What Researchers Did
Researchers evaluated the ability of transcutaneous oxygen pressure measurements, particularly in hyperbaric oxygen conditions, to predict the outcome of limb injuries in 23 patients with major vascular trauma.
What They Found
In normal air, transcutaneous oxygen pressure (PTCO2) measurements did not predict limb amputation in patients with major vascular trauma. However, in hyperbaric oxygen (2.5 ATA), the PTCO2 ratio between injured and uninjured limbs was significantly higher in patients whose surgery succeeded (81.2 +/- 26.0) compared to those requiring amputation (15.2 +/- 13.1; p < 0.01).
Canadian Relevance
This study was conducted outside of Canada and does not have a direct Canadian connection.
Study Limitations
A limitation of this study is its relatively small sample size of 23 patients, which may limit the generalizability of the findings.
