Lung rest has been recommended during extracorporeal membrane oxygenation (ECMO) for severe acute respiratory distress syndrome (ARDS). Whether positive end-expiratory pressure (PEEP) confers lung protection during ECMO for severe ARDS is unclear. We compared the effects of three different PEEP levels whilst applying near-apnoeic ventilation in a model of severe ARDS treated with ECMO. ⋯ During near-apnoeic ventilation and ECMO in experimental severe ARDS, 10 cm H2O PEEP minimised lung injury and improved gas exchange without compromising haemodynamic stability.

Children's exposure to anaesthesia has been associated with risk of developing attention-deficit/hyperactivity disorder (ADHD). The goal of this study was to determine if selected patient characteristics moderate the association between exposure to anaesthesia and ADHD. ⋯ Exposure of young children to anaesthesia and surgery is associated with an increased incidence of ADHD, with more exposures associated with greater risk. Compared with White children, non-White children are at greater risk for reasons that are unknown but need to be further explored.

Tracheal intubation is among the most frequently performed manoeuvres in the critical care setting, and can be life-saving in critical illness, though also associated with serious adverse events such as oesophageal intubation or tracheal tube obstruction, displacement, or disconnection from the ventilator. A key finding of the 4th National Audit Project (NAP4) was identification of waveform capnography as the single intervention with the highest potential for reducing morbidity and mortality during tracheal intubation and maintenance of an artificial airway. In the INTUBE study, penetration of capnography into ICUs was low, and was not in use in 70% of the episodes of oesophageal intubation. To reduce harm and avoidable death, there is a need for a global initiative to increase access to and use of capnography in ICUs.

Opioid-overdose deaths are associated with poisoning with prescription and illicit opioids in the USA. In contrast, opioid-related deaths (ORDs) in the UK often involve drugs and substances of misuse, and may not be associated with a high dose of prescribed opioids. This study aimed to investigate the association between prescribed opioid dose and ORDs in UK primary care. ⋯ Daily OMEQ dose greater than 120 mg and the concomitant use of psychotropic medicines were related to ORDs in the UK. Prescribers should cautiously avoid prescribing opioids with a daily OMEQ dose greater than 120 mg day-1 and the combination of opioids and gabapentinoids, even with low opioid doses.
