Remote Ischemic Preconditioning in Head and Neck Cancer Reconstruction - A Randomized Controlled Trial (RIPC-HNC)
The purpose of the trial is to investigate, if remote ischemic preconditioning reduces the risk of complications in patients undergoing resection of head and neck cancer and immediate reconstruction with autologous free tissue transfer.
Remote ischemic preconditioning is a treatment, which is carried out by inducing brief episodes of upper arm occlusion using an inflatable tourniquet.
Blood samples will be taken during the operation and postoperatively to evaluate the effects of remote ischemic preconditioning. These blood samples will be analyzed for clotting properties and markers of inflammation.
Furthermore, effects on the blood supply of the transferred tissue flap will be measured by infrared thermography.
Effects on surgical complication rates will be obtained by clinical follow-up and patient chart review.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Remote ischemic preconditioning
Four 5-minute cycles of upper extremity ischemia, each separated by five minutes of reperfusion.
The treatment will be carried out with a tourniquet inflated to 200 mmHg during general anaesthesia prior to flap ischemia and transfer.
|
|
Sham Comparator: Sham
The tourniquet will be attached to the patient's upper extremity but never inflated.
