Effect of Adenotonsillectomy on Parent-Reported Sleepiness in Children with Obstructive Sleep Apnea.

ABSTRACT: STUDY OBJECTIVES:To describe parental reports of sleepiness and sleep duration in children with polysomnography (PSG)-confirmed obstructive sleep apnea (OSA) randomized to early adenotonsillectomy (eAT) or watchful waiting with supportive care (WWSC) in the ChildHood Adenotonsillectomy Trial (CHAT). We hypothesized children with OSA would have a larger improvement in sleepiness 6 mo following eAT compared to WWSC. METHODS:Parents of children aged 5.0-9.9 y completed the Epworth Sleepiness Scale modified for children (mESS) and the Pediatric Sleep Questionnaire-Sleepiness Subscale (PSQ-SS). PSG was performed at baseline and at 7-mo endpoint. Children underwent early adenotonsillectomy or WWSC. RESULTS:The mESS and PSQ-SS classified 24% and 53% of the sample as excessively sleepy, respectively. At baseline, mean mESS score was 7.4 ± 5.0 (SD) and mean PSQ-SS score was 0.44 ± 0.30. Sleepiness scores were higher in African American children; children with shorter sleep duration; older children; and overweight children. At endpoint, mean mESS score decreased by 2.0 ± 4.2 in the eAT group versus 0.3 ± 4.0 in the WWSC group (P < 0.0001); mean PSQ-SS score decreased 0.29 ± 0.40 in eAT versus 0.08 ± 0.40 in the WWSC group (P < 0.0001). Despite higher baseline sleepiness, African American children experienced similar improvement with adenotonsillectomy than other children. Improvement in sleepiness was weakly associated with improved apnea-hypopnea index or oxygen desaturation indices, but not with change in other polysomnographic measures. CONCLUSIONS:Sleepiness assessed by parent report was prevalent; improved more after eAT than after WWSC; and was not strongly predicted by sleep disturbances identified by PSG.

Project description:Importance:Adenotonsillectomy (ATE) is the primary surgical method for treating obstructive sleep apnea (OSA) in children. However, children with severe OSA have an increased risk for residual OSA after ATE. Previous studies indicate that adenopharyngoplasty (APP), a modified ATE with closure of the tonsillar pillars, might improve the surgical outcome, but the overall evidence is weak. Objective:To determine whether APP is more effective than ATE for treating severe OSA in otherwise healthy children. Design, Setting, and Participants:A blinded randomized clinical trial was conducted at the otorhinolaryngology department at Karolinska University Hospital, Stockholm, Sweden. Eighty-three children, aged 2 to 4 years, with an obstructive apnea-hypopnea index (OAHI) score of 10 or higher, were randomized to APP (n = 36) or ATE (n = 47). Participants were recruited from December 1, 2014, through November 31, 2016. Interventions:Adenotonsillectomy was performed in all 83 patients in both groups by the cold steel technique. The APP group also underwent closure of the tonsillar pillars with 2 inverted sutures on each side. Main Outcomes and Measures:The primary outcome was the difference between the groups in OAHI score change before and after surgery. A higher score indicates worse problems and a score of 10 or higher is defined as severe OSA. The outcome was evaluated per protocol and with intention-to-treat analysis. Secondary outcomes were other polysomnography variables and the Obstructive Sleep Apnea-18 (OSA-18) questionnaire (possible total symptom score range, 18-126; higher scores indicate worse quality of life). Polysomnography was performed and the OSA-18 questionnaire was completed preoperatively and 6 months postoperatively. Results:A total of 83 children (49 [59%] boys; mean [SD] age, 36.6 [9.2] months) were included in the study. Of these, 74 (89%) (APP, n = 30; ATE, n = 44) completed the study. The mean (SD) preoperative OAHI score was 23.8 (11.8) for APP and 23.8 (11.5) for ATE. Both the APP and ATE groups had a significant decrease in mean OAHI score after surgery (-21.7; 95% CI, -26.3 to -17.2; and -21.1; 95% CI, -24.5 to -17.7, respectively), but there was no significant difference between the groups (0.7; 95% CI, -4.8 to 6.1). Furthermore, no significant differences between the groups were seen regarding other polysomnography variables (eg, respiratory distress index: mean, 0.6; 95% CI, -5.0 to 6.3) or the OSA-18 questionnaire (eg, total symptom score: -0.5; 95% CI, -13 to 12). One patient from each group was readmitted owing to postoperative bleeding, but no other complications were seen. Conclusions and Relevance:This trial did not show that APP was more effective than ATE alone to treat otherwise healthy children with severe OSA. This finding suggests that ATE should continue to be the primary treatment for OSA in children. Trial Registration:ClinicalTrials.gov Identifier: NCT02315911.

Project description:Hypertension in childhood may continue into adulthood and lead to adverse cardiovascular outcomes. Evidence suggests that adenotonsillectomy for childhood obstructive sleep apnea (OSA) may be associated with blood pressure (BP) improvement. However, how adenotonsillectomy is associated with BP in hypertensive and nonhypertensive children with OSA remains unclear.To investigate disparities in BP changes after adenotonsillectomy in hypertensive and nonhypertensive children with OSA.From January 1, 2010, to April 30, 2016, children (aged <18 years) with symptoms of OSA treated at National Taiwan University Hospital were enrolled in this retrospective case series study.Children underwent polysomnography for diagnosis of OSA (apnea-hypopnea index >1). All children with OSA underwent adenotonsillectomy.Preoperative and postoperative overnight polysomnographic data were obtained. Office BP was measured in a sleep center before (nocturnal BP) and after (morning) polysomnography.A total of 240 nonobese children (mean [SD] age, 7.3 [3.0] years; 160 [66.7%] male and 80 [33.3%] female) with OSA were recruited. Postoperatively, the apnea-hypopnea index decreased significantly from 12.1 to 1.7 events per hour (95% CI of difference, -12.3 to -8.4 events per hour). The whole cohort had a significant decrease in nocturnal diastolic BP (66.9 to 64.5 mm Hg; 95% CI of difference, -4.1 to -0.7 mm Hg) and morning diastolic BP (66.9 to 64.4 mm Hg; 95% CI of difference, -4.2 to -0.8 mm Hg). The number (percentage) of patients with diastolic BP in the greater than 95th percentile decreased significantly nocturnally (48 [20.0%] to 33 [13.8%]; 95% CI of difference, -12.1% to -0.4%) and in the morning (52 [21.7%] to 34 [14.2%]; 95% CI of difference, -13.6% to -1.4%). Postoperatively, hypertensive children had a significant decrease in all BP measures, including mean (SD) nocturnal and morning systolic BP (nocturnal: 107.5 [8.6] mm Hg; morning: 106.0 [9.4] mm Hg), systolic BP index (nocturnal: -4.3 [8.6]; morning: -5.7 [8.5]), diastolic BP (nocturnal: 65.1 [11.5] mm Hg; morning: 64.4 [10.1] mm Hg), and diastolic BP index (nocturnal: -10.7 [17.3]; morning: -11.6 [15.7]), whereas the nonhypertensive group had a slight increase in nocturnal systolic BP (103.8 to 105.9 mm Hg; 95% CI of difference, 0.4-3.9 mm Hg). A generalized estimating equation model for subgroup comparisons revealed that children with hypertension, compared with those without, had greater improvement in all BP measures.Hypertensive children with OSA had a significant improvement in BP after adenotonsillectomy. Hypertensive children with OSA should be screened and treated by adenotonsillectomy because proper treatment not only eases OSA symptoms but also potentially prevents future cardiovascular and end-organ disease.
