About this study
This study aims to evaluate plasma-rich fibrin epidural injection by Racz catheter and epidural blood patch in Post dural puncture headache.
Read the detailed description
Post-dural puncture headache (PDPH) is also known as post-lumbar puncture (LP). PDPH is a major complication of neuraxial anesthesia that can occur following spinal anesthesia and with inadvertent dural puncture during epidural anesthesia.
Traditional management strategies include conservative measures such as oral analgesia, bed rest, oral or intravenous hydration, oral or intravenous caffeine, and administration of epidural crystalloid before catheter removal, but in refractory cases, more invasive techniques may be necessary. An epidural blood patch (EBP) has been the most favorable treatment for PDPH after an accidental dural puncture.
One innovative approach is the use of plasma-rich fibrin (PRF) derived from autologous whole blood, which contains and releases several different growth factors and cytokines to stimulate the healing of bone and soft tissue via degranulation. This approach has recently gained popularity in pain management. Another is the Racz catheter, a thin and flexible catheter used for targeted delivery of therapeutic agents.

What is being measured
The primary outcome is the main question the study is designed to answer.
Success rate of the procedures
The success rate of techniques for the treatment of headaches and associated symptoms on a 4-point rating scale (0 = none, 1 = slight, 2 = marked, 3 = complete relief) will be recorded.
Measured: 24 hours postoperatively
Secondary outcomes (4)
Degree of pain
The degree of pain will be assessed using the Numeric Rating Scale (NRS). NRS (0 represents "no pain" while 10 represents "the worst pain imaginable"). NRS will be assessed at (0, 6, 12, 24, 48) h, 3, 4, 5, 6, 7, 8 days postoperatively.
Measured: 8 days postoperatively
Length of bed rest
Length of bed rest after techniques and the efficacy of techniques for the treatment of headaches and associated symptoms on a 4-point rating scale (0 = none, 1 = slight, 2 = marked, 3 = complete relief) will be recorded.
Measured: 8 days postoperatively
Change in optic nerve sheath diameter (ONSD)
Optic nerve sheath diameter (ONSD) will be measured before and after 6 hours of the procedure.
Measured: 6 hours the procedure
Incidence of complications
Incidence of complications that may occur during the technique such as (bending of the tip of the needle, shearing of the catheter, misplacement of the catheter, blocking of the catheter, blood aspiration and bleeding in the epidural space, hypotension, migration of the catheter, paresthesia, headache and infection) will be recorded.
Measured: 8 days postoperatively
