Abstract：
OBJECTIVE: To compare the quality of recovery in horses emerging from general anesthesia with or without the assistance of a novel device (recovery-enhancing device [RED]) designed to minimize high-energy falls.
METHODS: 20 mixed-breed horses, between July 1, 2023, and January 24, 2024.
METHODS: A computer-controlled belay system designed to slow the acceleration of a horse during a fall was evaluated in this study. Horses were randomly assigned to 1 of 2 treatment groups: RED (belay, assisted) or FREE (unassisted). An inertia-measuring unit was fitted to all horses and data were live streamed and recorded onto a computer for further analysis. Recoveries were scored using the composite grading scale (CGS; 0 to 100) by 3 independent observers. Two additional unitless recovery scores (RS and RS\'), based on accelerometry values (high accelerations, less desirable), were calculated for each recovery. All the recovery scores were compared between the 2 treatment groups.
RESULTS: Composite grading scale scores were 26 ± 10 and 46 ± 13 in the RED and FREE groups, respectively (P = .001). The RS was 120 ± 79 and 198 ± 34 for the RED and FREE treatment groups, respectively (P = .015). The RS\' was 32 (7 to 50) and 46 (28 to 44) for the RED and FREE treatment groups, respectively (P = .038).
CONCLUSIONS: The RED improves the recovery scores compared with unassisted recoveries. This device may lead to a potential reduction in the number and severity of injuries in horses and personnel involved during the recovery period.

摘要：
目的：比较在有或没有新型装置（恢复增强装置[RED]）的帮助下，从全身麻醉中出来的马匹的恢复质量，该装置旨在最大程度地减少高能量跌倒。
方法：20匹混种马，2023年7月1日至2024年1月24日。
方法：在这项研究中评估了一种计算机控制的保护系统，该系统旨在减慢马在跌倒过程中的加速度。马匹被随机分配到2个治疗组中的1个：红色（belay，辅助)或免费(无辅助)。将惯性测量单元安装到所有马匹上，并将数据实时流式传输并记录到计算机上进行进一步分析。由3名独立观察者使用复合分级量表(CGS;0至100)对恢复进行评分。两个额外的无单位恢复分数(RS和RS')，基于加速度测量值(高加速度，不太可取)，对每个回收率进行了计算。比较2个治疗组的恢复评分。
结果：红色和免费组的综合评分量表得分分别为26±10和46±13，分别(P=.001)。RED和FREE治疗组的RS分别为120±79和198±34，分别(P=.015)。RED和FREE治疗组的RS\'分别为32（7至50）和46（28至44），分别为（P=0.038）。
结论：与无辅助回收相比，RED提高了回收评分。该装置可以导致在恢复期间所涉及的马匹和人员受伤的数量和严重程度的潜在减少。
