Indications for Drugs ::
Induction of anesthesia.
Drug Dose ::
Intravenous Induction of anaesthesia Adult: 1-4.5 mg/kg via slow IV inj over 60 sec. A dose of 2 mg/kg produces surgical anaesthesia w/in 30 sec after inj lasting for 5-10 min. Increments of half to the full induction dose may be repeated as needed for maintenance of anesth. Alternatively, a total induction dose of 0.5-2 mg/kg via infusion, given at an appropriate rate, and maintained at a rate of 10-45 mcg/kg/min, adjusted according to response. Intramuscular Induction of anaesthesia Adult: 6.5-13 mg/kg. A dose of 10 mg/kg produces surgical anaesthesia w/in 3-4 min after inj lasting for 12-25 min. Increments of half to the full induction dose may be repeated as needed for maintenance of anesth. For diagnostic or other procedures not involving intense pain: 4 mg/kg as initial dose.
Hypertension, history of cerebrovascular accident. Eye injury, raised ocular and intracranial pressure. Psychotic disorders.
Drug Precautions ::
Minimise verbal and tactile stimulation during recovery period. Chronic alcoholic and alcohol-intoxicated patients. Preanaesthetic elevated CSF pressure. Dependence and tolerance may develop. May impair ability to drive or operate machinery. Monitor cardiac function in patients with hypertension or cardiac decompensation. Pregnancy and lactation.
Drug Side Effects ::
Emergence reactions e.g. vivid dreams, hallucinations, confusion, irrational behaviour. Increased muscle tone sometimes resembling seizures. Temporary hypertension and tachycardia. Hypotension, bradycardia, arrhythmias. Respiratory depression, apnoea, laryngospasm, diplopia, nystagmus, nausea, vomiting, lachrymation, hypersalivation, raised intraocular and CSF pressure, skin rash and pain at inj site.

Drug Mode of Action ::
Ketamine is a noncompetitive N-methyl-D-aspartate receptor antagonist that blocks glutamate. It has a direct action on the cortex and limbic system. It produces a cataleptic-like state wherein the patient is withdrawn from the surrounding environment.
Drug Interactions ::
Prolonged recovery time w/ barbiturates or narcotics. May potentiate neuromuscular blocking effects of atracurium and tubocurarine including resp depression w/ apnoea. May increase risk of bradycardia, hypotension or decreased cardiac output w/ halogenated anaesth. May potentiate CNS depression and risk of resp depression w/ CNS depressants (e.g. phenothiazines, sedating H1-blockers, skeletal muscle relaxants). May antagonise hypnotic effect of thiopental. May increase risk of HTN w/ thyroid hormones. May increase risk of hypotension w/ antihypertensive agents. Reduction in seizure threshold resulting in unpredictable extensor-type seizures when given concurrently w/ theophylline.
