Q

Pathogenesis of Bladder rupture

A

milk is high in K and low in NaCl –> kidneys conserve Na/Cl –> urine is highK and low Na/Cl.
rupture - into abdomen –> Na/Cl from plasma goes into peritoneum, K from peritoneum goes into plasma

This causes the lab results

Q

Diagnostic tests for Bladder rupture and what we look for…

A

Abdominocentesis –> periton creatinine:plasma creatinine ratio is 2:1 or higher

NMB test - catheter this stuff, then do the abdominocentesis

rads - fluid and positive contrast
U/S - free fluid

A

narrow and long urethra

pressure urachus

Q

What are the muscle layers of the equine bladder?

A

Everywhere - IC, OL (like the gut)

Dorsal - inner long, outer circular

18
Q

What about Bladder rupture animals makes them bad for surgery?

A
  1. HyperK - arrythmias, AV conduction dist.
  2. HypoNa - potentiates the HyperK effects
