摘要: 采用实时超声法研究了50例成年正常男女胃液体排空.发现:其排空率随餐后时间的延长而下降,且胃底体部的变化较胃窦显着.在餐后30min内,男性受试者的胃底体部的排空率大于女性.只发现女性受试者胃底体部和胃窦的宽径与年龄呈负相关.分别拟合男女性胃底-体部随餐后时间变化的数学模型.

Abstract: Gastric emptying of 500 mLwarm water(37 ℃)was studied by real time ultrasonography in 50 healthy volunteers. The emptying rate was found to be decreased with the time after meal. The change of upper gastric body(USB)is more visible than that of gastric antrum(GA). The emptying rate of USBin male was higher than in female during the first 30 minutes after meal. Anegative correlation between the age and the width of USBand GAexisted only female. Two mathematical models were developed to describe respectively the USBdecrease after meal in both sexes.

Key words: real-time ultrasound, upper stomach body, gastric antrum, emptying rate of li quid, mathmatical models
