Obstruktiv søvnapné hos 2 -6 år gamle barn henvist til adenotonsillektomi

Flere studier har vurdert spørreskjemaer og klinisk undersøkelse for å diagnostisere obstruktiv søvnapné (OSA) hos barn, med motstridende resultater. Forskere ved Lovisenberg diakonale sykehus, Oslo universitetssykehus og UiO undersøkte i denne studien utbredelsen av OSA blant barn henvist til adenotonsillektomi. De undersøkte om spørreskjemaene The Pediatric Sleep Questionnaire (PSQ) og OSA-18 eller klinisk undersøkelse (polysomnografi og otorhinologisk undersøkelse) kunne hjelpe til med å identifisere OSA.

Adenotonsillectomy is one of the most common surgical procedures performed in children. The indications for surgery are either frequent recurrent throat infections or hypertrophy of the tonsils/adenoid vegetation, which can cause obstructive sleep apnea (OSA). There is disagreement regarding the need for sleep studies before adenotonsillectomy to confirm a diagnosis of OSA. Several studies have evaluated questionnaires and physical examination as tools to identify OSA, with conflicting results. The aim of this study was to evaluate the prevalence of OSA among children referred for adenotonsillectomy and whether questionnaires or physical examination can help identify OSA.
This is a prospective cohort study of children aged 2-6 years, referred for adenotonsillectomy. Polysomnography and an otorhinological examination were performed. Tonsillar size and the oral cavity were graded using Friedman's classification and Mallampati score, respectively. The Pediatric Sleep Questionnaire (PSQ) and OSA-18 were also completed.
100 children were included. The prevalence of OSA was 87%, with 52% having moderate to severe OSA. The usefulness of the PSQ and OSA-18 for detecting OSA was evaluated using multiple cutoff points, but none yielded acceptable values for both sensitivity and specificity. In logistic regression analyses predicting different levels of OSA severity, age, Friedman tonsillar size and Mallampati score were weakly associated with OSA.
The prevalence of OSA is high among children referred for adenotonsillectomy and questionnaires and clinical characteristics are not sensitive enough to detect the presence or severity of OSA.
