明胶海绵作为止血剂在临床上比较常用。我们试用碳酸氢铵作为明胶海绵制备过程中的发泡剂,取得了较好的效果。现介绍如下:一、处方明胶609 甲醛溶液(3了肠g/g)6ml 碳酸氢按49 蒸馏水550ml 二、制法取明胶609,加蒸馏水400ml浸泡,待膨胀软化后,在水浴上加热溶解,然后将胶液冷却并保持20’C~30‘C备用 Gelatin sponge as a hemostatic agent is more commonly used in clinical practice. We try to use ammonium bicarbonate as a foaming agent in the gelatin sponge preparation process, and achieved good results. First, the preparation of gelatin 609 formaldehyde solution (3 g / g g) 6ml bicarbonate according to 49 distilled water 550ml Second, the system take gelatin 609, add distilled water 400ml soak until the expansion softened, heated in a water bath to dissolve, Then the glue cooling and keep 20’C ~ 30’C spare
