[Transcutaneous po2 measurement in follow-up of severe soft tissue injuries of open fractures].
The transcutaneous assessment of tissue oxygenation has become an useful method in evaluating microcirculatory disorders in different diseases. In this clinical experimental pilot study the impact of compound fractures on tissue oxygenation was examined. Using a special probe placed directly into the muscle, tissue oxygenation was measured at the site of tissue injury as well as at one non-injured site within the same fractured extremity. Furthermore, also one non-injured extremity was measured as a control. At the injured site tissue oxygenation was significantly increased during the first 4 days after trauma as compared to the non-injured extremity (40.7 +/- 1.8 mmHg vs. 23.5 +/- 4.1 mmHg). At the same time the non-injured site of the fractured extremity appeared to be significantly less oxygenated as compared to the noninjured extremity (13.2 +/- 2.3 mmHg vs. 23.5 +/- 4.1 mmHg). After day 4 until the end of the study (day 10) a complete return to normal values was noted at both sites. In conclusion it is most likely that due to a change of microcirculation within the fractured extremity the injured site is temporarily oversaturated by oxygen combined with lacking oxygenation at the non-injured site. As the microcirculatory status may be important in making decision in trauma surgery (e.g. whether or not to amputate) the method of transcutaneous oxygen measurement is a practical and useful method in trauma care.
