Polymorphonuclear leucocyte migration response in uneventful wound healing following trauma surgery. A contribution to the search for objectifiable criteria in wound healing monitoring.
In a study of the clinical importance of polymorphonuclear granulocytes (PMN) for the monitoring of wound healing we investigated the postsurgical course of nine patients all of whom had undergone trauma surgery and had no wound complications. The "stimulated random PMN locomotion" was evaluated by a new migration filter device which preserves the cells in their genuine priming state, simulating in vivo conditions. The percentage of all activated PMN, expressed by the total migration index (TMI) reflected the highest median immediately after surgery (Zmax = 30.1%) and dropped to the lowest value on day 13 (Zmin = 13.9%). The mean invasion depth (T/2) of the cells along the migration distance into the filter showed only slight variations over time. The neutrophil migration activity (NMA), described by T/2 and TMI, behaved in a similar way to TMI. In studying physiological healing, preliminary results indicate that TMI, which expresses PMN activation, is an efficient tool in the postoperative monitoring of patients, and might in the future serve as a basis for an early warning system for wound healing complications.
