0812 Inconsistent improvements of neurocognitive function after adenotonsillectomy: a pediatric sleep-disordered breathing cohort study

Abstract Introduction Adenotonsillectomy (AT) is the most common surgical treatment for pediatric obstructive-sleep-apnea (OSA) with fair effectiveness. There are still controversies about improvement of neurocognitive function after AT. This study investigates changes AT in preschool and school age children OSA, including intelligence attention, explore inconsistent improvements by comparing different evaluation tools. Methods 130 OSA were recruited, 30 100 school-age children. 125 participants underwent clinical evaluation, polysomnography (PSG), before 1-year Preschool received Wechsler-Preschool-and-Primary-Scale-of-Intelligence (the revised IV edition, WPPSI-R WPPSI-IV) Conners’-Kiddie-Continuous-Performance-Test (K-CPT) while Wechsler-Intelligence-Scale-for-Children 3rd 4th WISC-III WISC-IV), Conners’-continuous-performance-test-II (CPT-II), Questionnaires Obstructive-Sleep-Apnea-Questionaire-18 (OSA-18) Child-Behavior-Checklist (CBCL) also used. The t-test chi-square test analysis was used to compare data between children, PSG, CPT variables, OSA-18 CBCL AT, as well group differences changes. Correlation variables performed using Pearson-Correlation investigate factors related response. Results No significant difference found except (p=0.000) less male gender (p=0.049). 21.7% had language delay, more than 80% all allergic rhinitis or high narrow palate. After both groups PSG OSA-18. change WPPSI-IV WISC-IV but WISC-III. CPT-II Hit-reaction-time-standard-deviation positively correlates PSG. Conclusion Besides sleep apnea subjective emotion behavior, can be beneficial attention. Some tools may not sensitive enough detect function, selection proper important design. Support (if any)
