A survey of dog and cat anaesthesia in a sample of veterinary practices in New Zealand

AIMS: To survey current anaesthesia practices for dogs and cats in small and mixed animal practices in New Zealand in order to improve anaesthesia education.

METHODS: A questionnaire was sent to 440 small and mixed animal practices, including questions regarding the type of practice, preanaesthetic examination, anaesthetic drugs and management, anaesthetic machines, monitoring and topics of interest for continuing professional development.

RESULTS: Responses were obtained from 113/440 (26%) practices, with 78 (69%) respondents from small and 35 (31%) from mixed animal practices. A preanaesthetic physical examination was carried out by >95% of respondents and premedication was usually given to dogs (112/113; 99%) and cats (95/113; 85%). Acepromazine was the preferred sedative for dogs and cats, with morphine or buprenorphine. Propofol and alfaxalone were the preferred induction agents, and isoflurane was preferred for maintenance in both dogs and cats. A venous catheter was usually placed for anaesthesia in dogs (59/113; 52%), but less so in cats (39/113; 35%). Perioperative fluid was administered at 10?mL/kg/hour by 62/110 (56%) respondents. Intubation was usually used for anaesthesia in dogs (111/112; 99%), and cats (87/112; 78%). Almost 40% of respondents usually administered supplementary oxygen if patients were not intubated. Local analgesia was used by 69/111 (88%) respondents sometimes or always if applicable. Morphine or buprenorphine, and meloxicam were common choices for post-operative analgesia after neuter surgery in dogs and cats. A semiclosed (non-rebreathing) system was used in animals weighing <10?kg, and a Mapleson E or F non-rebreathing circuit was used by 66/109 (61%) practices. Only 15/111 (14%) practices had a ventilator in their practice. A dedicated anaesthetist was usually used by 104/113 (92%) practices, and apnoea alarms, pulse oximeters, thermometers and oesophageal stethoscopes were the main monitoring devices available in practices. Loco-regional block, pain management, and anaesthetic drugs were the main topics of interest for continuing education.

CONCLUSIONS AND CLINICAL RELEVANCE: Responses by the veterinarians taking part in this survey indicated that they had a reasonably good standard of anaesthetic practice. A physical examination was carried out preanaesthesia, and premedication including analgesia was routinely administered to most patients. A dedicated anaesthetist usually monitored patients and most respondents reported they had access to basic anaesthetic monitoring equipment. Areas where changes could lead to improved anaesthetic practice were increased use of I/V catheterisation, endotracheal intubation, and supplementary oxygen, and reduced I/V fluid rates.     

Routine veterinary anaesthetic management practices in South Africa

A survey of the routine anaesthetic management of dogs and cats during sterilisation by veterinarians in South Africa was conducted. This report describes the premedication, induction and maintenance agents most commonly used in dogs and cats. Information about monitoring of patients during the procedure and who is responsible for induction of anaesthesia and monitoring was obtained. Questionnaires were analysed with regard to demographic data, practice size, continuing education, the number of surgical procedures and sterilisations performed per week and an estimate of yearly mortality. Acetylpromazine is the most commonly used premedication in dogs and xylazine in cats. Thiopentone in dogs and alphaxalone/alphadolone in cats were the induction agents most commonly used. Alphaxalone/alphadolone in cats and halothane in dogs are the most commonly used maintenance agents. Records of anaesthesia are poorly kept and monitoring of patients is poorly performed. Respiratory rate is the parameter most commonly monitored (90.7%), and in most cases is the sole parameter. On average 10.34 +/- 8.25 cats were operated per week, of which 5.45 +/- 5.60 were sterilised; 17.79 +/- 11.61 dogs were operated per week, of which 8.65 +/- 7.10 were sterilised. In total, 190 patients died under anaesthesia, a mortality rate of 1:1,243. Just over 50% of practitioners had attended continuing education courses during their careers.     

Policies for the vaccination of cats and dogs in New Zealand veterinary practices

AIMS: To determine current practices and attitudes towards vaccination of dogs and cats of veterinarians in New Zealand; the methods used for informing clients on which vaccines to use, and the preferred site for vaccination of cats.

METHODS: A postal questionnaire was sent to all 483 listed veterinary practices in New Zealand during February 2012. Some questions were specific to pet dogs, cats, or working farm dogs. Responses were categorised according to practice type and geographical region of the respondent. Factors associated with respondent recommendation of annual vaccination with modified live viral (MLV) vaccines were examined using logistic regression analysis. Vaccines that were considered to be essential for every animal were defined as core; those that may be recommended for animals whose location or lifestyle placed them at risk, were defined as non-core.

RESULTS: There were 204 useable returns, equivalent to a response rate of 42.2%, distributed across the country. Annual vaccination with MLV vaccines of dogs was recommended by 54/198 (27.3%) respondents, and of cats by 107/181 (59.1%) respondents. Factors associated with the recommendation of annual administration of MLV vaccines to dogs included being a companion animal practice, a desire for policies on vaccination to be left to individual clinics, and having one veterinarian in the practice. Administration of the final vaccination for puppies was recommended at ≥14 weeks old by 55/185 (29.7%) respondents, and for kittens at ≥13 weeks old by 42/183 (23%) respondents. Of respondents that administered MLV vaccines annually, 62/103 (60.2%) believed reducing the frequency of vaccination would reduce income, and 52/103 (50.5%) considered it would have a negative effect on animal health. Advice to enable clients to decide which non-core vaccines were administered was given by 181/199 (91%) respondents. Factors considered when recommending a vaccine included consideration of risk to individual patients (190/203; 93.6%), requirements of boarding kennels/catteries (165/203; 81.3%) and clinic vaccination policy (142/203; 70%). The preferred site for administering MLV vaccines to cats was the dorsal neck or inter-scapular region (137/198; 69.2%). Amongst respondents, 18 wanted disease surveillance information to allow for truly informed decisions to be made about vaccination.

CONCLUSIONS AND CLINICAL RELEVANCE: Veterinarians can now compare their own vaccination practices and attitudes with those of veterinarians nationally, and internationally. There is a need for national surveillance information and for continued education of the public and commercial kennel and cattery owners for optimal vaccination strategies to be developed.     

A review of veterinary practice in New Zealand

Extract

The development of veterinary practice in New Zealand over the past thirty years has been phenomenal. I have been engaged in practice and to some extent involved with this development during this time. Perhaps by stopping to look at where we are, where we have come from, and how, we may help to guide future development.     

The veterinary profession in New Zealand

Extract

At the beginning of this new decade, the veterinary profession in New Zealand faces a future of boundless opportunity. After a rapid and difficult growth period of twenty years, the profession is now well established as an entity, and if we, its members, show wisdom and vision, we can ensure that veterinary science will take its rightful place in the progress of New Zealand. If we fail, the profession will find itself playing a minor role in the future. We dare not allow ourselves to just drift into the years ahead.     

A survey of needle handling practices and needlestick injuries in veterinary technicians

A survey of veterinary technicians identified that needlestick injuries are very common, with 210/226 (93%) technicians reporting at least one needlestick injury over the course of their career. One hundred sixty-seven (74%) had experienced a needlestick injury during the preceding year. Exposure to animal blood and various drugs was common. It was particularly concerning that needlestick injuries involving chemotherapeutic agents and prostaglandin were reported. Eight (3.5%) technicians had required medical care for a needlestick injury and 2 (0.8%) had lost time at work. The approach to sharps handling and needlestick injury avoidance was poor and most needlestick injuries had not been reported to employers. Measures need to be undertaken to improve sharps handling practices to reduce the number of needlestick injuries among veterinary technicians.     

Demographic survey of private veterinary practices in western Canada

A workforce survey of private veterinary practices in western Canada was conducted in 2020. Data were obtained on 526 practices (response rate = 39.5%) and 1445 individual veterinary practitioners. Overall, 68.4% of practitioners identified as female, with 4 times as many females as males comprising the youngest age cohorts (26 to 35 y) of the profession. The majority of practices (67.9%) were companion animal, followed by mixed animal (21.9%) and food animal (10.2%). Most females (77.2%) and males (57.8%) were engaged in companion animal practice, whereas 23.5% of males and 6.0% of females were food animal practitioners. During an average work week, practitioners devoted 77.4% of practice time to small animals, 15.1% to food animals, and 7.5% to equine animals. A greater proportion of males (75.2%) versus females (63.2%) worked on a full-time equivalent basis (P < 0.001). Whereas males were 1.7 times (95% CI = 1.3 to 2.3; P < 0.001) more likely to be practice owners than females, 54.5% of females were owners. Practice ownership was lower than in previous surveys, a trend that may have long-term implications with respect to the corporatization of the veterinary profession.     

A survey of beef cattle farmers in New Zealand, examining management practices of primiparous breeding heifers

AIM: To obtain an estimate of the incidence of assistance at calving in primiparous (first-calving) beef heifers and the prevalence of breeding heifers at 15 months of age in New Zealand in 2006, and to identify factors contributing to farmers' decisions regarding breeding strategies for heifers, using a survey of beef cattle farmers. METHODS: A questionnaire was sent to farmers listed in a Massey University database and to members of selected breed societies, as well as published in an industry newspaper; 331 valid responses were received. Information was gathered on the age and number of primiparous heifers, number of heifers assisted, and the importance of various reasons for and against breeding heifers at 15 months of age. Respondents were also required to outline the criteria used for selecting bulls to join with heifers, and the strategies used to manage dystocia in primiparous heifers. RESULTS: Sixty-five (95% CI=58-71)% of respondents had only 2-year-old primiparous heifers in 2006, whilst a further 11 (95% CI=8-16)% had both 2- and 3-year-old primiparous heifers. The mean reported incidence of assisted calving was 7.0 (95% CI=6.4-7.5)% for 2-year-old primiparous heifers and 1.7 (95% CI=1.2-2.2)% for 3-year-old primiparous heifers. The reported incidence of assistance at calving within individual herds ranged from 0 to 100% for 2-year-old heifers. Respondents with bull-breeding herds most commonly observed their primiparous 2-year-old heifers twice daily, whilst respondents with commercial herds most commonly observed them once daily during calving. The most important reason for breeding heifers at 15 months of age was increased profit, whereas the most important reason for not breeding them at that age was concern about rebreeding performance of 2-year-old heifers. Estimated breeding value (EBV) for birthweight was the factor considered most frequently when selecting bulls to join with maiden heifers; age of bull and body shape of bull were the next most frequently considered factors. Selection of an appropriate bull was the most common strategy used to manage dystocia in 2-year-old beef heifers. CONCLUSIONS: The majority of respondents calved their heifers at 2 years of age, and increased profit was the primary motivator. Concern about the rebreeding performance of 2-year-old heifers was the most important reason among the remainder of respondents for not breeding heifers at 15 months of age. Dystocia in 2-year-old heifers was not a problem or a minor problem in most herds, but there was much variation amongst herds.

Respondents with bull-breeding herds most commonly observed their primiparous 2-year-old heifers twice daily, whilst respondents with commercial herds most commonly observed them once daily during calving. The most important reason for breeding heifers at 15 months of age was “increased profit”, whereas the most important reason for not breeding them at that age was “concern about rebreeding performance of 2-year-old heifers”. Estimated breeding value (EBV) for birth weight was the factor considered most frequently when selecting bulls to join with maiden heifers; age of bull and body shape of bull were the next most frequently considered factors.

A survey of the prevalence of Giardia in dogs presented to Canadian veterinary practices

Fecal samples (1216) were collected from dogs presented to 15 veterinary practices across Canada and tested for Giardia by ELISA for group-specific antigen. If positive, the presence of Giardia was confirmed by microscopy. Eighty-eight submissions tested positive by ELISA and microscopy. The overall prevalence rate of Giardia was 7.2%.     

Cross-sectional survey of pet ownership,veterinary service utilisation,and pet-related expenditures in New Zealand

ABSTRACT

Aims: To describe the demographics of and predictors for pet ownership, reasons for visiting a veterinarian, and pet-related expenditure in pet owners in New Zealand.

Methods: A cross-sectional online survey was conducted from 18–22 June 2015 using a permission-based panel of New Zealand residents aged ≥18 years. Questions included demographics of respondents, number of pets and reasons for owning or not owning pets, number of visits and reasons for visiting a veterinarian, and pet-related expenditure.

Results: Of the 1,572 respondents who completed the survey, 1,013 (64.4%) owned ≥1 pet. Of these, 443 owned dogs, 696 cats, 32 horses, 103 birds, 55 rabbits, and 159 owned fish. Companionship was the most common reason for getting dogs, cats, and birds; horses were mostly owned as a hobby, rabbits to provide fun for children, and fish as a source of relaxation. The majority of dog, cat, and rabbit owners considered their pets to be family members; horse owners almost equally considered their horses a hobby or a family member. The odds of pet ownership increased for respondents from a rural region, having a higher household income, having children and being female. Overall, 711/1,013 (70.2%) pet-owning respondents had taken ≥1 animal to the veterinarian in the previous year, with the most common reasons being for vaccination or annual check-ups or health issues. Respondents who considered their pets trusted companions, had a higher income, and owned dogs or cats compared with other species, were most likely to have taken their pet to a veterinarian. The greatest pet-related expenditure for all species was food. The median yearly veterinary expenditure was $200–499 by dog owners, $100–199 by cat owners, and <$100 by horse, bird, rabbit, and fish owners. The best source of information for pet-related issues was considered to be veterinarians by 724/1,001 (72.3%) owners, and the internet by 509/1,001 (50.8%) owners.

Conclusions: Among survey respondents, pet ownership was common and pets filled a variety of roles in the household. Pet owners reported spending considerable amounts of money on their pets each year, but some of them may be underutilising veterinary services despite veterinarians being considered as valuable sources of information about pet-related issues.     

A survey of respiratory viruses in New Zealand horses

AIMS: To determine which viruses circulate among selected populations of New Zealand horses and whether or not viral infections were associated with development of respiratory disease.

METHODS: Nasal swabs were collected from 33 healthy horses and 52 horses with respiratory disease and tested by virus isolation and/or PCR for the presence of equine herpesviruses (EHV) and equine rhinitis viruses.

RESULTS: Herpesviruses were the only viruses detected in nasal swab samples. When both the results of nasal swab PCR and virus isolation were considered together, a total of 41/52 (79%) horses with respiratory disease and 2/32 (6%) healthy horses were positive for at least one virus. As such, rates of virus detection were significantly higher (p<0.001) in samples from horses with respiratory disease than from healthy horses. More than half of the virus-positive horses were infected with multiple viruses. Infection with EHV-5 was most common (28 horses), followed by EHV-2 (27 horses), EHV-4 (21 horses) and EHV-1 (3 horses).

CONCLUSIONS: Herpesviruses were more commonly detected in nasal swabs from horses with respiratory disease than from healthy horses suggesting their aetiological involvement in the development of clinical signs among sampled horses. Further investigation to elucidate the exact relationships between these viruses and respiratory disease in horses is warranted.

CLINICAL RELEVANCE: Equine respiratory disease has been recognised as an important cause of wastage for the equine industry worldwide. It is likely multifactorial, involving complex interactions between different microorganisms, the environment and the host. Ability to control, or minimise, the adverse effects of equine respiratory disease is critically dependent on our understanding of microbial agents involved in these interactions. The results of the present study update our knowledge on the equine respiratory viruses currently circulating among selected populations of horses in New Zealand.     

The future of the veterinary profession in New Zealand

It is not unusual for the President of this Association or like bodies, when delivering the presidential address, to base the views and opinions expressed on prolonged experience of some particular branch or specialist function of the profession in which he is an acknowledged expert. I can claim no expertise and can draw only on experience of a general nature gained in 25 years since qualification. All but the last four years have been in the field, and it is from this background, devoid of academic or specialist distinction, that I have the privilege of addressing this gathering, and it is fitting that my discourse should be of a general rather than an. academic nature.     

Accreditation of veterinary schools in Australia and New Zealand

Veterinary schools in Australia and New Zealand are assessed for accreditation purposes every six years by the Veterinary Schools Accreditation Advisory Committee (VSAAC), which is a standing committee of the Australasian Veterinary Boards Council (AVBC).1 Prior to undertaking an assessment, VSAAC requests a Self Evaluation Report from the school and subsequently spends a week on site to collect additional information. The committee also takes into consideration other quality assurance procedures within the university and aims for a process that complements other evaluation activities. Internal evaluation procedures within VSAAC are designed to reflect the process and outcomes of each visit and lead to annual revisions of the publication Policies, Procedures and Guidelines publication. The committee has close links with the Royal College of Veterinary Surgeons (RCVS), and there is a routine exchange of observers on all visits in the United Kingdom and Australasia. In recent years VSAAC has become increasingly interested in looking at ways to place greater emphasis on the outcomes of veterinary education and, eventually, to reduce our reliance on input measures. There has been good progress in identifying desirable attributes for veterinary graduates, but further work is needed to establish the reliability of assessment procedures. The Australasian accreditation system is very supportive of recent moves to achieve greater compatibility of veterinary accreditation systems in different parts of the world because we believe it has the potential to assist globalization of animal disease control and veterinary education.     

Work-related stress in the veterinary profession in New Zealand

AIM: To investigate sources of work-related stress in the veterinary profession in New Zealand, perceptions of levels of stress being experienced, and the social support that veterinarians are using to manage work-related stress. METHODS: A postal survey was distributed to 1,907 veterinarians registered with the Veterinary Council of New Zealand (VCNZ). The survey collected information on respondents' age, gender, type and number of people in the workplace, stress levels, depression, suicidal thoughts and attempts, causes of stress and sources of support. RESULTS: Nine hundred and twenty-seven (48.6%) veterinarians returned useable responses. Veterinarians who were retired, working overseas or did not provide information about their type of work were excluded from the analysis, leaving data from 849 (44.5%) veterinarians. Women experienced more work-related stress and depression than men, veterinarians in small animal/mixed practice reported more stress and depression than those in other types of work, and younger veterinarians experienced higher levels of stress than older veterinarians. The main sources of stress were hours worked, client expectations, and unexpected outcomes. Respondents were also stressed by the need to keep up their knowledge and technical skills, and by personal relationships, finances and their expectations of themselves. Most respondents reported that they had good networks of family and friends to help them deal with stress. In general, respondents tended to rely on informal networks such as family and friends, other veterinarians and workmates to provide support. The small proportion of respondents who reported clinical depression or suicidal thoughts or attempts were more likely than respondents in general to have used health professionals, counselling, pastoral/spiritual support and the Vets in Stress phone line, but less likely to have sought support from employers and workmates. CONCLUSIONS: There is a need for a wide range of strategies to manage work-related stress among veterinarians. Sources of stress in the workplace must be identified and strategies developed to control those which present a significant hazard. Strategies may include attention to workloads and working hours, design of work processes, and increasing social support. Training in work-related skills such as communication, conflict management and stress management may be helpful where lack of these skills is contributing to stress. Support services such as help lines and mentor schemes are also available and information about these needs to be more accessible.     

Cross-sectional survey of surgical techniques used to perform dog and cat spays in New Zealand veterinary practice

ABSTRACT

Aims: To describe the variation in surgical techniques used by veterinarians to perform routine dog and cat spays in first-opinion veterinary practice in New Zealand, and how these techniques differed with the number of years since the veterinarian graduated.

Methods: A cross-sectional survey of veterinarians registered to practice in New Zealand was conducted online between 1 April and 30 May 2018. Respondents were asked their year of graduation and about the procedures, they would use to perform a routine spay of a healthy, 5?kg, young adult, female domestic shorthair cat, and a healthy, 20?kg, young adult, female mixed-breed dog. The number of years since graduation was calculated by subtracting the reported year of graduation from 2018.

Results: Overall, 282 respondents provided details about dog spays, and 361 about cat spays, and the median number of years since graduation was 14 (min 0, max 50). Only 54/282 (19.1%) respondents performing dog spays and 43/361 (11.9%) performing cat spays wore a surgical cap, gown, mask, and gloves. For dog spays, 278 (98.6%) respondents used a ventral midline approach and 147 (52.1%) used manual exteriorisation of the uterus. Most used two clamps (168; 59.6%) and used two encircling ligatures (152; 53.9%) for removal of the uterus. For cat spays, 254 (70.4%) respondents used a ventral midline approach and 313 (86.7%) used a spay hook for exteriorising the uterus. Most used two clamps (250; 69.3%) with one encircling ligature (213; 59.0%) for removal of the uterus. Simple interrupted external or intradermal patterns were mostly used for skin closure for both dog and cat spays. For cat spays, the percentage of respondents using the ventral midline approach decreased with increasing years since graduation (p?<?0.001). For both dog and cat spays, the percentage of respondents using two encircling ligatures and transfixation ligation of the uterus, and using a simple continuous suture pattern for the closure of the abdomen, decreased with number of years since graduation (p?<?0.05).

Conclusions and clinical relevance: Veterinarians responding to this survey used a wide range of techniques to perform routine dog and cat spays, some of which were associated with the number of years since graduation. It may be beneficial to provide veterinarians with resources to reflect on their current approaches for performing routine spays. However further research is needed to determine whether any surgical techniques are superior to others.
