Efficacy Evaluation Of Ultrasound-guided Cervical Nerve Root Block In The Treatment Of Cervical Radiculopathy

Objective: To explore the clinical effectiveness and feasibility of ultrasound-guided cervical nerve root block in the treatment of cervical radiculopathy,and analyze the advantages and disadvantages of different evaluation scales for evaluating the efficacy of ultrasound-guided cervical nerve root block.Methods: A total of 34 patients underwent ultrasound-guided cervical nerve root block in the Department of Ultrasound of Shengjing Hospital Affiliated to China Medical University from September 2018 to December 2020.All patients were investigated for their preoperative basic information,and VAS,NDI and SF-12 were investigated before surgery.VAS was conducted 10 minutes after surgery.VAS,NDI,SF-12 and Odom efficacy evaluation criteria were conducted 3 days,2 weeks,4 weeks and 3 months after surgery.SPSS 23.0 software was used to evaluate the efficacy of ultrasound-guided cervical nerve root block in the treatment of cervical radiculopathy by paired sample t test and paired X~2 test.Cronbach’s α coefficient was used to test the reliability of the NDI and SF-12;KMO test and Bartlett’s spherical test were used to test the validity of NDI and SF-12.Results: All 34 patients included in the study had no adverse reactions.At 10 minutes,3days,2 weeks,4 weeks and 3 months after treatment,the VAS scores of the patients were significantly lower than those before treatment,and the difference was statistically significant(P<0.01).At 3 days,2 weeks,4 weeks and 3 months after treatment,the NDI scores of the patients were significantly lower than those before treatment,and the difference was statistically significant(P<0.01).At 3 days,2 weeks,4 weeks and 3months after treatment,the PCS and MCS scores of the patients in the SF-12 scale were significantly higher than those before treatment,and the difference was statistically significant(P<0.01).At 2 weeks after treatment,the excellent and good rates in the Odom efficacy evaluation criteria of patients were significantly higher than those at 3days after treatment,and the difference was statistically significant(P<0.05);at 4 weeks and 3 months after treatment,the excellent and good rates in the Odom efficacy evaluation criteria of patients were significantly higher than those at 3 days after treatment,and the difference was statistically significant(P<0.01).Cronbach’s αcoefficient of NDI was 0.926,which indicated that the reliability of NDI was excellent.Cronbach’s α coefficient of SF-12 was 0.720,which indicated that the reliability of SF-12 was good.The KMO value of NDI was 0.885,which indicated that the validity of NDI was excellent.The KMO value of SF-12 was 0.883,which indicated that the validity of SF-12 was excellent.Conclusions: Ultrasound-guided cervical nerve root block is clinically feasible and effective in the treatment of cervical radiculopathy.NDI scale is more comprehensive than other scales,and has higher reliability and validity.
