Seventy physeal fractures in horses were initially managed by euthanasia (18), stall confinement (25), application of a cast (7), or internal fixation (20). Of the 52 physeal fractures initially managed with stall confinement, a cast, or internal fixation, 23 (44%) healed and 13 (25%) of these horses became sound. The number of horses less than 4.5 months of age with pressure physeal fractures that became sound was significantly higher (p < 0.05) than the number of horses greater than 4.5 months of age. The number of horses with functional, pain-free limbs (sound horses) or functional limbs (lame horses) was not significantly different (p > 0.05) for Salter-Harris Type I, II, III, or IV pressure physeal fractures; however, critical examination for growth disturbances was not performed. The number of horses with pressure or traction physeal fractures of less than 5 days duration prior to presentation that healed or became sound was not significantly different (p > 0.05) when compared with those horses with fractures of greater than or equal to 5 days duration. 相似文献

Epidural Morphine in Goats after Hindlimb Orthopedic Surgery 总被引:1,自引:0,他引:1
Morphine (0.1 mg/kg) diluted with 0.9% saline to a volume of 0.13 mL/kg was administered into the epidural space at the lumbosacral junction in 10 halothane-anesthetized goats immediately before discontinuation of halothane. The same volume of 0.9% saline was given to control group of eight anesthetized goats. Both groups had undergone an orthopedic procedure that replaced the anterior cruciate ligament with a patellar tendon autograft. The appearance and unprovoked behavior of goats in the morphine group were significantly different (p < .05) from the saline groups. The goats in the morphine group were more sedate and struggled less during recovery. Epidural morphine did not produce respiratory depression or bloat during a 9 hour observation period. Heart rate, respiratory rate, and blood pressure (mean, systolic, and diastolic) of the morphine group did not differ from those of the control group. 相似文献

Dogs given parenteral anticholinergic drugs have been thought to be at risk for development or exacerbation of elevated intraocular pressure (IOP). In a randomized, blinded, placebo-controlled study, we evaluated the effect of intramuscular glycopyrrolate (0.01 mg/kg) on pupil diameter and IOP in unanesthetized normal dogs. Treatment with glycopyrrolate did not change pupil diameter or IOP from baseline, nor were there differences between glycopyrrolate and saline-treated (control) dogs. In addition, the authors retrospectively reviewed the medical records of 2,828 dogs undergoing general anesthesia between April 1987 and September 1990 to determine if there was an association between parenteral anticholinergic medication and postanesthetic elevation in IOP. The authors also determined the frequency of bradycardia requiring anticholinergic therapy during anesthesia in dogs with glaucoma. Of the 2,828 cases reviewed, the records of 46 dogs coded for glaucoma were examined in detail. The 46 dogs underwent 62 episodes of anesthesia, with 23 episodes including exposure to an anticholinergic drug. An increase in IOP from preanesthetic to postanesthetic measurement occurred in three dogs. One of these dogs received anticholinergic medication for bradycardia during anesthesia. The postanesthetic elevation in IOP in this dog was probably not drug related. Preanesthetic anticholinergic administration did not affect the incidence of anticholinergic administration for bradycardia during the anesthetic episode. Anticholinergic therapy during anesthesia was more frequent when the preanesthetic medication included an opiate drug. These studies do not indicate an association between parenteral anticholinergic administration and elevations in IOP. 相似文献

Electrosurgical arthrotomy and excision of infra-articular soft tissue masses from the metacarpophalangeal joint was performed in 12 horses. In six of the 12 horses, osteochondral fragments from the dorsoproximal aspects of the first phalanx were also removed. The electrosurgical scalpel afforded excellent intraoperative efficacy for arthrotomy and relatively bloodless excision of soft tissue masses without the need for a tourniquet. There were no complications associated with healing in 11 of the 12 horses. A retraction technique that used careful positioning of a Langenbeck periosteal elevator relative to the collateral ligaments provided access to both medial and lateral margins of intra-articular masses. With this technique, all masses could be removed through one central arthrotomy incision. 相似文献

Intravenous diazepam and ketamine were used to induce anesthesia in four dogs with complete heart block while cardiac and hemodynamic measurements were made. Immediately after induction there were minor changes in the measured variables. However, 5 minutes after injection, with the dogs supine and mechanically ventilated, cardiac output was reduced 41%. An additional 20 dogs with heart block had uncomplicated induction when this drug combination was used. The combination of diazepam and ketamine appears useful for inducing anesthesia in dogs with heart lesions, although further studies must be done to establish its value in such patients. 相似文献

Fatal complications have been reported during anesthesia in dogs that received a standard (1–2 g/kg IV) dose of mannitol during intraocular surgery. A lower dose (0.25 g/kg IV), which had been shown to reduce intracranial pressure in humans, was evaluated during halothane anesthesia in dogs. There were no significant changes in intraocular pressure (IOP) or cardiovascular variables. This lower dose (0.25 g/kg IV) did not reduce IOP and would not be of benefit in dogs undergoing intraocular surgery. 相似文献

Total gastric emptying time was determined in nine mongrel dogs using a barium meal contrast procedure. Within the group, total gastric emptying time ranged from 7.0–15.0 hours. Comparison of the population mean showed a statistical difference (p − 0.01) from previously published values. Individual dogs showed consistent total gastric emptying time over three trials. The technique can be used to test the effect of a procedure on total gastric emptying time when a normal value has been established for the dog. Due to the wide range of normal values observed, evaluation of clinical patients could be difficult unless there is a gross abnormality in function. 相似文献

A modified bone-flap technique was used to expose space occupying lesions that involved the conchofrontal sinus, ethmoturbinates, and caudal nasal cavity in five horses. The most common clinical findings were chronic nasal discharge and upper airway obstruction. Surgical intervention was based on endoscopic and radiographic interpretation. The triangulated bone-flap technique increased surgical exposure to the conchofrontal sinus by almost twice the area observed in previously described surgical techniques. The major advantages were that this technique allowed excellent visualization, thorough palpation, and surgical manipulation within the sinus and associated structures. Complications were minimal. One horse was euthanized 1 month postoperatively with recurrence and spread of a mycotic granuloma. The technique extended the usefulness of the other four horses in a 9 to 24 month follow-up period, although the obstructing lesion recurred after 2 years in one of the four horses. 相似文献

Eight synthetic casting materials were evaluated with respect to tensile and fatigue strengths, exothermicity (evolution of heat during polymerization), permeability (porosity), radiolucency, and cost. Strength determination for a five-layer sample included measurement of the ultimate load at which a material failed, the ability to absorb energy, and the stiffness a material possessed after application of a cyclic stress. Results indicated that Vet Cast was superior with respect to tensile and fatigue strengths. The exothermic reaction associated with the "curing" or polymerization process was evaluated and not considered excessive although Ultra Cast attained a temperature of 48.0°C and was uncomfortable to handle during application. Permeability was determined. Delta Lite and Hexcelite NS were the most permeable materials and dried more rapidly and thoroughly after immersion than the other casting materials. Hexcelite NS was considered the least radiolucent material and was the most expensive material studied. Each of the synthetic casting materials demonstrated superiority in one or more of the categories tested. No one product demonstrated consistent superiority in criteria appropriate for clinical application. 相似文献
