Randomized Controlled Trial Comparative StudyContinuous Positive Airway Pressure Versus Oxygen Therapy in the Cardiac Surgical Ward: A Randomized Trial.
Noninvasive ventilation (NIV) is a common technique to manage patients with acute respiratory failure in the intensive care unit. However, use of NIV in general wards is less well described. The authors' aim was to demonstrate efficacy of NIV, applied in a cardiac surgery ward, in improving oxygenation in patients who developed hypoxemic acute respiratory failure after being discharged from the intensive care unit. ⋯ Among patients with acute respiratory failure following cardiac surgery, administration of continuous positive airway pressure in the main ward was associated with improved respiratory outcome. This was the first study that was performed in the main ward of post-surgical patients with acute respiratory failure.

Accuracy and Trending Ability of the Fourth-Generation FloTrac/Vigileo System in Patients With Low Cardiac Index.
To determine the accuracy and trending ability of the fourth-generation FloTrac/Vigileo in patients with low cardiac index by comparing FloTrac/Vigileo-derived cardiac index with that measured by 3-dimensional echocardiography. ⋯ The degree of accuracy of the fourth-generation FloTrac/Vigileo in patients with low cardiac index was not acceptable, and high systemic vascular resistance in patients with low cardiac index may have contributed to this inaccuracy. The tracking ability of the fourth-generation FloTrac/Vigileo after phenylephrine administration or cardiac resynchronization therapy was below acceptable limits.

Randomized Controlled TrialUse of McGrath MAC Videolaryngoscope to Assist Transesophageal Echocardiography Probe Insertion in Intubated Patients.
Transesophageal echocardiography (TEE) probe insertion with the conventional blind insertion technique may be difficult in anesthetized and intubated patients. The use of a videolaryngoscope may facilitate the insertion of the TEE probe. The aim of this study was to compare the conventional technique with the use of the McGrath MAC videolaryngoscope for TEE probe insertion in terms of success rate, duration of insertion, and complications in patients undergoing cardiovascular surgery. ⋯ The use of the McGrath MAC videolaryngoscope for TEE insertion in cardiovascular surgery patients increases the success rate and reduces pharyngeal injuries compared to the conventional technique. The use of the McGrath MAC videolaryngoscope for TEE insertion causes similar hemodynamic changes as in the conventional blind insertion technique.
