Animal Model: Tourniquet Assisted CPR

A study evaluated the effectiveness of tourniquet assisted CPR in a porcine model (Figure). Thumper Cardiopulmonary Resuscitation was performed subsequent to inducing cardiac arrest in 10 animals; a control group of 5 underwent an unassisted CPR, while an Esmarch exsanguination tourniquet was placed on the limbs of 5 additional animals during resuscitation. Results show that […]

Comparison of HemaShock & PASG/MAST

We developed the HemaShock®, an Auto-Transfusion tourniquet, which is an elastic torus with a long sleeve wrapped around it that, when applied to a limb, squeezes the blood away from the limb into the central circulation and blocks the re-entry of blood into it. Below is an outline of the differences and similarities between our new […]

Tourniquet Ischaemia – Clinical and Biochemical Observations

Ann Chir Gynaecol. 1978;67(6):210-3. SantavirtaS, KausteA, RindellK The duration of tourniquet ischaemia was recorded in 1000 consecutive operations on extremities under a bloodless field, the average ischaemia time was 74.11 +/-29.52 minutes. The duration of tourniquet ischaemia in meniscectomies was 58.47 +/- 15.91 minutes, in osteosynthesis of malleolar fractures 88.46 +/- 23.33 minutes and in operations […]
