发泡剂是医院放射科常用的一种制剂,但是有关资料中介绍的发泡剂处方中药物配比不当。如有的资料介绍:碳酸氢钠与枸橼酸之比为1∶3,临用时分别配制成10%和30%的溶液等量服用。因配比不妥,会出现不良倾向:当碳酸氢钠过多时,会提高胃液的pH 值;当枸橼酸过多时,则会增加胃酸的酸度。 Blowing agent is a commonly used in the hospital radiology preparations, but the information on the formulation of the foaming agent in the medicine ratio is not appropriate. If any information is presented: Sodium bicarbonate and citric acid ratio of 1: 3, when used as the preparation of 10% and 30% of the solution taken in equal quantities. Due to improper ratio, there will be adverse tendencies: When too much sodium bicarbonate, gastric juice will increase the pH value; when citric acid is too much, it will increase the acidity of gastric acid.
