Chemiluminescence response of whole blood in patients undergoing urological operations.
Polymorphonuclear leukocytes (PMNs) are one of the most important components of the defence mechanisms against bacterial infection. The functions of PMNs are believed to be impaired in patients during the perioperative period. Bactericidal function of PMNs was investigated together with the luminol-dependent chemiluminescence (CL) reaction of whole blood in 23 patients, 12 undergoing open surgery and 11 undergoing endoscopic surgery. Blood samples were collected one day before surgery (day -1) and 2 hours (day 0), 24 hours (day 1) and 7 days (day 7) after surgery. Counts of whole white blood cells (WBCs), PMNs and lymphocytes were not different between the two surgery groups. CL responses in the open surgery group were increased on days 0, 1 and 7. In the endoscopic surgery group, CL response was increased on day 1, but not on day 0 or day 7. These results suggest that the PMN function during the perioperative period was not impaired, but increased just after surgery, mainly due to an increasing number of WBC caused by the surgical intervention.
