Clinical Manifestations and Pathogenic Characteristics of Different Types of Deep Sternal Wound Infection in after Cardiac Surgery / 中国医科大学学报

ABSTRACT

Objective To investigate the clinical features and pathogenic characteristics of different types of deep sternal wound infection in dif?ferent types after cardiac surgery. Methods A retrospective study was performed. From January 2012 to December 2014,84 patients with sec?ondary DSWI after cardiac surgery underwent the pectoralis major muscle flap transposition in our department were recruited for the study. Re?sults The average age of 84 patients with DSWI was 54.6 ± 14.8 years old,of which typeⅡDSWI patients were the most common(49/84, 58.3%). Both typeⅠand typeⅡDSWI patients showed typical clinical manifestations and early chest X?ray or Computerized tomography(CT) showed mediastinal widening(P0.05),but the pathogenic results of the 3 types of those DSWI patients showed such a trendtypeⅠDSWI patients with GNB is was more common,and typeⅡDSWI patients was more prone to complicated infection. Conclusion Different types of DSWI may dis?play different features,the prevention and treatment of DSWI should be closely combined with the clinical manifestations and local pathogenic char?acteristics.
