Perfil epidemiológico y resistencia a los antibióticos de los gérmenes más frecuentes en líquido peritoneal en los pacientes pediátricos con diagnóstico de peritonitis secundaria a apendicitis en el Hospital Roberto Gilbert Elizalde en el periodo de noviembre 2016 a octubre 2017.

Abstract

Background. Bacterial secondary peritonitis is a serious complication of appendicitis. Added to a growing resistance of the pathogenic microoganisms involved in this nosological entity increases morbidity and mortality and health costs. Resistance to antibiotics remains one of the most important public health problems, despite multiple efforts aimed at prevention and control. It is important permanent updating of knowledge improving current perspectives of comprehensive treatment of patients with bacterial peritonitis in the postoperative stage, therefore the objective of this study is to determine the sensitivity and resistance of isolated germs in peritoneal fluid cultures of patients with peritonitis secondary to appendicitis and its response to antimicrobials. Materials and methods: a descriptive, retrospective study conducted in 192 patients with established inclusion criteria, attended in the area of pediatric surgery of the Roberto Gilbert Elizalde Hospital. Data collection was performed based on the review of single clinical history records of pediatric patients that are included in the Servinter system. Frequencies and percentages were used for the analysis. Results: The average age of the patients with appendiceal peritonitis was of 9.8 years, with predominance in male sex with 64.1%, the germs isolated in peritoneal fluid of studied population were E. coli in 70.3% of cases, E. coli producing strain of ESBL, in 16.2% of cases, Pseudomonas aeruginosa in 10.8% of cases and Klebsiella pneumoniae with 2.7%. Conclusions: that strains isolated in peritoneal fluid cultures of patients with peritonitis secondary to appendicitis were sensitive to the antimicrobials.
