VELAZQUEZ MENDOZA, J. Dolores et al. Prevalence of surgical site infection in patients with abdominal surgery. Cir. gen [online]. 2011, vol.33, n.1, pp.32-37. ISSN 1405-0099.

Objective: To know the prevalence of surgical site infections in patients subjected to either elective or emergence abdominal surgery at a General Surgery service in a second level health care center. Setting: PEMEX Regional Hospital at Salamanca . Second level health care center. Design: Prospective, transversal, descriptive and observational study. Statistical analysis: Central tendency measures. Patients and methods: We included those patients subjected to abdominal surgery at the General Surgery service, between the month of July and December 2007. We analyzed those that presented infection of the surgical site. We excluded those patients that were not operated in this hospital. Analyzed variables were age, gender, type of surgery, associated pathologies, and surgical complications. Results: In the study period, we analyzed a total of 105 surgical procedures. There were 55 women (52.4%) and 50 men (47.61%), average age of 43 ± 26.5 years with a range of 3 to 83 years. Elective surgery was done in 75 patients, and 30 patients corresponded to emergency surgery. Performed surgeries were, in order of frequency, cholecystectomy, appendicectomy, inguinal plasties with mesh placement, placement of Tenckhoff catheter, exploratory laparotomies, umbilical plasties, and fundoplications. Of the total of procedures performed, six patients (5.7%) coursed with infection of the surgical site. Conclusion: Prevalence of surgical wound infection in this study is similar to that reported by other authors. It is important to count upon prevention and treatment protocols for infections of surgical wounds. Besides, the characteristic microbiology of the institution and of each service has to be known for an adequate and optimal management of antibiotics.
