-CLINICAL EFFECTS

GENERAL CLINICAL EFFECTS

USES: Used for pest control in industrial agriculture (tends to be more toxic agents) to control ectoparasites on farm and companion animals, and for home and garden pest control. Poisoning occasionally occurs from ingestion of contaminated crops or food.

TOXICOLOGY: Carbamates competitively inhibit pseudocholinesterase and acetylcholinesterase, preventing hydrolysis and inactivation of acetylcholine. Acetylcholine accumulates at nerve junctions, causing malfunction of the sympathetic, parasympathetic, and peripheral nervous systems and some of the CNS. Clinical signs of cholinergic excess develop.

EPIDEMIOLOGY: Exposure is common, but serious toxicity is unusual in the US. Common source of severe poisoning in developing countries. Toxicity generally less severe than with organophosphates.

WITH POISONING/EXPOSURE

MILD TO MODERATE POISONING: MUSCARINIC EFFECTS: Can include bradycardia, salivation, lacrimation, diaphoresis, vomiting, diarrhea, urination, and miosis. NICOTINIC EFFECTS: Tachycardia, hypertension, mydriasis, and muscle cramps.
SEVERE POISONING: MUSCARINIC EFFECTS: Bronchorrhea, bronchospasm, and acute lung injury. NICOTINIC EFFECTS: Muscle fasciculations, weakness, and respiratory failure. CENTRAL EFFECTS: CNS depression, agitation, confusion, delirium, coma, and seizures. Hypotension, ventricular dysrhythmias, metabolic acidosis, pancreatitis, and hyperglycemia can also develop.
CHILDREN: May have different predominant signs and symptoms than adults (more likely CNS depression, stupor, coma, flaccidity, dyspnea, and seizures). Children may also have fewer muscarinic and nicotinic signs of intoxication (ie, secretions, bradycardia, fasciculations, and miosis) as compared with adults.
INHALATION EXPOSURE: Vapors rapidly produce mucous membrane and upper airway irritation and bronchospasm, followed by systemic muscarinic, nicotinic, and central effects if exposed to significant concentrations.

-FIRST AID

FIRST AID AND PREHOSPITAL TREATMENT

PREHOSPITAL: Activated charcoal is contraindicated because of possible respiratory depression, seizures, and risk of aspiration. Remove contaminated clothing and wash skin with soap and water. Universal precautions and nitrile gloves to protect personnel. Vomiting should be contained and treated as hazardous material. Rescue personnel should avoid dermal exposure to vomiting because of the risk of intoxication.

There are two primary classes of antidotes: ATROPINE (muscarinic antagonist); OXIMES (pralidoxime in the US, or obidoxime in some other countries) to reverse neuromuscular blockade. Use of oximes is generally indicated for patients with severe toxicity and are used in conjunction with atropine.

-MEDICAL TREATMENT

FIRST AID

PREHOSPITAL DECONTAMINATION/NOT RECOMMENDED

Activated charcoal is contraindicated because of possible respiratory depression, seizures, and risk of aspiration.

PERSONNEL PROTECTION

Universal precaution should be followed by all individuals (i.e., first responders, emergency medical, and emergency department personnel) caring for the patient to avoid contamination. Nitrile gloves are suggested. Avoid direct contact with contaminated clothing, objects or body fluids.
Vomiting containing carbamates should be placed in a closed impervious containers for proper disposal.

DERMAL EXPOSURE

Remove contaminated clothing. Wash skin with soap and water.

EYE EXPOSURE

DECONTAMINATION: Remove contact lenses and irrigate exposed eyes with copious amounts of room temperature 0.9% saline or water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist after 15 minutes of irrigation, the patient should be seen in a healthcare facility.

INHALATION EXPOSURE

INHALATION: Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with an inhaled beta2-adrenergic agonist. Consider systemic corticosteroids in patients with significant bronchospasm.

There are two primary classes of antidotes: ATROPINE (muscarinic antagonist); OXIMES (pralidoxime in the US, or obidoxime in some other countries) to reverse neuromuscular blockade. Use of oximes is generally indicated for patients with severe toxicity and are used in conjunction with atropine.

-RANGE OF TOXICITY

MINIMUM LETHAL EXPOSURE

GENERAL/SUMMARY

There is great variation in toxic/lethal doses between the various carbamates. When available, toxicity should be considered per substance.

SPECIFIC SUBSTANCE

METHOMYL - Ingestion of contaminated food resulted in three fatalities; the estimated lethal dose from this incident was 12 to 15 milligrams/kilogram (Liddle et al, 1979).
METHOMYL - A fatality resulted following inhalation and transdermal absorption of methomyl in a farmer who used this product with no self-protection. Blood concentration of methomyl on admission (prior to death) was 1.6 milligrams/deciliter (Tsatsakis et al, 2001).

PEDIATRIC

CASE SERIES - In a case series of 54 children with anticholinesterase insecticide poisoning from various routes of exposure, no significant differences in incidence of clinical effects were detected according to route of exposure, or state of decontamination. Four of the children died (7%). The presence of a cardiac dysrhythmia (likelihood ratio 8.3) and respiratory failure (likelihood ratio 3.3) were associated with increased likelihood of a fatal outcome (Verhulst et al, 2002).
CASE STUDY - Plasma cholinesterase (ChE) activity was measured in 105 healthy Thai children. The mean was 7,417 +/- 1,620 units/L. This was compared to the ChE activities (470 and 680 units/L) of two children intentionally poisoned with methomyl. The authors concluded that as little as a 10 percent decrease in plasma ChE levels in children may be a lethal anti-ChE poisoning (Ruangyuttikarn et al, 2001).

ANIMAL DATA

CARBOFURAN - The 30-day empirical minimum lethal dosage was 0.2 milligram/kilogram/day for mallards and 4.2 milligrams/kilogram/day for pheasants (HSDB , 2001).

MAXIMUM TOLERATED EXPOSURE

GENERAL/SUMMARY

There is great variation in toxic/lethal doses between the various carbamates. When available, toxicity should be considered per substance.

SPECIFIC SUBSTANCE

CARBAMATE HERBICIDES - There are a number of carbamate herbicides and fungicides used in agriculture which are not cholinesterase inhibitors. The pesticides listed below are cholinesterase inhibitors.
ALDICARB - Aldicarb is a systemic insecticide. It is taken up from soil and translocated into the fruit of some crops in sufficient quantity to cause symptoms of poisoning. Below are some examples of poisoning via contaminated food.

FOOD CONTAMINATION/CALIFORNIA - Illnesses were detected in patients receiving a dose of 0.0011 to 0.06 milligram/kilogram. This amounted to 1/4 to 1 cucumber and 1/2 slice to 5 slices of melon (Goldman et al, 1990).
FOOD CONTAMINATION/NEBRASKA - Illnesses at doses of 0.025 to 0.041 milligram/kilogram of body weight (Jackson & Goldman, 1986; Goes et al, 1980). Severe poisoning requiring hospital treatment only occurred with exposures to more than 0.01 milligram/kilogram (Goldman et al, 1990).
FOOD CONTAMINATION/LOUISIANA - Of 16 persons who ate an aldicarb- contaminated salad, 14 became ill, with predominantly gastrointestinal and neurological symptoms. It was estimated that a 6 gram portion of the salad contained 272.6 parts per million, or approximately 17 milligrams of aldicarb. Thus, a 70-kg adult would have consumed 0.2 milligrams of aldicarb per kilogram of body weight. All the victims recovered following symptomatic therapy (Anon, 1999).
FOOD CONTAMINATION/GREENHOUSES - Two epidemics of poisoning from eating contaminated cucumbers grown in a hydroponic greenhouse have been recorded (Hayes, 1982) with victims becoming ill between 1/2 and 12 hours after ingestion. All recovered without treatment.
FOOD CONTAMINATION/MINT - Eating mint sprigs 24 days after aldicarb soil application caused illness which resolved with atropine (Hayes, 1982).

CASE REPORTS

CARBARYL -

ADULT - A 23-year-old man ingested 500 milligrams/kilogram of carbaryl, the approximate LD50 in rats. The patient survived, but developed a severe delayed peripheral neuropathy (Dickoff et al, 1987).

METHOMYL -

SUMMARY OF CASES - Ingestion of 2 to 16 grams of methomyl products (% not specified) was associated with complete recovery in 8 patients, aged 10 to 60 years.

Treatment included gastric lavage, multiple-dose activated charcoal, and small doses of atropine (0.8 to 6 milligrams).
Plasma cholinesterase normalized within 24 hours in 5 of 7 patients with decreased initial levels (Martinez-Chuecos et al, 1990).
