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.
Alterations in horse blood cell count and biochemical values after halothane anesthesia. Quantitative changes in hematologic and serum biochemical values associated with prolonged general anesthesia produced by known alveolar doses of halothane in oxygen were determined in six young, healthy horses under laboratory conditions. In addition, 25 young equine patients anesthetized for shorter periods under clinical conditions were similarly (except hematologic values) prospectively evaluated. In normal horses, muscle- and hepatic-derived serum biochemical values were mildly increased immediately after anesthesia. Values after anesthesia remained at greater than base-line values for up...
Vascular anatomy and surgical technique for bilateral adrenalectomy in the equid. The vascular anatomy of the adrenal glands and a surgical technique for bilateral adrenalectomy in the equid are described. Bilateral adrenalectomy was performed in six ponies and one horse via bilateral transcostal retroperitoneal approaches through the 18th rib during a single anesthetic period. Complications included hemorrhage from the right side only and pneumothorax which usually occurred on the right side. One pony died as a result of the surgical technique. Maintenance of adrenal function was accomplished with desoxycorticosterone pivilate and prednisolone.
Surgical implantation of cardiovascular devices in the thorax of the horse. A surgical thoracotomy and implantation of an electromagnetic flow probe around the ascending aorta and catheters in the left ventricular (LV) apex of the horse were evaluated. Sixteen operations were done: 4 horses were used for acute experiments, 4 horses died from surgical manipulation, and 8 horses were studied chronically for 18 to 57 days. The electromagnetic flow probe allowed continuous measurement of stroke volume and heart rate. The LV apical catheters, in conjunction with thermal dilution techniques and pressure-sensitive devices, allowed measurement and calculation of mean arterial...
[Incarcerated scrotal hernia in a gelding (author’s transl)]. The clinical examination, anaesthesia and surgery in a gelding with an incarcerated scrotal hernia are described. The results of examination of the blood at regular intervals are shown in a table. Surgery was performed without enterectomy. The postoperation course was uneventful. It is concluded that the possibility of scrotal hernia should be borne in mind, even in geldings with colic. The incarcerated portion of the small intestine is usually found to be the jejuno-ileal junction. The anaesthesiological and surgical features of equine scrotal hernia are discussed.
Repair of bovine and equine mandibular fractures. Clinical findings, surgical repair and postsurgical care of a unilateral fracture of the mandible of a bull and of a bilateral mandibular fracture in a horse are described. Compression plating limited the pain suffered by the animals and resulted in a quick return to function of the mandibles.
Occlusion of internal carotid artery in the horse by means of a balloon-tipped catheter: evaluation of a method designed to prevent epistaxis caused by guttural pouch mycosis. A procedure developed to occlude the internal carotid artery of horses with guttural pouch mycosis was modified was modified and evaluated in nine clinically normal horses. The left internal carotid artery was ligated at its origin and occluded distally with an intraluminal balloon catheter. In four horses, the balloon-tipped catheters were left in place until these horses were euthanatized at 4 to 244 days after surgery. In the remaining horses, the catheters were removed after 10 to 14 days by a cutdown procedure, and these horses were euthanatized 1 to 60 days after catheter removal. In bot...
Repair of incisional hernias in the horse. Incisional abdominal hernias in three horses were repaired, using synthetic mesh with a fascial flap overlay. The repair of large ventral abdominal hernias of horses can be accomplished by using synthetic mesh that is sutured across the defect. This material can be placed subperitoneally, retroperitoneal but subfascial, retrofascial and subfascial, or retroperitoneal but subfascial with a fascial overlay. Advantages of using this material are that it can be used for repair of large hernias, it is easy to apply, it is strong and flexible, and it is less likely to be rejected, when compared with...
Surgical repair of fractured capital femoral epiphysis in three foals. Fracture of the capital femoral epiphysis occurred in three foals. One fracture was repaired by means of pinning under radiographic control and the two other fractures were repaired by means of trochanteric osteotomy.
Dorsal displacement of the left ventral and dorsal colon in two horses. This paper describes the clinical signs and surgical treatment of 2 cases of dorsal displacement of the left ventral and dorsal colon. The condition, in which the colon becomes enclosed in the space bounded by the base of the spleen, the dorsal aspect of the suspensory ligament of the spleen (phrenicosplenic ligament), the left kidney and the adjacent body wall, is characterised by moderate to severe pain, minimal signs of shock, no response to medical therapy and a tendency for a ventral midline abdominal paracentesis to enter the spleen. Both horses recovered after surgical replacement of th...
The effect of laryngoplasty on pharyngeal function in the horse. Using fluoroscopic techniques and videotape recordings, a study of normal deglutition was made in 2 ponies. Paryngeal function was studied at intervals after laryngoplasty on 1 animal and after a sham technique on the other. Two clinical cases of laryngeal paralysis, which had been treated by laryngoplasty, were also examined. In the 2 experimental ponies, liquid food passed into the lower respiratory tract post-operatively. One of the clinical cases appeared to swallow solid food normally, but some food material entered the larynx of the other horse. It is suggested that pharyngeal dysfunctio...
Surgical decompression for traumatic atlantoaxial subluxation in a weanling filly. A filly with ataxia and splinting and crepitation in the neck was found to have atlantoaxial subluxation. Radiographic diagnosis was based on the same criteria as those used in other species, ie, increased distance between the atlas and spine of the axis and increased distance between the dens and floor of the atlas. Extensive hemilaminectomy was performed to decompress the spinal cord. Stabilization was not attempted. Immediate postoperative response was encouraging, but the untimely death of the filly prevented further evaluation of the procedure.
A case of carpal intersynovial fistula in a horse. A tentative diagnosis of a fistula between the tendon sheaths of the right extensor carpi radialis and the intercarpal joint was confirmed by positive contrast radiography following injection of sodium diatrizoate into the joint. Surgical removal of a tag of synovial membrane and repair of the fistula was carried out. Post surgical treatment included mild exercise to prevent adhesions within the sheath. A month following discharge, contrast radiography revealed no communication between joint and tendon sheath. At this time mild distension of the sheath was relieved by aspiration and it did not...
Treatment of periocular tumours of horses using radioactive gold198 grains. The literature is briefly reviewed concerning the clinical features of equine cutaneous tumours. The data from 19 horses with periocular skin tumours are reported together with the results of their treatment by implantation with radioactive gold198. The principles governing the implantation of radioactive sources are explained and a method for computing the initial activity of the sources is outlined. Five histologically different tumour types were treated in this series of 19 horses, 2 horses were bilaterally affected. The techniques of implantation using a simple needle/stillette combination...
Endometrial histology and post-partum mares treated with progesterone and synthetic GnRH (AY-24,031). Foal heat was significantly delayed in 15 Thoroughbred and Quarter-horse mares by 200 mg progesterone in oil from Days 5--14 post partum. Nine of these mares subsequently received daily i.v. injections of 2 mg of a synthetic GnRH preparation (AY-24,031) from Day 2 of the progesterone-delayed oestrus but this treatment did not significantly shorten oestrus or hasten ovulation. Uterine biopsies taken on Day 15 post partum from all the mares showed a mixed endometrial morphology having both oestrous and dioestrous characteristics. There was an increased proliferation of endometrial glands in thes...
Internal fixation of fractures of the third phalanx in three horses. The technique of internal fixation of intra-articular fractures of the third phalanx using lag screw interfragmentary compression is described. Three cases are discussed and the successful treatment of infection and osteomyelitis described in one of them. Despite this potential complication internal fixation offers a better prognosis and also a more rapid return to work than non-operative treatments.
Surgical correction of deviated nasal septum and premaxilla in a colt. A 6-month-old Appaloosa colt had a deviation of the premaxilla and nasal septum as well as a dorsal hump of the nasal bone and maxillomandibular malocclusion. Two surgical procedures were performed 12 weeks apart to correct these anomalies. An intraoral approach and autogenous rib graft were used to correct the malocclusion and deviation of the premaxilla. Osteotomy of the nasal bone and removal of the nasal septum were performed to help correct the deviation and to facilitate free air passage through the nares.
Surgical approach for medial meniscectomy in the horse. After preliminary studies on cadavers, a surgical approach was developed for removal of the medial meniscus, offering maximal exposure and minimal trauma to the articular surfaces of the medial tibial plateau and femoral condyle. Medial meniscectomy was then performed on 10 clinically normal horses that had been given general anesthesia. Nine horses were euthanatized at intervals of 1 to 6 months, and the joints were evaluated grossly and histologically. (One horse will be examined 1 year after surgery). Medial meniscus tears were diagnosed in 5 horses; medial meniscectomy was done on 4 horses...
Surgical treatment of osteomyelitis in the metacarpal and metatarsal bones of the horse. The case histories of four horses with osteomyelitis involving the metacarpal and metatarsal bones are reviewed and the surgical treatments discussed. The horses recovered after curettage of all infected tissue and post operative drainage. The role of antibiotics in treatment is considered and reference is made to the acute treatment of deep wounds to avoid osteomyelitis.
Splenectomy in the horse. Splenectomy was successfully performed on 2 aged horses to facilitate experimental studies of Babesia equi infection. Resection of part of the 17th rib provided the most acceptable approach and avoided many complications encountered on removing part of the 16th rib.
Evaluation of inferior check ligament desmotomy for treatment of acquired flexor tendon contracture in the horse. The usefulness of inferior check ligament desmotomy as a treatment for acquired tendon contracture in horses was evaluated in 13 cases of deep digital flexor (DDF) contracture and in 3 cases of combined superficial digital flexor (SDF) and DDF contracture. In 8 of 9 cases of DDF contracture in which the dorsal surface of the hoof had not passed beyond being vertical to the ground, the surgical procedure was successful in returning the limb to a normal position and function. Compared with DDF tenotomy, inferior check ligament desmotomy was a superior treatment technique because of decreased pos...
Repair of physeal fractures of the tuber olecranon in the horse, using a tension band method. Physeal fractures of the tuber olecranon of 4 horses were treated, using the tension band method of compression fracture repair. A cortical bone screw and Steinmann pin were placed through the proximal fragment into the distal parent bone parallel to the palmar border of the olecranon. The tension band was placed dorsal to the Steinmann pin and anchored in a hole through the shaft of the ulna 10 cm distal to the tuber olecranon. Of the 4 foals, 2 became pasture sound, 1 is now being worked under saddle, and the 4th showed no signs of lameness 5 months after surgery.
