Chronic pain and long-term disability following postdural puncture headache in obstetric patients: a five-year prospective follow-up of a case-control cohort
Authors' conclusion
This five-years follow-up study demonstrates that chronic pain (headache and backache) after an unintended dural puncture is a prolonged condition with substantial functional consequences, challenging its traditional characterization as a transient complication
Study context
- Population
- Obstetric patients after delivery, with or without labor epidural analgesia and postdural puncture headache (PDPH) after unintended dural puncture
- Participants
- 336 patients
- Comparison
- PDPH after unintended dural puncture (with or without epidural blood patch) vs uncomplicated labor epidural or no labor epidural
- No labor epiduraln = 113reference
- Uncomplicated epiduraln = 113reference
- PDPH without epidural blood patchn = 54
- PDPH with epidural blood patchn = 56
- Outcome
- Prevalence of chronic headache and backache (ICHD-based standardized telephone questionnaires)
- Follow-up
- 5 years
Methodological detailsfive-year follow-up
- Five-year follow-up
Main finding
As reported in the abstract
Chronic headache
P < 0.01
Observational data: associations, not effects.
Further findings
| Outcome | PDPH without epidural blood patch | PDPH with epidural blood patch | P value |
|---|---|---|---|
| Chronic backache · 5 yearsPDPH groups vs Control groups | 16.1% | 20.8% | P < 0.01 |
| High disability (Von Korff chronic pain grade) among women with chronic pain · 5 years | 43.8% | 28.6% |
- High disability (Von Korff chronic pain grade) among women with chronic pain: of 16 and 14 women with chronic pain at five years, respectively
Chronic backache · 5 years
- Most women reported persistent rather than resolving symptoms
High disability (Von Korff chronic pain grade) among women with chronic pain · 5 years
- Functional impairment increased over time
