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.
Dabareiner RM, White NA.A 9-year-old Thoroughbred was evaluated for clinical signs of acute abdominal pain. During laparotomy, a rent in the diaphragm and herniation of the small intestine into the thoracic cavity were detected. Because edges of the rent were smooth and fibrous, which suggested the defect was chronic, the abdomen was closed without repairing the rent. After recurrence of clinical signs, a second laparotomy was performed, during which the intestines were found to have reherniated. The diaphragmatic rent was repaired, using a polypropylene mesh secured with stainless steel staples. The horse recovered ...

Hammock PD, Freeman DE, Magid JH, Foreman JH.A 12-year old 573-kg (1,261-lb) Quarter Horse gelding was referred with colic of 12 hours' duration and with poor response to medical treatment. On the basis of physical and laboratory findings, a pelvic flexure impaction was suspected. The horse was treated medically. Because signs of mild abdominal pain persisted and the heart rate had increased, an exploratory celiotomy was performed 30 hours after signs of colic were first noticed. At surgery, the ileum was found partially entrapped within the epiploic foramen, in a left-to-right direction, to form a parietal hernia. The entrapped intestin...
Zekas LJ, Ramirez S, Brown MP.Left dorsal displacement of the large colon was diagnosed in a 3-year-old Thoroughbred gelding. Conservative treatment that included lunging after administration of phenylephrine and rolling while under general anesthesia was not successful. The displaced segment of colon was reduced surgically through a ventral midline incision, but displacement recurred 4 days after surgery. Ablation of the nephrosplenic space by suturing the nephrosplenic ligament to the splenic capsule was performed through the left flank. At followup 1 year after surgery, the horse had not had further signs of colic and h...
Stegmann GF, Jones RS.The cortisol response to anaesthesia and surgery was studied in 2 groups of horses undergoing either abdominal or non-abdominal surgery. The preoperative mean plasma cortisol concentration (pcc) of 381.7 nmol/l (s.d. 254.7) was markedly higher in the abdominal group than the early-morning mean pcc of 115.6 nmol/l (s.d. 78.4) in the non-abdominal group. During halothane anaesthesia and surgery the mean pcc increased significantly (p < 0.05) from the preoperative mean of 119.2 to 215.9 nmol/l (s.d. 79.8) after 30 min of surgery in the non-abdominal group. In the abdominal group a decrease occ...

Gaughan EM.Dental surgery is most often directed at removal of diseased or injured teeth by the least invasive method possible. Some procedures available can preserve traumatized or infected teeth. Complications of dental surgery are well documented and often encountered by veterinary surgeons. Principles of debridement, curettage, lavage and ventral drainage combined with appropriate medicinal management can reduce complications and lead to successful outcome after dental surgery.
Wittern C, Hendrickson DA, Trumble T, Wagner A.A 364-kg (800-lb) 15-month-old sexually intact cryptorchid male Quarter Horse was admitted to the veterinary teaching hospital for castration. The horse was placed in standing stocks, and a caudal epidural injection of 18 mg of detomidine hydrochloride (50 micrograms/kg [23 micrograms/lb] of body weight) was administered. Fifteen minutes after injection, the horse unexpectedly collapsed to the floor, first into sternal, and then into lateral, recumbency. Because the horse would not get up, the decision was made to perform the surgery with the horse under general anesthesia. The horse required ...
Wiemer P.In 22 stallions the surgically prepared spermatic cord was crushed and ligated. Preoperative and postoperative plasma-testosterone concentrations were measured and 60 days after surgery a HCG-stimulation test was carried out in 12 horses. In these 12 horses the testosterone production had ceased. In all 22 horses the wounds healed by primary intention. Ligation of the spermatic cord is a castration technique without surgical complications, at least in this study.
Robert MP, Stemmet GP, Smit Y.Bilateral paranasal sinus diseases are rarely reported in horses. Treatment using a bilateral frontonasal bone flap on a standing, regular-sized adult horse has not been described previously. A 13-year-old Thoroughbred gelding was evaluated for bilateral mucopurulent nasal discharge. Radiographic, endoscopic and computed tomographic examinations revealed bilateral sinus pathological changes consistent with an ethmoid haematoma involving the maxillary and frontal sinuses. A bilateral frontonasal bone flap was created under standing sedation and local anaesthesia. A tracheotomy was performed ini...
