Abstract

Objective: To assess the v-gel Advanced Dog supraglottic airway device (SGAD) safety and efficacy compared to a high-volume, low-pressure endotracheal tube (ETT).

Methods: In a prospective randomized study, 30 client-owned mesocephalic canine patients (American Society of Anesthesiologists physical status I or II, scheduled for elective surgery) were to be enrolled and assigned to the SGAD or ETT group (15 SGAD; 15 ETT) by blocked randomization. Endotracheal tube cuffs were inflated to 25 cm H2O with a cuff inflator. The primary outcome was anesthetic circuit pressure decrease (leak) of inspiratory air at escalating anesthetic system pressures, tested at 0, 10, 15, and 20 minutes after airway device placement.

Results: Due to safety concerns, the study was terminated after 6 patients in the SGAD group failed leak pressure testing under 20 cm H2O at all time points. Thirteen canines (6 SGAD, 7 ETT) were enrolled from September through October 2023. The risk of leaking for the SGAD group was significantly higher than that of the ETT group at 12 cm H2O (P = .005) and at 16 cm H2O (P = .001). There were no perioperative or postoperative adverse events or significant differences in characteristics between airway device groups except that the risk for not requiring manipulations to obtain and maintain an effective airway for the SGAD group was 67% less (relative risk, 0.33; exact 90% CI, 0.06 to 0.74) than that of the ETT group.

Conclusions: The SGAD, but not ETT, failed leak pressure testing < 20 cm H2O.

Clinical relevance: The v-gel Advanced Dog SGAD was not safe to deliver inhalant anesthetics due to the device failing leak pressure testing under 20 cm H2O.

在健康犬麻醉中，v-gel高级犬的气道密封效果不如气管内插管。

目的：比较v-gel高级犬声门上气道装置（SGAD）与大容量、低压气管插管（ETT）的安全性和有效性。方法：在一项前瞻性随机研究中，30例客户拥有的中脑犬患者（美国麻醉医师协会身体状态I或II，计划择期手术）被纳入并分配到SGAD或ETT组(SGAD组15例；15个ETT)通过阻塞随机化。气管插管袖口用袖口充气器充气至25 cm H2O。主要结果是麻醉回路压力降低（吸入空气泄漏），麻醉系统压力升高，在气道装置放置后0,10,15和20分钟进行测试。结果：出于安全考虑，SGAD组6例患者在所有时间点20 cm H2O下的泄漏压力测试失败后，研究终止。从2023年9月到10月，共招募了13只犬（6只SGAD， 7只ETT）。在12 cm H2O （P = 0.005）和16 cm H2O （P = 0.001）时，SGAD组的渗漏风险显著高于ETT组。除SGAD组无需操作即可获得和维持有效气道的风险低67%外，两组间无围手术期或术后不良事件或显著差异(相对风险，0.33；确切的90% CI（0.06 ~ 0.74）高于ETT组。结论：在< 20 cm H2O的泄漏压力测试中，SGAD失败，而ETT不失败。临床相关性：由于v-gel Advanced Dog SGAD在20 cm H2O下的泄漏压力测试失败，因此该设备不安全用于输送吸入麻醉剂。

期刊介绍： The American Journal of Veterinary Research supports the collaborative exchange of information between researchers and clinicians by publishing novel research findings that bridge the gulf between basic research and clinical practice or that help to translate laboratory research and preclinical studies to the development of clinical trials and clinical practice. The journal welcomes submission of high-quality original studies and review articles in a wide range of scientific fields, including anatomy, anesthesiology, animal welfare, behavior, epidemiology, genetics, heredity, infectious disease, molecular biology, oncology, pharmacology, pathogenic mechanisms, physiology, surgery, theriogenology, toxicology, and vaccinology. Species of interest include production animals, companion animals, equids, exotic animals, birds, reptiles, and wild and marine animals. Reports of laboratory animal studies and studies involving the use of animals as experimental models of human diseases are considered only when the study results are of demonstrable benefit to the species used in the research or to another species of veterinary interest. Other fields of interest or animals species are not necessarily excluded from consideration, but such reports must focus on novel research findings. Submitted papers must make an original and substantial contribution to the veterinary medicine knowledge base; preliminary studies are not appropriate.
