title: Incidence of oxygen desaturation during oral surgery outpatient procedures.
abstract: The frequency, severity, and duration of oxygen desaturation during oral surgical procedures in outpatients was measured. Sixty patients divided into six groups received either lidocaine; lidocaine, diazepam, and meperidine; lidocaine, diazepam, meperidine, and headphone music; lidocaine, diazepam, meperidine, and nitrous oxide; lidocaine, diazepam, meperidine, methohexital, and nitrous oxide; or lidocaine and nitrous oxide. Forty-three percent of the 30 patients who did not receive supplemental oxygen experienced clinically significant oxygen desaturation (greater than 5%) with a mean duration of 4.6 minutes. Only 13% of the patients who received supplemental oxygen had significant desaturation ranging from ten seconds to 12.3 minutes with a mean duration of 1.4 minutes. An unexpected finding was hypoxia in patients receiving only lidocaine anesthesia.
