title: C-reactive protein as a marker of postoperative septic complications.
abstract: OBJECTIVE
  was to answer the question whether or not determination of C-reactive protein in patients after serious abdominal surgeries can be prognostic of septic complications.
  
  
  METHODS
  36 patients who underwent elective surgeries were included in the study. The patients were included either in the group where no postoperative SIRS developed or in the group where postoperative SIRS did occur. In the seven-day period after the surgery, in 26 patients SIRS was found, and in 10 - sepsis was suspected (according to the ACCP/SCCM definitions). In patients who underwent abdominal surgeries blood concentration of C-reactive protein was determined prior to the surgery (measurement '0'), and then on postoperative days 1, 2, 3, 5 and 7.
  
  
  RESULTS
  The test for two variables (C-reactive protein on postoperative days five and seven) showed statistically significant difference, and for one variable (C-reactive protein on day three) - difference at the limit of significance. Thus, it was found that in the postoperative SIRS group the level of C-reactive protein is higher than in the non-SIRS group.
  
  
  CONCLUSIONS
  Serial measurements of C-reactive protein are useful in the first week after surgery, as they can be prognostic of postoperative septic complications. Such complications can be anticipated if CRP on postoperative day 5 is higher than 1/2 of the maximum CRP concentration on day 2 or day 3, or CRP > 150 mg/L as of postoperative day 3. Unfortunately, the severity of the disease cannot be projected based on C-reactive protein level.
