[Acceleration of the restoration of conditioned reflexes following anesthesia using aminostigmine]. / Uskorenie vosstanovleniia uslovnykh refleksov posle narkoza ketaminom s pomoshch'iu aminostigmina.

The effect of anesthesia with ketamine (80 mg/kg, intraperitoneally) combined with phenazepam (0.5 mg/kg, subcutaneously) on the reproduction of an elaborated active avoidance reflex in automated reflexometer has been studied on random bred white rats. In has been shown that during 3 hours after the animal is taken out of the lateral position the degree of its learning is significantly lowered and does not return to baseline even a day later. Intramuscular administration of a new cholinesterase inhibitor aminostigmine right after the end of anesthesia restores the disrupted reflex in 3 hours. The optimal antistigmine dose is 0.015 mg/kg, which corresponds to a therapeutic human dose.
