EFFECT OF DEXAMETHASONE AS A LOCAL ANESTHETIC ADJUVANT IN ULTRASOUND GUIDED BRACHIAL PLEXUS BLOCK
Karim Ahmed Ramadan Bassiouny;
Abstract
SUMMARY
T
he brachial plexus is formed by primary ventral rami of C5, C6, C7, C8 and T1.
Brachial plexus block indicated for upper limb surgery, post-operative analgesia and chronic pain management.
Brachial plexus block can be divided broadly into interscalene, supraclavicular, infraclavicular and axillary approaches.
Conventional brachial plexus block techniques are performed without visual guidance and are highly dependent on surface anatomical landmarks for localization of neural structures. It is, therefore, not surprising that a reported failure rate of up to 20% occurs because of incorrect needle and/or local anesthetic placement. Multiple trial and error attempts at needle placement lead to operator frustration, unwarranted patient pain and time delay in the operating room.
Imaging technology such as MRI and CT scan can successfully localize neural structures. However, ultrasound is likely the most practical imaging tool for assisting nerve blocks as it is portable, moderately priced and non-invasive without radiation risk.
Ultrasound is a form of mechanical sound energy that travels through a conducting medium (e.g., body tissue).
