Ultrasound-guided Transgluteal Sciatic Nerve Hydrodissection for the Treatment of Sciatica in the Emergency Department

8 de mayo de 2026 actualizado por: Kaiser Permanente

Ultrasound Guided Transgluteal Sciatic Nerve Hydrodissection for the Treatment of Sciatica in the Emergency Department

The goal of this observational study is to see whether it would be feasible to treat patients who come to the emergency department with pain related to sciatica using an ultrasound guided injection of dextrose in water solution ("sugar water") into the tissue that surrounds the sciatic nerve in the gluteal region. THe study will looks at a few things:

  • Is the treatment feasible within the setting of the emergency department
  • Is the treatment safe in the short term (up to 72 hours after the injection)
  • Is the treatment good for lowering patients' pain from sciatica in the short term (immediate and up to 72 hours' follow up)
  • How does the treatment compare to current standard medicines given to patients for sciatica in the emergency department in terms of lowering pain

Patients who came to the emergency department and had the injection as part of their care for sciatica will answer some questions about their symptoms during a phone call follow up 72 hours after leaving the emergency department.

Armas e Intervenciones

Grupo de participantes/brazo
Intervención / Tratamiento
Sin intervención: Comparison group
These are patients who received current usual or standard treatment for their sciatic pain, such as oral pills and/or intravenous or intramuscular injections with various medications in the emergency department. These patients are followed contemporaneously as a comparison to the patients who received the hydrodissection injection.
Otro: transgluteal sciatic nerve hydrodissection
These patients received the transgluteal sciatic nerve hydrodissection injection procedure when a study investigator was present to administer it.
Injection of dextrose in water solution (D5W) under ultrasound guidance into the tissue plane that encloses the sciatic nerve between its two neighboring muscles.

¿Qué mide el estudio?

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Rate of Successful Transgluteal Sciatic Nerve Hydrodissection (TSNH) Procedure Completion Among Eligible Emergency Department Patients
Periodo de tiempo: From enrollment to 72-hour follow-up completion
Procedural feasibility will be assessed using four metrics: (1) Enrollment rate, measured as proportion of screened patients meeting eligibility criteria who were enrolled; (2) Procedural attempt rate, measured as proportion of enrolled patients in whom TSNH was attempted; (3) Procedural completion rate, measured as proportion of attempted procedures in which successful injection of D5W was achieved on ultrasound visualization; (4) Follow-up completion rate, measured as proportion of enrolled patients completing the 72-hour structured telephone follow-up.
From enrollment to 72-hour follow-up completion
Incidence of Procedure-Related Adverse Events Within 72 Hours Following Transgluteal Sciatic Nerve Hydrodissection (TSNH)
Periodo de tiempo: From time of injection to 72-hour post-discharge telephone follow-up
Incidence of adverse events assessed via structured 72-hour telephone follow-up using a standardized script administered to all patients participants by study the investigators. Adverse events evaluated include: (1) new or worsening motor weakness in the ipsilateral lower extremity; (2) new sensory disturbance in the ipsilateral lower extremity; (3) injection-site pain beyond expected post-procedural soreness; (4) signs or symptoms of injection-site infection. Results reported as number and percentage of participants experiencing each adverse event type.
From time of injection to 72-hour post-discharge telephone follow-up

Medidas de resultado secundarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Change in Numeric Rating Scale (NRS) Pain Score From Baseline to Post-Treatment and 72-Hour Follow-Up
Periodo de tiempo: From enrollment to 72-hour post-discharge follow-up
Change in self-reported pain level measured using the Numeric Rating Scale (NRS), an 11-point scale ranging from 0 to 10, where 0 = no pain and 10 = worst possible pain (higher scores indicate worse outcome). Scores recorded at three timepoints: (1) baseline, prior to any treatment in the ED; (2) post-treatment, approximately 15 minutes after TSNH procedure completion for the TSNH group, and at a comparable timepoint for the comparison group; (3) 72-hour follow-up, via structured telephone contact after ED discharge. Change from baseline pain level calculated at each timepoint. Pain scores compared between participants receiving TSNH and a contemporaneous comparison group receiving standard pharmacologic care.
From enrollment to 72-hour post-discharge follow-up
