Epidural Blood Patch Performed Immediately After Dural Puncture and Epidural Drug Administration.

ABSTRACT

The epidural blood patch (EBP) is a solution for persistent headaches following an accidental dural puncture. We report three cases where EBP was performed immediately after dural puncture combined with drug administration for lumbago. To the best of our knowledge, no similar cases have been reported in the literature. The patients provided their informed consent, and all standard protocols were followed. At the moment of the dural puncture, all the patients manifested severe headaches, nausea, vomiting, and profuse sweating. A second epidural puncture was performed at a higher intervertebral space, followed by drug administration and 20 mL of autologous blood. All the patients improved gradually, while their headaches vanished after 30-35 minutes. The patients were kept in for monitoring and released the following day with specific instructions and daily phone contact for a week without any complications. Their lumbago symptoms regressed. The possibility of pneumocephalus was excluded because of the patients' symptomatology. The risk of high or total spinal anesthesia due to local anesthetic leakage subarachnoidally was countered with close monitoring of the patients. EBP complications include failure, postdural-puncture headache worsening by an accidental additional dural tear(s), back pain, and infection. All patients were instructed to report any symptoms immediately. EBP executed immediately after dural puncture seems to relieve headache fast and does not appear to impede epidural analgesia.
