Abstract

Background: Nasal obstruction is considered a risk factor for sleep-disordered breathing (SDB), although the relationship has not been established clearly. This study explores the repercussion of total nasal packing on arterial oxygen saturation during the nocturnal resting hours and its implication in SDB.

Methods: Forty patients were subjected to total nasal packing after nasal surgery or epistaxis. In all cases the oxygen desaturation index (ODI) was monitored with and without nasal packs, and the results were compared.

Results: Thirty-seven patients (92.5%) showed poorer oxygen saturation after nasal occlusion. Of these, 19 patients (47.5%) reached pathological desaturation (ODI > or = 12). Desaturation was greater among obese subjects.

Conclusion: Total nasal packing causes significant nocturnal oxygen desaturation. This must be taken into account in the postoperative nasal packing of patients with respiratory failure, obesity, or SDB.

全鼻阻塞对夜间血氧饱和度的影响。

背景:鼻塞被认为是睡眠呼吸障碍(SDB)的危险因素，尽管两者之间的关系尚未明确。本研究探讨全鼻填塞对夜间休息时间动脉血氧饱和度的影响及其在SDB中的意义。方法:对40例鼻手术或鼻出血患者进行全鼻填塞。在所有病例中，使用和不使用鼻填充物监测氧去饱和指数(ODI)，并比较结果。结果:37例(92.5%)患者术后血氧饱和度下降。其中19例(47.5%)达到病理性去饱和(ODI > = 12)。肥胖受试者的去饱和程度更高。结论:全鼻填塞引起明显的夜间氧饱和度降低。在呼吸衰竭、肥胖或SDB患者的术后鼻填塞中必须考虑到这一点。
