This study assesses the efficacy of the quadratus lumborum block (QLB) in the management of procedural and periprocedural pain associated with small renal mass cryoablation. To the best of our knowledge, this is the first study that examines the use of QLB for pain management during percutaneous cryoablation of renal cell carcinoma (RCC). A single-center retrospective review was conducted for patients who underwent cryoablation for RCC with QLB between October 2020 and October 2021. The primary study endpoint included a total dose of procedural conscious sedation and administered, postprocedural analgesia. Technical success in cryoablation was achieved in every case. No patients required additional analgesic during or after the procedure, and no complications resulted from the use of the QLB. The QLB procedure appears to be an effective locoregional block for the management of procedural and periprocedural pain associated with renal mass cryoablation.
本研究评估腰方肌阻滞（QLB）在处理与小肾肿块冷冻消融相关的术中及围手术期疼痛方面的疗效。据我们所知，这是第一项研究QLB在肾细胞癌（RCC）经皮冷冻消融术中用于疼痛管理的研究。对2020年10月至2021年10月期间接受RCC冷冻消融并采用QLB的患者进行了单中心回顾性研究。主要研究终点包括术中清醒镇静的总剂量和术后给予的镇痛。每例冷冻消融均取得技术成功。术中及术后无患者需要额外镇痛，且使用QLB未导致任何并发症。QLB程序似乎是一种有效的局部区域阻滞，可用于处理与肾肿块冷冻消融相关的术中及围手术期疼痛。
