About this study

Official title: Comparison Between Cervical Epidural and Stellate Ganglion Block in Management of Complex Regional Pain Syndrome of the Upper Limb A Prospective Comparative Study

Evaluate the efficacy of two regimens of management in relieving chronic refractory pain in patients with upper limb complex regional pain syndrome after orthopedic trauma

Read the detailed description

Ideal therapy for Complex Regional Pain Syndrome is multimodal with the use of physical therapy, psychotherapy, and pharmacologic therapy to complement interventional procedures. Within pharmacotherapy, drugs most often utilized include non steroidal anti-inflammatory drugs (NSAIDs), gamma-aminobutyric acid receptor agonists (i.e., gabapentin, pregabalin), and N-methyl-D-aspartate (NMDA) receptor antagonists (i.e., Ketamine).

In complex Regional Pain Syndrome treatment, stellate ganglion block (SGB) is a well-established method of nerve blockade of the sympathetic ganglia in the lower cervical and upper thoracic region.

Epidural block have differential block as sensory, motor, and sympathetic. Nerve functions are blunt at different rates and to different degrees. Sensory block occurs with a lower concentration of Local anathesia and develops faster than motor block with coexisting sympathectomy.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Ultrasound guided Stellate ganglion blockDrug

    Under visualization with ultrasound, a 22-gauge, 5-cm needle inserted perpendicular to the skin to rest anteriorly to the precervical fascia. 6 mL lidocaine 0.125% and 8 mg dexamethasone in a total volume of 8 mL is used. After injection of a 0.5-mL test dose to exclude intravascular positioning, the remainder of the appropriate dose was administered. The patient will be encouraged to lie flat for 3 minutes after the injection and then to sit up.

  • unilateral cervical epiduralDrug

    Aseptic betadine skin preparation will be performed and sterile drapes will be applied. Local anesthetic infiltration of the skin at C7-T1 interspace will be done using 2-3 mL of lidocaine 2% with guidance of the C-arm an 18-gauge. Tuohy needle will be inserted at C7-T1 interspace and directed towards either right or left epidural recess according to the site of the operation. Identification of entering the epidural space will be confirmed by hanging drop technique. The position of the needle is the confirmed by injection of 1 mL of non-ionized diluted dye (omnipause 300) to confirm unilateral spread of the dye. After that, a test dose was administrated, consisting of 2 mL of 2% lidocaine with 1:200,000 epinephrine.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The percent on satisfactory relief of pain

    Numerical rating scales (NRS) is an 11-Point Scale for patient self-reporting of pain. It is based solely on the ability to perform activities of daily living (ADLs) with 0 being "no pain" and 10 being "the worst pain imaginable.

    NRS was measured before, immediately after injection, 3 and 6 month post injection.

    Measured: 6 month post injection

Secondary outcomes (2)
  1. The degree of chronic pain using Brief Pain Inventory

    Brief Pain Inventory short form (BPI-SF) questionnaire. It is a nine item self-administered questionnaire used to evaluate the severity of a patient's pain and the impact of this pain on the patient's daily functioning. The patient is asked to rate their worst, least, average, and current pain intensity, list current treatments and their perceived effectiveness, and rate the degree that pain interferes with general activity, mood, normal work, relations with other persons, sleep, and enjoyment of life on a 10 Point Scale

    BPI-SF was measured before, immediately after injection, 3 and 6 month post injection

    Measured: 6 month post injection

  2. The incidence of complication

    complications as hypotension, headache and neck pain

    Measured: 2 hours post-intervention

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Ultrasound guided Stellate ganglion block and unilateral cervical epidural in people with Stellate Ganglion Block and Cervical Epidural, run by Tanta University at 1 site in Egypt.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 5 Sep 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The percent on satisfactory relief of pain (time frame: 6 month post injection). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Sep 2023.
