胃肠道低张双对比检查因能提高诊断之准确性,在成人中已广泛应用,也期望施用于儿童。抗胆硷能药物如Probathine 及Buscopan 都有副作用,而胰高糖素则较安全而有效,又无副作用,其作用期与所用剂量有关,剂量大强心,中剂量能升高血糖,小剂量可使胃肠道平滑肌弛缓。胰高糖素曾用于儿童肠套叠钡灌肠之整复,所用剂量为50微克/公斤体量。为诊断儿童疾病则此剂量较大已超过成人之钡餐检查时所用总量50—100微克。本文目的在于研究减少儿重所用剂量。钡餐检查需要观察食管——胃交界处和幽门的功能,因此当钡进入十二指肠球部以后再行注射胰高糖素,在钡灌肠时不需要检查结肠平滑肌之功能,因此在检查之始即可注射,静脉注射后15-30秒可出
Gastrointestinal hypotension double contrast test can improve the diagnostic accuracy, has been widely used in adults, but also expected to be applied to children. Anticholinergic drugs such as Probathine and Buscopan have side effects, while glucagon is safer and more effective, with no side effects. The duration of action depends on the dosage used. May make gastrointestinal smooth muscle relaxation. Glucagon has been used in children with intussusception barium enema of the whole complex, the dose used is 50 micrograms / kg body weight. This dose, which is more than 50-100 micrograms for bariatric meals in adults, is used to diagnose pediatric disease. The purpose of this article is to study the dose to reduce weight. Barium meal examination need to observe the esophageal - gastric junction and pylorus function, so when the barium into the duodenal bulb after injection of glucagon, barium enema does not need to check the function of colon smooth muscle, so in the inspection The beginning can be injected, 15-30 seconds after intravenous injection can be
