摘要
采用实时超声法研究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－体部的变化较幽门窦显著。在餐后３０ｍｉｎ内，男性受试者的胃底－体部的排空率大于女性受试者。只发现女性受试者胃底－体部和幽门窦的宽径与年龄呈负相关。为便于今后研究，分别拟合男女性胃底－体部随餐后时间变化的数学模型。
It was performed in 50 healthy volunteers by real-time ultrasound to study the gastric emptying of 500 ml warm water (37℃). The emptying rate was found to be decreased with the time after meal. The change of upper stomach body(USB) is more visible than that of pyloric antrum(PA). The male's emptying rate of USB was higher than the female's during the first 30 minutes after meal. There were only good corrections between females' age and their width of USB and PA.Two Mathematical models were developed to describe male's and female's USB decrease after meal respectively.
