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.

Randomized Controlled Trial Comparative StudyA comparison of the deflecting-tip bronchial blocker with a wire-guided blocker or left-sided double-lumen tube.
To compare a new bronchial blocker, the Cohen blocker, with the Arndt blocker and a left double-lumen tube (DLT). ⋯ There was a trend toward a difference between times to place a bronchial blocker and the DLT. The Cohen blocker is more difficult to position in the left main bronchus than in the right one.

Comparative StudyTwo-lung high-frequency jet ventilation as an alternative ventilation technique during transthoracic esophagectomy.
The aim of this study was to evaluate two-lung high-frequency jet ventilation during esophagectomy and evaluate the influence of high-frequency jet ventilation on pulmonary complications as compared with one-lung ventilation. ⋯ High-frequency jet ventilation to 2 lungs, using a single-lumen tube, is a safe and adequate ventilation technique for use during esophagectomy. High-frequency jet ventilation had no influence on the incidence of postoperative pulmonary complications but reduced perioperative blood loss and led to a decreased need for fluid replacement.
