Background
Pulmonary complications after cardiac surgery are a leading cause of morbidity and mortality. The aim of this study was to develop predictive models for postoperative lung dysfunction and mortality.
Methods
This was a single-center, observational, retrospective study, which took place in a tertiary care University Hospital. We retrospectively analyzed data regarding 11285 adult patients who underwent all types of cardiac surgery from 2003 to 2015.
We developed logistic predictive models for in-hospital mortality, for postoperative pulmonary complications (PPC) occurring in the intensive care unit (ICU), and the need for postoperative non-invasive mechanical ventilation (NIMV) when clinically indicated.
Results
Age, preoperative ejection fraction, New York Heart Association (NYHA) class, emergency surgery, pharmacological and mechanical circulatory support, creatinine peak in the ICU, tracheostomy, and a lower PaO2/FiO2 ratio at ICU discharge were predictors of mortality. Age, ejection fraction, body mass index, creatinine peak in the ICU, blood-product use, inotropic support, and a lower PaO2/FiO2 ratio were predictors of postoperative NIMV. Preoperative lung disease, ejection fraction, NYHA class, inotropic and mechanical support, and preoperative serum creatinine were predictors of PPC.
Conclusions
We provide three models for the prediction of major pulmonary complications and mortality following cardiac surgery.
