Laser-uvulopalatoplasty (LUPP) under local anesthesia: effective, safe and comfortable

Area of Science:

• Otolaryngology
• Sleep Medicine
• Surgical Anesthesiology

Background:

• Laser-uvulopalatoplasty (LUPP) is a less invasive alternative to conventional uvulopalatopharyngoplasty for treating snoring caused by lax palates.
• Patient discomfort and side effects like hypersalivation during LUPP under local anesthesia are not well-documented.
• The role of anticholinergic premedication in mitigating these periprocedural issues requires investigation.

Purpose of the Study:

• To evaluate patient discomfort during laser-uvulopalatoplasty (LUPP) performed under local anesthesia.
• To assess the effectiveness of morphine-scopolamine premedication versus morphine alone in preventing peroperative hypersalivation, bradycardia, and nausea.
• To compare patient satisfaction with sedation and pain relief between the two premedication groups.

Main Methods:

• A prospective study of 53 consecutive patients undergoing LUPP at a day care unit.
• Patients were randomized to receive either morphine and scopolamine or morphine alone as premedication.
• Peroperative salivation, bradycardia, and nausea were recorded; patients later reported on mouth dryness, sedation, and pain relief.

Main Results:

• Over 80% of patients reported insignificant pain, primarily associated with local anesthetic injection or insufficient premedication.
• The morphine-scopolamine group showed significantly reduced hypersalivation (p < 0.01) compared to the morphine-alone group.
• Morphine-scopolamine also provided significantly better sedation and analgesia (p < 0.05).

Conclusions:

• Laser-uvulopalatoplasty is a well-tolerated procedure for snoring with minimal patient discomfort.
• Anticholinergic premedication with scopolamine, in combination with morphine, is superior in managing hypersalivation and enhancing patient comfort during LUPP.
• LUPP demonstrates efficacy comparable to other laser procedures for snoring treatment.
