超声与DSA引导下颈椎脊神经根阻滞的临床疗效对照研究

A COMPARATIVE STUDY OF CLINICAL EFFICACY OF CERVICAL

摘要:

摘要：目的：比较超声与DSA引导下颈神经根阻滞的临床效果和准确性。 方法：40例诊断为C5-7单神经根病变的患者，随机分为2组：超声引导下神经 根阻滞组（U组，n=20）；DSA引导下神经根阻滞组（D组，n=20）。分别记 录操作耗时；对比阻滞成功后前后位X片图像以及推注对比剂后神经根、显影 图像；治疗后不良反应；治疗前、治疗后即刻4小时、24小时、1周、1月NRS 评分；治疗后总体有效率。结果：两组患者无头晕、呼吸抑制等不良反应。U组 操作时间为5.0±1.0分钟；D组操作时间为10.0±0.8分钟，差异有统计学意 义(P＜0.05)。治疗前、治疗后各时间点NRS评分：U组分别为6.5±1.2，2.0± 0.2，2.2±0.3，2.5±0.3，3.5±0.5，3.8±0.6；D组分别为6.8±1.5，2.0 ±0.3，2.1±0.2，2.4±0.4，2.8±0.8，3.0±0.4。组内比较治疗前后差异有 统计学意义(P＜0.05)；治疗后1月，组间比较差异有统计学意义(P＜0.05)。随着 时间推移，镇痛效能略有减低。总体有效率基本相似。结论：超声引导下颈神经 根阻滞治疗安全性高，耗时短，准确性高，短期疗效确切。长期疗效需进一步观 察。

Abstract:Objective:To compare the clinical effect and accuracy of cervical nerve root block guided by ultrasound and DSA. Methods:40 patients diagnosed with C5-7 single radiculopathy were randomly divided into two groups:ultrasound-guided nerve root block group ( group U, n=20);DSA-guided nerve root block group (group D, n=20). Respectively,Recording operation time;Anteroposterior X-ray images were compared after successful block and nerve roots were developed after contrast agent injection images;Adverse reactions after treatment;NRS at 4 hours, 24 hours, 1 week, and 1month after treatment Score;Overall response rate after treatment. Results: There were no adverse reactions such as dizziness and respiratory depression in the two groups. The operation time is 5.0±1.0 min in group U;The operation time of group D was 10.0±0.8 minutes, and the difference was statistically significant (P < 0.05).NRS scores before and after treatment were 6.5±1.2 and 2.0±0.2 2.2±0.3, 2.5±0.3, 3.5±0.5, 3.8±0.6 in the group U ,respectively，Group D was 6.8±1.5, 2.0±0.3, 2.1±0.2, 2.4±0.4, 2.8±0.8, 3.0±0.4.There were differences before and after treatment within the group，the difference was statistical significance (P < 0.05).There was significant difference between groups 1month after treatment(P < 0.05)，As time went on, Pain efficacy is slightly reduced.The overall efficiency is similar. Conclusion:Ultrasound-guided cervical nerve root block is an effective treatment high security, short time, high accuracy, short-term efficacy is definite.The long-term effect needs to be further observed.
