Hello,
Does anybody have any sources that address the concept of long tourniquet time affecting venous lactate levels? I've done some initial searches and browsed the email archive and have found a lot about venous vs. arterial comparisons, and I've found one study of tourniquet time in healthy volunteers, but I haven't found much in septic patients specifically. Our protocols routinely use venous lactate and we instruct people to take any elevation seriously regardless of tourniquet time, but it would be useful to have a citation to back this up. Thanks very much, Joe Joseph Clement, MS, RN, CCNS Clinical Nurse Specialist San Francisco General Hospital ph: 415206-6174 pg: 415 327-0220
