Spinal needle size and hearing

Eldor spinal needle versus Pencan spinal needle.

The effect of spinal needle design, size, and penetration angle on dural puncture cerebral spinal fluid loss.

Postdural puncture headache (PDPH) is a debilitating side effect of spinal anesthesia, the result of dural puncture and cerebrospinal fluid (CSF) leakage with an incidence of 3% to 75% in patient populations. Despite numerous in vitro and in viva studies that have identified predictors associated with PDPH, debate continues on the best technique to reduce CSF leak after dural puncture. The purp...

Progressive visual and hearing loss as looming manifestations of spinal meningeal melanocytoma

  Abstract   Meningeal melanocytoma is a rare tumor of nervous system, which originates from leptomeningeal   melanocytes. The locations of melanocytoma in the nervous system are most frequently in the posterior fossa or along the spinal cord, and usually appear as an extra-axial mass. The manifestations of tumor are most often due to its compressing effect on adjacent nervous structures that c...

language learning strategies and vocabulary size of iranian efl learners

learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...

Loss of resistance to saline reduces responses accompanying spinal needle insertion during institution of 'needle-through-needle' combined spinal-epidural analgesia.

Normal saline or air is used to identify loss of resistance during identification of the epidural space for combined spinal-epidural analgesia. Following epidural needle placement using air for loss of resistance, up to 80% of parturients move, grimace, vocalise or experience paraesthesia or dysaesthesia during subsequent dural puncture by a spinal needle. We compared the effects of saline vers...
