Survey of equine castration techniques,preferences and outcomes among Australian veterinarians          下载免费PDF全文

CD Owens  KJ Hughes  BJ Hilbert  J Heller  S Nielsen  GD Trope 《Australian veterinary journal》2018,96(1-2):39-45

Objectives

(1) To collect the perceptions of veterinarians performing equine castrations in Australia on techniques, preferences and outcomes, (2) to investigate veterinarian use and experience with the Henderson castrating instrument and (3) to investigate potential associations between demographics, castration methods and techniques, and complications.

Design

Online survey of members of the Australian Veterinary Association’s Special Interest Group, Equine Veterinarians Australia (EVA).

Methods

A link to the survey was included in the EVA e‐newsletter and practices on the EVA website were contacted by telephone and follow‐up email. Fisher’s exact test was used to determine associations between ligation and complications. A generalised linear model with a negative binomial family was used to determine associations between count response variables and categorical independent variables.

Results

Responses were obtained from 138 veterinarians (response rate, 13.1%) who performed 5330 castrations over 12 months. Castrations were most commonly performed in the field, on anaesthetised horses, using emasculators, via an open approach and without ligation of the spermatic cord. Estimated complications after use of emasculators were swelling (25%), haemorrhage (5%) and infection (5%). The Henderson instrument was used by approximately 10% of respondents and its use for castration was associated with fewer reports of postoperative swelling compared with emasculators (P = 0.002). Rates of evisceration with the Henderson and emasculator methods were comparable (0.43% and 0.9%, respectively).

Conclusion

Castration preferences varied widely among survey participants. Reported complication types and rates were comparable to those reported previously in other countries. Perceptions that the Henderson instrument was associated with less swelling should be investigated further via a prospective controlled investigation.  相似文献

Orthopedic Infections in Equine Long Bone Fractures and Arthrodeses Treated by Internal Fixation: 192 Cases (1990–2006)     

Benjamin J. Ahern  Dean W. Richardson  Raymond C. Boston  Thomas P. Schaer 《Veterinary surgery : VS》2010,39(5):588-593

Objective: To determine the rate of postoperative infection (POI) for internal fixation repaired equine long bone fractures and arthrodeses and identify associated risk factors. Study Design: Case series. Animals: Horses (n=192) with fracture repair of the third metacarpal and metatarsal bones, radius, ulna, humerus, tibia, and femur, or arthrodesis with internal fixation. Methods: Medical records (1990–2006) were reviewed for signalment, anatomic location, fracture classification and method of repair, technique and surgical duration, bacterial species isolated, postoperative care, onset of POI, and outcome. Results: Of 192 horses (171 [89%] closed, 21 [11%] open fractures), 157 (82%) were discharged from the hospital. Infection occurred in 53 (28% horses), of which 31 (59%) were discharged. Repairs without POI were 7.25 times more likely to be discharged from the hospital. Closed fractures were 4.23 times more likely to remain uninfected and 4.59 times more likely to be discharged from the hospital compared with open fractures. Closed reduction and internal fixation was associated with a 2.5‐fold reduction in rate of POI and a 5.9 times greater chance for discharge from the hospital compared with open reduction and internal fixation. Females had a strong trend for increased POI when compared with colts and stallion but not geldings. Conclusions: Overall rate of POI was 28%. Fracture classification, method of repair, gender, and surgical duration were significant risk factors.  相似文献   

Early harvest and ensilage of forage sorghum infected with ergot (Claviceps africana) reduces the risk of livestock poisoning     

BJ Blaney  MJ Ryley  BD Boucher 《Australian veterinary journal》2010,88(8):311-312

Sorghum ergot produces dihydroergosine (DHES) and related alkaloids, which cause hyperthermia in cattle. Proportions of infected panicles (grain heads), leaves and stems were determined in two forage sorghum crops extensively infected 2 to 4 weeks prior to sampling and the panicles were assayed for DHES. Composite samples from each crop, plus a third grain variety crop, were coarsely chopped and half of each sealed in plastic buckets for 6 weeks to simulate ensilation. The worst-infected panicles contained up to 55 mg DHES/kg, but dilution reduced average concentrations of DHES in crops to approximately 1 mg/kg, a relatively safe level for cattle. Ensilation significantly (P = 0.043) reduced mean DHES concentrations from 0.85 to 0.46 mg/kg.  相似文献   

Acute onset of pulmonary necrotising arteritis in a dog with a left-to-right patent ductus arteriosus     

BJ GAVAGHAN  J-M LAPOINTE  WP THOMAS 《Australian veterinary journal》1998,76(12):786-791

A 12-week-old, clinically normal Chihuahua was referred for investigation for a continuous heart murmur. Cardiac evaluation revealed an anatomically and haemodynamically typical left-to-right shunting patent ductus arteriosus. The continuous wave Doppler measurement of peak ductal jet velocity of 5.6 m/s was suggestive of a normal pulmonary to systemic arterial pressure ratio. The dog returned 16 days later with right heart failure and severe pulmonary hypertension. Marked reduction in left-to-right shunting was demonstrated and the ductal jet velocity had decreased to 2.5 m/s. Immediate ductus ligation, oxygen therapy before and after the operation, and administration of hydralazine failed to reduce pulmonary hypertension, and the dog was euthanased. Histopathological examination of the lung showed pulmonary necrotising arteritis with acute and chronic arterial lesions. Chronic pulmonary vascular changes related to high flow have been associated with altered nitric oxide and endothelin responses. These changes may be responsible for the acute onset of pulmonary hypertension due to relatively minor vascular insults in some human and veterinary patients with left-to-right shunts. The potential for acute progression supports the recommendations for early ductus ligation and the prognostic importance of detecting pulmonary hypertension presurgically in patent ductus arteriosus patients.  相似文献

Mechanical Evaluation of the Equine Laryngoplasty     

Benjamin J. Ahern  Eric J. Parente 《Veterinary surgery : VS》2010,39(6):661-666

Objectives: Mechanical evaluation of the equine laryngoplasty. Study Design: Experimental. Animal Population: Cadaveric cricoid (n=36) and arytenoid (46) cartilages. Methods: Arytenoid and cricoid cartilage specimens were embedded for testing. Suture material (2 Ethilon^®, 5 Ethibond^®, or 5 Fiberwire^®) was inserted simulating laryngoplasty procedures. Constructs were evaluated in single or cyclic loading. Single cycle tests recorded load at failure and stiffness. Cyclical tests recorded displacement after 10,000 cycles. ANOVA and t‐tests were used (significance P<.05). Results: The arytenoid Ethibond^® (241.10±47.67 N) constructs were stronger in single cycle than Ethilon^® (133.85±27.89 N) and Fiberwire^® (142.67±32.40 N). The cricoid Ethibond^® (220.39±49.11 N) constructs were stronger than Ethilon^® (171.93±21.19). The stiffness of Ethilon^® constructs was lower in both the arytenoid and cricoid compared with Ethibond^® and Fiberwire^®. The arytenoids failed at a lower load than the cricoids for Ethilon^® and Fiberwire^® but not Ethibond^® constructs. In cyclic testing complete failure of either cartilage did not occur. Arytenoid Ethibond^® constructs (0.43±0.21 mm) had less distraction than Ethilon^® (0.92±0.41 mm) and a trend for less compared with Fiberwire^® (0.83±0.43 mm; P=.0513). Cricoid Ethibond^® constructs (0.45±0.18 mm) had less distraction compared with Ethilon^® (1.04±0.30 mm) and Fiberwire^® (0.97±0.45 mm). Conclusions: Ethibond^® was superior to Ethilon^® and Fiberwire^® constructs in vitro. Clinical Relevance: Abduction loss after laryngoplasty is a common complication. The results of this study suggest that the use of Ethibond^® should minimize abduction loss after surgery relative to the other materials tested.  相似文献
