摘要
objective: to evaluate the effect of adenotonsillectomy on oxygen saturation measured through nocturnal pulse oximetry in children with sleep disordered breathing. methods: a pre- and post-intervention study was carried out using nocturnal pulse oximetry. the study involved 31 children who were suspected of having sleep disordered breathing and had been referred for adenotonsillectomy. results: a total of 27 children completed the study. the mean age was 5.2 ㊣ 1.8 years, and 18 (66.7%) of them were male. upon physical examination, 23 (85.2%) of the children presented class iii or class iv hyperplasia of the palatine tonsils. there was significant improvement in the post-operative period over the pre-operative period in terms of the oxygen desaturation rate (or = 0.65; 95% ci: 0.5-1.3 vs. or = 1.63; 95% ci: 1.1-2.4; p %26lt; 0.001). conclusion: adenotonsillectomy significantly improved oxygen saturation, as measured through nocturnal pulse oximetry, in children with sleep disordered breathing.
