low-dose in nature and in every product that we

usually eat or use• Cyanide can

be produced by bacteria, fungi and algae• Cyanide is found in cigarettes, motor vehicle

fumes, and food and the synthetic product• Cyanide in seed plants,especially grains (cassava

wild, wild tubers, Intersection buffoonery, wild cherry, plum, apricot, wild amigdalin, jetberry bush, etc.)

Page 14: Cyanide intoxication

Exposures

• Fog Inhalation• Intentional poisoning (suicide)• Industry exposure• Iatrogenic exposure• Consumption

of Supplements Containing Cyanide (Uncommon)

Page 15: Cyanide intoxication

Pharmacokinetic• Cyanide in the body will inactive some oxidative enzymes radically the

whole system, especially cytochrome oxidase by binding to the ferric heme group from the oxygen carried by blood

• The process of oxidation and reduction occurs as follows:

• Cytochrome oxidase Fe + + Fe + + + cytochrome oxidase+ CN /---- Fe + + + cytochrome oxidase-cyanide-

Oxidize cyanide d in the body get into cyanates and sulfosianat and expelled from the body through urine. Toxic dose orally for HCN is 60-90 mg, while doses toxic to KCN or NaCN is 200 mg.

Page 16: Cyanide intoxication

Signs and Symptoms• Main effects: hypoxia system arise progressively

Symptoms and physical signs that found are depend on the• The dose of cyanide• Number of exposures• Type of exposure• Types of cyanide component

• symptoms in the body:• blood pressure, vision, lung, central nerve, heart, endocrine system, autonomic system and metabolic system• sore eyes because of irritation and difficulty breathing due to irritate the respiratory tract mucosa• high concentrations only within 15 seconds hiperpnea, 15 seconds to lose consciousness. 3 minutes of apnea is a period of 5-8 minutes will cause the heart muscle activity is hampered due to hypoxia and ends with death

Page 17: Cyanide intoxication

• Exposure of hydrogen cyanide may cause irritation against eyes and skin immediately after exposure or at least 30 to 60 minutes

• In low concentrations, the effects of cyanide emerging about 15-30 minutes later

• Early signs of cyanide poisoning:• Temporary hiperpnea• Headache• dyspnea• Anxiety• Changes in behavior such as agitation and restlessness• Sweating a lot, reddish skin color, body feels weak and vertigo

Page 18: Cyanide intoxication

• cyanosis of the face, the foam out from the mouth, rapid and weak pulse, rapid breathing and sometimes irregular, dilated pupils and slower reflex, air breathing smells tonsil, the vomit also smells • By the death, cyanosis more real and arise twitch muscles and convulsions with urinary incontinence and alvi

Page 19: Cyanide intoxication

•Inhalation: palpitations, difficulty to breath, nausea, vomiting, headache, salvasi,lakrimasi, mouth and throat irritation, dizziness and weakness of extremities arise quickly and then collapse, convulsions, coma and death• Chronic poisoning victim looks pale, cold sweats, dizziness, discomfort in the stomach, nausea and colic, feel pressed on the chest and shortness of breath.• Signs the end: coma and dilated pupils, tremors, arrhythmias, convulsions, coma emphasis on the respiratory center, respiratory failure until the heart stop beating• color skin looks "cherry-red"

Page 20: Cyanide intoxication

Examination

• Filter paper test• Reaksi Schonbein – Pagenstecher (Guajacol

Reaction)• Prussian Blue Reaction• Micro Method Gittler & Golabaum

Page 21: Cyanide intoxication

Therapy

• Poisoned by CN inhalation:->move victim to the place where clean air is available, give-amyl nitrite with inhalation, 1 ampoule (0.2 ml) every5 minutes, stop giving when the systolic blood pressure is less than 80 mmHg-> give artificial respiration with 100% oxygen->Antidotum in the form of sodium nitrite 3% IV-> vary the dose of sodium nitrite and sodium thiosulfate with Hb

Page 22: Cyanide intoxication

• CN poisoning ingested• do an emergency action with inhalation of amyl nitrite, one ampoule (0.2 ml,within 3minutes) every 5 minutes• Give artificial respiration with 100% oxygen.• Besides nitrite, methylene blue 1% 50 mL IV can be used as antidotum

Page 23: Cyanide intoxication

Forensic Medical Examination

• cases of deaths due to poisoning:• Examination at the place of incident• Outdoor examination- smell- Clothes- Bruises corpse- Changes in skin color- Nails- Hair- sclera

Page 24: Cyanide intoxication

Body Surgery

• Open chest and abdominal cavity,specify whether there is an unusual smell (smell of poison)• Consider the color of blood and the color of organs is brown reddish • In lung, there is an acute damming

Page 25: Cyanide intoxication

Material Sampling for Toxicology Examination

• Taking blood from the heart separately from the right and left respectively for about 50 ml• Blood side for about 30-50 ml, taken from of iliac vein• Urine and gastric washings all of taken from the bladder• Organ liver should be taken after reserved for pathology anatomy examination

Page 26: Cyanide intoxication

• Kidneys should be taken both• Brain, lipoid system inside• another way to take samples:Get the place where toxic gets in (stomach, the injection site)BloodOut point (urine, bile)

Page 27: Cyanide intoxication

Medical Forensic Examination for Cyanide Poisoning

-Examination of the exterior of the body -> wafted of tonsils-Cyanosis of the face and lips, foam out of the mouth, and bruised corpse light colored-Surgical examination of the corpse -> wafted of specific tonsils distinctive when opening the chest cavity , stomach, brain and also stomach, blood, muscle and body sections color seems red bright

Case Discussion

Page 32: Cyanide intoxication

Closing• Toxicology can be defined as

a substance that can cause bad effect when it gets into a living body, either accidentally or with intent.• One type of poisoning that occurs is cyanide poisoning, because the cyanide salt in a small dose is enough to cause death in someone quickly like a suicide.• Poisoning can through parenteral administration, inhalation, ingestion or skin absorption (dermal).• Signs and symptoms depend on the mechanism, source and quantity of cyanide that gets into the body.

Page 33: Cyanide intoxication

• Forensic through the post-mortem examination and toxicology tests can prove the existence of cyanide in the body, or any changes and abnormalities consistent with cyanide poisoning.• Aspect medikolegal about cyanide poisoning regulated in KUHP articles 205, 359, 360; KUHAP 133, Law No. 8 of 1999 about consumer protection Article 19 and 60.
