Incidencia de la infección de la herida quirúrgica en cirugía colorrectal electiva y su relación con factores perioperatorios

Abstract

IntroductionSurgical wound infection in colorectal surgery has incidence rate of up to 26%. Peri-operative factors and those of the patients themselves play a part in these infections. The correct administration of the antibiotic, a normal temperature, and hyperoxygenation are a commonly applied triad. The primary aim of the study was to evaluate the incidence of surgical wound infection in patients subjective to colorectal surgery where a surgical infection prevention protocol was applied. The second objective was the relationship between surgical infection and peri-operative factors. Material and methodsAn observational study was conducted on 100 patients who had undergone elective colorectal surgery. Demographic data and related surgical and post-surgical data were recorded. A surgical wound infection was defined using the criteria of Disease Control and Prevention Hospital Infection Centres ResultsThe median age of the patients was 68 years (range 25-88), 65% were male, and 59% were ASA 3-4. There was more than 80% compliance to the protocol in its different sections. There was laparoscopic access in 31% of the cases. The incidence of superficial and deep surgical wound infection was 25%. The patients with an infection had a higher prevalence of diabetes (48% vs 24%), transfusion (56% vs 28%), paralytic ileum (48% vs 18.7%), and intra-abdominal abscess (16% vs 3%). The multivariate analysis associated, preoperative haemoglobin and blood glucose, and the duration of the surgery, with incisional infection. ConclusionsThe prevention protocol did not have an impact on the incidence of surgical wound infection.
