[Predicting purulent complications in surgery by determining antibody affinity].

Blood serum of 153 operated patients was studied, 133 of them had uncomplicated postoperative period, 20 patients had postoperative infectious complications. Control group consisted of 23 healthy donors. Coefficient of antibodies affinity was deduced mathematically. If this coefficient didn't exceed 15%, probability of complications development was 90%; if this coefficient ranged from 15 to 30%, probability of complications was 50%; if coefficient exceeded 30%, complications in postoperative period were the least probable. This method can be used for humoral immunity evaluation in surgical patients, bearing in mind its prognostic and diagnostic significance.
