Clinical Study Of Short-course Spinal Cord Electrical Stimulation For The Treatment Of Severe Chronic Pain Diseases

Objective(s):This study used spinal cord electrical stimulation(Spinal Cord Stimulation,SCS)in patients with severe chronic pain,To explore the clinical efficacy and safety of short-course spinal electrical stimulation(temporary Spinal Cord Stimulation,t SCS)in patients with severe chronic pain.Methods: A total of 30 patients undergoing SCS from June 2021 to November2022 were studied,All the patients were diagnosed with severe chronic pain,and the pain visual analog score is greater than or equal to 6 points,conservative treatment such as oral drugs and nerve block treatment effect is poor,all the patients underwent percutaneous SCS implantation under G arm positioning and guidance in the operating room of the anesthesiology department of our hospital.After postoperative follow-up observation for 3 months,the VAS scores,Pittsburgh Sleep Quality Index(Pittsburgh Sleep Quality Index,PSQI),complications,adverse reactions,postoperative pain recurrence and patient satisfaction after 1 day,1 week,January and March after treatment were recorded.The collected data were statistically analyzed by the SPSS26 statistical software.Results: 1.30 patients were followed by time and not lost to follow-up,and the sample group data of VAS score showed nonnormal distribution by SW test.The VAS score was 7.0(6.3,7.0),4.0(4.0,4.0)at 1 day after treatment,4.0(4.0,4.0)at 1 week after treatment,2.00(2.0(2.0,2.0).By rank sum test analysis,VAS scores decreased in all groups after treatment,with the most significant decrease in VAS scores at 1 day after treatment,VAS score before and after SCS treatment was statistically significant(P <0.05).Statistical analysis of multiple comparisons between the groups after treatment:significant differences were found between the VAS scores at 1 week,January,and March(P <0.05),there were significant differences between VAS scores at1 week after treatment and statistically significant differences(P <0.05),there was a difference in VAS scores between January and March after treatment,but no significant difference(P> 0.05).2.The PSQI sample group data were normally distributed by the S-W test,with PSQI(14.67 ± 2.24)prior to treatment,1 day after treatment(11.60 ±1.33),1 week after treatment,(9.47 ± 1.20),1 month after treatment(8.37 ±1.27),3 months after treatment(8.33 ± 1.24)after treatment.PSQI scores decreased in all groups after treatment,with the most significant decrease in PSQI at 1 day after treatment,after analysis of variance,there was a significant statistical difference in PSQI scores before and after SCS treatment(P <0.05).Multiple comparative analysis was performed between the groups after treatment,significant differences were found between PSQI 1 day after treatment and 1 week,January,and March,respectively,the difference was statistically significant(P <0.05).There were differences between PSQI at 1week after treatment and those in January and March,respectively,statistically significant difference(P <0.05).The difference in PSQI after treatment was not statistically significant(P> 0.05).3.During the follow-up period,there were 0 patients with repeated or aggravated pain,and 25 patients had abnormal sensation in the original pain area,mostly with numbness(about 83.3%),among which 3 cases had obvious numbness in the lesion site(about 10%).The abnormal sensation basically disappeared after pulling out the spinal electrical stimulation electrode,and there was no abnormal sensation in the pain area during March follow-up.The overall incidence of adverse effects during treatment was 16.7%.4.In the follow-up survey,16 patients were very satisfied,accounting for53.33%;12 were satisfied,accounting for 40%;0 generally satisfied patients and 2 were dissatisfied,accounting for 6.33% of the total.Conclusion(s): The application of t SCS to treat severe chronic pain can significantly reduce the pain of patients with poor drug treatment,achieve the purpose of rapid pain relief,and improve the sleep quality of patients,Is an effective way to treat severe chronic pain.The treatment process of this study is guided by the G arm,it has high accuracy and safety,low incidence of adverse reactions,and accurate efficacy in short-term follow-up observation.Therefore,it can be used as a new concept for the treatment of chronic pain,and is worth promotion and application in clinical practice.
