Intra-abdominal infections. Update and recommendations

Intra-abdominal infections represent a group of intra and retroperitoneal processes, ranging from localized infections to complicated ones, sepsis and septic shock. associated with a significant mortality rate. They are the third most commonly identified cause of sepsis and the second cause of death in the intensive care unit. Although antimicrobial therapy must be started as soon as possible, especially in critically ill patients, the source control procedure is highly relevant. On account of the importance of this subject, members of the Argentine Society of Infectious Diseases (SADI) and intensive care specialists joined to develop recommendations on diagnosis. treatment, and prevention of intra-abdominal infections. The literature published within the last 10 years was reviewed and analyzed, in addition of expert opinions and local data. This statement provides a basic tool for diagnosis based on clinical and microbiological criteria, orientation on empirical antimicrobial therapy schemes according to source. acquisition place (community or healthcare associated infections), infection severity, treatment duration, importance of source control, and preventive measures aimed to reduce surgical site infection risk. Likewise, it provides a simple algorithm for diagnosis and treatment for use in clinical practice. The work reveals the concern about the management of intra-abdominal infections, establishing local guidelines to optimize diagnosis, treatment and prevention, with the aim of reducing morbidity, mortality, length of stay, costs and antimicrobial resistance.
