Types of Lumbar Puncture Needles Two types of lumbar puncture needles are available—the atraumatic (Sprotte or Pajunk) needle and the standard (Quincke) needle. Either the 22-gauge or 20-gauge atraumatic needle, with or without an introducer, can be used for diagnostic lumbar puncture. Use of an atraumatic needle compared with a standard needle and use of a 26-gauge standard needle compared with a 22-gauge standard needle have been shown to be associated with reduced risk of headache after lumbar puncture.29, 30 Source: Lumbar Puncture, The Rational Clinical Examination: Evidence-Based Clinical Diagnosis Citation: Simel DL, Rennie D.
