[Purpose] The purpose of this study was to clarify the benefits of early mobilization for mechanically ventilated patients for their survival to discharge to home from the hospital. [Subjects and Methods] Medical records were retrospectively analyzed of patients who satisfied the following criteria: age ≥ 18 years; performance status 0-2 and independent living at their home before admission; mechanical ventilation for more than 48 h; and survival after mechanical ventilation. Mechanically ventilated patients in the early mobilization (EM) group (n = 48) received mobilization therapy, limb exercise and chest physiotherapy, whereas those in the control group (n = 60) received bed rest alone. Univariate and multivariate logistic regression analyses were performed to identify clinical variables associated with discharge disposition. [Results] Early mobilization was a positive independent factor and the presence of neurological deficits was a negative factor contributing to discharge to home. Among patients surviving mechanical ventilation without neurological deficits, the rate of discharge to home was significantly higher among patients in the EM group that in the control group (76% vs. 40%). [Conclusion] Early mobilization can improve the rate of discharge to home of patients requiring mechanical ventilation because of non-neurological deficits.

Comparative Study
Evaluation of an Automated Endotracheal Tube Cuff Controller During Simulated Mechanical Ventilation.
Maintaining endotracheal tube cuff pressure within a narrow range is an important factor in patient care. The goal of this study was to evaluate the IntelliCuff against the manual technique for maintaining cuff pressure during simulated mechanical ventilation with and without movement. ⋯ There was a clinically important drop in manually set cuff pressure during simulated mechanical ventilation in a stationary model and an even larger drop with movement, but this was significantly reduced by the IntelliCuff in both scenarios. Additionally, we observed that cuff pressure varied directly with inspiratory airway pressure for both techniques, leading to elevated average cuff pressures.

Current concepts in acute respiratory support for neonates and children.
Current trends in mechanical respiratory support are evolving toward gentle approaches to avoid short- and long-term problems that are historically associated with mechanical ventilation. These ventilator-associated issues include the need for long-term sedation, muscle deconditioning, ventilator-associated lung injury (VALI), and ventilator-associated pneumonia (VAP). This article will describe recent trends of ventilatory support in neonates and children: (1) utilization of volume ventilation in infants, (2) synchrony and improving patient-ventilator interaction specifically using neurally adjusted ventilatory assist (NAVA), and (3) use of noninvasive ventilation techniques. When applicable, their uses in the surgical newborn and pediatric patients are described.

Observational StudyPredicting duration of mechanical ventilation in patients with carbon monoxide poisoning: A retrospective study.
Patients with severe carbon monoxide (CO) poisoning may develop acute respiratory failure, which needs endotracheal intubation and mechanical ventilation (MV). The objective of this study was to identify the predictors for duration of MV in patients with severe CO poisoning and acute respiratory failure. ⋯ A positive toxin screen predicts extubation within the first 72 hours for patients with severe CO poisoning and acute respiratory failure. On the other hand, elevation of initial troponin-I level is a predictor for a longer duration of MV.
