Medical records in relation to horses are systematic documentation of a horse's medical history, treatments, and health-related events. They encompass a variety of information, including vaccination records, clinical examinations, diagnostic test results, treatments administered, surgical procedures, and any ongoing health issues. These records are maintained by veterinarians and are utilized to track the health status and medical history of individual horses. They provide valuable data for monitoring the progression of diseases, assessing treatment outcomes, and making informed decisions regarding future healthcare. This page compiles peer-reviewed research studies and scholarly articles that explore the management, accuracy, and application of medical records in equine veterinary practice.

Results: Five of 37 horses (14%) developed transient signs of Horner's syndrome postoperatively. Obvious clinical signs began 2 to 5 h following local anesthesia and persisted for two to 4 h. Profuse un...
Anderson SL, Blackford JT, Kelmer SG.This study describes the outcome and complications in horses that had a closed, one-stage, stapled, functional, end-to-end (COSFE) jejuno-ileal anastomosis (JIA) following resection of compromised small intestine. Medical records were reviewed to identify all horses that had a COSFE JIA performed during exploratory laparotomy and to determine post-operative complications and final outcome. All 5 horses that were identified had successful COSFE JIA with resection of various amounts of distal jejunum and proximal ileum. Post-operative ileus occurred in 1 of the 5 horses. All horses survived at l...
Rosser J, Brounts S, Slone D, Lynch T, Livesey M, Hughes F, Clark C.Our objective was to compare survival and complication rates of horses undergoing pelvic flexure enterotomy closure with a TA-90 stapler to those with hand-sewn closure. Medical records of horses undergoing pelvic flexure enterotomy between 2001 and 2008 were reviewed. History, clinical signs, surgical findings, surgical techniques, and post-operative complications were recorded. Long-term outcome was established by telephone questionnaire. Of 84 pelvic flexure enterotomies performed, 70 were stapled and 14 were hand-sewn. Seventy-seven horses survived to discharge (91.7%). There were no signi...
Fairburn AJ, Sherlock CE, Mair TS.Radiography is a standard diagnostic test for horses with suspected fractures of the palmar/plantar processes (PP) of the distal phalanx, however published studies evaluating the diagnostic utility for radiography are currently lacking. The objectives of this retrospective, diagnostic case-control study were to determine the sensitivity of radiographs for the detection of PP fractures, and determine the diagnostic utility of the palmar/plantar oblique projections of the PP for the identification of PP fractures compared to standard radiographic series. The medical records of horses undergoing...
