Precautions for lumbar puncture

1. There are some contraindications to lumbar puncture, in which case lumbar puncture cannot be performed. In addition, if the patient's intracranial blood pressure is elevated, a fundus examination needs to be done first, and the follow-up depends on the situation. Patients with papilledema and signs of brain herniation are also not allowed to perform puncture. Similarly, puncture should not be performed for patients in shock, exhaustion, endangered state, patients with skin inflammation, and space-occupying lesions in the posterior cranial fossa.

2. In the process of puncture, once the patient's breathing, pulse, and complexion are abnormal, all ongoing operations should be stopped immediately, and corresponding treatment should be made promptly.
