Observational Study
Chronic disabling postpartum headache after unintentional dural puncture during epidural anaesthesia: a prospective cohort study.
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. ⋯ Our prospective trial confirms retrospective studies that chronic headache is more prevalent among women who experienced unintentional dural puncture compared with controls who received uncomplicated neuraxial anaesthesia. This finding has implications for the. patient consent process and recommendations for long-term follow-up of patients who experience unintentional dural puncture.
