BACKGROUND: Kyphoplasty for osteoporotic vertebral compression fractures (OVCF) is a short but painful intervention. Different anesthetic techniques have been proposed to control pain during kyphoplasty; however, all have limitations. OBJECTIVE: To compare the effectiveness and safety of ultrasound-guided thoracic paravertebral block with local anesthesia for percutaneous kyphoplasty (PKP). METHODS: In this prospective study, non-randomized patients with OVCF undergoing PKP received either ultrasound-guided thoracic paravertebral block (group P) or local anesthesia (group L). Perioperative pain, satisfaction with anesthesia, and complications were compared between the groups. RESULTS: Mean intraoperative (T1–T4) perioperative visual analog scale (VAS) scores were significantly lower in group P than in group L (2 [1–3] vs. 3 [2–4], 2 [2–3] vs. 4 [2–4], 2 [2–3] vs. 5 [3–5], and 3 [2–3] vs. 5 [3–5], respectively; P< 0.05). Investigators’ satisfaction scores, patients’ anesthesia satisfaction scores, and anesthesia re-administration intention rate were significantly higher in group P than in group L (4 [3–5] vs. 3 [2–4], 2 [2–3] vs. 2 [1–3], 90.63% vs. 69.70%; P< 0.05). There was no significant intergroup difference in complications. CONCLUSIONS: Ultrasound-guided thoracic paravertebral block has similar safety to and better effectiveness than local anesthesia in PKP.

超声引导胸椎旁阻滞与局部麻醉对骨质疏松性压缩性骨折患者经皮后凸成形术的有效性和安全性

背景：骨质疏松性椎体压缩性骨折 (OVCF) 的椎体后凸成形术是一种时间短但疼痛的干预措施。已经提出了不同的麻醉技术来控制椎体后凸成形术中的疼痛；然而，它们都有局限性。目的：比较超声引导胸椎旁阻滞与局部麻醉用于经皮椎体后凸成形术（PKP）的有效性和安全性。方法：在这项前瞻性研究中，接受 PKP 的非随机 OVCF 患者接受了超声引导的胸椎旁阻滞（P 组）或局部麻醉（L 组）。比较两组的围手术期疼痛、麻醉满意度和并发症。结果：P 组的平均术中 (T1–T4) 围手术期视觉模拟量表 (VAS) 评分显着低于 L 组（2 [1–3] 对 3 [2–4]、2 [2–3] 对. 4 [2–4]、2 [2–3] 对 5 [3–5] 和 3 [2–3] 对 5 [3–5]；P < 0.05）。P组研究者满意度评分、患者麻醉满意度评分、麻醉再给药意向率均显着高于L组（4[3-5] vs. 3[2-4]、2[2-3]对比 2 [1–3]，90.63% 对比 69.70%；P< 0.05）。并发症没有显着的组间差异。结论：在 PKP 中，超声引导的胸椎旁阻滞与局部麻醉具有相似的安全性和更好的有效性。P < 0.05）。并发症没有显着的组间差异。结论：在 PKP 中，超声引导的胸椎旁阻滞与局部麻醉具有相似的安全性和更好的有效性。P < 0.05）。并发症没有显着的组间差异。结论：在 PKP 中，超声引导的胸椎旁阻滞与局部麻醉具有相似的安全性和更好的有效性。
