Introduction:Post-dural puncture headache (PDPH) is the most common complication of intraspinal nerve block in gravida. PDPH may be accompanied by neck stiffness, tinnitus, hearing loss, photophobia or nausea.Patient concerns:A 33-year-old woman whose dura was accidentally punctured during labor analgesia complained of severe headache, dizziness, and nasal congestion; these symptoms aggravated when she looked up, and her sense of smell was normal 8 hours after catheter removal.Diagnoses:Based on the patient’s complaints and clinical appearance, diagnosis of PDPH was considered.Interventions:Nasal congestion disappeared with headache and dizziness after epidural injections of saline. The puerpera received saline injections 4 times; after treatment, she was discharged from the hospital when the symptoms did not limit her daily movement.Outcomes:The symptoms disappeared completely on the seventh day of telephone follow-up visit. The mechanism of her nasal obstruction is not very clear.Conclusion:We believe it is caused by the pulling of the intracranial nerve as the brain tissue sinks and shifts due to the decrease in intracranial pressure.
