General dose rate for cattle dogs and cats. 275 mgkg SC qid or 13 mgkg SC IV qid for 5 days then every 2-3 days if necessary.
In such situations the addition of small doses of an adrenergic agent eg.
Organophosphate poisoning atropine dose. Atropine is not an actual antidote for organophosphate poisoning. However by blocking the action of acetylcholine at muscarinic receptors atropine also serves as a treatment for poisoning by organophosphate insecticides and nerve agents such as tabun GA sarin GB soman GD and VX. Organophosphate poisoning is poisoning due to organophosphates OPs.
Organophosphates are used as insecticides medications and nerve agents. Symptoms include increased saliva and tear production diarrhea vomiting small pupils sweating muscle tremors and confusion. While onset of symptoms is often within minutes to hours some symptoms can take weeks to appear.
Because it does not significantly relieve depression of respiratory center or decrease muscarinic effects of AChE poisoning administer atropine concomitantly to block these effects of OP poisoning. Start with 1-2 g 20-40 mgkg IV in 100 mL isotonic sodium chloride over 15-30 min. Repeat in 1 h if muscle weakness is not relieved.
Then repeat q3-8h if signs of poisoning recur. Organophosphate poisoning can be short- or long-term. It can be caused by large or small doses.
The longer the exposure and the larger the dose the more toxic the effects. In some patients with mega-dose OP intoxication refractoriness to high dose atropine therapy 100-mgh with an inadequate heart rate response may be observed. In such situations the addition of small doses of an adrenergic agent eg.
Adrenaline 1-2 mcgmin improves heart rate with a dramatic reduction in atropine requirements personal observations. The lack of response to atropine may. Usual Pediatric Dose for Organophosphate Poisoning.
Children weighing over 90 pounds. 2 mg dose 40 to 90 pounds. 1 mg dose 15 to 40 pounds.
05 mg dose Less than 15 pounds. 025 mg dose bunch up thigh to provide a thicker area for injection 2 or more mild symptoms of exposure. One dose see weight guide above Severe symptoms.
One dose followed by two additional. Pralidoxime 2-PAM is given after atropine to relieve neuromuscular symptoms. 2-PAM 1 to 2 g in adults.
20 to 40 mgkg in children is given over 15 to 30 minutes IV after exposure to an organophosphate or carbamate because frequently whether the poison is an organophosphate or carbamate is unknown at the time of treatment. An infusion can be used after the bolus 8 mgkgh in. The mainstays of medical therapy in organophosphate OP poisoning include atropine pralidoxime 2-PAM and benzodiazepines eg diazepam.
Initial management must focus on adequate use of atropine. Optimizing oxygenation prior to the use of atropine is recommended to minimize the potential for dysrhythmias. Much larger doses of atropine are often needed for OP pesticide poisoning.
The definitive treatment for organophosphate poisoning is atropine which competes with acetylcholine at the muscarinic receptors. The initial dose for adults is 2 to 5 mg IV or 005 mgkg IV for children until reaching the adult dose. If the patient does not respond to the treatment double the dose every 3 to 5 minutes until respiratory secretions have cleared and there is no.
Organophosphate poisoning can occur if a person is exposed to the chemicals in high doses or over a long time. The risk of organophosphate poisoning is higher in. The fatal adult dose of Atropine is not known.
In pediatric populations 10 mg or less may be fatal. In the event of toxic overdosage a short acting barbiturate or diazepam may be given as needed to control marked excitement and convulsions. Large doses for sedation should be avoided because central depressant action may coincide with the depression occurring late in Atropine poisoning.
Each single-dose prefilled autoinjector provides a 167 mg dose of atropine base equivalent to 2 mg atropine sulfate in a self-contained unit designed for self or caregiver administration. Each 2 mg Atropine autoinjector delivers atropine in 07 mL of sterile pyrogen-free solution containing the inactive ingredients. Citric acid and sodium citrate buffer glycerin 1247 mg and phenol 28.
When recurrent use of atropine is essential in patients with coronary artery disease total dose should be restricted to 2 to 3 mg maximum 003 to 004 mgkg to avoid detrimental effects of atropine-induced tachycardia on myocardial oxygen demand. Atropine sulfate blocks the central and peripheral muscarinic receptorassociated effects of OPs. It is administered to effect in dogs and cats usually at a dosage of 022 mgkg cats at the lower end of the range every 36 hr or as often as clinical signs indicate.
For horses and pigs the dosage is 0102 mgkg IV repeated every 10 min as needed. For cattle and sheep the. Waseem Muhammad et al.
Cholinergic crisis after rodenticide poisoning The western journal of emergency medicine vol. Atropine is a muscarinic antagonist used to treat poisoning by muscarinic agents including organophosphates and other drugs. Brand Names Atnaa Atropen Busulfex Donnatal Duodote Enlon-plus Isopto Atropine Lomotil Minims Atropine Sulphate Motofen Phenohytro.
The symptoms of organophosphate poisoning include over activity of the parasympathetic nervous system. Examples of antagonists include atropine and hyoscine scopolamine which are found in the plants Atropa belladonna and Datura stramonium. Ingestion of these antagonists can cause a range of peripheral flushing dry mouth blurred vision dilated pupils tachycardia urinary retention.
Atropine should be administered every 5 to 10 minutes until secretions begin to dry up. If the military Mark I kits containing autoinjectors are available they provide the best way to administer the antidotes to healthy adults. One autoinjector automatically delivers 2 mg atropine and the other automatically delivers 600 mg 2-PAM Cl.
If the Mark I kit is unavailable or the patientvictim is.

The extent of poisoning caused by sarin depends on the amount of sarin to which a person was exposed how the person was exposed and the length of time of the exposure.
Symptoms likely will appear within a few seconds after exposure to the vapor form of sarin and within a few minutes to hours after exposure to the liquid form. All nerve agents cause their toxic effects by preventing the. The definitive treatment for organophosphate poisoning is atropine which competes with acetylcholine at the muscarinic receptors.
The initial dose for adults is 2 to 5 mg IV or 005 mgkg IV for children until reaching the adult dose. If the patient does not respond to the treatment the dose is doubled every 3 to 5 min until respiratory secretions have cleared and there is no. 275 mgkg SC qid or 13 mgkg SC IV qid for 5 days then every 2-3 days if necessary.
