The aim of this study was to investigate the analgesic efficacy of a preoperative acupuncture treatment in 24 client-owned dogs undergoing thoracolumbar hemilaminectomy. Dogs were randomly assigned to either group A (Acupuncture) or group C (Control). Before skin incision, group A was treated with acupuncture, performed under general anaesthesia for 30 min. Rescue intraoperative fentanyl was administered following a 20% increase in cardiovascular parameters compared to baseline values, measured before incision. An observer masked to the treatment assessed pain, pre- and postoperatively, with the Glasgow (GCPS), the Colorado (CPS) pain scales and a Visual Analogue Scale (VAS); additionally, the mechanical thresholds (MT) were measured with the Electronic von Frey Anaesthesiometer (EVF) at four points located near the herniated disc. The groups were compared with respect to intraoperative cardiovascular and respiratory variables, rescue fentanyl administered in total and at different surgical events (first incision [FI], drilling [DR], disc removal [RE] and skin suturing [ST]), and pre- and postoperative pain scores and MT. Group A received less fentanyl than group C (P = 0.014); this difference was significant at FI P = 0.035) and RE (P = 0.004). The improvement in postoperative CPS score (P = 0.013), VAS score (P = 0.003) and MT (P = 0.001) compared to preoperative values was greater for group A than for group C, whereas the treatment assignment had no effect on postoperative changes in GCPS compared to baseline. Pre-operative acupuncture may help improving perioperative analgesia in dogs with intervertebral disc herniation undergoing thoracolumbar hemilaminectomy.
本研究旨在探讨术前针刺治疗对 24 只接受胸腰椎半椎板切除术的患犬的镇痛效果。将犬随机分为 A 组（针刺组）和 C 组（对照组）。在皮肤切开前，A 组在全身麻醉下接受针刺治疗，持续 30 分钟。与基线值相比，心血管参数增加 20%时，即切口前，给予术中芬太尼补救。一名对治疗情况不知情的观察者使用格拉斯哥（GCPS）、科罗拉多（CPS）疼痛量表和视觉模拟量表（VAS）评估术后和术前疼痛；此外，还使用电子 von Frey 麻醉计（EVF）在靠近椎间盘突出的四个部位测量机械阈值（MT）。比较两组术中心血管和呼吸变量、总及不同手术事件（首次切口[FI]、钻孔[DR]、椎间盘切除[RE]和皮肤缝合[ST]）时给予的芬太尼补救量以及术前和术后疼痛评分和 MT。A 组比 C 组接受的芬太尼更少（P = 0.014）；FI 时的差异具有统计学意义（P = 0.035），RE 时的差异也具有统计学意义（P = 0.004）。与术前相比，A 组的术后 CPS 评分（P = 0.013）、VAS 评分（P = 0.003）和 MT（P = 0.001）改善更大，而与基线相比，治疗分配对术后 GCPS 变化没有影响。术前针刺治疗可能有助于改善接受胸腰椎半椎板切除术的椎间盘突出患犬的围手术期镇痛效果。
