the Influence of Remote Ischemic Preconditioning on Inflammation During Human Endotoxemia

"A blood-pressure cuff with handheld rubber inflation balloon and manometer is placed on the non-dominant arm of the subject. The cuff will be placed proximally from the elbow with the most proximal part of the cuff placed in the armpit. The cuff will be inflated to 250 mmHg after which a 5 minute countdown is started. After 5 minutes the pressure is released and the 5 minute countdown for reperfusion is started. This concludes one cycle out of a total of four.~1 RIPC-dose consists of 4 cycles of 5 minute ischemia followed by 5 minute reperfusion as described above.~Multiple-dose RIPC consists of a daily dose of 1 RIPC as described above for 7 consecutive days."

To achieve a controlled inflammatory state, 30 subjects (multiple-dose RIPC group \[n=10\], single-dose RIPC group \[n=10\] and control group \[n=10\]) will receive LPS intravenously. The LPS at a dose of 2 ng/kg iv will be injected in 1 minute.
