Clinical presentation, aetiological characteristics, risk factors and in-hospital outcome of nosocomial infection following acute aortic dissection surgery in adult patients

This study identified the high morbidity and mortality of NI after AADS. The most common types of infection were HAP, VAP and BSI, and the pathogenic microorganisms were Klebsiella pneumoniae, Pseudomonas aeruginosa and Acinetobacter baumannii. Total protein, serum albumin, eGFR, longer operation time and CPB time, second operation in-hospital, exposure to ECMO and CRRT, and PPI use were independent risk factors for the occurrence of NI.
