Paper Abstract

Hyperspectral (HS) imaging has been useful in the monitoring of several medical conditions, which to date have generally involved changes in skin oxygenation in isolated regions of interest such as skin flaps or small burns. Here, by contrast, we present a study in which HSI was used to assess the cutaneous manifestations of significant systemic events. HS imaging of the ventral surface of the lower jaw was used to monitor changes in skin oxygenation during hypovolemic shock induced by pulmonary contusion and hemorrhage in a porcine model, and to monitor the subsequent recovery of oxygenation following resuscitation. Changes are seen both quantitatively, in the level of skin oxygenation as determined by the fitting of reference hemoglobin and deoxyhemoglobin spectra to sample spectra, and qualitatively, in the observed spatial distribution or pattern of oxygenation-related changes in the skin. Linear regression was used to correlate these changes with invasively obtained parameters to include mixed venous oxygen saturation and systemic arterial blood pressure. Historically, the assessment of skin color and mottling has been an important, albeit inexact, component of resuscitation algorithms. Now, it is possible to analyze these variables during shock and resuscitation in an objective manner. The clinical utility of these advances needs to be determined.
