“…With regular use, it is possible that the time to place the SGAD may be reduced further, and recorded times in this study were increased because they included observing a waveform on the capnograph (18). Securing an airway in a reasonable time allows management of hypoventilation and control of PaCO 2 and PaO 2 .…”

“…Both authors involved in device placement completed an online training course available on the manufacturer’s website as well as successfully performing several SGAD placements in two rabbits scheduled for euthanasia. During product development, the device designer suggested that a degree of experience is necessary for optimal placement in combination with capnograph trace evaluation (18). High fresh gas flow rates, large sampling chambers, and slow rise times can distort capnograph traces, particularly in smaller animals, though the gas flow rate used was comparable to that previously described in rabbits (1.5–2 L min −1 ), a small sample chamber (dead space volume of 1 mL) was used and the rise time of the capnograph is reported as <60 ms (for 10–90% step change).…”

“…However, lingual cyanosis, gastric tympany, and an incomplete airway seal have been reported with the use of human SGAD in rabbits (8, 12, 17). Recently, a rabbit-specific device (v-gel, Docsinnovent Ltd., London, UK) has been developed, which may help reduce these complications (6, 18). …”

IntroductionAchieving a secure airway in rabbits is generally considered more difficult than in cats or dogs. Their relatively large tongue, small oropharyngeal cavity and glottis limit direct visualization. A rabbit-specific supraglottic airway device (SGAD) may offer benefits over blind orotracheal intubation.Animals and methodsFifteen adult New Zealand white rabbits were randomized to SGAD or orotracheal intubation (ETT). All animals were sedated with dexmedetomidine (0.1 mg kg−1 IM) and midazolam (0.5 mg kg−1 IM), followed by induction with alfaxalone (0.3 mg kg−1 IV). Two CT scans of the head and neck were performed, following sedation and SGAD/ETT placement. The following were recorded: time to successful device insertion, smallest cross-sectional airway area, airway sealing pressure, and histological score of tracheal tissue. Data were analyzed with a Mann–Whitney test.ResultsTwo rabbits were excluded following failed ETT. Body masses were similar [ETT; n = 6, 2.6 (2.3–4.5) kg, SGAD; n = 7, 2.7 (2.4–5.0) kg]. SGAD placement was significantly faster [33 (14–38) s] than ETT [59 (29–171) s]. Cross-sectional area (CSA) was significantly reduced from baseline [12.2 (6.9–3.4) mm2] but similar between groups [SGAD; 2.7 (2.0–12.3) mm2, ETT; 3.8 (2.3–6.6) mm2]. In the SGAD group, the device tip migrated into the laryngeal vestibule in 6/7 rabbits, reducing the CSA. ETT airway seals were higher [15 (10–20) cmH2O], but not significant [SGAD; 5 (5–20) cmH2O, p = 0.06]. ETT resulted in significantly more mucosal damage [histological score 3.3 (1.0–5.0)], SGAD; 0.67 (0.33–3.67).ConclusionThe SGAD studied was faster to place and caused less damage than orotracheal intubation, but resulted in a similar CSA.

PURPOSE:To evaluate the applicability and airway management capacity of v-gel ® and Cobra PLA in rabbit anaesthesia during assisted (AV) or controlled ventilation (CV). METHODS:This study was carried out in 44 adult New Zealand white rabbit. Baseline arterial pH, PaCO 2 and PaO 2 values were recorded. Anaesthesia was induced with 5 mg/kg xylasine and 35 mg/kg ketamine HCI combination. AV rabbits were assigned as;control (CG-AV; n=5), LMA (LMA-AV; n=5), cobra PLA (PLA-AV; n=5) and v-gel (v-gelAV; n=5). Rabbits have CV were also assigned as; ET (ET-CV; n=6), LMA (LMA-CV; n=6), cobraPLA (PLA-CV; n=6) and v-gel (v-gelCV; n=6). All measurements were repeated 1st, 5th, 15th and 30th mins during anaesthesia. RESULTS:The less insertion time, number of attempt and complications are recorded in v-gel applied rabbits compared to other apparatus. For arterial pH values significant differences are recorded in especially at 15th and 30th min between groups of CV (p<0.005 or p<0.001). All groups had similar results with each other during anaesthesia for PaCO 2 except for LMA-CV group. CONCLUSION:The v-gel may be used as airway device in rabbit anaesthesia undergoing AV or CV and also can be a suitable alternative to endotracheal tubes and laryngeal mask airway.

“…An additional option is to use commercially available supraglottic airway devices. [81][82][83][84][85][86][87] When used, airway management devices should be properly fitted and carefully secured in place. Tape or ties made from plastic tubing, gauze, or other materials are acceptable for this purpose.…”

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, MASHstyle 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.
