Background: The necessity of nasal packing for patients who undergo endoscopic nasal surgery remains controversial concerning hypoxic episodes during sleep. This study was designed to characterize patients with sleep disturbance during nasal packing.
Methods: The patients were evaluated for nasal resistance using the anterior active rhinomanometric test and for oxygen saturation by pulse oxymetry before and after surgery.
Results: Thirty-five patients (mean age: 45.4 ± 16.7 years old, mean BMI: 23.6 ± 2.6 kg/m2) underwent nasal surgery and received bilateral total nasal packing. Nineteen patients with nasal packing showed decreased oxygen saturation (Worsened group), whereas improvement of oxygen saturation during nasal packing was recognized in 16 patients (unchanged group). BMI and preoperative rhinomanometric test showed significantly higher scores in the unchanged group than in the worsened group.
Conclusions: Oxygen saturation during postoperative nasal packing (PNP) should be monitored more carefully in patients with low body mass index (BMI) or preoperative low nasal resistance of air flow.
