SURGERY OF THE LIVER Flashcards
Large, vascular, glandular, organ, Responsible for metabolism, Filter
Just behind the xiphoid
liver
indications for liver sx
tumor removal, biopsy, trauma
52% of liver surgeries
tumor removal
drug that lowers seizure threshold
acepromazine
Intravenous ___ should be avoided in dogs with liver dysfunction, because it can cause severe congestion → poor blood flow, poor oxygen perfusion → death of a lobe (would require removal of the dead lobe)
morphine
pre-op concerns for patients with impaired liver function
hepatic condition
drugs - acep,morphine, ketamine, barbiturates
sedative type
Matt’s choice for sedative
isoflurane
Safer to be given as sedative VS ketamine in liver patients
diazepam
good choice antibiotics
Penicillins, metronidazole, clindamycin
Avoid hepatotoxic antibiotics like
chloramphenicol, erythromycin, chlortetracycline
keep in mind that complcications may arise from the ff
friable tissue
sharp dissection
hemorrhage
pathogens
incision approach
cranial high, below last strenebrae
How can you remove a lobe or mass w/out causing massive bleeding if you do not have electrocautery/ cryogenic cautery?
do the guillotine technique
when doing guillotine technique, cut _mm distal to ligature
5
For non-apex/non-distal mass removal
Saves healthy tissue
Overlapping Guillotine Method
How to know if you are poking the right area?
ultrasound
smt endoscope
has High yield tissue acquisition
Get a lot of good tissue through just poking; no need to cut
non-excisional biopsies needle
