Historically, surgical wounds are divided into clean, clean-contaminated, and contaminated. In overall, surgical wound infections are now the second most common hospital-acquired infections accounting for at least 17 percent of nosocomial infections. The risk of developing a wound infection is estimated 0.8, 1.3 and 10.2 percent for clean, clean contaminated and contaminated wounds respectively, when antibiotic prophylaxis administered. To establish a baseline of a hospital infection problem and the wound infection rate, it is recommended to conduct a surveillance of clean (Class 1) surgical procedures.
Having considered this fact, the present study was conducted in order to determine the infection rate of clean surgical procedures, to study the relationship of wound infections with factors such as age, duration of operation and antibiotic prophylaxis. A total of 845 clean surgical wound cases were screened for infection during a period of nine months, January-December, 2000.
The infection rate of post-operative clean wound was found to be 4.9% and it was more common in procedures lasted over one hour. The most common organism isolated was staphylococcus epidemidis (%73 of cases), the second was staphylococcus aureus (% 17), and the third was enterobacter aerogenes (%4.9). The in vitro sensitivity of S. epidermidis and S. aureus to the common anti-microbial drugs showed that they were resistant to penicillin and ampicillin.
This study calls for the need of a more organized and effective infection control program that includes an active infection surveillance system and the presence of vigorous control measures designed to eliminate recognized hazards.
