Observational StudyThe SNAP index does not correlate with the State Behavioral Scale in intubated and sedated children.
Ensuring appropriate levels of sedation for critically ill children is integral to pediatric critical care. Traditionally, clinicians have used subjective scoring tools to assess sedation levels. The SNAP II uses dual frequency processed electroencephalography to evaluate brain activity and may provide an objective assessment of sedation levels. ⋯ The SNAP index does not correlate with SBS scores in our pediatric intensive care unit (PICU). Its use cannot be recommended to measure levels of sedation in our population. Future research should continue to explore objective ways of measuring sedation in critically ill children.

Multicenter StudyFactors associated with timing of initiation of physical therapy in patients with acute lung injury.
Early initiation of physical therapy (PT) in mechanically ventilated patients is associated with improved outcomes. However, PT is frequently delayed until after extubation or discharge from the intensive care unit (ICU). We evaluated factors associated with the timing of initiation of PT in patients with acute lung injury (ALI) admitted to ICUs without an emphasis on early rehabilitation. ⋯ In 11 ICUs without emphasis on early rehabilitation, patients with ALI frequently received no PT. Severity of illness, mental status, sedation practices, and hospital site were significant barriers to initiating PT. Understanding these barriers may be important when introducing early ICU physical rehabilitation.

Hypoxaemic rescue therapies in acute respiratory distress syndrome: Why, when, what and which one?
Acute respiratory distress syndrome (ARDS) is an inflammatory condition of the lungs which can result in refractory and life-threatening hypoxaemic respiratory failure. The risk factors for the development of ARDS are many but include trauma, multiple blood transfusions, burns and major surgery, therefore this condition is not uncommon in the severely injured patient. When ARDS is severe, high-inspired oxygen concentrations are frequently required to minimise hypoxaemia. ⋯ First line hypoxaemic rescue therapies include inhaled nitric oxide, prone positioning, alveolar recruitment manoeuvres and high frequency oscillatory ventilation, which have all been shown to be effective in improving oxygenation. In situations where these first line rescue therapies are inadequate extra-corporeal membrane oxygenation has emerged as a lifesaving second line rescue therapy. Rescue therapies in critically ill patients with traumatic injuries presents specific challenges and requires careful assessment of both the short and longer term benefits, therapeutic limitations, and specific adverse effects before their use.

We investigated a novel application of phrenic nerve stimulation (PNS) in diaphragm dysfunction induced by mechanical ventilation (MV). ⋯ PNS exerted a protective effect against MV-induced diaphragm dysfunction by counteracting altered expression of IGF-1 and ubiquitin ligase in the diaphragm.
