Summary 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.
