Nerve compression and pain in human volunteers with narrow vs wide tourniquets.

ABSTRACT:

Aim

To assess the clinical effects and the morphological grade of nerve compression.

Methods

In a prospective single-center randomized, open study we assessed the clinical effects and the morphological grade of nerve compression during 20 min of either a silicon ring (group A) or pneumatic tourniquet (group B) placement variantly on the upper non-dominant limb in 14 healthy human volunteers. Before and during compression, the median and radial nerves were visualized in both groups by 3 Tesla MR imaging, using high resolutional (2.5 mm slice thickness) axial T2-weighted sequences.

Results

In group A, Visual analog pain scale was 5.4 ± 2.2 compared to results of group B, 2.9 ± 2.5, showing a significant difference (P = 0.028). FPS levels in group A were 2.6 ± 0.9 compar
