Fundus examination must be performed first for those suspected of elevated intracranial pressure, and puncture should be contraindicated for those with obvious papilledema or cerebral hernia. Puncture should be contraindicated in patients in shock, exhaustion or endangered state, with local skin inflammation and space-occupying lesions in the posterior cranial fossa.
2. If the patient has abnormal breathing, pulse, complexion and other symptoms during puncture, the operation should be stopped immediately and treated accordingly.
