Emergency Guide: Treating Organic Phosphorus Poisoning
When a cat is poisoned, it often exhibits a profound sense of depression and weakness, lying motionless on the ground. Symptoms may include excessive drooling and tearing, constricted pupils, and pale, cyanotic mucous membranes. The cat may also vomit continuously, with the vomit appearing dark purple and emitting a strong odor of the pesticide diazinon. The facial muscles may lose elasticity, leading to muscle paralysis. The poisoned cat may lie on the ground with its limbs moving in a swimminglike motion. Distinct muscarinic and nicotinic symptoms are also apparent.
Immediate treatment is crucial:
Firstly, it is essential to quickly remove the toxic substance. Before administering any medication, it is vital to eliminate the poison from the cat's body: promptly induce vomiting and perform gastric lavage, as well as administer a purge and rinse the fur with water to reduce further absorption of the toxic substances.
Vomiting can be induced using a 1% copper sulfate solution, administered orally at a dose of 100 mL per cat. After the cat has vomited, wash the stomach with physiological saline and a 2% sodium bicarbonate solution, repeating the process 2 to 3 times. For purging, administer sodium sulfate at a dose of 0.6 g/kg of body weight, and thoroughly rinse the cat's mouth, nose, and fur with soap and water.
Once the toxic substances have been removed, it is important to administer specific antidotes for解毒. Commonly used antidotes for organophosphate poisoning include cholinesterase reactivators and anticholinergic drugs. During treatment, use pralidoxime iodide, with a dosage of 30 mg per kilogram of body weight, diluted in physiological saline to a 2.5% concentration and administered slowly via intravenous injection. Repeat the injection every 2 hours, with a total dose of 15 mg until the symptoms improve.
Subsequently, administer atropine sulfate, with an initial dose of 0.5 mg per kilogram of body weight, administered subcutaneously. Repeat the injection after 2 hours. Throughout the detoxification process, ensure the cat maintains fluid balance by administering physiological saline and 10% glucose solution intravenously, 100 mL twice daily, in the morning and afternoon.
Additionally, pay close attention to the cat's respiratory function, ensuring it breathes comfortably. If the cat experiences difficulty breathing, provide oxygen immediately and strengthen the nursing care during treatment to minimize the impact of the organophosphate pesticide on the cat.
