Postdural puncture tinnitus

Editor—An epidural catheter was sited using an 18G Tuohyneedle at the L4/5 interspace for labour analgesia in a 25-year-oldparturient. The lady made some sudden movements during needleinsertion, but there were no signs of a cerebrospinal fluid(CSF) leak. Unfortunately, she developed a headache of moderateseverity 25 h (day 1)     

Postdural puncture headache: an imaging-guided management protocol

IMPLICATIONS: We propose an imaging-based algorithm for the management of headache caused by the inadvertent puncture of dura that occurs sporadically during epidural analgesia. Its implementation can identify those postdural puncture headache cases that cannot benefit from epidural blood patches, and their unnecessary application can consequently be avoided.     

Postdural puncture headache in obstetrics

Postdural puncture headache is the most common major complication following neuraxial anesthesia; this adverse event is particularly frequent in obstetrics. The headache is usually benign and self-limited but if left untreated can lead to more serious complications that may be life-threatening. Many treatments and prophylactic measures have been suggested, but evidence supporting them is scarce in many cases. After accidental dural puncture the only effective preventive measure is to leave the catheter inside the dura; epidural morphine infusion may also help. Once symptoms begin, treatment is conservative for the first 24 hours. If this approach fails, the most effective intervention continues to be a blood patch, which should not be delayed beyond 24 to 48 hours in order to avoid suffering. If more blood patches are required, other possible causes of headache should be ruled out.     

Postdural puncture symptoms in a child

An 11-year-old boy suffered an inadvertent dural puncture during placement of an epidural catheter for postoperative analgesia. He developed symptoms of mild headache only, but severe and protracted orthostatic nausea and dizziness, which eventually resolved completely following epidural blood patch. His symptoms were atypical and could have been misinterpreted in the context of dural puncture for diagnosis, or for administration of intrathecal chemotherapy. The reported incidence of headache following dural puncture in children is low. It may be that the manifestations are different from those of adults and that the true incidence of symptoms related to leakage of cerebrospinal fluid is higher in children than currently recognised.     

Postdural puncture headache with abdominal pain and diarrhea

Dural puncture or a rent in the dura with prolonged cerebrospinal fluid leakage may cause noninfectious arachnoiditis and may be associated with urinary and fecal incontinence. Visceral dysfunction is common for patients with noninfectious arachnoiditis of the lumbosacral nerve roots after dural puncture. We report a case of postdural puncture headache associated with abdominal pain and diarrhea. An epidural blood patch was performed, and all symptoms resolved after 5 days. After exclusion of organic and psychological disorders, this treatment might be considered for patients who are experiencing abdominal pain and diarrhea after dural puncture.
