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.
Standing abdominal surgery. Safe, effective surgery can be performed in the standing, conscious horse using a combination of mechanical and chemical restraint. Clear indications for performing standing abdominal surgery exist, but many procedures are best performed under general anesthesia. The preferred approach involves a modified grid incision of the left paralumbar fossa. Flank celiotomy allows the surgeon to thoroughly explore the abdominal cavity, but few structures can be exteriorized, and visibility of abdominal contents is poor. Indications for standing abdominal surgery include diagnosis of abdominal masses, dr...
Rostral mandibulectomy in five horses. Rostral mandibulectomy with primary gingival closure was performed in 5 horses with rapidly growing or bleeding mandibular tumors. The technique involved preservation of the most caudal portion of the mandibular symphysis to maintain stability. There were no surgical complications or recurrences, and the cosmetic and functional results were good. The histopathologic diagnosis of all the tumors was ossifying fibroma. Rostral mandibulectomy affords a simple and effective technique of treating tumors of the rostral portion of the mandible in horses.
Multivariable prediction model for the need for surgery in horses with colic. A survey of 1,965 equine colic cases was conducted from August 1985 to July 1986 at 10 equine referral centers located throughout the United States. The purpose of this study was to develop and validate a multivariable model for the need for surgery. Two-thirds of the cases were randomly selected for model development (1,336), whereas the remaining cases (629) were used only for subsequent validation of the model. If a lesion requiring surgical correction was found at either surgery or necropsy, the case for the horse was classified as surgical, otherwise the case was classified as medical. On...
[Adenoma of the pigmented epithelium of the iris with endothelialization and descemetization in the horse]. The authors describe peculiar tumors with brown-white piebald anterior surface, which had grown bilaterally from the corpora nigra (C.N.) of an adult horse and occluded the pupils. The surgical procedure for removing the larger tumor and the postoperative treatment are described. The findings by light and electron microscopy suggest that the tumor represent a so-called adenoma of the iris pigment epithelium. The white patches on its surface consist of newly formed Descemet-like material produced by displaced corneal endothelial cells, which have probably grown on the tumor after contact with t...
Femoral head ostectomy in horses and cattle. Femoral head ostectomy was performed in six horses, three ponies, and four cattle for treatment of fractures of the femoral capital physis, coxofemoral luxation, fractured acetabulum, or severe degenerative joint disease. The procedures were performed via a cranial approach that did not involve osteotomy of the greater trochanter. A dorsal approach for femoral head ostectomy via osteotomy of the greater trochanter was evaluated in three healthy adult ponies. Three animals (2 ponies, 1 calf) were euthanatized within a month and one horse was euthanatized at year 2 due to postoperative complicat...
[Postanesthetic complications in the horse. Evaluation of anesthesia in the last 28 years (1962-1989)]. The anesthesia routine in the horse is briefly explained. 35 postanesthetic complications resulted from the total of 4364 cases of anesthesia. They are evaluated by means of the duration of anesthesia, the time of paresis, the exemplary courses of enzymes as well as the distribution of race and sex and their ratio towards all cases of anesthesia. Finally a list of demands concerning the operative and postoperative phases is compiled to minimize postoperative myositis (PAM) and lameness (PAL).
T-plate repair of fracture of the nasal bones in a horse. A 5-hole T-plate was used to repair an unstable compound depression fracture of the nasal bones in a horse. Substantial bone loss was evident as a result of severe trauma. Satisfactory bone healing, facial contour, and airway function were achieved. The use of a T-plate can be an alternative means of repair of a nasal bone fracture in a situation in which instability and/or bone loss exists.
Leiomyoma of the small colon in a horse. A leiomyoma of the small colon was discovered incidentally in a 4-year-old Thoroughbred gelding during colic surgery to correct large colon displacement. The mass and 20 cm of small colon were resected, and an end-to-end anastomosis was performed. A postoperative fecal impaction proximal to the anastomosis responded after 5 days to administration of intravenous fluids, analgesics, and stool softeners.
Surgical repair of an intrathoracic esophageal pulsion diverticulum in a horse. An intrathoracic esophageal pulsion diverticulum causing repeated episodes of esophageal obstruction in a Morgan weanling colt was diagnosed by endoscopy, positive contrast radiography, and pleuroscopy. Surgical excision of the diverticulum alleviated clinical signs, and the horse was able to resume a normal diet by day 6. After 9 months the colt remains asymptomatic.
Lag screw and cancellous bone graft fixation of transverse proximal sesamoid bone fractures in horses: 25 cases (1983-1989). Case records of 25 horses with transverse fractures of the proximal sesamoid bone were reviewed to evaluate the success of treatment. All fractures were repaired by use of lag screw fixation and an autogenous cancellous bone graft because the fracture fragments were considered too large for surgical removal and reconstruction of the suspensory apparatus was necessary. Radiography was performed in all cases, and the fractures were classified into 3 types: (1) proximal midbody fractures, which included all fractures in the proximal aspect of the sesamoid bone that resulted in fragments involving...
Racing performance of Thoroughbred horses after arthroscopic surgery of the carpus. The case record, and subsequent racing performance, of 110 horses that had undergone arthroscopic surgery of the carpus, were reviewed. Of these, 87% resumed racing, with 43% able to win at least one race, after surgery. Horses with chip fractures from the distal radius had the best prognosis, while horses with sagittal fractures of the third carpal bone had the poorest. The performance of horses with bilateral lesions was similar to those with unilateral lesions. It was concluded that arthroscopic surgery was a suitable technique for the diagnosis and treatment of carpal lesions in the horse....
Types of colic and frequency of postcolic abortion in pregnant mares: 105 cases (1984-1988). The records of 105 pregnant mares and 105 nonpregnant horses with colic admitted to an equine hospital were reviewed. The 2 groups had similar types of colic and short-term survivability. Of the 105 pregnant mares, 31 were treated medically and 74 required surgical intervention. Thirty-three of the 105 mares died or were euthanatized. Thirteen (18%) of the 72 remaining mares aborted. Of 4 mares with severe medical cases, 2 died, 1 aborted, and 1 aborted and died. Of 27 horses with medical cases that required less intensive treatment, none died and 2 aborted. Of the 74 horses that required surg...
Repair of an open radial fracture in an adult horse. An open radial fracture in an adult horse (450 kg) was repaired by internal fixation, using two 18-hole 4.5-mm broad dynamic compression plates and 5.5- and 4.5-mm bone screws. The fracture healed completely, but when evaluated 9 months after surgery, the horse was lame on the fractured limb at a trot. Local infiltration of anesthesia along the distal half of the bone plates greatly ameliorated the lameness, suggesting that the plates were irritating the soft tissues and extensor tendons along the cranial and lateral aspects of the antebrachium. Both bone plates were removed simultaneously wit...
[Stomach ulcers in the horse–clinical and gastroscopic findings in 12 horses (1989-1990)]. Twelve horses with clinical symptoms of a gastric disorder were studied by gastroscopy. Symptoms of gastric disorders were periprandial colic, bruxism, ructus and reflux. Preliminary to gastroscopy the horses were fasted for 24 h. Access to water was not restricted. The gastroscopy could be conducted easily using a fiberscope 2.5 m in length and 11 mm in outer diameter. While ulcers were present in the squamous fundus of all horses only one horse showed ulceration of the glandular fundus. Solitary ulcers near the margo plicatus were found in horses with mild clinical symptoms. In contrast, dif...
Surgical correction of strictures of the large colon in three horses. An extensive stricture of the left dorsal colon in a Thoroughbred colt was resected and the colon was anastomosed. In two horses, circumferential strictures at the pelvic flexure 2.5 to 3 cm long were corrected with a modified Heineke-Mikulicz pyloroplasty technique. The horses were reported to be doing well at 6, 8, and 45 months, respectively.
Effects of exploratory laparotomy on plasma and peritoneal coagulation/fibrinolysis in horses. Plasma and peritoneal fluid samples were collected before and after surgery from 6 horses undergoing a ventral midline exploratory laparotomy and from 6 anesthetized control horses. Coagulation/fibrinolytic components measured in the plasma and peritoneal fluid of these horses included the functional activity of antithrombin III, alpha-2 antiplasmin, plasminogen, and protein C, and the concentrations of fibrinogen and fibrin degradation products. Peritoneal fluid antithrombin III, fibrin degradation products, and plasminogen values were significantly increased after surgery (over time) in prin...
Surgical treatment of open splint bone fractures in 26 horses. Over a period of 16 years, 26 horses were treated for open fractures involving the splint bones. Treatment consisted of surgical excision of fracture fragments and sequestra, and curettage of infected and unhealthy tissues. The splint bone distal to the fracture was removed in nine horses in which the attachment of the splint bone to the cannon bone via the interosseous ligament did not provide adequate stability. In two horses it was considered necessary to stabilise the proximal fragment by internal fixation and infection developed in both of them; one of these horses was destroyed on humane...
Resection of a cervical tracheal bronchus in a foal. A 3-day-old Thoroughbred foal developed a large, air-distended, midcervical swelling that was diagnosed as a congenital tracheal bronchus with associated ectopic lung tissue. Clinical signs consisted of a compressible air-filled sac that enveloped the trachea. The nature and extent of the defect were evaluated endoscopically and radiographically. Surgical resection of the bronchus and associated air-filled sac resulted in a functionally and cosmetically acceptable outcome.
Eltenac, a new anti-inflammatory and analgesic drug for horses: clinical aspects. Two controlled studies to determine efficacy in the horse were performed with eltenac, a new injectable, non-steroidal anti-inflammatory drug (NSAID). Clinical trials were carried out with a dose rate of 1 mg/kg body weight in a randomized, placebo-controlled, double-blind design to assess therapeutic efficacy in acute inflammatory disorders and in animals with orthopaedic conditions. In a preliminary pharmacokinetic investigation in six horses mean elimination half-life was 1.7 h after i.v. administration. In the first clinical study, analgesic activity on pain-related lameness was determined...
Cosmetic repair of a facial deformity by use of a silicone implant in a horse. A heat-vulcanized silicone implant was used for cosmetic repair of a facial deformity in a horse. The deformity had resulted from fracture of the frontal bone into the frontal sinus 6 months earlier. Normal facial contour was restored by suturing the sculpted implant to the periosteum over the defect. Results 1 year after surgery were excellent.
Use of transendoscopic contact neodymium:yttrium aluminum garnet laser to drain dorsal epiglottic abscesses in two horses. A submucosal abscess, located on the dorsal surface of the epiglottis, was diagnosed in 2 Thoroughbred racehorses by use of endoscopy. Both horses had exercise intolerance. One horse had intermittent dorsal displacement of the soft palate, coughed while eating and galloping, and made an abnormal respiratory noise. Both abscesses were drained transendoscopically by use of a contact neodymium:yttrium aluminum garnet laser. Eleven days after surgery, the surgical sites appeared to have healed. Clinical signs resolved permanently, and both horses returned to successful racing careers.
Use of phacofragmentation for cataract removal in horses: 12 cases (1985-1989). The medical records of 12 horses that had cataracts removed by use of phacofragmentation were reviewed. Cataracts were removed from 16 eyes in horses ranging in age from 2 months to 15 years. Complications after surgery included corneal ulcers in 13 eyes, diffuse corneal edema in 5 eyes, and uncontrollable uveitis in 3 eyes. Follow-up information was obtained in all horses from 1 month to 3.5 years after surgery. Visual results were judged good by owners or veterinarians in 10 of the horses.
Arthroscopic removal of osteochondral fragments of the palmar/plantar aspect of the metacarpo/metatarsophalangeal joints. This paper presents the results of arthroscopic surgery in 42 Standardbred trotters and three Finnish horses. Forty-five horses were operated on. The age range was one to seven years; 73 per cent of the horses were three years old or younger. Horses showed a variety of clinical signs ranging from moderate to severe lameness at slow speeds, to obscure lameness manifesting only at high speeds. Synovial effusion of the fetlock joint was rare. In this series, 44 horses that had Type I fragments and one horse that had Type III fragments were operated on. Of the 45 horses operated on, 23 (51 per cen...
Evaluation of peroral transendoscopic contact neodymium:yttrium aluminum garnet laser and snare excision of subepiglottic cysts in horses. Three basic techniques (and one modified technique) were developed, allowing successful excision of subepiglottic cysts in 10 horses (5 Standardbreds, 4 Thoroughbreds, and 1 Quarter Horse; mean age, 3.5 years) via peroral approach. This approach eliminated the need for laryngotomy or pharyngotomy and reduced postoperative care. None of the cysts redeveloped. Clinical signs of disease before surgery included respiratory noise, exercise intolerance, coughing, and dysphagia and were eliminated in all horses except one that raced successfully, but in which some respiratory noise was detected. Pero...
Osteochondritis dissecans of the tarsocrural joint: results of treatment with arthroscopic surgery. The technique and results of arthroscopic surgery for the treatment of osteochondritis dissecans in 318 tarsocrural joints in 225 horses are reported. Of the 225 horses, 154 were racehorses or intended for racing. Arthroscopic surgery was an effective technique for treating osteochondritis dissecans of the tarsocrural joint. The overall functional ability and cosmetic appearance of the limbs were excellent. Post surgical follow-up information was obtained for 183 horses, of which 140 (76.5 per cent) raced successfully or performed their intended use following surgery. Of the remaining 43, 11 w...
Idiopathic cecal rupture in foals after anesthesia for gastric endoscopy. Cecal rupture has been reported as a complication of tape-worm infestation or parturition in horses. Often it occurs with no apparent predisposing factors. Spontaneous rupture on the medial surface of the cecum occurred in 2 of 19 foals, 12 to 24 hours after gastric endoscopy. The sites of rupture were identical in both foals. Rupture occurred despite prior deworming, withholding of food and water before anesthesia, and care in induction of anesthesia and recovery. Surgeons should be aware of the potential of cecal rupture in horses anesthetized for elective surgery.
Small-intestinal volvulus as a complication of acquired inguinal hernia in two horses. Volvulus of the small intestine was diagnosed as a complication of acquired inguinal herniation in 2 horses. One of the horses continued to have signs of pain after reduction of the hernia. The volvulus was diagnosed at a second surgery, but the intestine was devitalized, and the horse was euthanatized. Ventral midline exploratory surgery was performed on the second horse, in conjunction with an inguinal approach. The small-intestinal volvulus was diagnosed and corrected at this time. It is suggested that ventral midline abdominal exploration be performed when acquired inguinal herniation caus...
[The treatment of insertion desmopathy in the metatarsus of horses]. Metacarpal or metatarsal exostoses were diagnosed in 112 horses used for sport purposes between January 1976 to December 1987. Fourteen of these patients were treated surgically by subperiosteal removal of the exostosis. All animals which could be followed up had returned to their original use. The average time of use after discharge from the clinic was 38.4 months. Surgery was successful in completely removing the exostoses in 58.3% of these horses. The indications for anaesthesia and resection of the ulnar nerve are discussed.
