    Abstract:
    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 < 0.001). CONCLUSION: Adenotonsillectomy significantly improved oxygen saturation, as measured through nocturnal pulse oximetry, in children with sleep disordered breathing.
