Clinical effect of ropivacaine paravertebral nerve block on analgesia in thoracic surgery
罗哌卡因椎旁神经阻滞对胸科手术镇痛的临床效果的探讨

摘要

目的 本文对罗哌卡因椎旁神经阻滞对胸科手术镇痛的临床效果作进一步探究，为临床提供可供参考的依据。方法 回顾性分析2021年1月-2021年12月期间在本院行胸科手术的患者为研究对象，共计60例，按接收治疗顺序平均分为高浓度组和低浓度组（每组各30例），对比观察采用超声引导下打椎旁神经阻滞，注入罗哌卡因（浓度0.5%）的高浓度组与注入罗哌卡因（0.375%）的低浓度组的临床效果。结果 统计研究表明，两组患者在采取不同浓度的罗哌卡因椎旁神经阻滞方法后，高浓度组与低浓度组的术后安静时与运动时的疼痛(VAS)评分及不良反应发生率比较，数据差异，P＞0.05，无统计学意义。结论 分析表明，罗哌卡因椎旁神经阻滞对胸科手术麻醉及镇痛可提供满意的临床效果，临床应用价值良好，并且低浓度罗哌卡因可以产生与高浓度罗哌卡因相似的胸科手术镇痛效果。值得在临床椎旁神经阻滞胸科手术镇痛中推广应用。

Abstract

Objective: To further explore the clinical effect of ropivacaine paravertebral nerve block on analgesia in thoracic surgery, and to provide a reference basis for clinical practice.
Methods: a total of 60 patients who underwent thoracic surgery in our hospital from January 2021 to December 2021 were retrospectively analyzed. They were divided into high concentration group and low concentration group (30 cases in each group) according to the treatment order. The clinical effects of paravertebral nerve block guided ultrasonic puncture , high concentration group injected with ropivacaine (0.5%) and low concentration group injected with ropivacaine (0.375%) were compared.
Results: the statistical study showed that after the two groups were treated with different concentrations of ropivacaine for paravertebral nerve block, there was no statistical significance between the high concentration group and the low concentration group in terms of the postoperative pain (VAS) score and the incidence of adverse reactions at rest and during exercise (P > 0.05).
Conclusion  : the analysis shows that ropivacaine paravertebral nerve block can provide satisfactory clinical effect for anesthesia and analgesia in thoracic surgery, and the clinical application value is good. Low concentration ropivacaine can produce similar analgesic effect to high concentration ropivacaine in thoracic surgery. It is worth popularizing the application of paravertebral nerve block in thoracic surgery.
