Outcome Measures
Primary Outcomes (1)
Circulation Improvement
Improvement of circulation and perfusion in the affected limb by FLIR camera in CRPS patients at a 5-minutes time point after the completion of the block.
5 minutes post procedure
Secondary Outcomes (2)
Comparison between FLIR and Standard Measuring
5 minutes post procedure
Numerical Pain Score Correlation
10 days post procedure
Study Arms (1)
FLIR Imaging
All patients recruited for this study will receive FLIR imaging to monitor the success of a lumbar sympathetic block for CRPS
Interventions
The FLIR camera will collect temperature recordings pre-procedure and 5 minutes post-procedure, which will be used to calculate a delta T to assess achievement of a successful sympathetic block.
Eligibility Criteria
This study is designed to be implemented in a single center in an academic pain center that is specialized in musculoskeletal pain. In a pain center with a high experience in clinical and academic fields, it is planned to apply lumbar sympathetic blocks to the patients diagnosed with CRPS. The Budapest Clinical Diagnostic Criteria will be used to diagnose CRPS Type 1 patients.
You may qualify if:
- The patient is between 18 and 85 years old
- Providing CRPS diagnostic criteria by using Budapest Clinical criteria \[16\]
- The patient has had pain and other symptoms for more than 3 months
- Not responding to conventional medical treatments and multidisciplinary approach
- High NRS detection in pain assessment despite appropriate treatment (NRS = and \> 6/10).
- Pain is a limitation in the patient's functional capacity despite appropriate treatment.
You may not qualify if:
- Patients with suspected disc herniation, spinal stenosis, myelopathy, and suspected radiculopathy in detailed examinations and examinations (MRI, CT).
- Systemic or local infection
- Coagulation disorders
- History of allergy to contrast material
- Malignancy
- Pregnancy
- Uncontrollable medical and psychiatric condition
- The patients diagnosed with dysautonomia, sympathetic dysfunction (such as Raynaud disease or Buerger disease), sweating disorders (such as acquired idiopathic generalized anhidrosis), and patients on vasoactive drugs, the mechanism of action is directly on the vascular tone.
