Assessment of preparedness of weaning has been recommended before extubation for mechanically ventilated patients. We aimed to understand the association of a structured assessment of weaning preparedness with successful liberation. ⋯ Assessing the pre-extubation status of intubated patients in a checklist-based approach using the WEANSNOW score might provide valuable insights into extubation failure in patients in a medical ICU for acute respiratory failure. Further prospective studies are warranted to elucidate the practice of assessing weaning preparedness.

Ventilator Withdrawal in Anticipation of Death: The Simulation Lab as an Educational Tool in Palliative Medicine.
Simulation is a growing model of education in many medical disciplines. Withdrawal of mechanical ventilation is an important skill set for palliative medicine practitioners who must be facile with a variety of end-of-life scenarios and is well suited to the simulation laboratory. We describe a novel approach using high-fidelity simulation to design a curriculum to teach Hospice & Palliative Medicine fellows the practical aspects of managing a compassionate terminal extubation. ⋯ Based on feedback, the session is scheduled for the beginning of the academic year and each fellow is given the opportunity to physically remove the endotracheal tube. Simulation can be effectively used to teach practical and complex bedside skills such as withdrawal of mechanical ventilation to palliative medicine trainees. This method of teaching could be expanded to teach other advanced hospice and palliative care skills.

Variables predicting weaning outcome in prolonged mechanically ventilated tracheotomized patients: a retrospective study.
Several studies have assessed predictors of weaning and extubation outcome in short-term mechanically ventilated patients, but there are only few studies on predictors of weaning from prolonged mechanical ventilation. ⋯ In the present study, the derived predictors of weaning point to a crucial role of the workload imposed on respiratory muscles during spontaneous breathing. Mechanical power normalized to lung-thorax compliance was independently correlated with weaning outcome and may identify patients at high risk for weaning failure.

Inflammation is an important mechanism in the pathogenesis of delirium. Since delirium might reduce by anti-inflammatory effects of omega-3 fatty acids. Based on this respect, a study was conducted to indicate the effect of omega-3 fatty acids in the prevention of delirium in mechanically ventilated patients. ⋯ Omega-3 fatty acids can reduce the risk of delirium in mechanically ventilated patients.

Automatic cuff pressure (Pcuff) control devices for artificial airways are available, yet there are no standards or data to support their use. We hypothesized that airway pressure oscillations during mechanical ventilation are transmitted to Pcuff; and that the change in mean Pcuff (ΔPcuff) is zero during mechanical ventilation with controlled or uncontrolled Pcuff. ⋯ Automatic devices do not regulate ventilatory pressure oscillations, but they do control mean Pcuff and keep ΔPcuff well below a clinically important threshold. The large ΔPcuff seen with uncontrolled Pcuff warrants periodic monitoring. Further studies are needed to determine the source of ΔPcuff and the physiologic effects of Pcuff oscillations during mechanical ventilation.
