[A study on distribution of surgical site infections in risk hospital wards in Bulgaria (2000-2004)].

Surgical site infections are some of the most widely distributed nosocomial infections. The study covers the period 2000-2004. It follows the frequency of surgical site infections in various in profile hazardous hospital wards: surgery wards (general surgery, cardiac surgery, pediatric surgery, neurosurgery, orthopaedic surgery, burn/trauma wards), wards of intensive therapy and reanimation, gynaecological and urological wards. The study gives the etiological characteristics of the surgical site infections during the studied period. The most frequent etiological agents are Staphylococcus spp. (S. aureus and coagulase-negative Staphylococci) and from the group of Gram-negative bacteria--E.coli, Pseudomonas spp. The enterococcus spp. is of great significance in the gynaecological and urological wards.
