20
Q

According to Boorman et al Vet Surgery 2019, what two factors were associated with non survival?
-True or false, geriatric horses were more likely to have increased volumes of reflux and not survive to discharge.

A

-long surgery times and high volume POI were associated with non-survival
-False. Age was not associated with POI or non-survival.

21
Q

“long term out come, stifle arthroscopy”

A

-cutting, western pleasure, and reining
