A 17-year-old mare undergoing dental surgery suffered a cardiac arrest while being transferred from the surgical theatre to the recovery box. This complication was diagnosed early, thus allowing a prompt start to the cardiopulmonary resuscitation maneuvers. External thoracic compressions, intermittent positive pressure ventilation, and adrenaline administration were at the core of this successful resuscitation. Although it was not possible to confirm the cause of cardiac arrest in this horse, a Bezold-Jarisch reflex due to potential decrease on venous return because of postural change and drug interactions was hypothesized. Based on this report, it appears advisable to smoothly change the position of anaesthetized patient; furthermore, the administration of drugs affecting cardiovascular hemodynamics or sympatho-vagal balance to animals while changing their recumbency should be avoided.
一匹17岁的母马在接受牙科手术时，从手术室转移到恢复箱的过程中发生了心脏骤停。这种并发症被早期诊断出来，从而能够迅速开始心肺复苏操作。胸外按压、间歇性正压通气和肾上腺素给药是这次成功复苏的核心。虽然无法确定这匹马心脏骤停的原因，但推测可能是由于姿势改变和药物相互作用导致静脉回流减少而引发了贝佐尔德-雅里什反射。基于本报告，似乎建议平稳改变麻醉患者的体位；此外，应避免在改变动物卧位时给予影响心血管血流动力学或交感-迷走神经平衡的药物。
