为了确定人类白天清醒时和夜间睡眠时直肠的运动模式，并将这种模式与消化间十二指肠运动复合体和睡眠周期相关联，对12名健康受试者(5名女性，7名男性；平均年龄28岁)，使用一根柔性的、非柔性的、有弹性的导管和一个位于肛肠结上方6厘米的单灌注直肠口的Arndorfer系统，通过一根灌注的口十二指肠管记录十二指肠运动，并通过脑电图确定睡眠阶段。在157小时的记录中，12名受试者中的11名在72次中发现了直肠运动波的离散爆发，称为直肠运动复合物（RMCs）。RMCs在白天禁食或进食后出现（0.2±0.1 RMCs/h），但在夜间睡眠时更容易和频繁地被发现（0.8 RMCs/h, p < 0.01）。复合物有明显的起效，平均持续时间±SEM为9.5±1.0分钟，并有明显的下降。在每个复合体中，波的平均频率为每分钟3.8±0.3次，平均振幅为19±2.7毫米汞柱。夜间复合体到复合体的间隔平均为74±15分钟。复合物与消化间期十二指肠运动复合物III期或快速眼动睡眠阶段之间没有明确的时间关联。
To identify patterns of motility in the rectum of humans during the day while awake and at night during sleep, and to correlate the patterns with interdigestive duodenal motor complexes and sleep cycles, intraluminal rectal pressure was recorded in 12 healthy subjects (five female, seven male; mean age, 28 years) using a flexible, noncompliant, silastic catheter and an Arndorfer system with a single perfused rectal port 6 cm above the anorectal junction, duodenal motility was recorded via a perfused oroduodenal tube, and sleep stages were determined electroencephalographically. Discrete bursts of rectal motor waves, called rectal motor complexes (RMCs), were identified on 72 occasions in 11 of the 12 subjects during 157 hours of recording. The RMCs were found in daytime during fasting or after feeding (0.2 ± 0.1 RMCs/hour), but were more easily and frequently identified at night during sleep (0.8 RMCs/hour, p < .01). The complexes had a distinct onset, a mean duration ± SEM of 9.5 ± 1.0 minutes, and a distinct decline. Within each complex, the waves had a mean frequency of 3.8 ± 0.3 per minute and a mean amplitude of 19 ± 2.7 mm Hg. Complex‐to‐complex intervals at night averaged 74 ± 15 minutes. No clear‐cut temporal association was present between the complexes and phase III of interdigestive duodenal motor complex or the REM stage of sleep.
