Early diagnosis of postoperative infection: assessment of whole blood chemiluminescence.
Whole blood chemiluminescence (CL), which allows for the evaluation of both the oxygen radical release by phagocytes and the serum opsonin activity using very small amounts of blood, is considered to be a useful means of assessing the host defense against infection. We measured the whole blood chemiluminescence in 59 patients before and after open surgery (surgery by a laparotomy) for gastrointestinal disease. Early postoperative infection was detected in 12 (20.3%) of the 59 patients. These 12 patients all had significantly higher white blood cell counts compared with the noninfected patients on the third and subsequent days after surgery (P < 0.01). The peak CL in the early postoperative infected group was also significantly higher than that in the noninfected group on the day of surgery (P < 0.0001), 1 day after surgery (P < 0.0001), and 3 days after surgery (P < 0.01). Whole blood CL may therefore be a useful modality for the early detection of postoperative infection in the future.
