Does pediatric smog progress quickly? Many people may not be familiar with what smog is, and the name makes it seem like a very dreamy disease. However, smog is not as dreamy and beautiful as one might think, and it can lead to death. Once a child is diagnosed with smog, he or she should be treated promptly to avoid unnecessary risks. What can smog lead to: Smog can lead to brain hemorrhage, cerebral ischemia, and brain infarction. The symptoms of smog are mainly classified as cerebral ischemia and cerebral hemorrhage. Cerebral ischemia caused by narrowing of blood vessels can cause (headache, dizziness, lack of concentration). If it is more severe, it may cause (numbness of limbs and weakness of limbs). If more severe, it may cause (hemiparesis and aphasia, etc.). Brain hemorrhage caused by excessive dilatation of blood vessels may cause (sudden severe headache with nausea and vomiting) and other symptoms. The main cause of death from smog is also due to cerebral hemorrhage. Also smog disease may lead to cerebral infarction, which may cause (visual field defects, aphasia, etc.) If the manifestation is cerebral hemorrhage, the patient may die within three or five days even if ventricular puncture and drainage surgery is done. If the manifestation is ischemia, the patient’s condition will progress rapidly within five years. The dangers of worsening smog: as just mentioned, the onset of smog can lead to cerebral hemorrhage, if, say, the patient is seen with ischemic symptoms. Without intervention and treatment, in five years or so, the patient’s condition will progress rapidly, and the manifestations of cerebral ischemia will become more and more obvious, and there is a possibility of a large cerebral infarction. In some patients, brain hemorrhage is the primary reason for the visit, and the patient has significant impairment of consciousness, confusion, coma, and a large amount of brain hemorrhage occurs. In this case, the treatment effect may not be good, and even if the operation of ventricular puncture and drainage is done, the patient’s condition will continue to deteriorate and there is a possibility that he or she will die within three or five days. Therefore, in principle, smog should be treated as soon as it is detected in order to control the progression of the disease.
