[Incidence of surgical wound infection in elective colorectal surgery and its relationship with preoperative factors]. / Incidencia de la infección de la herida quirúrgica en cirugía colorrectal electiva y su relación con factores perioperatorios.

INTRODUCTION: Surgical 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 METHODS: An 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. RESULTS: The 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. CONCLUSIONS: The prevention protocol did not have an impact on the incidence of surgical wound infection.

Introducción La infección de la herida quirúrgica en cirugía colorrectal presenta una incidencia de hasta el 26%. En su desarrollo intervienen factores del propio enfermo y perioperatorios. La administración correcta del antibiótico, la normotermia y la hiperoxigenación representan una tríada de común aplicación. El objetivo fue valorar la incidencia de infección de la herida quirúrgica en pacientes sometidos a cirugía colorrectal a los que se aplicó un protocolo preventivo de infección quirúrgica; como segundo objetivo se relacionó la infección quirúrgica con factores perioperatorios. Material y métodos Se realizó un estudio observacional incluyendo a 100 pacientes de cirugía colorrectal electiva. Se recogieron datos demográficos, datos relacionados con el intraoperatorio y el postoperatorio. Se definió la infección de la herida quirúrgica según los criterios del Centers for Disease Control and Prevention Hospital Infection. Resultados La mediana de edad fue de 68 años (rango 25-88), el 65% eran hombres, el 59% eran ASA 3-4, el cumplimiento del protocolo se realizó en más del 80% en los distintos apartados y se realizó acceso laparoscópico en el 31%. La incidencia de la infección de la herida quirúrgica superficial y profunda fue del 25%. Los pacientes con infección presentaron una mayor prevalencia de diabetes (48 vs 24%), de transfusión (56 vs 28%), de íleo paralítico (48 vs 18,7%) y de absceso intraabdominal (16 vs 3%). El analisis multivariante relacionó la hemoglobina y la glucemia preoperatorias, y la duración de la cirugía con la infección incisional. Conclusiones El protocolo de prevención no influyó en la incidencia de infección de la herida quirúrgica (AU)
