Diagnosis of perioperative anaphylaxis is difficult because of its non-specific and variable signs and symptoms. Therapeutic agents used to treat anaphylaxis and anaesthesiologist responses also vary depending on the case, which might affect outcomes; however, only a few studies have focused on these factors. ⋯ UMIN000035350.

'Where there's smoke': longitudinal cognitive disintegration after postoperative delirium?
Postoperative delirium is an important complication of surgery and is associated with poor long-term cognitive outcomes, although the neural basis underlying this relationship is poorly understood. Neuroimaging studies and network-based approaches play an important role in our understanding of the mechanism by which delirium relates to longitudinal cognitive decline. A recent resting state functional MRI study is reviewed, which shows reduced global connectivity up to 3 months after delirium, supporting recent models of delirium and opening the door for applying this approach to understanding the complex inter-relationship between delirium and dementia.

Preventing difficult facemask ventilation in children: all is well that starts well.
Difficult facemask ventilation at induction of general anaesthesia can trigger hypoxaemia and inadequate ventilation if not immediately identified and adequately treated. For this reason, identification of predisposing conditions before induction of anaesthesia and causes of poor facemask ventilation are critical to avoid the subsequent complications. In a recently published secondary analysis of the Paediatric Difficult Intubation (PeDI) registry, the incidence and risk factors for difficult facemask ventilation in children with difficult tracheal intubation was described, as highlighted in the editorial.

Treatment of perioperative anaphylaxis: room for improvement?
Perioperative anaphylaxis is associated with significant morbidity and mortality. Prompt and appropriate treatment is required for optimal outcome. Despite general knowledge of this condition, delays occur in the administration of epinephrine and in particular the use of i.v. route of administration in the perioperative setting. Barriers should be addressed to allow prompt utilisation of i.v. epinephrine in perioperative anaphylaxis.
