Unit 3 - Neonate Renal Flashcards
True or False: Foals with spurious hypercreatinemia may be an otherwise normal foal.
True - there may be evidence of poor intrauterine life
What clinical signs are associated with spurious hypercreatinemia?
Elevated creatinine on blood work but no other signs of renal disease
Why does spurious hypercreatinemia occur?
It is the placenta’s job to clear waste and if it is not doing its job, the fetus lives in a vat of urine. Creatinine then defuses in the foal
True or False: The kidneys in foals with spurious hypercreatinemia are defective
False - they can do their job, they just need to catch up
What treatment is recommended for spurious hypercreatinemia?
Time and monitoring - if it is truly just spurious hypercreatinemia it will resolve within a couple of days
What medications can cause AKI in a foal?
NSAIDs and aminoglycosides
What causes uroperitoneum in the foal?
Rupture of the bladder (most common) or ureter or urachus - due to trauma? pressure during parturition? birth defects? urachal infection
Is uroperitoneum more common in colts or fillies?
colts
What clinical signs are associated with uroperitoneum?
Straining to urinate, lack of urine production, and lethargy
How is uroperitoneum diagnosed?
Increased hypoechoic free peritoneal fluid, serum chemistry, a comparison to serum chemistry and peritoneal fluid
What will you see on serum chemistry in a patient with uroperitoneum?
Hyponatremia and hypochloremia
Hypercreatinemia, elevated BUN, and hyperkalemia
If you have uroperitoneum, you should have a __x higher creatinine in the peritoneal fluid vs. serum.
2x
True or False: Uroperitoneum is a medical emergency.
True
What must be done prior to treatment of uroperitoneum?
Must stabilize prior to anesthesia - drain the urine, rehydrate the patient, fix abnormalities especially hyperkalemia, and antimicrobials
What can you do to identify hyperkalemia (aside from serum chemistry)?
Note bradycardia on PE and abnormal EKG (tall tented T waves, widened QRS, absent P waves, and asystole)
