Determinants of Length of Intensive Care Unit Stay After Simultaneous Aortic and Mitral Valve Replacement
Authors' conclusion
Age, preoperative left ventricular ejection fraction, cardiopulmonary bypass time, intraoperative blood product transfusion, intra-aortic balloon pump insertion, ventilation time, occurrence of atrial fibrillation, and positive inotropic agent usage were independent determinants of the length of ICU stay at various proposed stages in patients undergoing simultaneous AVR and MVR.
Study context

Main finding
As reported in the abstract
Independent determinants of Ln (length of ICU stay), by stage
- Before surgery: age independently associated with Ln (length of intensive care unit (ICU) stay)
- At ICU admission: age, preoperative left ventricular ejection fraction, CPB time, intraoperative blood product transfusion and intra-aortic balloon pump insertion independently correlated
- During ICU stay: ventilation time, AF, positive inotropic agent use and all the above variables independently associated
- Multivariable analysis
Observational data: associations, not effects.
