Comparison of injectate spread following transverse vs. sagittal <i>in-plane</i> ultrasound-guided thoracic paravertebral block: a cadaveric study.

ABSTRACT:

Background

Thoracic paravertebral block (TPVB) is a clinically valuable regional anesthesia and analgesia technique for managing postoperative acute pain and certain chronic pain conditions. There are several approaches for ultrasound-guided TPVB. However, currently it is hard to provide an evidence-based recommendation on the choice between approaches. Comparisons of injectate distribution patterns among different approaches are limited. This observational cadaveric study compared dye distribution following TPVB using transverse in-plane (TI) and sagittal in-plane (SI) ultrasound-guidance.

Methods

Ten paravertebral injections at the T6-7 were performed on five cadavers. Left side received injections with TI approach, and right side with SI approach. All inject
