超声可视化引导下神经阻滞的临床应用价值分析

Analysis of clinical value of ultrasound-guided visualization of nerve block

目的 观察超声可视化引导下神经阻滞的临床应用价值。方法 200例手术患者作为研究对象,以随机数字表法分成对照组和观察组,每组100例。对照组行传统神经阻滞,观察组行超声可视化引导下神经阻滞。比较两组患者麻醉指标(麻醉完成时间、神经阻滞起效时间、神经阻滞持续时间、麻醉药剂量)、麻醉效果、围术期不良事件发生情况。结果 观察组麻醉完成时间(4.06±0.93)min、神经阻滞起效时间(5.09±1.27)min、神经阻滞持续时间(379.53±31.10)min短于对照组的(7.57±1.16)、(16.75±2.13)、(279.64±40.11)min,麻醉药剂量(20.58±2.59)ml少于对照组的(30.02±3.61)ml(P<0.05)。观察组麻醉优良率100.00%高于对照组的94.00%,不良事件发生率0低于对照组的6.00%(P<0.05)。结论 超声可视化引导下神经阻滞可显著缩短麻醉完成时间、神经阻滞起效时间,提升麻醉效果,减少围手术期不良事件的发生,效果理想。

Objective To observe the clinical application value of ultrasound-guided visualization of nerve block.Methods 200 surgical patients were selected as the study subjects.They were divided into a control group and an observation group by random number table method,with 100 patients in each group.The control group was treated with traditional nerve block,and the observation group was treated with ultrasoundguided visualization of nerve block.The anesthesia indexes(anesthesia completion time,onset time of nerve block,duration of nerve block,dosage of anesthetic),anesthesia effect,and the occurrence of perioperative adverse events were compared between the two groups.Results In the observation group,the anesthesia completion time was(4.06±0.93)min,the onset time of nerve block was(5.09±1.27)min,and the duration of nerve block was(379.53±31.10)min,which were shorter than(7.57±1.16),(16.75±2.13),and(279.64±40.11)min in the control group;the observation group had lower dosage of anesthetic of(20.58±2.59)ml than(30.02±3.61)ml in the control group(P<0.05).The observation group had higher excellent rate of anesthesia of 100.00%than 94.00%in the control group,and lower incidence of adverse events of 0 than 6.00%in the control group(P<0.05).Conclusion Ultrasound-guided visualization of nerve block can significantly shorten the anesthesia completion time and onset time of nerve block,improve the anesthesia effect,and reduce the occurrence of perioperative adverse events.The effect is ideal.
