Postoperative subcutaneous effusion of meningioma needs to be treated according to the specific situation. If it is a small amount of fluid, it can be left untreated; if it is a large amount of fluid, it can be treated with hot compresses and physiotherapy; if it is a large amount of fluid, it should be treated accordingly by doctor. 1. A small amount of fluid: if a small amount of subcutaneous fluid, generally do not have to deal with, because most of the self-absorption. 2. Large amount of fluid: If the amount of subcutaneous fluid is large, hot compresses and physical therapy can be applied to promote the absorption of subcutaneous fluid. 3. Large amount of fluid: If the above measures do not improve, and the amount of subcutaneous fluid is relatively large, it is expected to be difficult to self-absorption. Subcutaneous aspiration or incision with negative pressure drain can be used. (1) Subcutaneous puncture and suction: Promptly consult a doctor for subcutaneous puncture and suction, and then apply pressure bandage. At the same time, oral antibiotics should be taken after the operation to prevent infection, such as ceftriaxone. (2) Cutting and placing negative pressure drainage tube: if the repeated puncture treatment mentioned above is ineffective, negative pressure drainage tube can be cut and placed to carry out negative pressure suction, but the aseptic conditions must be strict to avoid intracranial infection caused by subcutaneous infection. It can be seen that postoperative subcutaneous effusion of meningioma needs to be dealt with according to the specific situation, and when it can not be absorbed by itself, it is necessary to consult the doctor in time to choose the appropriate treatment method.
