Adverse Drug Reactions: Report of the Australian Veterinary Association Adverse Drug Reaction Subcommittee, 1993     

JE MADDISON 《Australian veterinary journal》1994,71(2):53-57

SUMMARY Fifty-nine reports of suspected adverse drug reactions (ADRs) were received by the Adverse Drug Reaction Subcommittee of the Australian Veterinary Association from April 1992–March 1993 inclusive. The number of reports received/number of animals involved per species was: dogs (30/43); cats (11/14); horses (8/10); cattle (9/30); ferret (1/1). Of these, 37 (63%) were classified as definite ADRs and 12 (20%) as probable ADRs. In 10 (17%) reports an ADR could not be substantiated or there was insufficient information available to make a decision. Twenty-three reports involved apparent hypersensitivity reactions and 5 reports were associated with ‘off-label’ use. Of the definite and probable reports of suspect ADRs the most frequent types of drugs involved were antimicrobials (9 reports), anthelmintics (9 reports), vaccines (7 reports), insecticides (6 reports), vitamin preparations (6 reports), topical anti-inflammatory/antimicrobial/antifungal skin preparations (3 reports) and nonsteroidal anti-inflammatory preparations (3 reports). Single reports concerning definite or probable ADRs to an anticholinergic, an anaesthetic agent, a corticosteroid, an anabolic steroid and a chondroprotective drug were received.  相似文献   

Blindness in goats following ingestion of Stypandra glauca     

RJ WHITTINGTON †  JE SEARSON  SJ WHITTAKER‡  JRW GLASTONBURY 《Australian veterinary journal》1988,65(6):176-181

Twenty-seven of 427 Angora goats of mixed age became blind within a week of consuming large amounts of Stypandra glauca ("nodding blue lily"). A further 200 goats were depressed for several weeks, but most subsequently recovered. Blindness was associated with optic nerve neuropathy which is postulated to have followed compression of the optic nerves within the bony optic canals as a result of severe myelin oedema. Histologically, the intracanalicular portion of the optic nerve was sclerotic, while the intracranial portion of the optic nerve and the optic tracts were degenerating. The retrobulbar portion of the optic nerve was relatively unaffected. In addition, multifocal retinal photoreceptor degeneration was found ophthalmoscopically and histologically. The syndrome was not reproduced during a trial in which 2 goats were fed 4 and 20 kg of S. glauca harvested after it had finished flowering, more than 3 weeks after the first natural cases of blindness. Based on epidemiological and pathological data we propose that S. glauca is toxic to stock, but only for a short period while flowering in spring.  相似文献

Factors affecting the relationship between arterial and end-tidal carbon dioxide pressures in the anaesthetised horse     

JE Rainger  CM Dart  NR Perkins 《Australian veterinary journal》2010,88(1-2):13-19

Objective To assess the effects of the duration of anaesthesia, position of recumbency, mode of ventilation, anaesthetic drug protocol, patient age and type of surgical procedure on the usefulness of capnometry as a measure of the partial pressure of arterial carbon dioxide (P_aco ₂) during general anaesthesia in horses. Design A prospective study compared the P_aco ₂ values with those of partial pressure of end-tidal carbon dioxide (ETco ₂) in horses anaesthetised for elective or emergency surgical procedures. The difference between P_aco ₂ and ETco ₂ (P_aco ₂− ETco ₂) and the physiological dead space to tidal volume ratio (V_D/V_T) were calculated. The effects of the study parameters on these variables was determined. Results The agreement between P_aco ₂ and ETco ₂ was poor. P_aco ₂− ETco ₂ and V_D/V_T during the first 60 min of anaesthesia was significantly less than after 60 min of anaesthesia. Mode of ventilation, position of recumbency, anaesthetic drug protocol, patient age and type of procedure did not have a significant affect on either value. Conclusions P_aco ₂− ETco ₂ in anaesthetised horses can be large, making ETco ₂ unreliable as a predictor of P_aco ₂ and for assessment of pulmonary ventilation. For anaesthesia lasting less than 60 min at least one blood gas analysis of an arterial blood sample is required to assess P_aco ₂− ETco ₂. Arterial blood gas analysis should be repeated after 60 min of general anaesthesia.  相似文献

Objective To estimate the prevalence of carriage of methicillin‐resistant Staphylococcus aureus (MRSA) among Australian veterinarians. Methods Individuals attending veterinary conferences in Australia in 2009 were recruited to provide nasal swabs and complete a questionnaire about their professional activities. Swabs were processed by standard methods for detecting MRSA and questionnaire responses were used to group veterinarians according to their areas of major work emphasis (species and practice type). Prevalence was estimated for each of these grouping and contingency tables and regression tree analysis used to explain the variation in MRSA carriage. Results Among the 771 respondents ‘industry and government veterinarians’ (controls) had the lowest prevalence of MRSA carriage at 0.9%. Veterinarians with horses as a major area of work emphasis had a prevalence of 11.8% (13‐fold that of controls) and those whose only major emphasis was horses had a prevalence of 21.4% (23‐fold that of controls). Veterinarians with dogs and cats as a major activity had a 4.9% prevalence (5‐fold that of controls). Prevalence rates for other major activities (pigs, dairy and beef cattle, avian and wildlife) were also increased, but were estimated from smaller numbers of respondents. Regression tree analysis clearly isolated equine veterinarians and dog and cat practitioners as groups at increased risk of carriage of MRSA. Conclusion Carriage of MRSA is a notable occupational health issue for veterinarians in clinical practice in Australia, particularly those who work with horses.  相似文献   

Cooled Storage of Canine Semen: in vitro Effects of Different Concentrations of an Antibiotic Combination on Growth of Mollicutes     

AC Becher  J Spergser  C Aurich  E Zottler  JE Aurich  S Schäfer‐Somi 《Reproduction in domestic animals》2013,48(6):961-966

The aim of this study was to examine effects of an antibiotic combination at different concentrations on growth of mycoplasma and ureaplasma during cooled storage of canine semen (n = 20). Semen aliquots were diluted with Tris–citric acid–fructose–egg yolk extender containing either 1.0 g/l streptomycin and 0.6 g/l benzylpenicillin (control) or a combination of gentamycin, tylosin, lincomycin and spectinomycin (GTLS‐1: 0.25, 0.05, 0.15 and 0.3; GTLS‐2: 0.5, 0.1, 0.3 and 0.6; GTLS‐3: 1.0, 0.2, 0.6 and 1.2 g/l). Samples were assessed for motility and membrane integrity by computer‐assisted sperm analysis immediately after dilution and at 24, 48 and 72 h of cooled storage. Morphologically, normal spermatozoa were determined, and bacterial culture was performed at 24 and 72 h. Mycoplasma spp. were detected in 14 of 20 ejaculates (70%) with severe growth in 12 samples. A reduction but not total elimination of mycoplasma growth occurred in all GTLS extenders with the most pronounced reduction in group GTLS‐3 (control vs GTLS‐1 and GTLS‐2 p < 0.05, control vs GTLS‐3 p < 0.001). Ureaplasmas were detected in four ejaculates, and growth was reduced to the same extent in GTLS and control extender. Progressive motility in all groups, total motility in groups GTLS 1–3 and percentage of membrane‐intact spermatozoa in groups GTLS 2 and 3 decreased slightly (p < 0.05) over time. In conclusion, dilution of canine semen with GTLS extender has no major detrimental effects on spermatozoa during cooled storage. It reduced the growth but did not totally eliminate mycoplasmas and ureaplasmas from cooled‐stored dog semen.  相似文献   

Cardiovascular effects of propofol alone and in combination with ketamine for total intravenous anesthesia in healthy cats     

JE  Ilkiw  PJ Pascoe 《Veterinary anaesthesia and analgesia》2003,30(2):102-103

This study was designed to compare the cardiovascular effects of equipotent maintenance of anesthetic doses (determined in a previous study) of propofol and propofol/ketamine, administered with and without noxious stimulation. Six healthy adult cats were anesthetized with propofol (loading dose 6.6 mg kg^?1, infusion 0.22 mg kg^?1 minute^?1), and instrumented to allow determination of blood gas and acid–base balance and measurement of blood pressures and cardiac output. The propofol infusion was continued for a further 60 minutes after which measurements were taken prior to and during application of a noxious stimulus. The propofol infusion was decreased to 0.14 mg kg^?1 minute^?1, and ketamine (loading dose 2 mg kg^?1, infusion 23 µg kg minute^?1) was administered. After a further 60 minutes, measurements were again taken prior to and during application of a noxious stimulus. The data were analyzed, using several Repeated Measures anova (first, ketamine/propofol and noxious stimulation were each treated as within‐subject factors; secondly, the levels of these two factors were combined into a single within‐subject factor). Mean arterial pressure, CVP, PAOP, SI, CI, SVRI, PVRI, oxygen delivery index, oxygen consumption index, oxygen utilization ratio, PvO₂, pHa, PaCO₂, bicarbonate concentration, and BD values collected during propofol administration were not changed by addition of ketamine and reduction of propofol concentration or by application of a noxious stimulus under propofol alone. Application of a noxious stimulus under propofol alone did, however, significantly increase HR and PaO₂, and these responses were not blunted by the addition of ketamine. Compared with propofol, administration of ketamine and reduction of propofol concentration significantly increased PAP and venous admixture, and significantly decreased PaO₂. Although application of a noxious stimulus to cats under propofol alone did not significantly change CVP, SI, CI, PVRI, oxygen delivery index, and oxygen consumption index, significant differences were found in these variables between propofol and propofol/ketamine. In conclusion, propofol alone provided cardiopulmonary stability; addition of ketamine did not improve hemodynamics but did decrease oxygenation.  相似文献
