DIAGNOSTIC  LUMBAR  PUNCTURE with a Sprotte^®Atraumatic Needle

	Dramatically decrease incidence of PLPH The use of a Sprotte® atraumatic needle (vs Quincke) in Diagnostic Lumbar Puncture has been shown in controlled studies to reduce the incidence of PLP Headache by a factor of 101,4,5. The design of the atraumatic needle is such that upon withdrawal from the dura a markedly smaller hole is left, (vs Quincke cutting type needle) with a commensurate decrease in CSF loss.
Flow and Pressure Characteristics No compromise in CSF flow rate or the transduction of CSF pressure is experienced with an atraumatic needle3. A study, "Choosing the best needle for diagnostic lumbar puncture" compares pressure and flow characteristics of several brands of atraumatic needle vs the standard Quincke. Selected findings: "We found that Atraumatic needles display flow and pressure characteristics as good and often better than similarly gauged Quincke needles." "The 20-gauge Sprotte Atraumatic needle showed the best characteristics of all needles tested and would appear to be the overall needle of choice for the procedure when both rapid pressure transduction and larger volumes of CSF are required for analysis"			Puncture Technique Initial puncture of skin is made with an introducer needle (held in left hand in illustration). The Sprotte needle is then inserted through the introducer. Use of sterile gloves is unnecessary, since the introducer is provided with grip plate (wings) ensuring reliable insertion and direction without any contact with the needle shaft.
