Gastrointestinal (GI) motility disorders are common in children. Modern technology has enabled better understanding, monitoring and treatment of these disorders. While gastric anatomic structures are developed prenatally, myoelectric activity and motility develop after the birth. Electrogastrography (EGG) measures gastric myoelectric activity by electrodes that are positioned on the skin. The frequency of gastric waves varies between 0.5-9.0 c/min, usually between 2.0-4.0 c/min with amplitudes between 50 and 500 microV. Frequency above 4.0 c/min is called tachygastria, bellow 2.0 c/min bradygastria, and if the dominant frequency cannot be measured it is defined as gastric arrhythmia. EGG is useful for monitoring of normal gastric function, determining motoric gastric diseases in different states and for the evaluation of treatment of a disease. The method is non-invasive, cheap and safe and is easily performed. These characteristics make the method useful in pediatrics. The future of the method depends mainly on the technical improvement of measurement and data analysis which is crucial for better result interpretation.
胃肠动力障碍在儿童中很常见。现代技术使人们能够更好地理解、监测和治疗这些疾病。虽然胃的解剖结构在产前就已发育,但肌电活动和动力在出生后才发育。胃电图(EGG)通过放置在皮肤上的电极来测量胃肌电活动。胃电波的频率在0.5 - 9.0次/分钟之间变化,通常在2.0 - 4.0次/分钟之间,振幅在50至500微伏之间。频率高于4.0次/分钟称为胃动过速,低于2.0次/分钟称为胃动过缓,如果无法测量主导频率,则定义为胃节律失常。EGG有助于监测正常胃功能,确定不同状态下的胃动力疾病以及评估疾病的治疗效果。该方法无创、廉价且安全,操作简便。这些特性使该方法在儿科中很有用。该方法的未来主要取决于测量和数据分析的技术改进,这对于更好地解释结果至关重要。
