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.

Transesophageal echocardiography for verification of the position of the electrocardiographically-placed central venous catheter.
Compare changes in P-wave amplitude of the intra-atrial electrocardiogram (ECG) and its corresponding transesophageal echocardiography (TEE)-controlled position to verify the exact localization of a central venous catheter (CVC) tip. ⋯ The study suggests that the position of the CVC tip is located parallel to the SVC and 1.5 cm above the crista terminalis if the P wave starts to decrease during withdrawal of the catheter. The authors recommend that ECG control as per their study should be routinely used for placement of central venous catheters via the right internal jugular vein.

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 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.
