To determine the tissue pressure threshold that triggers cellular anaerobic metabolism and structural injury in resting skeletal muscle subjected to compartment syndrome.
Evaluated experimental ischemic compartment syndrome in dogs using phosphorus-31 nuclear magnetic resonance (31P-NMR) spectroscopy, muscle biopsy, and electron microscopy over an 8-hour pressurization period.
Assessed the interactive effects of systemic mean arterial blood pressure (MABP) and moderate muscle trauma on cellular metabolic thresholds in canine models and a preliminary patient series.
Cellular metabolic derangement correlated more strongly with the perfusion gradient (ΔP, defined as MABP minus compartment pressure) than with absolute tissue pressure alone.
The minimum ΔP required to preserve a normal cellular metabolic state was approximately 30 mmHg in uninjured muscle and 40 mmHg in moderately traumatized muscle.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Translational study demonstrates metabolic failure depends on perfusion pressure gradients rather than absolute tissue pressure in canine and clinical subjects, indicating updated diagnostic criteria.
