Comparison of sprotte and Quincke needles with respect to spinal fluid leakage using artificial spinal cord.

Purpose: This research investigated whether the Sprotte needle causes less leakage of CSF than the Quincke needle in the artificial spinal cord.

Methods: The changes in intradural pressure, extradural pressure, and leaked volume of CSF were evaluated following puncture with Sprotte and Quincke needles in the artificial spinal cord.

Results: The decrease in intradural pressure was 9.7±1.8 mm HO with the Sprotte needle and 20.5±2.7 mm HO with the Quincke needle (P<0.05). The volume of leakage of artificial CSF was 2.0±0.3 ml with the Sprotte needle and 3.3 ±0.3 ml with the Quincke needle (P<0.01). The extradural pressure increase was 166.1±8.2 mm HO with the Sprotte needle and 186.8±13.2 mm HO with the Quincke needle (P<0.05).

Conclusion: The Sprotte needle produces less CSF leakage than the Quincke needle.
