Purpose Of Review:
Post dural puncture headache (PDPH) is a known and relatively common complication which may occur in the setting of patients undergoing lumbar punctures (LP) for diagnostic or therapeutic purposes, and is commonly treated with an epidural blood patch (EBP). There have been few publications regarding the long-term safety of EBP for the treatment of PDPH.
Recent Findings:
The aim of this pilot study was to examine any association of chronic low back pain (LBP) in patients who experienced a PDPH following a LP, and were treated with an EBP. A total of 49 patients were contacted and completed a survey questionnaire via telephone. There was no increased risk of chronic LBP in the dural puncture group receiving EBP (percentage difference 1% [95% CI -25% - 26%], RR: 0.98 [95% CI 0.49 - 1.99]) compared to the dural puncture group not receiving EBP. There were no significant differences in the severity and descriptive qualities of pain between the EBP and non-EBP groups. Both groups had higher prevalence of back pain compared to baseline.
Summary:
Our findings suggest that dural puncture patients undergoing EBP do not experience low back pain with increased frequency compared to dural puncture patients not undergoing EBP. Higher prevalence of LBP compared to baseline and compared to general population was seen in both groups. However, this pilot study is limited by a small sample size and no definitive conclusion can be drawn from this observation. The findings of this study should spur further prospective research into identifying potential associations between LP, EBP and chronic low back pain.

Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
