The impact of opioid administration on the incidence of postanaesthetic colic in horses.
Frontiers in pain research (Lausanne, Switzerland)    February 19, 2024   Volume 5 1347548 doi: 10.3389/fpain.2024.1347548
Haralambus R, Juri M, Mokry A, Jenner F.Effective management of postoperative pain is essential to ensure patient welfare, reduce morbidity and optimize recovery. Opioids are effective in managing moderate to severe pain in horses but concerns over their adverse effects on gastrointestinal (GI) motility and associated increased colic risk limit their widespread use. Studies investigating the impact of systemic opioids on both GI motility and colic incidence in horses have yielded inconclusive outcomes. Therefore, this retrospective study aims to assess the influence of systemic administration of butorphanol, morphine, and methadone ...

Passman SN, Cheetham J, Bonassar LJ, Ducharme NG, Rawlinson JJ.Upper airway obstruction is a common problem in the performance horse as the soft tissues of the larynx collapse into the airway, yet there is a paucity of information on biomechanical properties for the structural cartilage components. Objective: To measure the geometry and compressive mechanical properties of the hyaline cartilage to improve understanding of laryngeal function and morphology. Methods: A total of 11 larynges were harvested from Thoroughbred and Standardbred racehorses. During gross dissection, linear dimensions of the cricoid were obtained. From both the cricoid and arytenoid...
Surgical management of sand colic impactions in horses: a retrospective study of 41 cases.
Australian veterinary journal    October 2, 2008   Volume 86, Issue 10 404-407 doi: 10.1111/j.1751-0813.2008.00348.x
Granot N, Milgram J, Bdolah-Abram T, Shemesh I, Steinman A.A retrospective review of the medical records of 41 horses requiring abdominal surgery for sand colic. Results: The diagnosis of sand colic was made when sand was found to be the cause of impaction of the gastrointestinal tract during surgical exploration. The most common clinical signs at presentation were abdominal pain, abdominal distension and diarrhoea. A statistically significant association was found between the respiratory rate on arrival and short-term survival. Sand impaction at multiple locations was detected in one-third of the horses. Concurrent pathology was detected in half of t...
Prevalence of gastric squamous ulceration in horses with abdominal pain.
Equine veterinary journal    July 27, 2006   Volume 38, Issue 4 347-349 doi: 10.2746/042516406777749164
Dukti SA, Perkins S, Murphy J, Barr B, Boston R, Southwood LL, Bernard W.Prevalence of gastric ulcerations differs widely according to breed and circumstances of management. Further study of the biological variables involved is required in order to identify more exactly the reasons for the reported range. Objective: The objectives of this present study, which do not appear to have been addressed previously in the literature, were 1) the prevalence of gastric ulceration in horses with abdominal pain. 2) difference in prevalence in horses responding to medical therapy and those requiring surgical intervention. 3) whether gastric ulceration is associated with any part...
Enterocutaneous fistulae in horses: 18 cases (1964 to 1992).
Veterinary surgery : VS    May 1, 1994   Volume 23, Issue 3 167-171 doi: 10.1111/j.1532-950x.1994.tb00465.x
Bristol DG.Enterocutaneous fistulae are rare in horses and occur most commonly as a complication of umbilical hernias or their treatment. Horses with enterocutaneous fistulae may be successfully treated by en bloc resection of the body wall and intestine or by allowing second intention healing. Complications associated with surgical intervention include fever, colic, incisional problems, and recurrence of the fistula. Nonsurgical management of two horses with presumptive large colon fistulae resulted in resolution of the fistulae without complications.
Prognostic indicators for horses with duodenitis-proximal jejunitis. 75 horses (1985-1989).
Journal of veterinary internal medicine    November 1, 1992   Volume 6, Issue 6 307-311 doi: 10.1111/j.1939-1676.1992.tb00360.x
Seahorn TL, Cornick JL, Cohen ND.The medical records of 75 horses with duodenitis-proximal jejunitis (DPJ) were reviewed. Ages, physical parameters, laboratory values, and treatment data were compared between horses surviving DPJ and horses not surviving DPJ (Table 1). Fifty of 75 horses (66.6%) survived. Sixty-six horses (88.0%) were managed with medical treatment alone and nine horses (12.0%) were managed with medical treatment plus surgical intervention. Using a logistic regression model, the association of each of the 19 physical and laboratory parameters with death was evaluated retrospectively in the 75 horses. Three pa...
Small intestine incarceration through the epiploic foramen of the horse.
Journal of the American Veterinary Medical Association    March 15, 1984   Volume 184, Issue 6 731-734 
Turner TA, Adams SB, White NA.Fifteen horses were referred to Purdue University or to the University of Georgia because of colic. Each of these horses had small intestine incarcerated through the epiploic foramen. However, signs of pain, gastric reflux, and small intestine distention were not consistent signs, as would have been expected with small intestine strangulation/obstruction. In 10 of the 15 cases, abdominal fluid analysis provided the decisive information needed for surgical intervention. Surgery was performed in 14 cases. The small intestine was incarcerated through the epiploic foramen in a right-to-left direct...
Fractures of the central and third tarsal bones in horses.
Journal of the American Veterinary Medical Association    June 1, 1983   Volume 182, Issue 11 1234-1238 
Tulamo RM, Bramlage LR, Gabel AA.The case histories and follow-up data for 11 horses with slab fractures of the central or 3rd tarsal bones were examined for information pertaining to the diagnosis, which was difficult to identify, treatment, which was proven ineffective, and the prognosis, which was shown to be poor for return to racing. The purpose of the study was to define the results that could be obtained by nonoperative methods, in an attempt to determine whether surgical treatment was advisable. Nine of the horses were Standardbreds and 2 were Thoroughbreds; all horses were 2 to 4 years old and were being exercised at...
