Hydrocephalus after minimally invasive surgery is considered to be related to poor circulation of cerebrospinal fluid, malabsorption of cerebrospinal fluid and infection factors, and can be alleviated by cooperating with the doctor to choose puncture and fluid extraction, medication intervention, home care and other ways. 1. Puncture and fluid extraction: mainly for patients with poor cerebrospinal fluid circulation and malabsorption, which will cause localized fluid accumulation and hydrocephalus. Early treatment with puncture and fluid extraction can be chosen, and the symptoms of hydrocephalus will be gradually relieved. If the change of fluid accumulation is not obvious, tubes can be placed to drain the fluid if necessary. 2. Pharmacological intervention: mainly for postoperative hydrocephalus caused by infectious factors, can cooperate with the doctor to choose anti-infective drugs, commonly used drugs include amoxicillin, cefixime, etc. For patients with moderate hydrocephalus, it is recommended to use the following medicines: amoxicillin, cefixime, etc. For moderate hydrocephalus patients, if necessary, can cooperate with the doctor to choose mannitol, glycerol fructose and other drug therapy. 3. Family care: patients with hydrocephalus after minimally invasive surgery should usually have a light diet, do not eat spicy food, keep a relaxed mood, do not be anxious and nervous. Patients with hydrocephalus after minimally invasive surgery should, after diagnosis, actively cooperate with doctors to give corresponding treatment and therapy according to their own conditions.
