Guaifenesin alone or in combination with ketamine or sodium pentobarbital as an anesthetic in rabbits.
Guaifenesin was administered alone and in combination with ketamine or sodium pentobarbital to adult New Zealand white rabbits. A solution of 5% guaifenesin in 5% dextrose given intravenously at a dosage of 200 mg/kg, abolished the pedal, palpebral and corneal reflexes for up to 15 minutes with little influence on cardiopulmonary function. Guaifenesin (200 mg/kg, intravenously) and ketamine (50 mg/kg, intramuscularly) produced effective and safe surgical anesthesia for over 30 minutes. This combination mildly depressed respiratory rate but heart rate and arterial blood pressure were not significantly affected. Guaifenesin (200 mg/kg, intravenously) was combined with sodium pentobarbital (20 mg/kg, intravenously) to produce surgical anesthesia for a period of more than 30 minutes. This combination depressed respiratory rate, produced a tachycardia and decreased arterial blood pressure.
