Common toxicities in animals

Emergency toxicities in animals are commonly encountered in veterinary practice due to frequent exposure to toxic substances present in households, feed, medications, and the environment. Anti-nutritional factors (ANFs) such as trypsin inhibitors, thiaminase, gossypol, and cyanogenic glycosides are important contributors to toxicity, often requiring specific detoxification methods including heat treatment, vitamin supplementation, or chemical neutralization. Effective management of poisoned animals relies on rapid history taking, including identification of the toxicant, dose, and time of exposure, followed by prompt clinical assessment using the ABCD approach. Clinical signs may range from mild gastrointestinal disturbances to severe neurological, cardiovascular, and respiratory complications, including seizures, arrhythmias, hypoxia, and coma. Diagnosis is primarily based on history, clinical findings, and laboratory investigations. Treatment strategies focus on stabilization through fluid therapy, gastrointestinal decontamination, and supportive care. Decontamination techniques such as emesis, gastric lavage, and activated charcoal play a crucial role in limiting toxin absorption. Supportive therapies, including beta-blockers, vitamin K₁, hepatoprotective agents, and anticonvulsants, are used based on clinical presentation. Although specific antidotes are limited, agents such as fomepizole, 2-PAM, and naloxone may be utilized in selected cases. Early intervention and comprehensive management are essential to improve clinical outcomes.
