Pain assessment guides decision-making in pain management and improves animal welfare. We aimed to investigate the reliability and validity of the UNESP-Botucatu cattle pain scale (UCAPS) and the cow pain scale (CPS) for postoperative pain assessment in (Angus) and (Nelore) bulls after castration.
Ten Nelore and nine Angus bulls were anaesthetised with xylazine-ketamine-diazepam-isoflurane-flunixin meglumine. Three-minute videos were recorded at -48 h, preoperative, after surgery, after rescue analgesia and at 24 h. Two evaluators assessed 95 randomised videos twice one month apart.
There were no significant differences in the pain scores between breeds. Intra and inter-rater reliability varied from good (>0.70) to very good (>0.81) for all scales. The criterion validity showed a strong correlation (0.76-0.78) between the numerical rating scale and VAS versus UCAPS and CPS, and between UCAPS and CPS (0.76). The UCAPS and CPS were responsive; all items and total scores increased after surgery. Both scales were specific (81-85%) and sensitive (82-87%). The cut-off point for rescue analgesia was >4 for UCAPS and >3 for CPS.
The UCAPS and CPS are valid and reliable to assess postoperative pain in and bulls.
疼痛评估指导疼痛管理中的决策制定并改善动物福利。我们旨在研究圣保罗州立大学-博图卡图牛疼痛量表(UCAPS)和奶牛疼痛量表(CPS)在安格斯公牛和内洛尔公牛去势术后疼痛评估中的可靠性和有效性。
用赛拉嗪-氯胺酮-地西泮-异氟烷-氟尼辛葡甲胺对10头内洛尔公牛和9头安格斯公牛进行麻醉。在术前-48小时、术后、解救镇痛后和24小时录制3分钟的视频。两名评估人员对95个随机视频进行了两次评估,间隔一个月。
不同品种之间的疼痛评分没有显著差异。所有量表的评分者内和评分者间信度从良好(>0.70)到非常好(>0.81)不等。效标效度显示,数字评定量表和视觉模拟量表与UCAPS和CPS之间以及UCAPS和CPS之间存在强相关性(0.76-0.78)。UCAPS和CPS具有反应性;术后所有项目和总分均增加。两个量表都具有特异性(81-85%)和敏感性(82-87%)。解救镇痛的分界点UCAPS为>4,CPS为>3。
UCAPS和CPS在评估安格斯公牛和内洛尔公牛术后疼痛方面是有效且可靠的。
