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 .
An evaluation of combat application tourniquets on training military personnel: changes in application times and success rates in three successive phases
Introduction Haemorrhage from the injured extremity is a significant cause of preventable death in military setting s. This study evaluated the effect of training on the efficacy of the combat application tourniquet ( CAT ) and to define st and ards for military personnel . Method Participants from a training tank battalion were r and omised . Data collected included age , body mass index , mean arterial pressure , h and dominance , femoral artery diameter and skin thickness . The study involved  tourniquet application times ( AT ) and application success rates in basic , after-training and eyes-closed phases . Doppler ultrasound was used to identify the presence or absence of popliteal , radial and ulnar artery pulses . Results A total of 102 trainees participated . In the after-training phase , the left and right upper extremity ATs were 35±13.1 s , and 34.8±13.5 s and the right and left lower extremity ATs were 20.6±6.0 s and 20.5±5.5 s , respectively . The overall tourniquet success rates in three successive study phases were 69.6 % , 82.4 % and 91.2 % , respectively . A negative significant relationship was found between extremity circumference and tourniquet success . Discussion The results show that the efficacy of CAT application  increases with training . Further studies are required to investigate the reasons underlying application failures . This single group prospect i ve r and omised study involves level of evidence 4
