Topic:Post-Operative Period
The post-operative period in horses refers to the timeframe following surgical procedures during which the animal undergoes recovery and rehabilitation. This period involves careful monitoring and management to ensure proper healing and to minimize complications. Key aspects of the post-operative period include pain management, wound care, and the prevention of infections. Horses may require restricted movement, dietary adjustments, and regular veterinary evaluations to assess recovery progress. This page compiles peer-reviewed research studies and scholarly articles that explore the management strategies, physiological responses, and outcomes associated with the post-operative period in equine patients.

All cases were evaluated retrospectively. Follow-up information was gained via phone conversation with owners and referring vete...
Effects of corneoconjunctival transposition, posterior lamellar keratoplasty and modified deep lamellar endothelial keratoplasty on streak retinoscopy in equine cadaver eyes. Evaluate the effects of corneoconjunctival transposition (CCT), posterior lamellar keratoplasty (PLK) and modified deep lamellar endothelial keratoplasty (DLEK) on streak retinoscopy in equine cadaver eyes. Methods: Intraocular pressure (IOP) was maintained at 25 ± 3 mmHg in 35 equine cadaver eyes. Streak retinoscopy was performed prior to (NO VISCO) and following (VISCO) intracameral injection of 1.0 ml of viscoelastic. Following optical coherence tomography (OCT), an axial CCT [n = 11] or PLK [n = 12], or peripheral DLEK [n = 12] was performed. Streak retinoscopy and OCT were r...
Transillumination Techniques for Vessel Identification During Small Colon Resection in Six Horses. Transillumination has been described in human surgery to improve vessel visualization but has not been described in horses. Since the equine mesocolon contains a great amount of fat which restricts visualization of the vessels, this technique could be useful during small colon resection. To describe transillumination of the mesocolon to provide an improved vessel identification during resection and anastomosis of the small colon in horses. Data of horses that underwent resection and anastomosis of small colon were recorded. Two transillumination techniques were used during resection and anasto...
Hernia formation after single-stage umbilical vein marsupialization in three Percheron foals diagnosed with septic omphalophlebitis. Septic omphalophlebitis is a common disease process with a variety of morbidities and possible mortality. Affected umbilical remnant resection is highly successful but may not always be possible. Umbilical marsupialization can be implemented when total resection cannot be accomplished with minimally reported complications. Umbilical vein marsupialization was performed on three Percheron foals with extensive septic omphalophlebitis using the one-stage paramedian translocation technique and prolonged postoperative antimicrobial therapy. Long-term follow-up revealed herniation at the marsupializa...

Pictures were evaluated by three anaesthetists [Diplomate...
Using systemic serum amyloid A as a biomarker for synovial structure infections in horses with acute limb wounds. In postoperative monitoring of synovial structure infection due to limb wounds, early recognition of a recurrence of synovial infection is indispensable to prevent further damage to the affected synovial structure. This study evaluated the role of serum amyloid A (SAA) as a systemic biomarker in disease monitoring and correlated this tool with clinical variables. In this prospective cohort study, 55 horses with acute limb wounds were divided into two groups: those with (group 1, n = 26) or without (group 2, n = 29) a diagnosis of synovial structure penetration. SAA, lameness and body tempe...

Percutaneous Ultrasound-Guided Carotid Access and Puncture Closure with Angio-Seal in Horses. There are different indications for endovascular surgery in horses, mainly the treatment of guttural pouch mycosis. Traditionally, these procedures are carried out by open arteriotomy of the common carotid artery (CCA), although less invasive percutaneous ultrasound-guided carotid access (PUGCA) has been described in experimental horses. In human medicine, commercial closure systems are used to seal these arterial puncture sites and reduce complications. The aims of this study are to retrospectively describe our experience with PUGCA in clinical cases and to report, for the first time, the us...

Unilateral, Rostral Maxillary Sinusitis Resulting from Displacement and Retention of an Alveolar Plug in a 4-Year-Old Horse. Sinusitis is a common occurrence in horses and often develops secondary to dental disease. Extraction of cheek teeth in horses is associated with variable degrees of complications and although postoperative displacement and retention of alveolar plugs has been identified as one such potential complication, few cases of resulting sinusitis have been reported. This manuscript describes a four-year-old Thoroughbred mare that was presented for chronic unilateral left-sided mucopurulent nasal discharge after extraction of the left maxillary second molar tooth two months earlier. Radiographic and co...
Predictive Models for Equine Emergency Exploratory Laparotomy in Spain: Pre-, Intra-, and Post-Operative-Mortality-Associated Factors. The extrinsic and intrinsic characteristics of an equine population may influence the onset of gastrointestinal lesions and affect the survival rate of patients. The equine population in Spain has been the focus of a small number of studies, none of which have involved more than one surgical center. In this retrospective cohort study, we aimed to analyze the survival rate, identify the variables that influenced death, and generate multivariate models using clinical variables. Data were collected from the clinical records of two surgical referral centers in the same region, and a total of 566 h...

Strangulating left colon volvulus following nonsurgical castration in a 6-year-old donkey. Colic is a clinical syndrome and has been defined as a visceral abdominal pain and/or acute abdominal disease. It is a common cause of morbidity and mortality in horses. The most common forms of colics are related to gastrointestinal tract in nature and most often linked to colonic disturbances. However, colics are not well understood in donkeys compared to those of in horses and the literature is poor regarding bowel strangulating obstruction in donkeys. This report described the clinical signs and post-mortem necropsy findings of an abdominal colic due to the left colon volvulus following a ...
