Randomized Controlled TrialBenefits of Using High-Volume-Low-Pressure Tracheal Tube in Children Undergoing Congenital Cardiac Surgery: Evidence From a Prospective Randomized Study.
In the past 2 decades, usage of high-volume-low-pressure microcuffed tracheal tubes in smaller children has increased. However, there is paucity of evidence of its usage in smaller children undergoing congenital cardiac surgery. The aim of this study was to assess if microcuff endotracheal tubes in neonates and younger children undergoing congenital cardiac surgery is associated with better outcomes than uncuffed tubes. ⋯ Microcuff pediatric tracheal tube is associated with significantly lower incidence of stridor, tube changes, and anesthetic gas requirement. This leads to significant cost reduction that offsets the higher costs associated with usage of a microcuff tracheal tube.

Randomized Controlled TrialEffects of nondependent lung ventilation with continuous positive-pressure ventilation and high-frequency positive-pressure ventilation on right-ventricular function during 1-lung ventilation.
Background. The application of volume-controlled high frequency positive pressure ventilation (HFPPV) to the nondependent lung (NL) may have comparable effects to continuous positive airway pressure (CPAP) on the right ventricular (RV) function, oxygenation, and surgical conditions during one lung ventilation (OLV) for thoracotomy. Methods. ⋯ The application of NL-HFPPV resulted in improved REF by 33%, SVI and DO2 (P < 0.01) and reduced RVEDVI, RVSWI, PVRI, oxygen uptake, and shunt fraction by 24.8% (P < 0.01) than in the NL-CPAP groups. Conclusion. We concluded that the use of NL-HFPPV is a feasible option and offers improved RV function and oxygenation during OLV for open thoracotomy.

Randomized Controlled Trial Comparative StudyCardiac protection during on-pump coronary artery bypass grafting: ischemic versus isoflurane preconditioning.
To compare the cardioprotective effects of anesthetic preconditioning by isoflurane with ischemic preconditioning. ⋯ Based on this very small sample size, these data support a cardioprotective effect of isoflurane and ischemic preconditioning during CABG surgery.
