Background: Post-dural puncture headache is the most common serious complication resulting from lumbar puncture and epidural or spinal anesthetics. The syndrome is characterized by severe headache that occurs within 48 hours following the puncture, located in the frontal and/or occipital region, worsened in the upright position and refractory to routine analgesia. The syndrome incidence was reported to be approximately 1% with typical obstetric anesthesiology practice which reflects more than 20,000 cases per 2014 in the US. Two possible mechanisms are hypothesized as responsible for this syndrome;cerebrospinal fluid leakage and pneumocephalus. Multiple methods of treatment have been applied with wide-ranging results. Design or Methods: Review article with introduction of a novel treatment option. Results: We postulate that Hyperbaric Oxygen Therapy can be used to treat post-dural puncture headache. The rationale for treatment is dual: enhancement of fibroblast proliferation at the site of dural puncture to facilitate faster closure of the tear and compression of air bubbles in case of pneumocephalus according to Boyle’s law. We also claim that hyperbaric oxygen therapy should be considered a prophylactic treatment, if a dural tear is suspected.展开更多

It is typically performed in patients with characteristic postural headaches due to low intracranial pressure. We report a case of a young female with an implanted Miethke Sensor Reservoir, which was used for continuous intracranial pressure (ICP) monitoring during a two-level epidural blood patch. ICP increased only with thoracic injection, suggesting thoracic EBP may have greater efficacy than lumbar EBP in treating SIH and PDPH when the site of CSF leak is unknown.展开更多

Female, 48 years old, submitted to epidural anesthesia, for surgery, with median puncture, between L2-L3 and inadvertently accessed the subarachnoid space, with clear cerebrospinal fluid. The same puncture was used and the solution with 15 mg hyperbaric bupivacaine and 80 mcg morphine was administered. There was no complication during the entire surgical procedure. On the first postoperative day, she started complaining of headache and nausea, being treated with dipyrone, non-steroidal anti-inflammatory drugs (NSAIDs) and ondansetron. On the third day, she presented two episodes of seizure that ceased with the use of diazepam 10 mg. On the fifth day, the patient presented fever and seizures, which did not stop with medication, requiring sedation, orotracheal intubation and transfer to the intensive care unit. Lumbar puncture was performed for CSF analysis, which was positive for Herpes simplex type I. The patient was extubated, on the second day of hospitalization, maintained with a maintenance dose of phenytoin, sumatriptan, dipyrone, metoclopramide and acyclovir 500 mg, remaining intravenous, without presenting new seizures for 45 days, when she was discharged. After 30 days, he returned for a review consultation without making a complaint.展开更多
