摘　　要：对１６例健康志愿者用连续灌注导管系统进行胃十二肠测压，以了解消化间期移行性复合运动（ＭＭＣ）的规律。检测时间４～６ｈ。结果显示ＭＭＣＩ期持续时间为１２７．６±５６．４ｍｉｎ，Ⅱ期１９．９±６．１ｍｉｎ，Ⅱ期胃窦部为３．４±１．１ｍｉｎ，十二指肠为４．６±２．０ｍｉｎ，近端空肠为５．８±３．０，近端空肠与胃窦部比ｐ＜０．０１。由胃窦至空肠其Ⅲ期收缩频率呈上升趋势，波幅明显上降。ＭＭＣ平均周期为１８９．０±６９．５ｍｉｎ，Ⅲ期传导速度为４．３±１．１ｃｍ／ｍｉｎ。ＭＭＣⅠ、Ⅱ、Ⅲ期完整者１２例（７５．０％），有５例出现两次ＭＭＣⅢ期（３１．１％）。提示胃十二指肠测压技术是可用于临床以反应胃肠运动功能的可靠方法。In order to investigate the migrating motor complex (MMC) in human , 16 normal volun- teers had received fasting gastrointestinal manometry for 4-6 hrs. The results showed:the duration of phase I of MMC is 127. 6±56. 4min (x±s ) ,phase Ⅱ 19. 9±6. 1min ,phase Ⅲ 3. 4±1. 1 min at antrum,4.6±2.0 min at duodenum,5.8±3.0 min at proximal jejunum which was significantly longer than at antrum (P<0. 01 ). From antrum to duodenum ,the frequncy of the contractions is increased ,the amplitude decreased. The mean cycle of MMC was 189. 0±69. 5min,the propagation velocity of phase I activities was 4. 26±1.1cm /min 12/16 subject. had normal MMC activities (75%) ,five of them had twice phase Ⅲ of MMC (31.1%). In conclutions,the gastrointestinal manumetry provided a useful method for study- ing gastrointestinal motor function in the clinical practice.
