[Bacteriological study of surgical infected wounds in elective surgery. Bacteriology of surgical wound infection].
OBJECTIVE
To identify the frequency and type of microorganisms isolated from infected surgical wounds at the Instituto Nacional de Perinatología, and identify the association among the microorganisms isolated and the outcome of the infected patients.


METHODS
Observational, descriptive and cross-sectional study carried out between January 1999 and January 2001. Postoperative patients of an obstetric or gynecologic procedure, complicated with a surgical wound infection and with a culture and smear of the wound, were included.


RESULTS
During the study period 41 surgical wound infections were identified. The general incidence of surgical infections was 3.9 infections per 1,000 surgical procedures. The incidence of infections after abdominal hysterectomy was 12.4 per 1,000, after vaginal hysterectomy 6.5 per 1,000, postcesarean section 5.3 per 1,000 and after episiotomy 1 per 1,000 procedures. The comparison among bacterial isolates in 1988 with 1999-2000 period showed a high frequency of gram negative bacteria isolation in the second period.


CONCLUSIONS
In this study the incidence of surgical infections was less than the incidence reported in the medical literature, but the type of bacteria isolated was similar to other studies.
