Epidemiology of deep sternal wound infection in cardiac surgery.
The aim of this study was to investigate the incidence and predictors of deep sternal wound infection (DSWI) in a contemporary cohort of patients undergoing cardiac surgery. The early and late outcomes of patients with this complication also were analyzed. ⋯ DSWI remains a rare but devastating complication and is associated with significant comorbidity, increased hospital mortality, and reduced long-term survival.

Predictors of prolonged mechanical ventilation after aortic arch surgery with deep hypothermic circulatory arrest plus antegrade selective cerebral perfusion.
The predictors of prolonged mechanical ventilation after aortic arch surgery with deep hypothermic circulatory arrest have not been comprehensively evaluated. The present study was designed to identify variables associated with prolonged ventilation in a group of aortic arch surgery patients from a single center. ⋯ The authors identified 4 preoperative and intraoperative predictors associated with increased risk of prolonged mechanical ventilation. This is helpful to identify patients with increased risk for prolonged ventilation, develop preemptive strategies, and allocate medical resources.

The feasibility of speckle tracking for intraoperative assessment of regional myocardial function by transesophageal echocardiography.
The authors aimed to examine the feasibility of intraoperative transesophageal echocardiography (TEE) acquisition of a non-Doppler-based, speckle tracking-derived myocardial deformation parameter (strain) immediately before and after coronary artery bypass graft (CABG) surgery in patients with reduced left ventricular (LV) function. ⋯ Strain calculation from TEE images is feasible during cardiac surgery and correlates well with WMS but has better interobserver agreement. Strain analysis, but not WMS, detected wall motion differences between normally perfused and ischemic segments. This simple method allows objective intraoperative quantification of myocardial segment function and may become an important monitoring tool in the future.

The impact of lung recruitment on hemodynamics during one-lung ventilation.
The objective of the present study was to investigate respiratory and hemodynamic changes by measuring continuous cardiac output, cardiac filling, and stroke volume variation after lung recruitment in thoracic surgery. ⋯ The authors concluded that during open-chest surgery with OLV, an ARM effectively improved oxygenation without inducing important circulatory changes.

Preoperative statin administration is associated with lower mortality and decreased need for postoperative hemodialysis in patients undergoing coronary artery bypass graft surgery.
The purpose of this study was to examine the effect of perioperative statin administration on renal outcomes after cardiac surgery. ⋯ The preoperative use of statins is associated with decreased in-hospital mortality and a reduction in the need for RRT.
