Some patients with constipation, especially some older elderly people, have difficulty with stool often use corkage, but often the effect is not good, requiring enemas, in fact, here are some details that should be noted that affect the effectiveness of the use of corkage. The main component of the open plug is glycerin or sorbitol, magnesium sulfate, each 20 ml, the role is to loosen the stool and lubricate the intestines. Most patients are often squeezed into one because of the desire to go to the stool, but the discharge is still a cork, no stool. This is because the effect of the open plug has not yet fully worked, that is, it has not loosened the stool. Therefore, the correct method is to squeeze in 3-4 corkage each time, and as deep as possible, and then lie down for 20 minutes, so that its contact with the stool becomes softer, then it will be easier to defecate again.
