@entity6081 is the most frequent complication of surgical treatment. The occurrence of @entity281 depends on many factors, but the most important is bacterial contamination of wound according to the site of operation. The aim of this study was to establish wound @entity281 rate and to determine the relationship between site of operation, wound contamination and the other surgery related factors and @entity6081 risk. The material was 1527 surgically treated @entity1 in the 3rd Surgical Department of the Collegium Medicum of the Jagiellonian University during one year. From the study population were excluded 66 @entity1 with wounds of the head and 7 @entity1 who died within three days after surgery without wound @entity281 signs. The healing of each wound was observed during the @entity1 's hospitalisation and 30 days after discharge from hospital, and in orthopedic @entity1 6 months after discharge. The total number of 132 infected wounds was identified. The population of 1352 wounds healed without any complications was a control group. Data were recorded in a Wound Infection Register Card and were collected in the computer database. The data were statistically analysed. Relations between single factor and @entity6081 were evaluated using chi2 statistics and in the small group Fisher's exact probability test. Odds ratios and corresponding 95% confidence intervals were computed for all variables. The overall wound @entity281 rate was 8.9%. The significant factors (p < 0.05) were @entity344 , reoperation, intraoperative X-ray examination, haematoma of the wound after operation, skeletal traction prior to surgery and implantation of prosthetic material in clean wounds. CONCLUSIONS: 1. Wound contamination, site of operation (GI tract), open drainage, reoperation, intraoperative X-ray examination and postoperative haematoma of the wound are statistically significant risk factors which influence @entity6081 rate. 2. @entity86 of wound is the most important local risk factor of wound @entity281 after surgery.
