Abstract：
OBJECTIVE: Pediatric sleep apnea begins in toddlerhood when sleep is vital for neurocognitive development and rapid somatic growth. As polysomnography (PSG) can be challenging in this age group, this study described the first PSG for children aged 2 to 6 years old in regards to completion and risk-factors for intolerance.
METHODS: Single center chart review in a pediatric-only hospital-based sleep center.
RESULTS: Of the 342 children age 2 to 6 years old, 99.5% completed the study and 56% cooperated with the full hook-up; the nasal monitors were the least tolerated. Children who did not achieve a full hook-up slept 0.7 h fewer (p = 0.04), woke up more often (p = 0.015), and took 15 min longer to fall asleep (p = 0.012). Younger age and having autism were independent risk factors for poor tolerance.
CONCLUSIONS: The majority of pre-schoolers tolerated their first PSG. Interventional trials to increase PSG success in this population should prepare those under 3-years-old and with sensory processing issues to cooperate with nasal monitors.

摘要：
目的：小儿睡眠呼吸暂停始于幼儿时期，此时睡眠对神经认知发育和躯体快速生长至关重要。由于多导睡眠图（PSG）在这个年龄段可能具有挑战性，这项研究描述了2~6岁儿童在完成和不耐受风险因素方面的首次PSG.
方法：在仅儿科医院的睡眠中心进行单中心图表回顾。
结果：在342名2至6岁的儿童中，99.5％的人完成了研究，56％的人配合了完整的连接；鼻监护仪的耐受性最低。未达到完全连接的儿童睡眠时间减少0.7小时（p=0.04），醒来更频繁(p=0.015)，需要15分钟才能入睡（p=0.012）。年龄较小和患有自闭症是耐受性差的独立危险因素。
结论：大多数学龄前儿童耐受他们的第一次PSG。在该人群中增加PSG成功率的介入试验应准备3岁以下且存在感官处理问题的患者与鼻监护仪合作。
