Abstract
The goal of this study is to evaluate the effect of adding dexmedetomidine as an adjuvant to steroid injection versus steroid alone in chronic low back pain caused by sacroiliac joint arthritis. Sixty patients of both sex, ASA grade 1 and 2, between the ages of 18-70 years, BMI less than 30 kg/m2, after diagnosis of sacroiliac joint dysfunction and failure of conservative management were randomly allocated into two groups (n=30). Group (1): patients received SI injection with 2ml of long-acting corticosteroid (14 mg Betamethasone) and 0.5 ml of normal saline and group (2): patients received SI injection with 2ml of long-acting corticosteroid (14 mg Betamethasone) and 0.5ml dexmedetomidine (50 mcg). Patients were observed for vital signs, pain intensity and possible side effects in the recovery room for 4 hours then discharged. The patient’s pain intensity using Numerical Rating Scale, or functional improvement using Oswestry Disability Index and Functional Rating Scale and complications were followed up at 2 weeks, 4 weeks and 12 weeks. While, short assessment of patient satisfaction was assessed 2 weeks after injection. The results revealed that addition of dexmedetomidine to steroids in sacroiliac joint injection is of low value. There was no statistically significant difference between the steroid group and the dexmedetomidine group regarding the changes in the NRS, ODI and FRI scores at 2 weeks, 4 weeks and 12 weeks after injection.
Highlights
Sacroiliac joint is one of the major axial back pains bellow L5, contributed to SIJ joints connecting the sacral spines and the dysfunction
This study aimed to compare the benefits of back surgery were divided to 2 groups, group dexmedetomidine as an adjuvant to steroid (C) received epidural injection of 20 mL of: injection versus steroid alone in chronic low betamethasone (14 mg) and bupivacaine 0.5 mg back pain through pain score (VAS)
In our study we found that the mean value group) received I.V and intra-articular saline, of NRS, ODI and FRI after injection was (I.A group) received I.V saline and intrasignificantly lower than before injection in both articular dexmedetomidine, and (I.V) group steroid and dexmedetomidine groups
Summary
Sacroiliac joint is one of the major axial back pains bellow L5, contributed to SIJ joints connecting the sacral spines and the dysfunction. This joint has an essential role in specific and diagnostic physical examination maintenance of body stability. 27% of low maneuvers have low diagnostic value [1]. The international association for the study of pain proposed the following criteria for making the because diagnosis of sacroiliac joint pain: exposure, high cost, as they assess the bony. ● Pain present in the region of the SIJ. Components only not the soft tissue and. ● Stressing the joint by clinical tests. Most injection of the contrast causes drug dilution common used tests. Patrick’s are: test, the risks of repeated radiation [4].
