Medial Versus Lateral Approach in Ultrasound (US)-Guided Supraclavicular Block
Medial vs. Lateral Approach to Ultrasound-Guided Supraclavicular Block: A Prospective Randomized Controlled Trial

The ultrasound guided supraclavicular block is a peripheral nerve block which is considered safe, has a fast onset, is dense and provides complete block of the nerves supplying the hand, forearm and arm. However retrospective studies done at Toronto Western Hospital have highlighted the fact that most commonly the ulnar nerve fibres (responsible for sensations in the ring finger, little finger and the corresponding part of hand), sometimes escape this block and need additional supplementary block at a distal peripheral nerve site. It is a confusing fact since all nerve fibres are compactly arranged in a sheath at the supraclavicular level. The local anaesthetic agent at this level should be equally distributed among all nerve fibres. The purpose of this study is to compare two different approaches (medial and lateral) adopted by our clinicians to perform this block and to test the effectiveness of each approach for successful ulnar nerve fibre blockade.

Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Single Blind (Outcomes Assessor)
Primary Purpose: Treatment
Hand or Arm Surgery
  • Procedure: Lateral-to-Medial Approach
    Approach of the needle to administer the brachial plexus nerve block will be done in a lateral-to-medial direction.
  • Procedure: Media-to-Lateral Approach
    Approach of the needle to administer the brachial plexus nerve block will be done in a medial-to-lateral direction.
  • Experimental: Lateral-to-Medial Approach
    Needle approach to the brachial plexus nerves will be made using a lateral-to-medial direction.
    Intervention: Procedure: Lateral-to-Medial Approach
  • Experimental: Medial-to-Lateral Approach
    Needle approach to the brachial plexus nerves will be made using a lateral-to-medial direction.
    Intervention: Procedure: Media-to-Lateral Approach
