e., identification of bacteria

and microorganismal pathogens within the peritoneal fluid, the presence of yeasts (if applicable), and the antibiotic susceptibilities Raf inhibitor of bacterial isolates. Statistical analysis Following data entry into a computerized database, the results will be expressed as standard statistical metrics: median (range), mean ± standard deviation for continuous variables, and the number of patients (with the corresponding percentages) for other qualitative variables. The primary endpoints will include Clinical profiles of intra-abdominal infections Epidemiological profiles (the learn more epidemiology of the microorganisms isolated from intra-abdominal samples and these organisms’ resistance to antibiotics) Management profiles

Comparisons will be performed using the Student’s t-test, χ 2 analysis, or the Kruskall-Wallis/Wilcoxon tests, as dictated by the natural parameters of the data in question. Statistical significance check details will be defined as a P-value less than 0.05 (P < 0.05). Multivariate analysis will be carried out by means of stepwise logistic regressions in order to assess the predictive factors of mortality during hospitalization. Adjusted odds ratios (OR) and their 95% confidence intervals (CI) will also be included. Inclusion Criteria Patients undergoing surgery or interventional drainage to address complicated IAI, or patients who have yieded positive microbiological cultures upon postoperative drainage (intra-abdominal samples taken from surgery or drainage) will be Cyclic nucleotide phosphodiesterase included. Exclusion Criteria

Patients with pancreatitis and primary peritonitis will be excluded. References 1. Menichetti F, Sganga G: Definition and classification of intra-abdominal infections.
