Abstract

|
|
In this survey of the 260 operations that were performed at the Department of Surgery, Chonnam
University Hospital the washings for routine culture were taken from the depth of each wound just
before starting thi closure to identify the problem of correlation of the positive cultures and subsequent
post-operative course. The operative wounds were divided into the clean and potentially dirty categories.
The positive cultures were obtained in 48 cases or 28.7 percent of the 167 clean wounds. The
over-all infection rate of 10 infections in 167 cases was 6.0 percent. The wound infections in the
clean operations were about 4 times more common (12.5% to 3.4%) if the culture were positive
than if negative. Of the organisms recovered, the coagulase-negative staphylococci occurred with the
greatest frequency (in 19 cases or 11.4%), and the post-operative wound infections were usually due
to the coagulase-positive staphylococci.
The organisms were recovered in 45 cases (46.2%) of the 93 potentially dirty wounds. Of the 43
wounds from which the organisms were recovered, 16(37.2%) became infected post-operatively, wheras
only 3 (6.0%) of the 50 wounds sterily by culture became infected. One or more gram-negative
bacilli were predominant findings in the operative culture and wound infections.
The numerous antibiotic drugs were prophylactically administered to the 54.2 percent of the patients
in this study. A higher percentage of the wound infection in the clean operative procedures in patients
given antibiotic drugs than those not receiving antibiotic therapy was found to be misleading in the
evaluation of the prophylactic therapy. Antibiotic agents were used therapeutically for the underlying
diseases rather than as prophylaxis for the wound infection, but the wound considered more likelt yo
become infected were more likely to be treated prophylactically with antibiotics.
