Regional analgesia following epidural blood patch.
Anesthesia and Analgesia
|September 11, 1975
Summary
Epidural blood patch (EBP) for post-lumbar puncture headaches does not block the epidural space. This finding supports the continued use of regional anesthesia for future surgical or obstetric procedures after EBP.
Area of Science:
- Anesthesiology
- Neurosurgery
- Obstetrics
Background:
- Severe post-lumbar puncture headaches (cephalgia) are often treated with epidural blood patch (EBP).
- Concerns exist that EBP may impede subsequent regional anesthesia procedures.
Purpose of the Study:
- To evaluate the feasibility of performing regional anesthesia after epidural blood patch procedures.
Main Methods:
- Retrospective analysis of 118 patients who underwent EBP between 1972 and 1974.
- Three patients who later required regional anesthesia (epidural, caudal, or spinal block) for surgery or delivery were analyzed.
Main Results:
- Regional anesthesia was successfully administered in all three patients following EBP.
- The epidural space was easily accessed, and catheter advancement was uncomplicated.
- Block characteristics and local anesthetic efficacy were within normal parameters.
Conclusions:
- Epidural blood patch does not obliterate the epidural space.
- EBP should not be a contraindication for future regional anesthesia in surgical or obstetric settings.
