  • Ischemia


The purpose of the study is to understand the relevance of tissue oximetry measures of tissue flaps during surgery and during recovery, and to determine if T-Stat is a reliable and early method of detecting compromised flaps.

Study summary:

The tissue saturation of free flaps will be measured before, during, and after surgery and during recovery.
