AbstractTo assess differences in serum interleukin-8 concentrations in resuscitated and nonresuscitated patients after cardiopulmonary resuscitation (CPR), and to compare changes of interleukin-8 levels with hemodynamic variables after restoration of spontaneous circulation, 39 patients with out-of-hospital cardiopulmonary arrest who had undergone CPR were studied. Venous blood samples were taken after CPR and 1 and 2 hours after restoration of spontaneous circulation to measure serum interleukin-8 levels by the enzyme-linked immunosorbent assay method. The median serum interleukin-8 levels after CPR were significantly higher in resuscitated than in nonresuscitated patients (64.9 pg/ml; range 30.2 to 1497 vs 0 pg/ml; range 0 to 31.6 pg/ml; p < 0.001). One and 2 hours after restoration of spontaneous circulation, the median serum interleukin-8 levels were 96.2 pg/ml and 155.4 pg/ml, respectively. Mean values of systolic blood pressure immediately after and 1 and 2 hours after restoration of spontaneous circulation were 117 +/- 9 mm Hg, 130 +/- 11 mm Hg, and 136 +/- 13 mm Hg, respectively. No significant correlations were found between hemodynamic values and serum interleukin-8 levels. In conclusion, successful initial resuscitation was associated with increased serum interleukin-8 concentrations. The interleukin-8 levels remained at high values 2 hours after restoration of spontaneous circulation.
