Migration measurement of polymorphonuclear neutrophils (PMN) may be a useful diagnostic marker in the treatment of trauma patients. In the development process of a fully automated measuring system, this pilot study tests subcomponents.
For this purpose, the PMN migration of 10 patients with a monotrauma and 6 patients with a polytrauma was measured. Within the monotraumatic group 4 measurement points were defined, for the polytraumatic group 8 measurement points. Each measurement was performed with and without the chemoattractant fMLP. As comparison parameters the CRP, IL-6 and the leukocyte count were collected.
Significant differences in PMN adhesion and median migration (DC50), depending on the severity of the injury, were detected. An influence of fMLP could only be detected in the DC50 of the monotrauma group. In the temporal detection, the PMN migration was not inferior to the measured comparison parameters. In the semi-automated set-up, problems with the fixing solution or the digital image analysis could be eliminated. These insights will be implemented in the construction of the fully automated prototype.
