Paravertebral block is a safe and effective technique for unilateral analgesia in both children and adults, with low failure rates and manageable complications. This study evaluated its efficacy and safety in 367 patients.

Area of Science:

Anesthesiology
Pain Management
Regional Anesthesia

Background:

Paravertebral block is a regional anesthesia technique used for thoracic and abdominal pain management.
Assessing the efficacy and safety of paravertebral blocks is crucial for clinical practice.

Purpose of the Study:

To prospectively evaluate the failure rate and complications of thoracic or lumbar paravertebral block.
To compare the outcomes in pediatric and adult patient populations.

Main Methods:

A prospective study involving 367 patients (pediatric and adult) who underwent thoracic or lumbar paravertebral block.
Data collection on block failure rates and incidence of specific complications.

Main Results:

Overall failure rate was 10.1% (10.7% in adults, 6.2% in children).

Key complications included hypotension (4.6%), vascular puncture (3.8%), pleural puncture (1.1%), and pneumothorax (0.5%).

These complication rates are comparable to alternative regional anesthesia techniques.

Conclusions:

Paravertebral block is an effective and safe method for achieving unilateral analgesia in both pediatric and adult patients.
The technique offers comparable safety and efficacy to other regional anesthesia methods like epidural or intercostal blocks.
