  17. 18. EBP <ul><li>C omplication rate is rare </li></ul><ul><li>~ 35% backache </li></ul><ul><li>S uccess rate is ~ 94% (70-98%) </li></ul><ul><ul><li>90% initial relief </li></ul></ul><ul><ul><li>61-75% persistent relief </li></ul></ul><ul><li>Repeat EBP has a similar success rate </li></ul><ul><li>R everse compl i cations of dural pu n cture </li></ul>
  18. 19. Treatment <ul><li>I t is recommended not to delay EBP more than 24 h after the diagnosis of severe PDPH </li></ul>
  19. 20. EBP <ul><li>Mostly performed in the recovery room </li></ul><ul><li>Sometimes in the labour ward </li></ul><ul><li>Rarely in the patient’s room </li></ul><ul><li>Generally performed with the help of a resident or a staff member </li></ul><ul><li>Rarely performed by one person </li></ul>Gunaydin et al. Acta Anaesthesiol Belg 2008
  20. 21. EBP <ul><li>Intravenous access before EBP (69%) </li></ul><ul><li>ECG (58%) </li></ul><ul><li>Blood pressure (65%) and </li></ul><ul><li>Pulse oxymeter (63%) were performed by the majority of the responders </li></ul>Gunaydin et al. Acta Anaesthesiol Belg 2008
  21. 22. Advices at discharge after a successfull EBP <ul><li>Discharge </li></ul><ul><ul><li>After EBP 1 (4%), 2 (15%) or 3-6 hours (44%) </li></ul></ul><ul><li>Follow-up </li></ul><ul><ul><li>Before full mobilization 2 (47%) or 4 hours (23%) of bed rest </li></ul></ul><ul><ul><li>Increase fluid intake </li></ul></ul><ul><ul><li>Keep intervention side clean </li></ul></ul><ul><ul><li>Contact whenever headache reoccurs and report fever, weakness or numbness </li></ul></ul>Gunaydin et al.

Acta Anaesthesiol Belg 2008
  23. 24. Conclusion <ul><li>According to the present survey, re-siting epidural catheter at a different intervertebral space or using epidural catheter as an intrathecal catheter was preferred for the prevention of PDPH in case of recognized accidental dural puncture </li></ul><ul><li>N on - i n vasive methods consisting of encouragement of fluid intake and drugs were routinely used for the treatment of PDPH </li></ul>
  24. 25. Conclusion <ul><li>Although these results showed the current practice of this small sample, in order to follow the change in these strategies and to catch almost a standard approach for the prevention and management of PDPH , further surveys including most of the centers are required. </li></ul>
