Increased skin lactate in complex regional pain syndrome: Evidence for tissue hypoxia?

Abstract
Article abstract To investigate oxygen metabolism in complex regional pain syndrome (CRPS), the authors measured skin lactate via dermal microdialysis performed on patients with CRPS (n = 11) and healthy control subjects (n = 11). In addition, they measured blood lactate. Although venous lactate was unaltered, skin lactate was increased in patients with CRPS (2.95 mmol/L; control subjects 1.74 mmol/L; p < 0.005). These results suggest enhanced anaerobic glycolysis, probably as a result of chronic tissue hypoxia.
