Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

  3. Patients diagnosed as (Complex Regional Pain Syndrome ) based on Budapest criteria There should be at least one symptom or sign in three of the four previous categories that can not be explained by other diagnosis.
  4. The average daily pain intensity required on Numerical Rating Scale is 7 or more for at least 3 months despite of standard therapy which includes: (pharmacologic therapy Non-steroidal anti-inflammatory drugs, Antiepileptic drugs(AEDs), antidepressants), as well as physical therapy and psychiatric care.

Exclusion Criteria:

  • Patient refusal
  • Patients with unstable psychological or psychiatric conditions, including: untreated bipolar disorder, post-traumatic stress disorder, major depression, severe personality disorder and psychotic illness
  • Patients have recently undergone major interventional pain procedures, such as nerve blocks or implantable therapies.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Ultrasound guided Stellate ganglion block
The procedure is going to be the anterior paratracheal approach on the cervical sympathetic chain
Drug: Ultrasound guided Stellate ganglion block
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.
Experimental: unilateral cervical epidural
The patient is placed in prone position, with stabilization of the forehead on a padded support
Drug: unilateral cervical epidural
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 the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The percent on satisfactory relief of pain
Time Frame: 6 month post injection

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.
6 month post injection

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
The degree of chronic pain using Brief Pain Inventory
Time Frame: 6 month post injection

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
6 month post injection
The incidence of complication
Time Frame: 2 hours post-intervention
complications as hypotension, headache and neck pain
2 hours post-intervention
