There are two types of nodules in the lungs, one is the recovery period after inflammation, when the pneumonia is improving, it is not inflammation on the first day, and the next day it is all gone, it is disappearing layer by layer, gradually decreasing, becoming scattered, and then slowly disappearing. In the process of disappearing, there are some nodules that are slow to disappear, which are generally called inflammatory nodules, and they also gradually disappear. However, at this time, it is no longer the acute progressive stage of pneumonia, and most of the preliminary anti-inflammatory and anti-inflammatory work has been done, so there is no real point in giving anti-inflammatory drugs at this time. The better treatment at this time is to help drain the phlegm, and phlegm medicine infusion into the seems not too necessary, and the effect of oral phlegm medicine will be better, really can not nebulization effect is also good, there is no need to infusion. The other kind is hyperplastic nodules, which may be due to the inhalation of polluted air or long-term chronic smoking, as well as short-term exposure to toxins, which stimulates the production of hyperplastic nodules in the lungs, and the development of such nodules is further aggravated by continuous exposure to air pollution, and its development is also relatively slow, so there is no need to go to the infusion. What is the infusion? The infusion of saline is useless as the body is in good condition at that time and can also eat and drink normally. It is even more meaningless to give antibiotics. Generally, when there is this kind of hyperplastic nodule, there is no problem with the early blood check, so it is useless to give antibiotics, so when there is a nodule, the infusion method is usually not chosen.
