Between 2000 and 2012, there was no change in the incidence of PORV for dogs undergoing neurologic, orthopedic, and soft tissue surgical procedures; however, the proportion of dogs that regurgitated increased significantly in 2012. Preoperative antiemetic prophylaxis should be considered in dogs undergoing gastrointestinal surgery and in those in which other risk factors are present.

Previous work demonstrated renal fibrosis 70 days after a single unilateral in vivo renal ischemic event, but changes associated with a single episode of renal ischemia past this time are unknown. In this study, we evaluated renal function and structural changes 6 months after a 90-minute in vivo unilateral renal ischemic event. Six adult female cats underwent unilateral renal ischemia and renal function was followed for 6 months, at which time the kidneys were evaluated by histology and histomorphometry. Over time, there was a significant reduction in the glomerular filtration rate and an elevation of serum creatinine of 31% and 42%, respectively. All cats had tubulointerstitial lesions characterized by segmental interstitial inflammation, tubular atrophy, and interstitial fibrosis. Unlike short-term studies, ischemic kidneys had variable numbers of obsolescent glomeruli, consistent with the development of atubular glomeruli and subsequent ischemic glomerulosclerosis. Chronic changes associated with acute renal ischemia may include loss of function and glomerulosclerosis.

The purpose of this study was to evaluate owner perception of outcome following permanent tracheostomy (PT) in dogs. Medical records of dogs who received PT from 2002 to 2016 were reviewed. A questionnaire was given to owners verbally or by e-mail to ascertain their perception of their dog's outcome after PT. Median time to questionnaire administration from PT surgery was 608 days (64-3,708). Owner satisfaction after PT was high (89.7%), with the majority stating they would have the procedure performed again (79.5%). Owners reported an improvement in their dog's personality (30.8%) and increased activity (41%). Median survival time was 1,825 days (64-2,663), with 6 of 39 dogs (15.4%) alive at study end. Of the 33 dogs who died, 11 (33.3%) died from underlying respiratory conditions suspected to be related to the PT. The overall complication rate was 82.1%, with mucus secretion being the most common. Revision surgery was required in 30.8% of dogs (most commonly due to skin occlusion), and aspiration pneumonia occurred in 17.9% of dogs. Overall, owner satisfaction after PT in dogs is high despite intensive postoperative management, and long survival times can be achieved.
