Carpal Tunnel, Dexamethasone, Dexmedetomidine, Ozone
Conditions
Brief summary
The aim of the present study is to compare the analgesic efficacy of Dexmedetomidine, Ozone and Dexamethasone regional injection in carpal tunnel syndrome.
Detailed description
Carpal tunnel syndrome (CTS) is a collection of symptoms and signs associated with median neuropathy at the carpal tunnel. Most CTS is related to idiopathic compression of the median nerve as it travels through the wrist at the carpal tunnel. Corticosteroid injection is an extensively used and accepted treatment in mild to moderate CTS according to the guidelines of the American Academy of Orthopedic Surgeons as corticosteroids reduce the inflammation and edema associated with CTS. However, there is no guideline as to which corticosteroid has to be used as the standard treatment in CTS. Triamcinolone acetonide, a commonly used steroid for this indication, is a particulate steroid, which can cause permanent nerve injury if accidentally injected into the nerve. Local ozone injection as a therapeutic option in some musculoskeletal conditions; ozone (O3) gas is a molecule consisting of three oxygen atoms in a dynamically unstable structure. Ozone therapy has been utilized and studied for more than a century.
Interventions
DRUGDexamethasone
Patients will receive a single local injection of 5 mL (3 mL lidocaine (1%) and 2 mL \[8 mg\] dexamethasone) via the same technique.
DRUGDexmedetomidine
Patients will receive injection of 1 microgram/kg dexmedetomidine average (70-100-microgram) (0.7-1ml) plus 4ml lidocaine injection nearby median nerve.
DRUGOzone
Participants will receive a single local injection of 4 ml ozone (10 micrograms/ml) plus to 1 ml lidocaine (1%) using a 25 G needle.

Exclusion criteria
* Patient refusal. * Patients with severe symptoms and signs of CTS as identified per the American Association of Neuromuscular and Electro diagnostic Medicine (AANEM) guidelines,\[14\] as this is an indication for surgery, * Patients who show improvement on medical treatment, * Previous surgical or injectional CTS treatment, * Pregnancy ,co existence of brachial plexopathy, or thoracic outlet syndrome, polyneuropathy, radiculopathy and peripheral nerve lesion in upper limb. * Severe cardiovascular disease * Morbid obese patients (body mass index (BMI) of \>35 kg/m2) * Infection at site of injection. * Bleeding diathesis. * History of thyroid deficiency, uncontrolled diabetes mellitus , rheumatoid arthritis and history of glucose-6-phosphate dehydrogenase (G6PD) deficiency * History of Ozone or Dexmedetomidine allergy. * End stage renal and hepatic disease. * History of inflammatory joint , connective tissue disorders, , burns, any local tissue contractures and history of wrist trauma. * Patients who will not consent to completing The visual analogue scale (VAS) for pain or nerve conduction study before and after injection.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The analgesic efficacy and functional status improvement of Dexmedetomidine, Ozone and Dexamethasone regional injection in carpal tunnel syndrome | Each patient will be assessed at the baseline (before injection) , at 1week, 4weeks, 12weeks, and 24weeks intervals after injection date | The analgesic efficacy and functional status improvement of Dexmedetomidine, Ozone and Dexamethasone regional injection in carpal tunnel syndrome via assessment of Visual Analogue Scale (VAS) before and after injection. VAS used as an effective tool to detect intensity of pain will be recorded (0 to10) 0 represents no pain ,10 worst pain, 1-3 mild pain,4-6 moderate pain and 7-10 severe pain. Each patient will be assessed at the baseline (before injection) , at 1week, 4weeks, 12weeks, and 24 weeks intervals after injection. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Median motor nerve conduction study(NCS) evaluation | Each patient will be assessed at the baseline (before injection) , at 1week, 4weeks, 12weeks, and 24weeks intervals after injection date | Each patient will be assessed regarding electrophysiological changes sensory nerve conduction velocity in millimeter/seconds and distal motor latency in milliseconds at the baseline (before injection), at 1week, 4weeks, 12 weeks and 24 weeks intervals after injection. |
| Sensory nerve conduction study(NCS) evaluation | Each patient will be assessed at the baseline (before injection) , at 1week, 4weeks, 12weeks, and 24weeks intervals after injection date | Each patient will be assessed regarding electrophysiological changes sensory nerve conduction velocity in millimeter/seconds and distal motor latency in milliseconds at the baseline (before injection), at 1week, 4weeks, 12weeks, and 24 weeks intervals after injection. |
| Analgesic requirement | First 48 hours post injection . | Analgesic requirement ( dose and frequency of oral acetaminophen intake in first 48 hours) for post injection . |
