本文作者报告用实时超声测量饮水后胃体积随时间的变化来检测胃的排空率。方法应用 Toshiba(东芝)SAL20A 实时超声诊断仪及电视录象装置。受试者前一夜禁食,次晨饮用500ml 37℃温桔汁水,用超声探头从腹部皮肤上扫描。分别于饮水后5、10、15、20、30、40分钟各扫描1次。扫描时病人保持吸气状态。胃的体积是计算得来的,先测定胃的横断面,每间隔1cm 为一断层,记录于录象带中,以测定其面积,同时测定胃的长轴,
The authors report measuring gastric emptying rate over time using real-time ultrasound measurements of gastric volume after drinking water. Methods Toshiba (Toshiba) SAL20A real-time ultrasonic diagnostic apparatus and video recording device. The subjects were fasted the night before, the next morning with 500ml of 37 ℃ warm orange juice, with an ultrasound probe from the abdominal skin scan. Respectively after drinking 5,10,15,20,30,40 minutes each scan. The patient kept breathing during scanning. The volume of the stomach is calculated, the first determination of the stomach cross-section, each interval of 1cm for a fault, recorded in the video tape to determine the area, while measuring the long axis of the stomach,
