In 2011, the Fourth National Audit Project (NAP4) reported high rates of airway complications in adult intensive care units (ICUs), including death or brain injury, and recommended preparation for airway difficulty, immediately available difficult airway equipment and routine use of waveform capnography monitoring. More than 80% of UK adult intensive care units have subsequently changed practice. Undetected oesophageal intubation has recently been listed as a 'Never Event' in UK practice, with capnography mandated. ⋯ Death or serious harm occurring secondary to complications of airway management in the last 5 years was reported in 19% of paediatric intensive care units and in 26% of neonatal intensive care units. We conclude that major gaps in optimal airway management provision exist in UK paediatric intensive care units and especially in UK neonatal intensive care units. Wider implementation of waveform capnography is necessary to ensure compliance with the new 'Never Event' and has the potential to improve airway management.

Randomized Controlled Trial
Effect of a single pre-operative 125 mg dose of methylprednisolone on postoperative delirium in hip fracture patients; a randomised, double-blind, placebo-controlled trial.
Postoperative delirium is common after hip fracture surgery, and may have a neuro-inflammatory cause. We conducted a single-centre, randomised, double-blind, placebo-controlled trial of 117 older hip fracture patients to see if a single, pre-operative intravenous dose of 125 mg methylprednisolone could reduce the severity and/or incidence of postoperative delirium, assessed using the Confusion Assessment Method delirium severity score. Modified intention-to-treat analysis found no significant difference in our primary outcome, median (IQR [range]) cumulative Confusion Assessment Method delirium severity score over the first three postoperative days between the methylprednisolone and placebo groups (1 (0-6 [0-39]) vs. 2 (0-10 [0-32]), p = 0.294). ⋯ There were no significant between-group differences in the rate of completing physiotherapy, postoperative pain, the administration of antipsychotic drugs, infection, length of inpatient stay or 30- and 90-day mortality. No major adverse reactions related to methylprednisolone were recorded. We conclude that a single, pre-operative dose of 125 mg methylprednisolone does not reduce the severity of postoperative delirium, but may reduce both the prevalence of delirium and the severity of fatigue after hip fracture surgery in older patients, enabling remobilisation and recovery.

It is unclear whether the time of day for emergency surgery is associated with postoperative mortality. We assessed this association in 9319 patients who had emergency surgery as their first surgery at the Jewish General Hospital, Montreal, QC, Canada from April 2010 to March 2015. ⋯ There was no significant association of time of day with postoperative mortality, with adjusted OR (95%CI) of 1.61 (0.96-2.72) for night vs. day, p = 0.07; 1.29 (0.78-2.13) for night vs. evening, p = 0.33; and 1.26 (0.89-1.78) for evening vs. day, p = 0.20. Studies of more patients and more factors, with longer follow-up, should be carried out to exclude important associations of time of emergency surgery with postoperative mortality and morbidity.
