The study prospectively compared the kinetics of post-deflation tissue oxygen recovery between tourniquets with distinct inflation pressures. Forty knee arthroscopy patients were randomized into standard (350 mmHg) or reduced inflation pressure groups. In the latter group, arterial occlusion pressure was calculated according to a formula [(SBP+10)/KTP], where SBP is the systolic blood pressure and KTP is the tissue padding coefficient based on limb circumference; a safety margin of 40-80 mmHg was added based on occlusion pressure. Pulse oximeter probes were applied to operative and nonoperative second toes and connected to a vital signs monitor. After tourniquet inflation, arthroscopy, and cuff deflation, arterial oxygen saturation was measured and recorded by the monitor every minute for 15 minutes. Standard inflation pressure group tourniquet time averaged 50 minutes at 350 mmHg; th.. View More»
