Objective:
To report the use of caffeine as a respiratory stimulant in a cat with hypoventilation.
Case Summary:
A cat was mechanically ventilated due to persistent hypercapnia (Pet co2 > 75 mm Hg) following median sternotomy and thymectomy. After 3 days of mechanical ventilatory support, the cat would initiate breaths but failed weaning due to persistent hypercapnia. Following administration of intravenous caffeine (total 12 mg/kg over 24 h), respiratory and mental status rapidly improved. The cat was subsequently extubated and able to maintain Pvco2 < 50 mm Hg. The cat was later diagnosed with myasthenia gravis. Quality of life 13 months after discharge was reported as excellent by her owner.
New Or Unique Information Provided:
Caffeine may be considered as a respiratory stimulant in cats with hypoventilation.

Adrenergic Agonists: Mixed-Action Agents
Ephedrine and pseudoephedrine lack a catecholamine group, making them less susceptible to degradation by metabolic enzymes. They have increased oral bioavailability and lipophilicity, resulting in a longer duration of action. Their response is reduced by...
Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by...
Adrenergic Agonists: Therapeutic Classification
Vasopressor or pressor agents: They increase blood pressure and function as cardiac stimulants. Examples include endogenous catecholamines (norepinephrine and dopamine) and synthetic agents (phenylephrine).
Bronchodilators: β2-agonists can relax bronchial muscles and widen airways. They are commonly used for treating obstructive pulmonary...
Adrenergic Agonists: Therapeutic Uses
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.

Cocaine can be administered via snorting, injection, or smoking. It primarily functions by blocking the reuptake of dopamine, resulting in a euphoric high characterized by an intense sensation of happiness and...
