|
reducing regurgitation
|
don't withhold food!!
- cannot vomit - stasis is a worry only 1 hr for guinea pigs and chinchillas - clears pharynx |
|
|
concerns pre anaesthetic
|
accept that many have underlying disease
stabilize as needed - correct fluid loss - correct nutritional balance closely monitor intake and output and WEIGHT |
|
|
pre medication
why and what |
goal is to reduce stress
- hypnorm, diazepam/midazolam, ACP and ketamine atropine to reduce salivation pre-emptive analgesia prokinetics |
|
|
injectable anaesthesia
drugs and what for |
hypnorm + diazepam or medazolam
- full GA for short procedures medetomidine + ketamine - less safe for sick animals |
|
|
induction procedure
|
sedate + anxyolytic
mask down or use volitile for deepening ET tube rarely used |
|
|
intra op management
|
active heating
pulse ox and ECG possible maintain fluid balance - bleeds |
|
|
post op pain management
|
use butorphenol to reverse phentanyl
maintain analgesia after reversal with buprenorphine maintain NSAIDs with care to nephrotoxicity |
|
|
keys to inhalation induction
|
pre-oxygenate chamber
provide non slip surface lubricate eyes first - iso is irritating use Ayer's Tpiece |
|
|
indications for neutering
|
prevents breeding
prevents sexual/territorial behavior prevents cystic ovarian disease, pyometra prevents neoplasia |
|
|
what age do rodents reach sexual maturity
|
rats and mice : 6-8 wks
hamsters : 6-8 wks, 7-14 wks for chinese gerbils : 10-12 wks guinea pigs : male 9-10 wks, female 4-6 wks chinchillas : 6-8 mos |
|
|
scrotal castration technique
|
most common - closed technique is preferred
incise over testicle ligate with transfixing/circumferential ligature - often need to remove fat pad too if open if open must ensure inguinal ring is closed |
|
|
prescrotal technique
|
2 incisions cr to each scrotum
ligate vas and vessels separately (open) close tunica with continuous close skin |
|
|
how long are males potentially fertile post castration
|
6 weeks!
|
|
|
spay technique
|
midline incision - CAREFUL of caecum
place hemostatic clamps or ligatures to ovarian vessels +/- uterine vessels if needed ligate cr to cervix |
|
|
how are chinchillas and Degus different for spays
|
no uterine body
- place transfixion ligature caudal to paired cervices |
|
|
ovariectomy guinea pig
|
<4-6 wks prevent/reduce ovarian and uterine dz
incisions through dorsolateral region - 1 cm cd to last rib bluntly dissect muscle to retroperitoneal fat - roll fat to exteriorize ovary place hemostatic clamps or ligatures proximal AND distal to ovary |
|
|
ovariectomy rats
|
<6-8 wks to prevent ovarian and uterine Dz
can use dorsal incision or dorsolateral incisionS - 1cm caudal to last rib bluntly dissect muscle to fat ligate with hemostatic clamps or ligatures - proximal AND distal to ovary |
|
|
mammary strip complications
|
EXTENSIVE mammary tissue
|
|
|
mammary neoplasia technique and Px
|
remove with as wide margins as possible
- won't be able to do full strip Px is poor - very aggressive neoplasia |
|
|
medical alternative to spaying
|
Desorelin implants
- prevent pregnancy - reduce rate of ovarian and uterine disease - reduce rate of uterine and mammary cancer |
|
|
Fracture treatment
|
callus in 7-10 days
- only require short term stabilization SEVERE fracture will tolerate external fixator cope well with amputation (supposedly they tolerate slings too...?) |
|
|
creating a splint
|
medical tape and surgical glue
medical tape and cotton bud stick or paper clip |
