Summary

The lateral parasagittal in-plane is the current conventional approach in ultrasound-guided infraclavicular brachial plexus block. However this technique is less popular because brachial plexus at the infraclavicular level runs deeper compared to its course proximally, often give rise to impaired needle visualisation due to its steep angle of needle trajectory to the ultrasound beam. A new posterior parasagittal in-plane approach was introduced to improve needle visibility. This approach proved feasible from our case series hence the investigators would like to compare it with the conventional method in this study

Conditions

  • Brachial Plexus Block
  • Infraclavicular
  • Ultrasound Guided

Interventions

PROCEDURE

Posterior approach

The needle insertion point was over the trapezius muscle sufficiently posterior to allow the needle to pass between the clavicle and the scapula in the direction of the axillary artery. The insertion point was strictly aligned with the long axis of the ultrasound beam i.e. in-plane technique.

PROCEDURE

Conventional approach

The needle insertion point would be at the cephalad (lateral) aspect of the ultrasound probe, beneath the clavicle and medial to the coracoid process. The insertion point was strictly aligned with the long axis of the ultrasound beam i.e. in-plane technique.
