Main objective

Scope: Efficacy

Evaluate the effectiveness of the erector spinae plane block (ESPB) in managing patients with non-specific low back (NSLB) pain, by reducing pain and allowing immediate mobility.

Secondary objectives 6

  1. Evaluate the effectiveness of the ESPB to promote the patient's experience (PREMs) by reducing pain and improving quality of life.
  2. Evaluate the effectiveness of the ESPB to improve functional rehabilitation (PROMs) by promoting early walk's resumption and physical activity.
  3. Evaluate the effectiveness of the ESPB to reduce the recurrence of low back pain episodes.
  4. Evaluate the effectiveness of the ESPB to reduce side effects related to rescue medications (such as nausea, vomiting, and chronic opioid consumption).
  5. Evaluate the effectiveness of the ESPB to facilitate earlier return to work.
  6. Evaluate the cost-utility of ESPB compared to standard of care.

#TitleAllocationBlindingRoles blindedArms
1 Randomization procedure
Randomization will be performed using a minimization process and will be stratified by study centers and by the side of the block administration (unilateral or bilateral) with a ratio (1:1) and 150 patients per group, the design will define the treatment administered according to the two groups: ESP BLOCK group versus Control group.
Randomised Controlled Double [{"id":156400,"code":2,"name":"Investigator"},{"id":156401,"code":1,"name":"Subject"}] Experimental arm: ropivacaïne 0.2% (20 ml) and 8 mg dexamethasone (2 ml)
Control arm: isotonic saline solution NaCl 0.9 % (total 22 ml)
