To examine the association between objective and subjective descriptors used for assessing recovery quality in horses after anaesthesia.
Prospective clinical study.
Two hundred and seventy-six equids (110 mares, 85 entire males and 81 geldings), ASA 1-5, weighing 50-850 kg and aged 1 month - 25 years.
Recoveries after general anaesthesia were assisted with head and tail ropes by two anaesthetists. One scored dichotomous objective descriptors (DOD) of recovery. Two dichotomous objective scales (DOS) were then generated from those descriptors. The same individual also scored overall recovery quality using a visual analogue scale (VAS). The second anaesthetist scored recovery (good or bad) using a dichotomous subjective scale (DSS). Each DOD, the DSS and VAS were compared with each other using Pearson's chi-square test. DOSs were compared to the DSS using Wilcoxon's test and to the VAS using a Spearman's correlation test.
Most DODs were associated (p < 0.05) with DSS and VAS. The DSS was not associated with resting/not resting in sternal recumbency (p = 0.535) nor with the time spent in sternal recumbency (p = 0.09). VAS and DSS scores were strongly associated (p < 0.0001). The two DOSs were in agreement with DSS (p < 0.0001) and negatively correlated to VAS (r(1)(2) = 0.38, r(2)(2) = 0.34, respectively, p-value <0.0001).
Objective descriptors were linked closely with the subjective evaluations of recovery quality except for the presence or absence of a sternal recumbency phase and its duration.
These components may not be essential in recovery scoring systems. The DOS were in agreement with DSS and VAS and could be a useful tool for further studies on recoveries.
研究用于评估马匹麻醉后恢复质量的客观指标与主观描述之间的关联。
前瞻性临床研究。
276匹马（110匹母马、85匹成年公马和81匹去势公马），美国麻醉医师协会（ASA）分级为1 - 5级，体重50 - 850千克，年龄1个月至25岁。
全身麻醉后的苏醒由两名麻醉师通过头部和尾部绳索辅助进行。一人对恢复的二分客观指标（DOD）进行评分。然后从这些指标生成两个二分客观量表（DOS）。同一个人还使用视觉模拟量表（VAS）对整体恢复质量进行评分。第二名麻醉师使用二分主观量表（DSS）对恢复情况（好或差）进行评分。使用Pearson卡方检验对每个DOD、DSS和VAS进行相互比较。使用Wilcoxon检验将DOS与DSS进行比较，并使用Spearman相关检验将DOS与VAS进行比较。
大多数DOD与DSS和VAS相关（p < 0.05）。DSS与侧卧休息/不休息无关（p = 0.535），也与侧卧的时间无关（p = 0.09）。VAS和DSS评分密切相关（p < 0.0001）。两个DOS与DSS一致（p < 0.0001），并且与VAS呈负相关（r(1)(2) = 0.38，r(2)(2) = 0.34，p值均<0.0001）。
除了是否存在侧卧阶段及其持续时间外，客观指标与恢复质量的主观评估密切相关。
这些因素在恢复评分系统中可能并非必不可少。DOS与DSS和VAS一致，可能是进一步研究恢复情况的有用工具。
