摘要

麻醉期间体温过低是兽医工作中的一个重要问题,因为它会导致各种并发症,因此了解接受外科手术的动物体温调节因素至关重要。这项回顾性研究旨在评估接受选择性绝育和阉割手术的狗在麻醉过程中的体温变化,并确定性别、预用药剂量、体重、年龄和麻醉持续时间对体温随时间变化的影响。阿德莱德大学(University of Adelaide)的兽医专业学生对110只狗(n=110)进行了选择性卵巢切除术(n=75)和睾丸切除术(n=35),这些狗都参加了这项回顾性研究。研究人员评估了狗在麻醉过程中的体温变化记录,并将体温变化与性别、两种 ACP 预处理剂量(毫克/千克)、体重(千克)、年龄(月)和麻醉时间(分钟)相关联。分析是在 TPm(预处理时的温度)、T0(诱导)、T15、T30、T60、T90、T120 和 TRec(恢复)分钟时进行的。统计分析使用 GenStat 软件进行,包括重复测量分析和方差分析。当 p < 0.05 时,认为差异显著。数据显示,时间与性别之间存在明显的交互作用,在 T60 时,雌性狗比雄性狗感受到更大程度的冷却(p

The effects of general anaesthesia on body temperature of dogs subjected to ovariohysterectomy or orchiectomy performed by veterinary students in a teaching hospital
Hypothermia during anaesthesia is a significant concern in veterinary practice, as it can lead to various complications, making it essential to understand the factors that contribute to temperature regulation in animals undergoing surgical procedures. This retrospective study aimed to evaluate the change in body temperature over the course of anaesthesia in dogs undergoing elective ovariohysterectomy and orchiectomy, and determine the effect of gender, dose of premedication, weight, age and duration of anaesthesia of the change of body temperature over time. One-hundred and ten dogs (n=110) that underwent elective ovariohysterectomy (n=75) and orchiectomy (n=35) surgery performed by veterinary students at the University of Adelaide were enrolled in this study. Dogs’ anaesthesia records were evaluated for change in body temperature over the course of anaesthesia, and correlated with gender, two premedication doses of acepromazine (mg/kg), body weight (kg), age (months) and anaesthesia times (minutes). The analyses were performed at TPm (temperature at premedication), T0 (induction), T15, T30, T60, T90, T120 and TRec (recovery) minutes. Statistical analysis was performed using the GenStat software and included repeated measures analysis and ANOVA. Significance was considered when p < 0.05. The data showed a significant time-by-gender interaction with female dogs experienced a greater degree of heat loss than male dogs at T60 (p<0.01), T90 (p<0.01) and T120 (p<0.01). At recovery, female average temperature was higher than in males (p<0.01). There was no significant difference in body temperature when other covariates were used in the analysis. The core body temperature of female dogs decreased significantly over time compared to males, with the most pronounced differenced during the intraoperative period. However, the study’s retrospective nature and limited sample size may influence the generalizability of these findings.
