Background: Chemical pleurodesis causes severe pain, prompting physicians to perform thoracoscopic talc poudrage under general or neuroleptanalgesia. We describe a novel method for pain control in five patients with pneumothoraces and severe chronic obstructive pulmonary disease.
Methods: Patients were premedicated with IM pethidine and IV midazolam. The pleural space was examined with the flex-rigid pleuroscope. Before talc poudrage, 250 mg lidocaine was administered via spray catheter, and pain scores measured immediately after the procedure and on postoperative days 1 and 2 were 3, 2, and 2, respectively.
Results: No complications were noted, and 30-day mortality was 0%.
Conclusion: Lidocaine via spray catheter is effective for pain control before pleurodesis.
