Every held source for this drug and species, as printed. Where they differ, both are shown — the choice is yours, not ours.
The sources disagree for this combination. The ranges below do not overlap on a comparable route. This is not an error in one of them — published veterinary references differ, and reconciling them for a particular patient is a clinical judgement.

NMDA receptor antagonist producing dissociative anesthesia. Provides somatic analgesia, amnesia, and catalepsy while maintaining pharyngeal reflexes.
Increases intracranial and intraocular pressure. Causes increased salivation (premedicate with anticholinergic). Eyes remain open under anesthesia — use lubricant. Do NOT use alone in dogs/cats (muscle rigidity) — combine with a sedative.
Species-specific contraindications and adverse-reaction reports for blue-tongue skinks may differ from canine / feline reference data — consult the primary citations listed with each rule.
Ketamine dose ranges in blue-tongue skinks, with cited source references: IM 5–10 mg/kg once; SC, IM 30–50 mg/kg not stated in source. Reference ranges from cited sources — verify against current literature before clinical use.
Documented routes for Ketamine in blue-tongue skinks: IM, SC, IM.
Ketamine is indicated in blue-tongue skinks for: Reduce breath-holding during chamber induction, Sedation.
These are general warnings for Ketamine across species; consult the blue-tongue skink dosing table above for species-specific guidance. Increases intracranial and intraocular pressure. Causes increased salivation (premedicate with anticholinergic). Eyes remain open under anesthesia — use lubricant. Do NOT use alone in dogs/cats (muscle rigidity) — combine with a sedative.
Why a species-specific page? Ketamine pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in blue-tongue skinks — the rules above are the citations specific to this species, not generic recommendations.
