There is no such thing as the simplest cerebrospinal fluid recovery. There are generally oral supplementation, intravenous supplementation, and lumbar puncture for recovery. 1. Oral supplementation: Patients can use oral rehydration salts, which can be taken directly after brewing, or glucose saline, which is absorbed by the body to achieve the effect of replenishing cerebrospinal fluid. 2. Intravenous supplementation: Intravenous injection of 5% dextrose saline or balancing solution can replenish cerebrospinal fluid relatively quickly, because these fluids can easily reach the central nervous system through the vein. 3. Lumbar puncture: Saline is injected directly into the patient’s spinal canal to increase the cerebrospinal fluid circulating in the patient’s brain. However, this method cannot be performed multiple times, and is only suitable for temporary patients if the cause of the patient’s condition cannot be removed. It is recommended that the patient undergoes a clear examination, combined with the choice of a rapid recovery of cerebrospinal fluid according to the doctor’s recommendations. In addition, attention should be paid to rest and dietary aspects of the problem, appropriate supplementation of water, reduce the late night, avoid overwork, so as not to aggravate the condition.
