Comparative StudyHigh frequency oscillation and airway pressure release ventilation in pediatric respiratory failure.
Airway pressure release ventilation (APRV) and high frequency oscillatory ventilation (HFOV) are frequently used in acute lung injury (ALI) refractory to conventional ventilation. Our aim was to describe our experience with APRV and HFOV in refractory pediatric ALI, and to identify factors associated with survival. ⋯ In a heterogeneous PICU population with hypoxemia refractory to conventional ventilation transitioned to NCV, improvement in oxygenation at 24 hr was associated with survival. Immunocompromised status, number of vasopressor infusions, and the OI before transition to NCV were independently associated with survival.

Hospital-acquired delirium is a known risk factor for negative outcomes in patients admitted to the surgical intensive care unit (SICU). Outcomes worsen as the duration of delirium increases. The purpose of this study was to evaluate the efficacy of a delirium prevention program and determine whether it decreased the incidence and duration of hospital-acquired delirium in older adults (age>50 y) admitted to the SICU. ⋯ Although delirium prevention continues to be a challenge, this study successfully decreased the duration of delirium for older adults admitted to the SICU. Our simple, cost-effective program led to improved pain and sedation outcomes. Older adults with delirium spent less time on the ventilator and all patients spent less time in the SICU.

Multicenter Study
Mechanical ventilation during extracorporeal membrane oxygenation. An international survey.
In patients with severe, acute respiratory failure undergoing venovenous extracorporeal membrane oxygenation (VV-ECMO), the optimal strategy for mechanical ventilation is unclear. ⋯ Although ventilation practices in patients supported by VV-ECMO vary across ELSO centers internationally, the majority of centers used a strategy that targeted lung-protective thresholds and prioritized weaning VV-ECMO over mechanical ventilation.

Severe sepsis is the most common cause of death among critically ill patients in non-coronary intensive care units. In 2002, the guideline titled "Surviving Sepsis Campaign" was published by American and European Critical Care Medicine to decrease the mortality of severe sepsis and septic shock patients, which has been the basis of the treatment for those patients. ⋯ Other important revised guidelines in critical care field such as 'Clinical Practice Guidelines for the Management of Pain, Agitation, and Delirium in Adult Patients in the Intensive Care Unit' were revised in 2013. This article will review the revised guidelines and several additional interesting published papers of until March 2014, including the part of ventilator-induced lung injury and the preventive strategies.

Previous bench studies suggest that dynamic hyperinflation may occur if intrapulmonary percussive ventilation (IPV) is superimposed on mechanical ventilation in volume controlled continuous mandatory ventilation (VC-CMV) mode. We tested the hypothesis that pressure controlled continuous mandatory ventilation (PC-CMV) can protect against this risk. ⋯ When IPV is added to mechanical ventilation, the risk of hyperinflation is greater with VC-CMV than with PC-CMV. We recommend using PC-CMV to deliver IPV and adjusting the trigger variable to avoid autotriggering.
