What is the toxic dose of lidocaine for ruminants?

• A. 3 mg/kg
• B. 6 mg/kg
• C. 10 mg/kg
• D. 12 mg/kg

Answer: (B)

The toxic dose of lidocaine for ruminants is established at approximately 6 mg/kg. This value is derived from studies and clinical practice, which indicate that exceeding this dose can lead to toxic effects, including central nervous system and cardiovascular complications. It is crucial to adhere to this guideline when administering lidocaine to ensure the safety and well-being of ruminant animals undergoing procedures requiring anesthesia, as they can be particularly sensitive to drug toxicity.

In veterinary practice, understanding the specific dosages relevant to different species is essential for preventing adverse effects. For ruminants, doses higher than 6 mg/kg may result in significant risks, including seizures, arrhythmias, and respiratory depression. This knowledge is vital for practitioners to safeguard against accidental overdoses and to apply proper anesthetic techniques in field situations.
