[Ultrasound guided catheterization of thoracic paravertebral space]

Area of Science:

• Regional Anesthesia
• Medical Imaging
• Pain Management

Background:

• Prolonged thoracic paravertebral block is a complex regional anesthesia technique.
• Traditionally performed using nerve stimulation.
• Ultrasound navigation offers a modern alternative for paravertebral space (PVS) verification.

Purpose of the Study:

• To detail the anatomy and technique of ultrasound-guided paravertebral space catheterization.
• To highlight the benefits of sonographic navigation in regional anesthesia.

Main Methods:

• Anatomical review of the paravertebral space.
• Description of ultrasound-guided needle insertion and catheter placement.
• Real-time needle visualization and local anesthetic distribution assessment.

Main Results:

• Ultrasound guidance facilitates identification and visualization of the PVS.
• Operator skill in real-time needle visualization is crucial for success.
• Optimized local anesthetic distribution in the PVS is achieved.

Conclusions:

• Sonographic navigation simplifies paravertebral space catheterization.
• Ultrasound guidance enhances the safety and efficacy of prolonged thoracic paravertebral blocks.
• This technique provides adequate long-term pain relief with reduced complications.
