Brief summary
Thromboelastography (TEG) is an in vitro method of measuring whole blood coagulation. It is, however, unknown whether the use of a venous tourniquet during blood sampling effects the results, making interpretation of a patients coagulation unreliable. This trial aims to answer this question.
Interventions
A single blood sample is taken from the antecubital fossa without the use of a venous tourniquet, using a 18g needle and 5 ml syringe. After a 5 minute period a second venous blood sample taken from the contralateral antecubital fossa. A venous tourniquet is use on this occasion for blood sampling. The tourniquet is applied for 30 seconds at 45mmHg prior venous puncture and released immediately after.This is also single venous puncture using a 18g needle and 5 ml syringe. This therefore forms a crossover study.
