Study summary

Pain relief and functional impairment have been shown to remain poor to moderate over weeks after emergency department discharge, in patients who seek ED management for acute nontraumatic, nonradicular low back pain.

The investigators made the hypothesis that ultrasound-guided interfascial infiltration of local anesthesics and corticoid is efficient and safe in treating patients presenting to the ED with acute non specific low back pain. The investigators aimed to compare early and short term functional impairment and pain relief one day and 1 week after interfacial infiltration, as compared to standard medical treatment

Read the detailed description

This is a single center observational feasibility study enrolling ED patients presenting with acute unspecific low back pain.

Ultrasound-guided interfascial infiltration is proposed to eligible patients presenting to our ED with low back pain and disability, as part of routine care. Patients receive standard medical treatment if they refuse interfascial infiltration or in case of absence or unavailability of a trained operator.

Patients were followed-up at 1 day and 7-days pots ED discharge by telephone interview conducted by an independent member of our research team not involved in patient's management

Groups and cohorts

  • Interfascial infiltration

    Injection of L-bupivacaine (50 mg) and dexamethasone (4 mg) in the interfascial space under ultrasound guidance.

    Other: Interfascial infiltration

  • Standard medical treatment

    Standard medical treatment include acetaminophen, NSAIDs and muscle relaxant as first line pharmacological treatment and escalation to analgesics level II or morphine if required, as needed for low back pain, in agreement with national guidelines Route of administration (orally or iv) was let at the discretion of the attending emergency physician.

    Other: Standard medical treatment

Interventions

  • OtherInterfascial infiltration

    Injection of L-bupivacaine (50 mg) and dexamethasone (4 mg) in the interfascial space under ultrasound guidance. Patients were kept under surveillance for at least one hour before discharge. Patients were discharged home with a 7 day supply of acetaminophen 1000 mg orally every 6 h, ketoprofen 100 mg, orally twice a day, and muscle relaxant as needed. Patients were instructed to take tramadol 50 mg, orally every 6h as needed for low back pain, in case of insufficient relief.
