Summary

Intertransverse process block (ITPB) is a thoracic nerve block technique where the LA is injected into the thoracic "intertransverse tissue complex" posterior to the superior costotransverse ligament (SCTL). It may be an attractive alternative to a TPVB for unilateral surgery on the thorax, when considering the risk for pleural puncture, since it does not require direct needle access to the thoracic paravertebral space. However, although ITPB is ultrasound guided, the LA is frequently injected using surrogate bony landmarks in the sagittal sonogram, and in most cases without even identifying the SCTL.

Detailed description

The knowledge regarding the spread of local anesthetic is a major prerequisite for a safe and effective use of all regional anesthetic methods in clinical practice. The primary outcome is the spread of injectate which will be evaluated on axial three-dimensional MRI with contrast medium. The secondary outcome is the sensory dermatomal blockade of this novel ITPB block.

Conditions

• Intertransverse Process Block
• Thoracic Nerve Block
• Thoracic Paravertebral Block

Interventions

Type	Name	Description
PROCEDURE	Intertransverse process block	The ITPB block at T5-6 will be performed with a mixture of local anesthetic with MRI contrast 0.5% bupivacaine 10 ml and 0.5 ml contrast in concentration 3.09 mmol/l. Volunteers will be moved to MRI machine and imaged in a supine position for their whole thoracic spine. This process will last about 45-60 minutes.
