The Effect of Tourniquet Release on Intra-Compartmental Pressure in the Bandaged and Unbandaged Limb

Changes in intra-compartmental pressure in bandaged and unbandaged limbs following 90 minutes of tourniquet-induced ischaemia and subsequent tourniquet release are examined in a primate model. Bandaging raises intra-compartmental pressure. Release of the tourniquet is shown to cause a transient increase in intra-compartmental pressure of less than 30 minutes duration. This is followed by a fall in intra-compartmental pressure for up to three hours. Tourniquet release and the ensuing hyperaemia does not appear to put the limb at risk of developing a compartment syndrome.
