Brain tumor is a serious life-threatening disease that can be devastating to both the patient and the patient’s family. Brain tumor is higher in early stage, and once the condition deteriorates, the consequences are unimaginable. Professor Mao Renling will introduce it to you and hope you can pay attention to it. The harm of brain tumor to the body are as follows: 1.Destructive effect: especially malignant tumor, metastatic tumor this kind of tumor is invasive growth, so that the normal brain tissue is seriously damaged and the function of brain tissue is lost. 2. Compression: Mostly seen in benign tumors, but also in malignant tumors, tumors constitute compression to normal brain tissues, causing local ischemia and degeneration, resulting in impairment of normal functions. 3.Brain edema: tumor produces a lot of toxins causing edema and swelling of brain, leading to increase of cranial pressure. 4. Increase of tumor volume: It will affect the cerebrospinal fluid circulation and cause hydrocephalus plus cerebral edema, which will increase the cranial pressure abnormally and exceed the ability of cranial cavity to reward, and affect the respiratory and heartbeat center and cause death. What do I need to pay attention to after brain tumor recovery? 1.Keep the environment quiet and comfortable, avoid noise, minimize the number of visitors, make the staff “four light”, ventilate and disinfect the air regularly, and forbid patients and their families to talk loudly and smoke in the ward. If the child is young and needs parental care, he/she is worried about being separated from his/her parents and has a fear of the unfamiliar environment in the hospital. Parents are allowed to accompany the patient. 2.Do not go out as much as possible, if you go out, someone should accompany you, and the ground should not be too wet to prevent falls and injuries. 3.Elevate the head of the bed 15°～30° when lying down to facilitate intracranial venous reflux, reduce intracranial pressure, keep the airway open, such as vomiting, pay attention to the side of the head to prevent vomit from being accidentally inhaled into the airway and causing asphyxia. Those with consciousness disorders should prevent nasopharyngeal secretions from flowing into the respiratory tract to avoid causing airway obstruction and pulmonary infection. When the patient’s sputum is sticky, pat the back or ultrasonic nebulization or steam inhalation. 4.Patients with limb dysfunction should be helped to move their limbs passively to reduce dysfunction and prevent muscle atrophy. The above is the answer to your question, I hope it will be helpful to you.
