Sleep-disordered breathing (SDB) may significantly impact the course of medical illness in hospitalized children. Polysomnography (PSG) is the gold standard for establishing diagnosis of SDB, but its availability is limited. The aim of this study was to explore the feasibility and utility of level III portable sleep studies in hospitalized children with SDB.
A retrospective study was conducted at a tertiary hospital over the preceding 2 years in hospitalized children < 18 years who had undergone a level III sleep study using the Nox T3 system. The information obtained included demographic data, comorbidities, indication for admission and sleep study, time interval between the study ordered and done, adequacy of technical data from sleep study, study diagnosis, and subsequent management interventions for SDB.
A total of 51 hospitalized children had these studies; 32 were female and mean age was 4.3 years. Approximately 90% of children had significant comorbidities, including neurological and craniofacial abnormalities. The majority (80%) of studies were conducted within 24 hours of the time requested and 92.1% studies had technically adequate data for analysis. Thirty-nine (76.5%) children were identified with SDB; all but one patient underwent therapy for SDB during that same hospitalization, including supplemental oxygen (48.7%), positive airway pressure therapy (23%), surgical intervention (38.2%) or caffeine (10.2%). Twelve percent of children had more than one intervention done.
The level III portable sleep study is readily available, sufficient to diagnose SDB, and help to provide appropriate medical and/or surgical therapies in hospitalized children with complex medical conditions.
睡眠呼吸障碍（SDB）可能显著影响住院儿童的疾病进程。多导睡眠图（PSG）是诊断 SDB 的金标准，但可用性有限。本研究旨在探讨在患有 SDB 的住院儿童中使用三级便携式睡眠研究的可行性和实用性。
在过去两年中，对一家三级医院的住院儿童进行了一项回顾性研究，这些儿童年龄均<18 岁，使用 Nox T3 系统进行了三级睡眠研究。获得的信息包括人口统计学数据、合并症、住院原因和睡眠研究、从下订单到完成研究的时间间隔、睡眠研究的技术数据充足性、研究诊断以及随后针对 SDB 的管理干预措施。
共有 51 名住院儿童进行了这些研究，其中 32 名是女性，平均年龄为 4.3 岁。大约 90%的儿童存在显著的合并症，包括神经系统和颅面畸形。大多数（80%）研究在请求后的 24 小时内进行，92.1%的研究具有足够的技术数据进行分析。39（76.5%）名儿童被诊断为 SDB；除一名患者外，所有患者均在同一住院期间接受了 SDB 治疗，包括补充氧气（48.7%）、气道正压治疗（23%）、手术干预（38.2%）或咖啡因（10.2%）。12%的儿童接受了一种以上的干预措施。
三级便携式睡眠研究易于获得，足以诊断 SDB，并有助于为患有复杂疾病的住院儿童提供适当的医疗和/或手术治疗。
