Overheating may cause terminal apnoea and cot death. Rectal temperature and breathing patterns were examined in normal infants at home during the first 6 months of life. Twenty one infants had continuous overnight rectal temperature and breathing recordings for 429 nights (mean 20.4 nights, range 7-30) spaced over the first six months of life. Periods when breathing was 'regular' were directly marked on single night records. Sleep state was determined from respiratory variables. 'Regular' breathing was a reliable marker of 'quiet' sleep (specificity 93%). The duration of 'quiet' sleep increased from 6 to 22 minutes from two weeks to three months of age and then remained static, as did the proportion of sleep spent in the quiet phase (9% to 34%). Rectal temperature fell during 66% of quiet sleep and usually rose during rapid eye movement (REM) sleep. The drop in rectal temperature was maximal at the start of quiet sleep, whereas the maximum rise during REM sleep was reached after 10 to 15 minutes. Oscillations in rectal temperature are associated with changes in sleep and breathing state. The maturation of rectal temperature patterns during the first six months of life are closely related to a maturation of sleep state and breathing patterns.
过热可能导致终末呼吸暂停和婴儿猝死。在出生后的前6个月，对正常婴儿在家中的直肠温度和呼吸模式进行了检查。21名婴儿在出生后的前6个月里，连续进行了429个晚上的直肠温度和呼吸记录（平均20.4个晚上，范围7 - 30个晚上）。在单晚记录上直接标记呼吸“规律”的时间段。根据呼吸变量确定睡眠状态。“规律”呼吸是“安静”睡眠的可靠标志（特异性为93%）。从两周到三个月大，“安静”睡眠的时长从6分钟增加到22分钟，之后保持稳定，安静睡眠阶段占总睡眠的比例也如此（从9%到34%）。66%的安静睡眠期间直肠温度下降，而在快速眼动（REM）睡眠期间通常上升。直肠温度下降在安静睡眠开始时最大，而REM睡眠期间温度上升在10至15分钟后达到最大值。直肠温度的波动与睡眠和呼吸状态的变化有关。出生后前6个月直肠温度模式的成熟与睡眠状态和呼吸模式的成熟密切相关。
