We reviewed our experience with home monitor observations of 83 preterm infants (postconceptional age, 36 to 44 weeks) who had persistent apnea, bradycardia, or cyanosis. Polygraphic recordings before discharge showed that 92% of these infants had cardiorespiratory abnormalities that included prolonged (greater than 20 s) apnea, excessive periodic breathing (greater than 15%), bradycardia (greater than 80 beats per minute), feeding hypoxemia, or elevated carbon dioxide values. At home, 70 infants had either no alarms or alarms that resolved spontaneously, while 13 (16%) had more serious episodes that required parental intervention, including mouth-to-mouth ventilation in one infant. While polygraphic studies were helpful in documenting specific cardiorespiratory abnormalities, neither these abnormalities nor the clinical characteristics of the infants identified those infants experiencing subsequent home monitor alarms requiring parental intervention. Our data suggest that some preterm infants with persistent episodes of apnea, bradycardia, and cyanosis beyond 36 weeks of postconceptional age remain at risk for future serious episodes for several months.
我们回顾了对83名患有持续性呼吸暂停、心动过缓或发绀的早产儿（孕龄36至44周）进行家庭监测的经验。出院前的多导记录显示，这些婴儿中有92%存在心肺异常，包括长时间（超过20秒）呼吸暂停、过度周期性呼吸（超过15%）、心动过缓（每分钟超过80次心跳）、喂养性低氧血症或二氧化碳值升高。在家中，70名婴儿没有警报或警报自行解除，而13名（16%）婴儿出现了更严重的发作，需要家长干预，其中一名婴儿需要进行口对口通气。虽然多导研究有助于记录特定的心肺异常，但这些异常以及婴儿的临床特征均无法识别出那些随后在家中监测时出现需要家长干预的警报的婴儿。我们的数据表明，一些孕龄超过36周后仍有持续性呼吸暂停、心动过缓发作和发绀的早产儿在数月内仍有发生未来严重发作的风险。
