Evaluation of anesthesia effect of ropivacaine nerve block under general anesthesia combined with B-ultrasound guidance in patients undergoing lower limb fracture surgery
全身麻醉结合B超引导下的罗哌卡因神经阻滞在下肢骨折手术患者中的麻醉效果评估

摘要

目的 调查全身麻醉结合B超引导下的罗哌卡因神经阻滞在下肢骨折手术患者中的麻醉效果。方法研究选择对照形式，将在本院治疗的56例患者作为本次研究的对象，所有对象均源自2024年5月-2025年5月期间登记的下肢骨折手术患者，按照随机数字表法的分组形式，将56例患者划分为不同麻醉方式的两个小组。对照组的28例患者仅采用全身麻醉，观察组的28例患者采用全身麻醉结合B超引导下罗哌卡因神经阻滞，以此比较两组患者术后的疼痛感、时间指标、不良反应发生率和满意评分。结果 观察组患者采用全身麻醉结合B超引导下罗哌卡因神经阻滞能够有效缩短各项时间指标（P＜0.05）；观察组患者在术后各时间段的疼痛感消退更快（P＜0.05）；全身麻醉结合B超引导下罗哌卡因神经阻滞能够有效降低不良反应发生率（P＜0.05）；观察组患者对全身麻醉结合B超引导下罗哌卡因神经阻滞更具满意度（P＜0.05）。结论 全身麻醉结合B超引导下的罗哌卡因神经阻滞在下肢骨折手术患者中的麻醉效果十分显著，能够有效缩短患者的苏醒时间、拔管时间、定向力恢复时间，降低不良反应发生率和术后各个时间段的疼痛感，且患者对该手术方式更满意，值得临床推广使用。

Abstract

Objective To investigate the anesthetic effect of ropivacaine nerve block under general anesthesia combined with B-ultrasound guidance in patients undergoing lower limb fracture surgery.
Methods The study selected a control form and selected 56 patients treated in our hospital as the subjects of this study. All subjects were from lower limb fracture surgery patients registered between May 2024 and May 2025. According to the random number table method, the 56 patients were divided into two groups with different anesthesia methods. The control group of 28 patients only received general anesthesia, while the observation group of 28 patients received general anesthesia combined with B-ultrasound guided ropivacaine nerve block. The postoperative pain, time indicators, incidence of adverse reactions, and satisfaction scores of the two groups of patients were compared.
Results In the observation group, the use of general anesthesia combined with B-ultrasound guided ropivacaine nerve block can effectively shorten various time indicators (P<0.05); The pain relief of the observation group patients was faster at various time points after surgery (P<0.05); General anesthesia combined with B-ultrasound guided ropivacaine nerve block can effectively reduce the incidence of adverse reactions (P<0.05); Patients in the observation group were more satisfied with the combination of general anesthesia and B-ultrasound guided ropivacaine nerve block (P<0.05).
Conclusion   The combination of general anesthesia and B-ultrasound guided ropivacaine nerve block has a significant anesthetic effect in patients undergoing lower limb fracture surgery. It can effectively shorten the patient's recovery time, extubation time, and directional force recovery time, reduce the incidence of adverse reactions and postoperative pain at various time periods. Moreover, patients are more satisfied with this surgical method, which is worthy of clinical promotion and use.
