What is called waist wear?

It is a common clinical diagnosis and treatment operation. It can be used to diagnose various inflammatory diseases of central nervous system, vascular diseases, spinal cord lesions, suspected intracranial mass lesions, unknown neurological diseases, pneumoencephalography, spinal canal angiography, etc. It is also used to discharge fluid (decompression) due to excessive cerebrospinal fluid pressure and to inject drugs to treat central nervous system diseases.

Summary:

Operation method is to bend the patient on the side of bed, both hands embrace the knee, so that lumbar kyphosis, intervertebral space widening. Local routine disinfection, infiltration anesthesia, puncture. Generally, there is resistance when the needle is inserted into 4 ~ 5cm, and the resistance is suddenly reduced. After pulling out the needle core, the cerebrospinal fluid drops out when the needle tail is rotated. Cerebrospinal fluid was removed for different purposes and conditions. Then insert the needle core, pull out the puncture needle, fix with sterilized gauze block, and go to the pillow for 4 ~ 6 hours.

Before lumbar puncture, attention should be paid to the local skin, soft tissue, bone inflammation should not puncture; Patients with obvious intracranial pressure increase and signs of brain hernia can not puncture; Patients in critical condition in shock or on the verge of shock should not puncture; There are symptoms of spinal cord compression disease, spinal cord function has been in the critical state of complete disappearance can not puncture. Prevent headache, herniation and infection after puncture.

Purpose of puncture:

(1) For diagnosis: 1. Take cerebrospinal fluid for testing. 2. Measure brain pressure to understand the level of intracranial pressure. 3. Cerebrospinal fluid dynamics examination. 4. Spinal cord or airbrain angiography.

(2) for treatment: 1. Drainage of bloody cerebrospinal fluid. 2. Remove cerebrospinal fluid to reduce intracranial pressure. 3, intrathecal injection of drugs to treat inflammation or tumor.
