Nasal obstruction causes abnormal breathing patterns during sleep which often result in hypoxaemia. We studied the effect of nasal obstruction on arterial oxygen saturation in 20 healthy patients undergoing elective surgery which required bilateral nasal packing. Ten patients were subject to complete nasal obstruction while the remaining half had the obstruction relieved by the insertion of nasal cannulae. We found that nasal obstruction did not have any detrimental effect on the already low incidence of oxygen desaturation. There was no effect of the cannulae on the degree or frequency of hypoxaemia, although they did appear to improve the quality of sleep during the first postoperative night. They were more comfortable by day than simple packing alone and no adverse effects were observed.
鼻阻塞会导致睡眠期间呼吸模式异常，常引发低氧血症。我们研究了鼻阻塞对20例接受择期手术且需要双侧鼻腔填塞的健康患者动脉血氧饱和度的影响。10例患者完全鼻阻塞，其余一半患者通过插入鼻插管缓解阻塞。我们发现鼻阻塞对本就较低的氧饱和度降低发生率没有任何不利影响。插管对低氧血症的程度或频率没有影响，不过它们似乎确实改善了术后第一晚的睡眠质量。与单纯填塞相比，白天使用插管更舒适，且未观察到不良反应。
