To investigate the mechanism of action of the thoracic intertransverse process (ITP) block. ⋯ The space posterior to the superior costotransverse ligament, the target area for ITP blocks, has potential anatomical pathways to the thoracic paravertebral space. The costotransverse foramen and the costotransverse space provided the anatomical conduit for the anterior and intersegmental paravertebral spread of the ITP block.

Randomized Controlled TrialComparing liposomal bupivacaine plus bupivacaine to bupivacaine alone in interscalene blocks for rotator cuff repair surgery: a randomized clinical trial.
Single-injection interscalene brachial plexus blocks are used for analgesia for rotator cuff repair (RCR) but have limited duration. The value of adding liposomal bupivacaine (LB) to prolong single-injection interscalene blocks is unclear. The purpose of this trial is to evaluate the addition of LB to regular bupivacaine interscalene blocks for patients undergoing arthroscopic RCR. ⋯ LB added to bupivacaine interscalene blocks does not reduce opioid consumption within 72 hours following arthroscopic RCR.

Randomized Controlled Trial
Continuous interscalene versus phrenic nerve-sparing high-thoracic erector spinae plane block for total shoulder arthroplasty: a randomized controlled trial.
The high-thoracic erector spinae plane block (HT-ESPB) has been reported as an effective analgesic modality for the shoulder region without phrenic nerve palsy. The goal of this study was to compare the HT-ESPB as a phrenic nerve-sparing alternative to an interscalene block for total shoulder arthroplasty. ⋯ gov (NCT03807505); registered 17 January 2019.
