What Is A Gallbladder Needle

1. Strict control of contraindications. A fundus examination should be done if intracranial pressure is suspected to increase. Puncture should be contraindicated if there is obvious papilledema or signs of cerebral hernia.

2. Puncture should be contraindiated in patients with shock, failure or endangered state, local skin inflammation, space-occupying lesions in the posterior cranial fossa or brainstem symptoms.

3. After the needle is inserted into the subcutaneous tissue, the needle should be injected slowly, so as not to stab the cauda equina nerve or blood vessels when the force is too strong, so as to produce lower limb pain or make the cerebrospinal fluid mixed with blood to affect the judgment of the result.

4. If the patient has abnormal breathing, pulse, complexion and other symptoms during puncture, the operation should be stopped immediately and treated accordingly.

5. During intrathecal administration, the same amount of cerebrospinal fluid should be released first, and then the drug should be injected.

6. When doing air brain examination, 10 ml of liquid should be slowly discharged first, and then 10 ml of filtered air should be injected, and then the film should be taken when the required amount is reached repeatedly.

7, the release of cerebrospinal fluid speed should not be fast, generally 10-15 drops/minute, normal intracranial pressure patients a release of cerebrospinal fluid is not more than 5ml, to prevent brain herniation.
