Cross-sectional survey of anaesthesia and analgesia protocols used to perform routine canine and feline ovariohysterectomies.

OBJECTIVE: To collect baseline descriptive data on the anaesthesia and analgesia protocols used by New Zealand veterinarians in first-opinion practice when performing routine canine and feline ovariohysterectomies. STUDY DESIGN: Cross-sectional survey. ANIMALS: Not applicable. METHODS: An online survey was conducted asking respondents for: 1) preoperative patient assessment; 2) preanaesthetic medication and induction drugs used; 3) anaesthesia maintenance drug choices and monitoring equipment used; and 4) postoperative analgesia drug selections and monitoring for ovariohysterectomy performed in healthy adult dogs and cats. RESULTS: The survey was completed by 472 veterinarians, of whom 282 provided responses for canine ovariohysterectomy and 361 provided responses for feline ovariohysterectomy. Approximately 23% of canine ovariohysterectomies and 13% of feline ovariohysterectomies had preanaesthetic bloodwork performed. There were 74 unique premedication/induction drug combinations reported for canine ovariohysterectomies and 94 for feline ovariohysterectomies. The most commonly used drug combinations were acepromazine, morphine ± propofol and butorphanol, ketamine and medetomidine for canine and feline ovariohysterectomies respectively. Most animals were intubated, and anaesthesia was maintained with isoflurane in oxygen. Use of intravenous catheters, fluid administration, heat support, and monitoring equipment varied. There were 41 unique postoperative analgesia drug combinations reported for canine ovariohysterectomies and 20 for feline ovariohysterectomies. Canine ovariohysterectomies were most commonly administered injectable opioids on the day of surgery followed by 3 days of oral non-steroidal anti-inflammatory drugs (NSAIDs), whereas feline ovariohysterectomies were usually administered a single injection of an opioid or NSAID or both on the day of surgery. Most animals were seen within 7-10 days for re-examination and/or suture removal. CONCLUSIONS AND CLINICAL RELEVANCE: Veterinarians use a wide range of anaesthesia and analgesia protocols for routine ovariohysterectomies. Further research is needed comparing the safety and efficacy of commonly used protocols to determine whether there are opportunities to improve the level of patient welfare.

Experience of Practicing Veterinarians with Supervising Final-Year Students and New Graduates in Performing Desexing Surgeries.

With increasing pressure on university teaching hospital caseloads, veterinary students are increasingly being taught basic desexing skills during their final-year extramural rotations or as new graduates in practice. A cross-sectional survey of New Zealand veterinarians was conducted to elicit information about their experiences supervising these cohorts. Of the 162 respondents who had supervised at least one final-year veterinary student, only 95 (58.6%) allowed students to perform desexing surgeries and the most common procedures they allowed students to perform were cat neuters (96%) followed by cat spays (64%), dog neuters (63%), and dog spays (24%). The time needed to supervise students, the liability of students operating on client-owned animals, and students' poor basic instrument, tissue, and suture handling skills were cited as major deterrents. Breaks in sterility and dropped pedicles were the most frequently reported complications, although these still occurred only occasionally or rarely. Of the 101 respondents who had supervised at least one new graduate, all but one provided surgical mentoring. It took an average of 3.3 dog neuters, 8 dog spays, 2.4 cat neuters, and 4.7 cat spays before respondents were comfortable letting new graduates perform surgery unassisted. Respondents generally expected new graduates to perform dog spays in under 60 minutes, cats spays and dog neuters in under 30 minutes, and cat neuters in under 10 minutes. Although most respondents agreed that students needed more hands-on experience with live animal surgery, the main clinical skills deficiencies identified were ones that could easily be trained and practiced on simulated models.

Guidelines for Implementing a Low-Cost Volunteer Desexing Skills Training Program for Veterinary and Veterinary Technology Students.

Although desexing surgeries are considered a core clinical skill for small animal veterinary practice, it can be challenging for veterinary schools to provide students with adequate training opportunities in the traditional curriculum. At the Massey University School of Veterinary Science, we recently established an innovative extracurricular volunteer program designed to have students teaching other students how to perform different elements of desexing procedures as they progress through their degree. This program includes administrative and assistant roles for first-year students (responsible for client communication, patient restraint, and medical record keeping), physical exam and recovery roles for second-year students (responsible for assessing patient fitness for surgery, drawing up anesthetic drugs, and monitoring patients in recovery), anesthesia and neuter surgeon roles for third-year students (responsible for inducing, preparing, and monitoring spay patients and performing cat neuter surgeries), and spay surgeon roles for fourth- and fifth-year students (responsible for performing cat spay surgeries, discharging patients, and following up with clients to monitor recovery). This program has been successful in improving student confidence and competence while also providing a valuable low-cost desexing service to the community. In this article, we discuss the practical considerations and processes involved in implementing this program, including mapping the existing surgical curriculum, recruiting patients, setting up the surgical facilities, purchasing equipment and supplies, establishing standard operating procedures, developing training materials, maintaining clinic records, and monitoring program outcomes. These resources can serve as guidelines for other veterinary schools looking to expand desexing surgery training opportunities for students.
