Tourniquet Safety and Effectiveness Clinical Trial
Official title:
A New Technique for Determining Limb Occlusion Pressure
This study evaluates a novel technique for measuring the minimum pressure necessary to achieve a bloodless surgical field, known as a patient's limb occlusion pressure (LOP). Patients will have tourniquets applied to their arms and legs and LOP will be measured using the new technique and a gold standard Doppler ultrasound technique.
Optimal tourniquet safety depends on accurately determining the minimum pressure necessary to achieve a bloodless surgical field, known as a patient's limb occlusion pressure (LOP). However, LOP is not yet routinely measured in all patients due to limitations of current techniques. This study evaluates a novel technique for measuring the LOP through the tourniquet cuff that overcomes many limitations of current LOP measurement techniques. The goal of the study is to determine if the LOP measured by the new technique is statistically or clinically different from the LOP measured by a gold standard Doppler ultrasound technique in adult and pediatric patients ;
