[Peripheral oxygen saturation during dental surgery with and without premedication]

Area of Science:

• Anesthesiology and Perioperative Medicine
• Dental Surgery
• Respiratory Monitoring

Background:

• Dental surgical procedures under local anesthesia can pose risks of hypoxemia.
• Premedication with sedatives is common but may affect respiratory function.
• Continuous pulse oximetry is crucial for monitoring oxygen saturation.

Purpose of the Study:

• To investigate the incidence and frequency of hypoxemia in adult patients undergoing dental surgery.
• To compare hypoxemia rates between patients who received premedication and those who did not.
• To assess the impact of premedication on oxygen saturation during dental procedures.

Main Methods:

• Continuous monitoring of oxygen saturation using pulse oximetry in 83 adult patients.
• Patients were divided into two groups: those receiving premedication (neuroleptic/opiate or benzodiazepine) and those without.
• Comparison of the percentage of patients experiencing oxygen desaturation and the number of hypoxemic periods.

Main Results:

• A higher percentage of patients with premedication (80%) experienced a drop in oxygen saturation compared to those without (66%).
• Patients with premedication had statistically significantly more periods of hypoxemia (1548 vs. 659).
• The specific type of premedication/sedation did not influence the number of hypoxic episodes.

Conclusions:

• Premedication significantly increases the risk and frequency of hypoxemia during dental surgical procedures.
• Patients receiving premedication require careful monitoring and management by experienced surgical teams.
• Surgeons must possess adequate clinical experience in managing emergency situations, particularly with sedated patients.
