1) RECOMMENDATIONS
a) General Approach
i) Avoid agents that depend on redistribution to body fat for recovery
ii) Effectively control patient anxiety
b) Pre-anesthetic Medications
i) Opioids combined with a benzodiazepine form an effective preanesthetic
base
(1) Add acepromazine or (dex)medetomidine to improve anxiolysis and relaxation
c) Induction
i) Propofol and alfaxalone are very effective induction agents generally associated with smooth
recoveries
ii) Ketamine/Valium is a reasonable option
iii) Opioid/benzodiazepine induction is another option
(1) Recovery may be prolonged – reversal agents can be employed if
needed to facilitate recovery
iv) Methohexital is the only recommended thiobarbiturate for sighthound
induction
(1) It does not require redistribution for recovery
(2) Recovery is through agent metabolism which sighthounds handle
adequately
(3) Thiopental can be used in sighthounds but its use is not
recommended as the therapeutic index is uncomfortably narrow
d) Maintenance
i) Isoflurane or sevoflurane
e) Support
i) Carefully monitor patient temperature
ii) Be prepared to administer additional sedative/tranquilizer at extubation to avoid rough recoveries
2) PRECAUTIONS
a) Pre-anesthetic Medications
i) Avoid preanesthetic combinations that lack effective sedation
b) Induction
i) Avoid thiobarbiturates other than methohexital
c) Maintenance
i) N/A
d) Support
i) Monitor body temperature – sighthounds are prone to hyperthermia if the perianesthetic experience is stressful |
