Unintentional dural puncture with an epidural needle complicates approximately 1% of epidural anaesthetics and causes an acute headache in 60–80% of these patients.

Several retrospective studies suggest an increased risk of chronic headache.

We assessed the relationship between unintentional dural puncture and chronic disabling headache, defined as one or more functionally limiting headaches within a 2-week interval ending 2, 6, and 12 months postpartum.

In this prospective observational study, parturients who experienced unintentional dural puncture were matched 1:4 with control patients.

Patients completed questionnaires regarding characteristics of headache and back pain pre-pregnancy, during pregnancy, immediately postpartum, and at 2, 6, and 12 months postpartum.
