Health Tips
The fist HEALTH TIP 1 article was published in a recent Tibetan Spaniel Club of America Newsletter:
Since the first health tip was published Dr. Hartman has switched to a new gas anesthetic called
Sevoflurane and has used it on Tibbies with great success. Although this new gas is more costly
it is safe and has the fastest recovery time yet. I witnessed my own Tibbies up on their feet and
running around just 20 minutes after a procedure with no side affects.
HEALTH TIP 2
Sevoflurane Anesthetic Protocol for Tibetan Spaniels
By Dr. Lewis R. Hartman
Mask with 6% to 6.5% Sevoflurane concentration with 2 Liter OXYGEN flow until deep enough
anesthetic plane to intubate.
After intubation maintain at 3.0 to 3.5% Sevo (Sevoflurane) concentration at 1.5 to 2 liter oxygen flow.
Recovery starts within a few minutes after Sevo is discontinued.
I have used Sevoflurane with out the need for pre-anesthetics since it is not irritating and well
tolerated. However using a pre-anesthetic can shorten the masking time. Torbugesic at .2 to
.3 mg/kg combined with glycopyrrolate at 0.015mg/kg is a suitable and safe pre-anesthetic
protocol with the additional advantage of having an analgesic benefit.
However if your veterinarian does not have this new anesthetic available here is a safe protocol for Tibetan Spaniels. As you may or may not know Tibbies are very sensitive to anesthetic and can have difficulties if precautions are not taken.
HEALTH TIP 1
Anesthetic Protocol for Tibetan Spaniels
By Dr. Lewis R. Hartman
This protocol will be most helpful for first time Tibbie owners and their Veterinarians who have limited experience with the Breed.
Many of you have “Tibbie experienced” Veterinarians, who have developed their own anesthetic protocols. I welcome their inputs and participation. They can send their favorite protocols to me at LRHMDH@aol.com.
Tibetan Spaniel Anesthetic Protocol
Pre-Anesthetic:
.015 mg/kg glycopyrrolate (Robinul) IM
.01 mg/kg medetomidine ( Domitor ) IM 15 to 20 minutes later (option of giving at same time)
Wait 40 minutes after Domitor injection to start Induction
Induction:
IV Diazepam/Ketamine (1:2 ratio) given slowly to effect until able to intubate (.75 to 1.0 ml/10 lbs. )
Option of Isoflurane/ O2 mask (3% Isoflurane with 2 liter O2 flow)
Maintenance Anesthesia:
Initial 1% Isoflurane with 1 liter O2 flow rate gradually reduce to 0.5% to 0.25% Isoflurane
Use a Non-Rebreathing system
Anesthetic Monitoring:
Pulse Oximeter mandatory with ECG monitoring preferred
Comments:
Domitor as a pre-anesthetic enables the use of much lower Isoflurane concentrations during maintenance anesthesia
The reversibility of Domitor with atipamizole ( Anisedan ) enables quick recovery if needed
Domitor as an analgesic is also an advantage
This protocol is most suited for the young to middle-age Tibbie
HIGHER RISK PATIENTS (Geriatric)
Butorphanol (Torbutrol) 0.2 mg/kg IM as a pre-anesthetic
Isoflurane/O2 mask Induction
Isoflurane maintenance anesthesia
CAUTION:
With extended anesthesia time a DECREASED PULMONARY TIDAL VOLUME is often seen. This occurs even when the Respiratory Rate is normal. This is why Pulse Oximeter monitoring is absolutely necessary. Assisted Ventilation by bagging two to three times per minute will prevent this from happening. Also maintain O2 blood levels above 92% with Ventilation.
