Slide 4:Why ELSE would you anesthetize a rabbit???
Common surgical procedures Neutering (Gee doc, my rabbit made love to my slipper SIX TIMES last night!) Spaying (The kids have seen the miracle of life 5 times this year already!) Dental work Trichobezoars (Hairballs) Tumor removal, wound treatment, etc
Slide 5:Pre-operative considerations
Basic Husbandry Body weight, diet, caging/housing, companions To fast, or not to fast? Pre-Sx Bloodwork Serum chemistry profile +/- CBC depending on procedure Bare minimum (in our opinion): TS, PCV, Glucose Accurate weight (Duh!)
Slide 6:Possible Pre-medications & induction agents
Ketamine/Diazepam 0.2-0.5 mg/kg Diaz. IV then 10-15 mg/kg Ket. to effect. Acepromazine 0.75-1.0 mg/kg IM (No, the decimal points are NOT in the wrong place). Many other possibilities/combinations. Telazol not recommended At higher doses, can be nephrotoxic. Other possibilities: Propofol (10 mg/kg, slow bolus3-5 minutes); Thiopental; XylazineOther possibilities: Propofol (10 mg/kg, slow bolus3-5 minutes); Thiopental; Xylazine
Slide 7:Intubation
Unless rabbit is very large, intubation is blind Lidocaine splash is possible with visualization in large rabbits Most rabbits masked, not intubated Practice, practice, practice
Slide 8:Inhalant Anesthetic Agents
Isoflurane Inhalant of choice Can induce with Iso alone Induction: 3-5% Maintenance: 1.5-1.75% Halothane Induction: 3-4% Maintenance: 0.5-2% Sevoflurane To effect More expensive
Slide 9:Surgical considerations
Bain system is preferred over re-breathing system Chest elevation Temperaturemonitor frequently to avoid bunny-cicles Fluids If procedure > hour. 5-10 ml/kg/hr crystalloid fluids, add 5% dextrose Monitor as in other species (Pulse, respiration, etc) May need to use stainless steel sutures to prevent post-op complications (Remember: Rabbits chew!)
Slide 10:Post Operative Care
Keep warm, but not too warmwe arent dealing with tropical species here! QUIET!!! May or may not need to isolate from other rabbits Feed Blenderize regular pelleted feed with water. Can also be done with veggies, greens, etc Last resort: Canned, strained pumpkin (without pie spice!) Pain management Have regular favorite feeds available. Liquid feeds are mostly for a Just in case scenario. Want to prevent gastric ulcers and GI stasis.Have regular favorite feeds available. Liquid feeds are mostly for a Just in case scenario.
