Impact of surgical preparatory rinses with isopropyl alcohol or water on perioperative body temperature in pediatric female dogs and cats.

OBJECTIVE: To describe the effects of presurgical preparation with an isopropyl alcohol or water rinse on the perioperative rectal temperature (RT) of puppies and kittens. STUDY DESIGN: Randomized clinical trial. ANIMALS: A total of 48 intact female mixed breed puppies and 43 intact female Domestic Short Hair kittens aged 8-18 weeks. METHODS: All animals were premedicated with intramuscular buprenorphine (0.02 mg kg-1) and acepromazine (0.05 mg kg-1). Anesthesia was induced with intravenous propofol (4 mg kg-1 to effect) for puppies or ketamine (5 mg kg-1) and midazolam (0.25 mg kg-1) for kittens. RT was measured every minute for the first 15 minutes at the beginning of hair/fur removal, then every 5 minutes for 45 minutes (dogs) and 35 minutes (cats). All animals were prepared for surgery using a 1.6% chlorhexidine solution, then rinsed with either isopropyl alcohol (group CA) or water (group CW). RESULTS: Mean RT difference between the groups was not significant at any time point. The mean RT at 45 minutes for dogs was 35.9 °C and 36.0 °C in groups CA and CW, respectively (p = 0.74). The mean RT at 35 minutes for cats was 35.1 °C in both groups (p = 0.84). CONCLUSIONS AND CLINICAL RELEVANCE: The use of either water or alcohol as a rinsing agent results in the same degree of perioperative temperature change. Other factors that contribute to perioperative hypothermia should be considered when choosing between these rinsing agents in surgical preparation of pediatric and small animals.

Assessment of body weight for age determination in kittens.

OBJECTIVES: The objective of this study was to assess the utility of using body weight for age determination in kittens. METHODS: Medical records were reviewed for serial body weight measurements collected from neonatal kittens (up to 8 weeks of age) from a breeding colony of specific pathogen-free domestic shorthair cats and for single-point body weight measurements of privately owned pediatric kittens (6-20 weeks of age) presenting for elective sterilization. Body weights were compared with known dates of birth and age assessed by dental eruption in combination with developmental characteristics. RESULTS: The coefficient of determination (R2) between age and body weight in longitudinally sampled neonatal kittens was 0.88, while that for pediatric kittens sampled at a single time point was 0.54. Among neonatal kittens, predicted age based on the 1 lb (0.45 kg) of body weight gain per month of age guideline corresponded to within 1 week of actual age for 243 (98.8%), 234 (95.1%), 203 (82.5%) and 191 (77.6%) kittens at 2, 4, 6 and 8 weeks of age, respectively. Among pediatric kittens, predicted age based on this guideline corresponded to within 1 week of actual age for 24 (77.4%), 411 (67.5%), 170 (57.0%), 96 (46.6%), 23 (28.8%), 15 (27.8%), one (25%) and five (17.9%) kittens at 6, 8, 10, 12, 14, 16, 18 and 20 weeks, respectively. CONCLUSIONS AND RELEVANCE: Body weight was an effective means of predicting age in kittens through 10 weeks of age. Factors other than body weight should be considered when estimating kitten age beyond that time point.

Amniotic membrane transplantation for ligneous conjunctivitis in a doberman.

An approximately 2-year-old female Doberman Pinscher was referred for the evaluation of bilateral, chronic proliferative conjunctivitis. Ophthalmic examination revealed bilateral thick, opaque pseudomembranes originating from the conjunctivae that prevented visualization of the cornea and interior structures of the eye. Histopathological findings of biopsies of the pseudomembranes were consistent with ligneous conjunctivitis. Serum plasminogen activity levels were within the normal range. Treatment with topical and systemic anti-inflammatory and immunosuppressive drugs did not improve the conjunctival lesions. The pseudomembranes were surgically excised, and the conjunctival surfaces were reconstructed with amniotic membrane. At final re-examination two years postsurgery, there was no evidence of recurrence of the pseudomembranes. To the authors' knowledge, this is the first reported case of the successful treatment of canine ligneous conjunctivitis with amniotic membrane transplantation.

Development and validation of a probe hybridization reverse-transcription quantitative PCR for detection of mamastrovirus 2 in domestic cats.

Astroviruses are viral pathogens that have been associated with enteric and neurologic disease in a variety of species. The domestic cat is a prominent host, with reports of astroviral infection being both highly prevalent and widely distributed in the feline population. Despite the potential for inducing significant disease, especially within shelter environments, there is currently only one reliable method of detection: standard reverse-transcription PCR using pan-astrovirus degenerate primers (consensus RT-PCR) with product sequencing. Unfortunately, this process is relatively slow and costly. Quantitative real-time PCR (qPCR) represents an efficient, economical alternative, with the added benefit of viral load quantification. We developed a RT-qPCR assay using probe hybridization technique to detect conserved regions of mamastrovirus 2 extracted from fecal samples of domestic cats. Known positive and negative samples were tested, and results were compared with gold standard consensus RT-PCR and sequencing. A standard curve was employed to determine limits of detection. In order to assess analytic specificity, we tested several additional samples that had been collected from non-felid species and were known to contain non-target astroviruses. Discrepant results between consensus RT-PCR and RT-qPCR testing were further analyzed with a validation RT-PCR assay, using mamastrovirus 2-specific primers. Our probe hybridization RT-qPCR assay is reliable and effective for the detection of mamastrovirus 2. This assay will allow rapid, affordable detection and facilitate further research on astroviral infection within domestic cats.

Determination of the diversity of astroviruses in feces from cats in Florida.

Astroviruses are small, nonenveloped RNA viruses that have been linked to numerous diseases in a variety of species, including enteric disease in humans and cheetahs. Species Mamastrovirus 2, previously known as feline astrovirus, has been isolated from the feces of domestic cats and cheetahs. A total of 122 cat fecal samples from Alachua County, FL Animal Services and the Veterinary Community Outreach Program at the University of Florida were analyzed, and 35 contained astroviral RNA that was amplified and identified using consensus RT-PCR and sequence analysis. Using phylogenetic analysis, 19 of the astroviral sequences were identified as Mamastrovirus 2, making it the most prevalent astrovirus in this population. Three samples were identified as an astrovirus similar to viruses previously identified in foxes in The Netherlands and a cat in California, and one was similar to a bat astrovirus. One astroviral sequence was identified as an Avastrovirus. Although a causative relationship between mamastroviruses and enteric disease in cats has yet to be established, it is clear that mamastroviruses are prevalent, and an understanding of prevalence of astroviral types may help direct future test development.

Factors that Influence Intake to One Municipal Animal Control Facility in Florida: A Qualitative Study.

This qualitative study identified a study area by visualizing one year of animal intake from a municipal animal shelter on geographic information systems (GIS) maps to select an area of high stray-dog intake to investigate. Researchers conducted semi-structured interviews with residents of the selected study area to elucidate why there were high numbers of stray dogs coming from this location. Using grounded theory, three themes emerged from the interviews: concerns, attitudes, and disparities. The residents expressed concerns about animal welfare, personal safety, money, and health. They held various attitudes toward domestic animals in the community, including viewing them as pets, pests, or useful commodities (products). Residents expressed acceptance as well as some anger and fear about the situation in their community. Interviewees revealed they faced multiple socioeconomic disparities related to poverty. Pet abandonment can result when pet owners must prioritize human needs over animal needs, leading to increased shelter intake of stray dogs. Community-specific strategies for reducing local animal shelter intake should address the issue of pet abandonment by simultaneously targeting veterinary needs of animals, socioeconomic needs of residents, and respecting attitude differences between residents and shelter professionals.

The Association of Shelter Veterinarians' 2016 Veterinary Medical Care Guidelines for Spay-Neuter Programs.

As community efforts to reduce the overpopulation and euthanasia of unwanted and unowned cats and dogs have increased, many veterinarians have increasingly focused their clinical efforts on the provision of spay-neuter services. Because of the wide range of geographic and demographic needs, a wide variety of spay-neuter programs have been developed to increase delivery of services to targeted populations of animals, including stationary and mobile clinics, MASH-style operations, shelter services, community cat programs, and services provided through private practitioners. In an effort to promote consistent, high-quality care across the broad range of these programs, the Association of Shelter Veterinarians convened a task force of veterinarians to develop veterinary medical care guidelines for spay-neuter programs. These guidelines consist of recommendations for general patient care and clinical procedures, preoperative care, anesthetic management, surgical procedures, postoperative care, and operations management. They were based on current principles of anesthesiology, critical care medicine, infection control, and surgical practice, as determined from published evidence and expert opinion. They represent acceptable practices that are attainable in spay-neuter programs regardless of location, facility, or type of program. The Association of Shelter Veterinarians envisions that these guidelines will be used by the profession to maintain consistent veterinary medical care in all settings where spay-neuter services are provided and to promote these services as a means of reducing sheltering and euthanasia of cats and dogs.

Effects of anesthetic induction with a benzodiazepine plus ketamine hydrochloride or propofol on hypothermia in dogs undergoing ovariohysterectomy.

OBJECTIVE: To assess the effect of anesthetic induction with a benzodiazepine plus ketamine or propofol on hypothermia in dogs undergoing ovariohysterectomy without heat support. ANIMALS: 23 adult sexually intact female dogs undergoing ovariohysterectomy. PROCEDURES: Baseline rectal temperature, heart rate, and respiratory rate were recorded prior to premedication with buprenorphine (0.02 mg/kg, IM) and acepromazine (0.05 mg/kg, IM). Anesthesia was induced with midazolam or diazepam (0.25 mg/kg, IV) plus ketamine (5 mg/kg, IV; n = 11) or propofol (4 mg/kg, IV; 12) and maintained with isoflurane in oxygen. Rectal temperature was measured at hospital intake, prior to premedication, immediately after anesthetic induction, and every 5 minutes after anesthetic induction. Esophageal temperature was measured every 5 minutes during anesthesia, beginning 30 minutes after anesthetic induction. After anesthesia, dogs were covered with a warm-air blanket and rectal temperature was measured every 10 minutes until normothermia (37°C) was achieved. RESULTS: Dogs in both treatment groups had lower rectal temperatures within 5 minutes after anesthetic induction and throughout anesthesia. Compared with dogs that received a benzodiazepine plus ketamine, dogs that received a benzodiazepine plus propofol had significantly lower rectal temperatures and the interval from discontinuation of anesthesia to achievement of normothermia was significantly longer. CONCLUSIONS AND CLINICAL RELEVANCE: Dogs in which anesthesia was induced with a benzodiazepine plus propofol or ketamine became hypothermic; the extent of hypothermia was more profound for the propofol combination. Dogs should be provided with adequate heat support after induction of anesthesia, particularly when a propofol-benzodiazepine combination is administered.

Cardiopulmonary Effects of Laparoscopic Ovariectomy of Variable Duration in Cats.

OBJECTIVE: To evaluate the cardiopulmonary effects of low-pressure (6 mmHg) peritoneal insufflation of varying duration in healthy cats during ovariectomy (OVE). STUDY DESIGN: Prospective, randomized study. ANIMALS: Female cats (n = 24). METHODS: After anesthesia induction, cats had short (Short LAP; n = 8) or long duration (Long LAP; n = 8) laparoscopic ovariectomy, or Open OVE (Open; n = 8) for comparison. Hemodynamic and pulmonary measurements were recorded after induction of anesthesia (T0), 5 minutes after abdominal insufflation had reached 6 mmHg of pressure (T1), after the 2nd ovary had been resected (T2), after abdominal decompression (T3), and at the end of anesthesia, after abdominal closure (T4). Hemodynamic and pulmonary variables were compared between groups. RESULTS: Low-pressure abdominal insufflation caused cardiopulmonary changes in cats. At T1 and T2, Long LAP and Short LAP caused a significant change in PvCO2 and RC when compared with Open. During T3, RC was lower only in Long LAP. At T2, there was decrease in SV, but not CO for Long LAP when compared with Open. CONCLUSIONS: Duration of insufflation was associated with worsening of negative cardiopulmonary effects; however, these effects were reversible and resolved by the end of the procedure.

Effects of maropitant, acepromazine, and electroacupuncture on vomiting associated with administration of morphine in dogs.

OBJECTIVE: To evaluate effects of maropitant, acepromazine, and electroacupuncture on morphine-related signs of nausea and vomiting in dogs and assess sedative effects of the treatments. DESIGN: Randomized controlled clinical trial. ANIMALS: 222 dogs. PROCEDURES: Dogs received 1 of 6 treatments: injection of saline (0.9% NaCl) solution, maropitant citrate, or acepromazine maleate or electroacupuncture treatment at 1 acupoint, 5 acupoints, or a sham acupoint. Morphine was administered after 20 minutes of electroacupuncture treatment or 20 minutes after injectable treatment. Vomiting and retching events and signs of nausea and sedation were recorded. RESULTS: Incidence of vomiting and retching was significantly lower in the maropitant (14/37 [37.8%]) group than in the saline solution (28/37 [75.7%]) and sham-acupoint electroacupuncture (32/37 [86.5%]) groups. The number of vomiting and retching events in the maropitant (21), acepromazine (38), 1-acupoint (35), and 5-acupoint (34) groups was significantly lower than in the saline solution (88) and sham-acupoint electroacupuncture (109) groups. Incidence of signs of nausea was significantly lower in the acepromazine group (3/37 [8.1%]) than in the sham-acupoint group (15/37 [40.5%]). Mean nausea scores for the saline solution, maropitant, and sham-acupoint electroacupuncture groups increased significantly after morphine administration, whereas those for the acepromazine, 1-acupoint electroacupuncture, and 5-acupoint electroacupuncture groups did not. Mean sedation scores after morphine administration were significantly higher in dogs that received acepromazine than in dogs that received saline solution, maropitant, and sham-acupoint electroacupuncture treatment. CONCLUSIONS AND CLINICAL RELEVANCE: Maropitant treatment was associated with a lower incidence of vomiting and retching, compared with control treatments, and acepromazine and electroacupuncture appeared to prevent an increase in severity of nausea following morphine administration in dogs.

Comparison of surgical variables in cats undergoing single-incision laparoscopic ovariectomy using a LigaSure or extracorporeal suture versus open ovariectomy.

OBJECTIVE: To evaluate the applicability of single-incision laparoscopic ovariectomy (SILOVE) in cats using a single-incision laparoscopic port (SILP); to compare surgical time, complications, and postoperative pain after SILOVE using a LigaSure (SILOVE-LS) or extracorporeal suture (SILOVE-ECS), and open ovariectomy (open-OVE). STUDY DESIGN: Randomized, blinded, prospective study. ANIMALS: Healthy, domestic female cats (n = 24). METHODS: Cats underwent physical examination, packed cell volume, total solids and blood urea nitrogen analysis. Cats were randomly assigned to 1 of 3 groups: SILOVE-LS (n = 8), SILOVE-ECS (8) or open-OVE (8). Surgical time, complications, and postoperative pain scores were recorded. RESULTS: Single-incision laparoscopic ovariectomy was successful in (n = 8) SILOVE-LS cats and (n = 5) SILOVE-ECS cats. Surgical time was significantly longer for the SILOVE-ECS group compared with the SILOVE-LS (P < .0001) and open-OVE (P < .0001) groups, which were not different (P = .55). Complications were more frequent in the SILOVE-ECS group and removal of the SILP was required to complete ovariectomy in 3 cats. Cumulative 4-hour pain scores were not different between groups. CONCLUSIONS: Single-incision laparoscopic ovariectomy using a SILP is a feasible method for OVE in cats. Single-incision laparoscopic ovariectomy using an extracorporeal suture is more time consuming and associated with more complications than either the SILOVE-LS or open-OVE methods.

Evaluation of medetomidine, ketamine and buprenorphine for neutering feral cats.

A combination of medetomidine (M, 100 µg/kg), ketamine (K, 10 mg/kg) and buprenorphine (B, 10 µg/kg), administered by intramuscular injection, was evaluated for spaying and castration (neutering) of feral cats (n = 101). Eleven animals (11%) required supplemental anesthesia (isoflurane by mask) to maintain an adequate plane of surgical anesthesia. Atipamezole (A, 125 µg/kg) was administered subcutaneously at the completion of surgery. All cats recovered from surgery and were released the following day. A hemoglobin saturation (SpO(2)) value of < 95% was recorded at least once during anesthesia in all cats. This MKB combination can be used in a feral cat sterilization clinic, but isoflurane supplementation may be necessary. Further research is indicated to determine the clinical significance of the low SpO(2) values associated with this anesthetic regimen.

The role of veterinary medicine in an interdisciplinary family health course.

First-year students from five health professions colleges engaged in a team-taught interdisciplinary family health course located in a community-based setting. This descriptive account of their experiences describes the implications of interdisciplinary education for student learning with an emphasis on the health care concerns of the volunteer families and their companion animals that participated in the Interdisciplinary Family Health course. The authors underscore the potential of interdisciplinary course work for the enrichment of the educational process, with collaboration between veterinary and other health professions, including the disciplines of medicine, nursing, nutrition, pharmacy, physical therapy, dental, social work, and the larger community, by providing an emphasis on family health and companion-animal care.

Education of global veterinarians.

In 2003, the University of Florida (UF) College of Veterinary Medicine (CVM) created an Office of International Programs (OIP) in response to one of ten initiatives of the UF Strategic Plan: internationalization of the curriculum. The OIP has developed coursework that provides students with an opportunity for international exposure during the veterinary curriculum at three levels. In Level 1 (on campus) students can participate in a seminar series in global health: www.ufglobalhealth.org. This is an elective course offered to professional students at the UF Health Science Center (Dentistry, Medicine, Pharmacy, Public Health, and Veterinary Medicine). In Level 2 (abroad), students can participate in structured study abroad programs under the supervision of UF faculty and international scholars from collaborative institutions abroad. In Level 3 (on campus and abroad), students can participate in a certificate program in international veterinary medicine. This is a 15-credit program, parallel to the veterinary curriculum. By offering courses on campus and abroad, we want to empower the curriculum with a global perspective of the veterinary profession, as well as with a humanist education that can help students recognize the importance of respect for cultural differences and the reasons for different degrees of development and growth in the world. In addition, this paper presents the need for veterinary medicine and other disciplines in the health sciences to communicate with other disciplines in the social sciences and natural sciences to create development practitioners equipped with cross-disciplinary knowledge and skills needed to formulate, implement and evaluate solutions aimed at breaking the cycle of poverty and disease in low income societies. Finally, this paper makes a call to the American Veterinary Medical Association Council on Education to assess the need to recognize the importance of internationalization of the veterinary curriculum as a key standard for accreditation of colleges or schools of veterinary medicine.

Comparison between analgesic effects of buprenorphine, carprofen, and buprenorphine with carprofen for canine ovariohysterectomy.

OBJECTIVE: To compare the analgesic effects of buprenorphine, carprofen, and their combination in dogs undergoing ovariohysterectomy. STUDY DESIGN: Prospective, randomized blinded clinical study. ANIMALS: 60 dogs. METHODS: Treatments were buprenorphine 0.02 mg kg(-1), intramuscularly (IM) (group B); carprofen 4 mg kg(-1), subcutaneously (SC) (group C); or a combination of both (group CB). Anesthesia was induced with propofol and maintained with isoflurane. A Dynamic Interactive Visual Analog Scale (DIVAS, 0-100 mm) and the Glasgow Composite Pain Scale (GCMPS, 0-24) were used to evaluate comfort and sedation at baseline, 2, 4, 6, and 24 hours after extubation. Rescue analgesia was provided with buprenorphine (0.02 mg kg(-1)). Wound swelling measurements (WM) and a visual inflammation score (VIS) of the incision were made after surgery and 2, 4, 6, and 24 hours later. p < 0.05 was considered significant. RESULTS: Group C required more propofol (5.0 +/- 1.4 mg kg(-1)) compared with B (3.3 +/- 1.1 mg kg(-1)) and CB (3.2 +/- 0.7 mg kg(-1)); respectively, p = 0.0002 and 0.0001. Rescue analgesia was required in nine dogs. B had a higher GCMPS and DIVAS III score at 6 hours (2.6 +/- 2.5) and (23 +/- 22.5 mm) compared with C (1.0 +/- 1.3, 6 +/- 7.3 mm) and CB (1.5 +/- 1.4, 8 +/- 10.7 mm); respectively, p = 0.02 and 0.006. Group C had a lower sedation score at 2 hours (43 +/- 23.6 mm) compared with B (68 +/- 32.1 mm) and BC (69 +/- 22.1 mm); respectively, p = 0.03 and 0.004. Group B had a higher WM score at 2 hours (3 +/- 0.8 mm) compared with C (2 +/- 0.6 mm) p = 0.01 and at 6 hours (3 +/- 1 mm) compared with C (2 +/- 0.8 mm) and CB (2 +/- 0.8 mm); respectively, p = 0.01 and 0.008. VIS was not different between groups. CONCLUSION AND CLINICAL RELEVANCE: All treatments provided satisfactory analgesia for the first 6 hours and at 24 hours. C and CB pain score and WS were superior to B at 6 hours. No superior analgesic effect was noted when the drugs were combined.
