VetalarThis treatment applies to the following species:
Ketamine Hydrochloride Injection U.s.p.
For Veterinary Use Only
DescriptionVetalar (ketamine hydrochloride) is a rapid acting, nonnarcotic, nonbarbiturate general anesthetic for cats, chemically designed 2 - (o-chlorophenyl)-2-methylamino-cyclohexanone hydrochloride. It is supplied as a slightly acid (pH 3.5-5.5) solution for intramuscular injection.
Active IngredientKetamine (as ketamine hydrochloride) 100 mg/mL.
Non-medicinal Ingredient0.01% w/v Benzethonium chloride (as preservative)
ActionVetalar is a rapid acting anesthetic producing an anesthetic state characterized by profound analgesia, normal pharyngeal-laryngeal reflexes and skeletal muscle tone, mild cardiac stimulation and some respiratory depression. The anesthesia state produced by ketamine has been termed “dissociative anesthesia” in that it appears to selectively interrupt association of the brain before producing somesthetic sensory blockade.
Following administration of recommended doses of Vetalar, blood pressure and heart rate are usually moderately and transiently increased. Respiratory rate, on the other hand, is usually decreased in cats. The pharyngeal reflexes are maintained thus aiding in the maintenance of a patent airway. Although some salivation is occasionally noted, the persistence of the swallowing reflex effectively reduces the hazards of salivation.
Other reflexes, e.g. corneal, pedal, etc., are maintained under Vetalar anesthesia, and should not be used as criteria for depth of anesthesia. Moreover, the eyes normally remain open with the pupil dilated, making it prudent to apply a bland ointment if anesthesia is to be prolonged. By single intramuscular injection in cats Vetalar has a wide margin of safety.
Following administration of recommended doses of Vetalar most cats become ataxic in about 5 minutes, and anesthesia will normally last 30 - 45 minutes. Recovery is generally smooth and uneventful, especially if animals are not stimulated by sound or handling during the recovery period. At lower doses complete recovery usually occurs in 4 - 5 hours but with higher levels of Vetalar recovery time is more prolonged and less predictable. With high levels, complete recovery may take 24 hours or more in some selected cases especially if the patient is in poor condition or suffering from nephritis.
Vetalar IndicationsVetalar is recommended as the sole anesthetic agent for diagnostic and surgical procedures. Although best suited to short procedures, it can be used, with additional doses, in procedures requiring anesthesia for periods of six hours or longer.
ContraindicationsThe use of Vetalar is not indicated in kittens under 12 weeks of age as it is not unusual in immature cats for anesthesia to be of shorter duration. Ketamine hydrochloride is contraindicated for procedures in cats requiring complete skeletal muscle relaxation.
Vetalar CautionsBecause the drug is excreted in the urine by cats, largely unchanged, caution should be exercised in dosing subjects with severe renal impairment. Caution should also be exercised in administering the drug to animals with cardio-vascular abnormalities due to its hypertensive effect in cats.
Premedication with atropine may, to some degree, deepen and prolong anesthesia in the cat.
Adverse ReactionsAt high dosage, respiratory depression may occur. If at any time cyanosis occurs, or if respiration becomes excessively depressed, resuscitative measures should be instituted promptly e.g. artificial respiration, oxygen administration, etc.
Administration And DosageVetalar is well tolerated by cats when administered by intramuscular injection.
Fasting prior to induction of anesthesia by Vetalar is not essential, however, when preparing for elective surgery it is prudent to withhold food for at least six hours prior to induction of anesthesia.
DosageAs with other general anesthetic agents, the individual response to Vetalar is somewhat varied depending upon the dose, general condition, and age of the subject so that dosage recommendations cannot be absolutely fixed.
The Following Schedule Of Dosage (base) Is Recommended
11-22 Mg/kg Body WeightMINOR SURGERY, SUTURING, ETC., MINOR DENTAL PROCEDURES, SIMPLE DIAGNOSTIC X-RAY, RESTRAINT FOR EXAMINATION (INCLUDING INTERIOR OF EYE), DRESSING, GROOMING, ETC.
