Summary
Ultrasound-guided paravertebral block with minimal sedation offers a safe and effective anesthesia option for radiofrequency ablation (RFA) of lung tumors. This technique allows patient communication and avoids general anesthesia for high-risk individuals.
Area of Science:
- Anesthesiology
- Pulmonology
- Interventional Radiology
Background:
- Surgical resection is standard for early lung cancer and metastases.
- Radiofrequency ablation (RFA) is a curative option for non-surgical candidates.
- Optimal anesthesia for pulmonary RFA remains debated.
Observation:
- This study evaluated ultrasound-guided thoracic paravertebral block (TPVB) with minimal sedation for pulmonary RFA.
- 17 patients underwent 19 procedures for primary lung tumors or metastases.
- TPVB was performed between T4-T8, allowing intraoperative communication and apnea.
Findings:
- TPVB was well-tolerated with no complications.
- Only two patients required additional analgesia for pleuritic pain.
- No patients needed conversion to general anesthesia, and no hemodynamic instability or desaturation occurred.
Implications:
- Ultrasound-guided TPVB is a safe and effective anesthetic for pulmonary RFA.
- This technique is suitable for high-risk patients undergoing RFA for lung tumors.
- It facilitates patient collaboration and avoids general anesthesia complications.
