Accuracy of parental perception of nighttime breathing in children with Down syndrome after adenotonsillectomy.

STUDY OBJECTIVES

Clinical practice guidelines recommend screening all children with Down syndrome for obstructive sleep apnea with polysomnography by age 4 years. Because persistent obstructive sleep apnea (obstructive apnea-hypopnea index > 1 event/h) following adenotonsillectomy (T&A) is common in children with Down syndrome, it is important to know whether clinicians can rely on parental assessment postoperatively. The primary objective is to identify accuracy of parental perception of nighttime breathing following T&A compared with preoperative assessment.

METHODS

Patients with Down syndrome who underwent T&A along with polysomnography prior to and after the surgical procedure were included. Parents completed a 3-question pre- and postsurgery survey regarding nighttime symptoms. The responses were categorized into 3 groups: infrequent (< 3 nights/wk), sometimes (> 3 nights/wk but < 6 nights/wk), or frequent (≥ 6 nights/wk) on at least 1 question. The primary end point was identifying the accuracy of parental perception of nighttime breathing in children with Down syndrome following T&A.

RESULTS

A total of 256 children met inclusion criteria, of which 117 (46%) were included. A total of 71 (68%) children had an obstructive apnea-hypopnea index > 5 events/h preoperatively compared with 55 (47%) postoperatively. There was no association between parents' perception of symptoms and obstructive sleep apnea categorization postoperatively ( > .05) or of parents' perception of symptoms improving and obstructive sleep apnea categorization improving postoperatively ( > .05).

CONCLUSIONS

Despite previous experience, parents are unable to predict nighttime breathing patterns following a T&A. We recommend obtaining a polysomnogram rather than relying on parental assessment to determine whether a T&A has been successful.
