Short-term survival rates of 1397 horses referred for colic from 2010 to 2018.

Background: Up-to-date and hospital-specific knowledge of prognoses for horses with various forms of colic is essential for helping to guide owners' decisions on costly treatments, and for assessing the continuous development of standards of care in the hospital. This study aimed to determine the short-term survival rates of horses admitted with colic to the University Hospital for Large Animals (UHLA), University of Copenhagen, Denmark, from 2010 to 2018, and to compare these to a previous local study as well as recent, comparable international studies. Short-term survival rates were calculated for horses grouped by treatment (surgical, medical) and diseases.

Effects of intra-articular administration of lidocaine, mepivacaine, and the preservative methyl parahydroxybenzoate on synovial fluid biomarkers of horses.

Objective: To compare the extent of inflammation and catabolic collagen response in the middle carpal joints (MCJs) of healthy horses following intra-articular injection of 2% lidocaine, 2% mepivacaine, lactated Ringer solution (LRS), or 0.1% methyl parahydroxybenzoate.

Animals: 17 adult horses.

Short-term survival and mortality rates in a retrospective study of colic in 1588 Danish horses.

Background: Outcomes of colic treatment are of great interest to clinicians, horse owners and insurers. One commonly used criterion of success is the overall short-term survival rate. This is used as to compare treatments and to measure quality of veterinary care, but may be biased by demographic or social factors such as attitudes towards animal suffering and euthanasia.

Evaluation of pain and inflammation associated with hot iron branding and microchip transponder injection in horses.

Objective: To compare effects of hot iron branding and microchip transponder injection regarding aversive behavioral reactions indicative of pain and inflammation in horses.

Animals: 7 adult horses.

Procedures: In a randomized controlled clinical crossover study, behavioral reactions to hot iron branding and microchip transponder injection were scored by 4 observers.
