While intracompartmental pressure monitoring is a widely used diagnostic tool to measure intracompartmental pressures in the setting of compartment syndrome, its invasive nature has prompted the development of noninvasive techniques, such as near-infrared spectrometry. We prospectively assessed the association between tissue oxygen saturation measured by near-infrared spectrometry and compartment pressure measured by intracompartmental pressure monitoring in a cohort of patients with compartment syndrome of the lower extremity. We hypothesized that tissue oxygen saturation measured by near-infrared spectrometry would negatively correlate with intracompartmental pressures. Tissue oxygen saturation was determined for all 4 compartments of the lower extremity in 7 patients using near-infrared spectrometry. All patients subsequently underwent lower-extremity fasciotomies. Mechanism of injury, compartment pressures, blood pressure, near-infrared spectrometry measurement of tissue oxygen saturation, and characteristics of the muscle at the time of fasciotomy were recorded. The strength of the correlations between tissue oxygen saturation and absolute and relative compartment pressures was estimated based on mixed linear (growth) models with repeated observations nested within patients. Our analyses demonstrated no significant relationship between tissue oxygen saturation measured by near-infrared spectrometry and the absolute or relative compartment pressures. This suggests that compartment tissue oxygen saturation measurements by near-infrared spectrometry do not correlate with the diagnosis of compartment syndrome, and that near-infrared spectrometry would not serve as a reliable diagnostic tool.
