Summary

What Researchers Did

Researchers measured transcutaneous oxygen (pO2) and carbon dioxide (pCO2) levels on human forearm skin after injecting histamine, PGE2, or saline.

What They Found

Steady-state transcutaneous pO2/pCO2 levels were unchanged by histamine or PGE2. However, dynamic tests revealed that the skin's metabolic rate was significantly reduced at all injection sites, with the greatest reduction observed at the histamine site. This reduction in oxygen consumption is attributed to increased diffusional distances caused by excess interstitial fluid separating tissue cells.

Canadian Relevance

Study Limitations

The abstract does not explicitly detail specific study limitations, but the findings are based on acute responses in healthy forearm skin.
