Clinical effect of brachial plexus block anesthesia guided by B-ultrasound
B超引导下臂丛神经阻滞麻醉的临床效果

摘要

目的 本文主要探析B超引导下臂丛神经阻滞麻醉的临床效果。方法 在2020年11月—2021年9月期间，选用于本院骨科接受治疗的80例患者为本次实验的研究主体， 采用奇偶数随机分配的方式分为参照组（n=40）和研究组（n=40）两个组别。两组分别采用不同的治疗方式实施干预，参照组实行常规引导操作，研究组实行B超引导操作，对比两组患者的麻醉起效时间、持续时间，镇痛效果、并发症发生率、平均动脉压及心率。结果 两组患者经过干预后，研究组患者的麻醉起效时间为（4.18±1.05）分，比参照组较短，麻醉持续时间为（528.15±22.05）分，比参照组时间长，且麻醉效果较好其占比为（89.5%），高于参照组（72.1%），并发症发生率为（5%）低于参照组（12.5%），并且平均动脉压及心率均低于参照组。结论 通过对患者实行B超引导下臂丛神经阻滞麻醉，其临床麻醉效果较为理想，通过超声的方式可清楚的找到臂丛神经位置，便于麻醉的操作，且使麻醉的起效时间缩短，并且延长了麻醉药镇痛的时长，对手术的进程起到了重要的辅助作用，同时能够使患者的平均动脉压及心率保持稳定的指标，减少患者并发症的发生，使手术能够顺利完成，缩短了手术时间，提高了临床麻醉的质量与效率，值得推广。

Abstract

Objective investigate the clinical effect of the bracial plexus of the block of anesthesia conducted by B-ultrasound.
Methods from November 2020 to March 2022, 80 patients treated at the hospital's orthopedic ministry were selected as an research subject for this experiment. They were randomly divided into two groups: reference group (n = 40) and research group (n = 40). Two groups were intervened with different treatment methods. The reference group is conducted by standard surgery, and the study group is conducted by B-ultrasound. The onset and duration of anesthesia, analgesic effects, complication incidence, median arterial pressure and heart rate are compared between two groups.
Results After intervention, the start of an anesthesia in the study group is (4.18 ± 1.05), the duration of anesthesia is (528.15 ± 22.05), an effective rate of anesthesia is (89.5%), greater than that in the reference group (72.1%), the incidence of complications is (2.15%) lower than that in the reference group (12.1%). The arterial pressure and heart rate were less than those in the reference group.
Conclusion   The clinical anesthetic effect of the Brazilian plexus block of anesthesia led by B-ultrasound is ideal. The position of anesthesia can be clearly found by ultrasound, suitable for anaesthetic surgery, decreased the start of anesthesia, continued anesthesia, played an important role in the operation process and can maintain the index of arterial pressure and heart rate, reduced complications is worth promoting.
