Local cellular inflammation as a result of elective standardized vascular surgery.
During surgery, incision of the skin under aseptic conditions is performed. Despite the absence of noxious agents, an inflammatory response may be induced. We studied the local inflammatory response in human skin as a result of surgical intervention, under aseptic conditions. Elective standardized vascular surgery served as a model. A series of skin biopsies was taken from the wound edge at different time points after first incision. Biopsies, directly taken at first incision were considered to represent normal skin. Additional biopsies were taken at 30 min after the start of surgery and just before closure of the wound, maximally 270 min after surgery. Kinetics of recruitment of cells, expression of adhesion molecules and the presence of pro-inflammatory cytokines was studied. Granulocytes were observed at first at 30 min after incision of the skin and their number increased in time. This granulocyte infiltration is paralleled by E-selectin expression on endothelial cells, which also was observed at first at 30 min after surgery with a further increase in number in time. Incision of the skin did not change P-selectin, ICAM-1, VCAM-1, TNFalpha, IL1alpha, IL1beta, IL6 and IL8 expression. These results show that incision of the skin under aseptic conditions during elective standardized vascular surgery induces local nonspecific cellular inflammation.
