ABSTRACT
OBJECTIVE: Studies have shown a high prevalence of sleep-disordered breathing (SDB) among children with myelomeningocele (MMC), but there are few published data on the longitudinal care of these patients. The objective of this study was to determine the effectiveness of standard treatments for SDB in children with MMC.
METHODS: The authors analyzed records from three multidisciplinary spina bifida clinics to identify all patients with both MMC and SDB diagnosed by polysomnography (PSG). The primary outcome of this study was a change in apnea-hypopnea index (AHI; the number of apneic or hypopneic events per hour of sleep) before and after clinically recommended SDB treatments. Clinical and demographic variables were recorded and evaluated for possible association with posttreatment improvement of AHI. Analysis included change in AHI (a continuous variable) and whether SDB improved (defined as an AHI < 2.5 or decrease of AHI by ≥ 50% from baseline).
RESULTS: Seventy-one eligible patients (aged 2 days-21 years, 52% male) had an initial AHI > 2.5 and had follow-up PSG after treatment for SDB. The mean AHI decreased from 20.5 (SD 21.6) at baseline to 11.6 (SD 15.7) after treatment (p = 0.0006). Children treated with supplemental oxygen and with continuous positive airway pressure had improvement on PSG (18 of 25 and 12 of 18, respectively). Children treated with adenotonsillectomy were less likely to improve (7 of 19). Forty-one patients (58%) improved from a baseline AHI > 2.5 to an AHI < 2.5 after treatment.
CONCLUSIONS: Children with MMC and SDB who undergo standard SDB treatments guided by pediatric sleep medicine physicians show improvement in PSG parameters after treatment.
