Thoracic surgery principles Flashcards
(9 cards)
small animal lung lobes
Both cats and dogs have a right lung that is subdivided into four lobes: cranial, middle, caudal, and accessory; and a left lung that is subdivided into two lobes: cranial (with cranial and caudal parts) and caudal.
thoracotomy location
between 5th and 6th ribs, that is thoracic midline
octreotide for use in ?
chylothorax
is a somatostatin analogeu that acts directly on vascular somatostatin receptors to minimize lymphatic fluid excretion.
The proposed mechanism of octreotide and somatostatin for chylothorax is that they block lymph flow in the thoracic duct through exerting effects on both splanchnic circulation and gastrointestinal motility.
low fat diet!
rutin for chylothorax?
The exact mechanism of action is unknown; however, it has been proposed that rutin reduces leakage from blood vessels, increases proteolysis and removal of protein from tissues, and enhances macrophage phagocytosis of chyle.
thoracotomy location for dogs vs cats
always 9-10th intercostal space
but in dogs, from right side (so in left lateral recumbency)
and in cats, entry from left side (so in right lateral recumbency)
how much lung can you remove from a dog or cat with survival?
40%
tolfedine indicated for?
Non-steroidal anti-inflammatory drug (NSAID) with anti-inflammatory, analgesic and antipyretic properties.
used for hyperthermia in BOAS resp. crisis
antiphlogistic = acting against inflammation or fever.
primary (3) and secondary (6) abnormalities seen in BOAS
Primary abnormalities:
* stenotic nares
* elongated soft palate
* hypoplastic trachea
Secondary abnnormalities:
* everted laryngeal saccules
* everted tonsils
* soft palate edema
* laryngeal paralysis
* tracheal collapse
* pulmonary edema
eversion of the laryngeal saccules is considered the first satge of
laryngeal collapse
they need to be surgically removed
