BACKGROUND AND OBJECTIVES: The purpose of this study was to determine whether the 26-gauge Atraucan needle shows any benefit on the incidence of postdural puncture headache (PDPH) and back pain as compared with the 27-gauge Quincke needle. METHODS: We investigated 388 patients, 171 men and 217 women, who were receiving spinal anesthesia for subumbilical surgery. We compared spinal anesthesia via the 27-gauge Quincke needle in 202 patients (group Q) and via the 26-gauge Atraucan needle in 186 patients (group A). RESULTS: The incidence of PDPH was 2.97% (6 of 202) in group Q and 2.69% (5 of 186) in group A. The incidence of back pain was 4.95% (10 of 202) in group Q and 5.91% (11 of 186) in group A. There was no statistically significant association of needle type, age, or sex with the incidence of PDPH and back pain. CONCLUSIONS: Both needles are associated with very low incidences of PDPH and back pain, which are not affected by which needle is chosen.
Spinal subdural hematoma, though rare, is an established complication of lumbar puncture. A young man with persistent back and neck pain after a traumatic lumbar puncture for the diagnosis of lymphocytic meningitis is presented. A diagnosis of spinal subdural hematoma at T2 to T8 levels without significant spinal cord compression was confirmed by magnetic resonance imaging. Symptoms resolved after one month of analgesics and muscle relaxants.
UNLABELLED: Persistent cerebrospinal fluid (CSF) leak is an apparently rare complication of dural puncture from spinal or epidural anesthesia. Combined spinal-epidural techniques are increasingly popular but persistent CSF leak has not been reported. We describe three parturients with persistent fluid leak from the insertion site after epidural catheter removal following combined spinal-epidural anesthesia. Uncertainties related to the diagnosis, treatment, and the implications of this complication are discussed, including beta(2)-transferrin immunofixation assay as a diagnostic test for the presence of CSF in this situation. IMPLICATIONS: Combined spinal-epidural block can be complicated by persistent fluid leak from the skin insertion site. Testing for the presence of cerebrospinal fluid may be a useful aid to management.
This report describes a patient with permanent hearing loss after spinal anesthesia. The literature is reviewed, particularly concerning incidence and possible causes. The incidence is surprisingly high and related to the size of the needle. The role of the cochlear aqueduct as a transmitter of a decreased fluid pressure in the subarachnoid space to the perilymph of the labyrinth is discussed.
