The 50 original articles included in this qualitative , systematic review revealed that the recommendations " Tourniquet " of the DGAI published in 2016 are mostly still up to date despite an inhomogeneous study situation .
INTRODUCTION The effectiveness of a  tourniquet  in the case of life-threatening hemorrhages of the extremities is well recognized and led to the recommendations on " Tourniquet " of the German Society of Anaesthesiology and Intensive Care ( DGAI ) in 2016 .
The aim of this systematic review was to re-evaluate the current medical literature in relation to the published DGAI recommendations .
Nerve compression and pain in human volunteers with narrow vs wide tourniquets.
AIM To assess the clinical effects and the morphological grade of nerve compression . METHODS In a prospect i ve single-center r and omized , 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 compared to levels in group B 1.6 ± 1 , showing a significant difference ( P = 0.039 ) . Results related to measureable effect on median and radial nerve function were equal in both groups . No undue pressure signs on the skin , redness or nerve damage occurred in either group . There was no significant difference in the diameters of the nerves without and under compression in either group on T2 weighted images . CONCLUSION Based on our results , no differences between narrow and wide tourniquets were identified . Silicon ring tourniquets can be regarded as safe for short time application
