分析B超引导下肌间沟臂丛神经阻滞行锁骨骨折切开复位内固定术中的临床疗效

Analysis of the Clinical Effect of Open Reduction and Internal Fixation for Clavicle Fractures Under the Guidance of B-ultrasound in the Intermuscular Sulcus Brachial Plexus Block

目的探析在锁骨骨折切开复位内固定手术治疗中实施B超引导下肌间沟臂丛神经阻滞后的临床效果。方法选取2017年6月—2020年6月该院收治的行锁骨骨折切开复位内固定手术治疗患者100例作为研究对象,将患者进行统一编号后随机分为治疗组和常规组,每组50例。治疗组在锁骨骨折切开复位内固定手术治疗中实施B超引导下肌间沟臂丛神经阻滞,常规组实施传统盲探肌间沟臂丛神经阻滞。分析B超引导下肌间沟臂丛神经阻滞行锁骨骨折切开复位内固定术中的临床疗效。结果治疗组术后并发症发生率为4.00%(2/50),常规组的术后并发症发生率为20.00%(10/50),差异有统计学意义(χ^(2)=6.061,P=0.014);治疗组的操作时间为(5.54±2.14)min,感觉神经麻醉起效时间为(5.50±2.10)min,运动神经麻醉起效时间为(12.51±2.12)min,相比常规组的(10.24±2.21)、(12.35±1.56)、(16.78±2.37)min时间较短,感觉神经麻醉持续时间为(430.24±45.68)min相比常规组的(365.89±47.21)min时间较长,差异有统计学意义(t=10.803、18.515、9.495、6.927,P<0.05)。结论B超引导下肌间沟臂丛神经阻滞行锁骨骨折切开复位内固定术中的临床疗效显著,具有一定的临床推广和应用价值。

Objective To explore the clinical effect of B-ultrasound-guided brachial plexus block in open reduction and internal fixation of clavicle fracture.Methods A total of 100 patients who underwent open reduction and internal fixation of clavicle fractures treated in the hospital from June 2017 to June 2020 were selected as the research objects.After the patients were uniformly numbered,they were randomly divided into treatment group and conventional group,with 50 cases in each group.In the treatment group,B-ultrasound guided intermuscular brachial plexus block was performed during open reduction and internal fixation of clavicle fractures,and the conventional group received traditional blind probing intermuscular brachial plexus block.To analyze the clinical effect of open reduction and internal fixation for clavicle fractures under the guidance of B-ultrasound-guided intermuscular brachial plexus block.Results The postoperative complication rate in the treatment group was 4.00%(2/50),and the postoperative complication rate in the conventional group was 20.00%(10/50),the difference was statistically significant(χ^(2)=6.061,P=0.014).The operation time of the treatment group(5.54±2.14)min,the onset time of sensory nerve anesthesia(5.50±2.10)min,and the onset time of motor nerve anesthesia(12.51±2.12)min were shorter compared with(10.24±2.21)min,(12.35±1.56)min,(16.78±2.37)min in the conventional group,the duration of sensory nerve anesthesia was(430.24±45.68)min,which was longer than the conventional group(365.89±47.21)min,and the difference was statistically significant(t=10.803,18.515,9.495,6.927,P<0.05).Conclusion B-guided intermuscular sulcus brachial plexus block is effective in open reduction and internal fixation of clavicle fracture,which has certain clinical promotion and application value.
