Nasal obstruction influences respiration during sleep, and nasal packing may be the cause of obstructive sleep apnoea. In order to investigate this phenomenon, perioperative nocturnal oxygen saturation was monitored for 3 nights with continuous, non-invasive pulse oximetry in 12 patients who had total nasal packs after septoplasty. Significant extension of nocturnal accumulated time of oxygen saturation less than 90% was demonstrated both during the first and second postoperative nights. The clinical significance of these results is as yet unknown, but the use of partial nasal packing in association with septoplasty is advocated and further investigations on nocturnal oxygen saturation are called for.
鼻阻塞会影响睡眠期间的呼吸，而鼻腔填塞可能是阻塞性睡眠呼吸暂停的原因。为了研究这一现象，对12例鼻中隔成形术后进行全鼻腔填塞的患者，采用连续无创脉搏血氧饱和度监测仪，在围手术期连续3个晚上监测夜间血氧饱和度。结果显示，术后第一晚和第二晚夜间血氧饱和度低于90%的累计时间均显著延长。这些结果的临床意义尚不清楚，但提倡在鼻中隔成形术时联合使用部分鼻腔填塞，并需要进一步研究夜间血氧饱和度情况。
