NCT03474952

Brief Summary

Remote ischemic preconditioning (RIPC) has been revealed organ-protective effect in many previous clinical settings including coronary intervention or cardiovascular surgery. However its protective role during free flap reconstructive surgery in head and neck cancer patients has not yet been elucidated. The purpose of the current study is to evaluate the effect of RIPC on tissue oxygen saturation and skin temperature of the flap, as well as its organ-protective effect using Langendorff isolated heart ischemia-reperfusion model.

Study Arms (2)

Remote ischemic preconditioning (RIPC)

EXPERIMENTAL

Intervention is remote ischemic preconditioning (RIPC) consists of 4 cycles of 5-min ischemia (using pneumatic cuff pressure of 200 mmHg) and subsequent 5-min reperfusion applied to upper arm.

Procedure: remote ischemic preconditioning (RIPC)

Control (Sham-RIPC)

SHAM COMPARATOR

Intervention is Sham-RIPC (ischemia pressure \< 10 mmHg) applied to upper arm.

Procedure: sham-RIPC
