[6/1/2009] The results of a clinical study in the field of plastic and reconstructive surgery where the ViOptix T.Ox Tissue Oximeter was used were recently published in a peer-reviewed journal.
“A New Diagnostic Algorithm for Early Prediction of Vascular Compromise in 208 Microsurgical Flaps Using Tissue Oxygen Saturation Measurements”, Alex Keller, MD, Annals of Plastic Surgery: May 2009, Volume 62, Issue 5, pp. 538-543.
Criteria studied in various combinations were the absolute value of tissue oxygen saturation (StO2),
the amount of its change (DStO2) and
the rate of its change (DStO2/Dt). 208 flaps were monitored.
The new algorithm predicted
post-op complications within one hour of the onset of the occlusive event. Five
patients exhibited complications predicted by the tissue oximeter before clinical
signs were evident.
The investigator concluded that T.Ox facilitates detection of vascular complications before they are clinically apparent; that salvaged flaps should have less fat necrosis because ischemic time can be shortened and no flap being monitored was lost.
