Dexmedetomidine Versus Triamcinolone Treatment of Carpal Tunnel Syndrome

Study Overview
=================
Brief Summary
-----------------
Carpal tunnel syndrome (CTS) is a common mononeuropathy due to entrapment of the median nerve in the carpal tunnel. a lot of modaleties are available for treatment of mild to moderate CTS.

Detailed Description
-----------------
Carpal tunnel syndrome (CTS) is a common mononeuropathy due to entrapment of the median nerve in the carpal tunnel. a lot of modaleties are available for treatment of mild to moderate CTS. In case of failed conservative oral therapey, local hydro-dessction of the median nerve can be done with saline alone. local anethetics, steroids, hyalase,and ozone have been utilized to augment the symptoms reliefe. Dexmeditomidine (DEX) has been studied as adjuvant for nerve block to aumnet the pain reliefe. Recently, it has been discovered that DEX can offer some antinflammatory effects when injected in the perineural area. Upon such discovery, the goal of this study has been built.

Design Details

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: Parallel Assignment Investigate if, and to what extent,carapl tunnel hydro-dissection using DEX or triamcinolone (TM) along with saline, under ultrasound guidance, can improve the clinical condition, change in nerve conduction parameters of patients with CTS and delay or avoid the surgical intervention.
Masking: Double
