Filter by:Near infrared spectroscopy (NIRS) provides a non-invasive means of continuously monitoring tissue oxygenation, which may be useful for diagnosis of acute compartment syndrome (ACS). Placement of these sensor pads on the surface of the skin must be such that light penetrates the intended compartment without inadvertently obtaining measurements of an adjacent compartment. The objective of this study is to examine whether the NIRS measurements of each compartment truly represent the tissue perfusion of the intended compartment, as indicated by the predictable decrease in muscle oxygenation of a given compartment in response to muscle fatigue. The investigators hypothesize that the tissue oxygenation values of the stimulated compartment will significantly decrease following muscle stimulation, indicating that the intended muscle compartment was successfully isolated. Additionally, the investigators hypothesize that NIRS values of unstimulated muscle compartments will not change from baseline.
This is a prospective observational study to determine the reliability and accuracy of Near Infrared Spectroscopy (NIRS) to detect oxygen flow in the extremities of injured and non-injured soldiers over time. This technology may be useful in the detection of acute compartment syndrome. We hypothesize that: - NIRS values will be well-correlated with intracompartmental pressure measurements - NIRS values will be significantly different between non-injured and injured extremities, and injured extremities treated with fasciotomy for acute compartment syndrome. - NIRS values of the upper extremity and feet will correlate to values from normal legs in critical control patients and patients with unilateral sever lower extremity injuries.
The purpose of this study is to define the reliability and accuracy of Near Infrared Spectroscopy (NIRS) in the detection of intra-compartmental tissue perfusion in injured and noninjured extremities over time. The investigators hypothesize that this technology, combined with vital signs, intracompartmental pressures and clinical examinations, will be useful in diagnosing acute compartment syndrome (ACS), monitoring patients at risk for ACS, and evaluating the adequacy of fasciotomy in patients treated for ACS.
