Establishment of a Predictive Model for Post-dural Puncture Headache

Plain-language summary

The goal of this clinical trial is to establish a predictive model for post-dural puncture headache. The main questions it aims to answer are: Changes in intracranial pressure after spinal puncture (or lumbar puncture). When post-dural puncture headache occurs, the optic nerve sheath diameter (ONSD) change When the optic nerve sheath diameter (ONSD) and (or) Intraocular Pressure (IOP) reaches a certain threshold, does proactive treatment reduce the incidence of postoperative headaches? Researchers will measure the optic nerve sheath diameter (ONSD) using ultrasound and ( or ) magnetic resonance imaging (MRI) before and after spinal puncture. Researchers will measure the Intraocular Pressure (IOP) using ICARE before and after spinal puncture. Participants will: Undergo ultrasound and (or) magnetic resonance imaging (MRI) examinations before and after spinal puncture Undergo ICARE examinations before and after spinal puncture
