Dexmedetomidine versus hyaluronidase along with lumbar transforaminal epidural steroid injection in failed back surgery: a randomized double-blind clinical trial.

Background: Failed back surgery syndrome is a common problem faced by chronic pain management specialists. Steroid-only epidural injections have modest efficacy because of excessive scarring. Epidural hyaluronidase (HA), functions as a depolymerizing agent, successfully breaking down adhesions and collagen bundles, whereas dexmedetomidine (DEX) helps to reduce inflammation.

Transforaminal lumbar epidural injection of dexmedetomidine versus magnesium sulfate combined with dexamethasone for lower limb radicular pain management: a randomized, clinical trial.

Background: Epidural steroid injections are frequently used to treat chronic radicular pain of a discogenic origin; however, their efficacy remains limited. Magnesium sulfate and dexmedetomidine are emerging adjuvants with the potential to enhance the effectiveness and prolong the therapeutic duration of steroid injections.

Methods: In this randomized, double-blind study, 90 patients with unilateral lower limb radiculopathy due to lumbar disc prolapse who did not respond to conservative treatment for 12 weeks were assigned to three groups.
