May support lower tourniquet pressures in average patients; cross-sectional data leaves open need for randomized validation.
What is the minimal pneumatic tourniquet pressure necessary to produce a bloodless field during limb surgery?
Minimal tourniquet pressures of 200 mm Hg for upper limbs and 250 mm Hg for lower limbs are adequate for average-sized normotensive patients, potentially reducing complications from excessive pressure.
Alan J. Thurston (1985) studied this question.
