应用单切面超声显像法测定26例非溃疡性消化不良患者和25例正常儿童的流体餐胃动力学指标,发现NUD患儿胃排空延迟率为61.53%,胃半排空时间,胃窦收缩幅度及收缩频率:正常组是16.4+3.57min,59.06±9.86mm~2,4.08±60.55次/分。NUD组是27.08+3.43min(P<0.01),43.70±9.73mm~2(P<0.01),3.76±0.01次/分(P<0.05)。结论:胃排空延迟,胃运动功能障碍是儿童NUD症状产生原因之一,单切面超声显像法是评价胃运动功能的有效方法。
Single-slice ultrasonography was used to measure the gastric motility of 26 patients with non-ulcer dyspepsia and 25 normal children. The delayed gastric emptying rate in NUD children was 61.53%. The gastric emptying time, Systolic amplitude and systolic frequency: the normal group is 16.4 + 3.57min, 59.06 ± 9.86mm ~ 2,4.08 ± 60.55 beats / min. NUD group was 27.08 + 3.43min (P <0.01), 43.70 ± 9.73mm2 (P <0.01), 3.76 ± 0.01 beats / min (P <0.05). Conclusion: Delayed gastric emptying and gastric motility dysfunction are one of the causes of NUD symptoms in children. Single-slice ultrasound imaging is an effective method to evaluate gastric motor function.
