This case series examines the spectrum of imaging findings at chest radiography, US, CT, and MRI in 35 children admitted to a tertiary pediatric hospital in April and May 2020 with a post–coronavirus disease 2019 inflammatory condition known as multisystem inflammatory syndrome in children. The constellation of findings includes airway inflammation and rapid development of pulmonary edema on thoracic images, coronary artery aneurysms, and extensive right iliac fossa inflammatory changes on abdominal images. Awareness of this emerging condition and the expected multi-organ imaging findings will aid radiologists in the assessment of these complex cases. © RSNA, 2020

The six-view ACES protocol is a useful adjunct to clinical examination in patients with undifferentiated hypotension in the emergency department. A prospective randomised trial or multicentre database/registry is needed to investigate the validity and impact of this protocol on the early diagnosis and management of hypotensive patients.

Background: Emergency rapid sequence intubation (RSI) performed outside the operating room on emergency patients is the cornerstone of emergency airway management. Complication rates are unknown for this procedure in the United Kingdom and the factors contributing to immediate complications have not been identified. Aims: To quantify the immediate complications of RSI and to assess the contribution made by environmental, patient, and physician factors to overall complication rates. Methods: Prospective observational study of 208 consecutive adult and paediatric patients undergoing RSI over a six month period. Results: Patients were successfully intubated by RSI in all cases. There were no deaths during the procedure and no patient required a surgical airway. Patient diagnostic groups requiring RSI are described. Immediate complications were hypoxaemia 19.2%, hypotension 17.8%, and arrhythmia 3.4%. Hypoxaemia was more common in patients with pre-existing respiratory or cardiovascular conditions than in patients with other diagnoses (p,0.01). Emergency department intubations were associated with a significantly lower complication rate than other locations (16.9%; p = 0.004). This can be explained by the difference in diagnostic case mix. Intubating teams comprised anaesthetists, non-anaesthetists, or both. There were no significant differences in complication rates between these groups. Conclusions: RSI has a significant immediate complication rate, although the clinical significance of transient events is unknown. The likelihood of immediate complications depends on the patient's underlying condition, and relevant diagnoses should be emphasised in airway management training. Complication rates are comparable between anaesthetists and non-anaesthetists. The significantly lower complication rates in emergency department RSI can be explained by a larger proportion of patients with comparatively stable cardiorespiratory function.

Survival rates following traumatic cardiac arrest (TCA) are known to be poor but resuscitation is not universally futile. There are a number of potentially reversible causes to TCA and a well-defined group of survivors. There are distinct differences in the pathophysiology between medical cardiac arrests and TCA. The authors present some of the key differences and evidence related to resuscitation in TCA, and suggest a separate algorithm for the management of out-of-hospital TCA attended by a highly trained physician and paramedic team.

BackgroundEvery day throughout the UK, ambulance services seek medical assistance in providing critically ill or injured patients with pre-hospital care.ObjectiveTo identify the current availability and utilisation of physician-based pre-hospital critical care capability across England, Wales and Northern Ireland.DesignA postal and telephone survey was undertaken between April and December 2009 of all 13 regional NHS ambulance services, 17 air ambulance charities, 34 organisations affiliated to the British Association for Immediate Care and 215 type 1 emergency departments in England, Wales and Northern Ireland. The survey focused on the availability and use of physician-based pre-hospital critical care support.ResultsThe response rate was 100%. Although nine NHS ambulance services recorded physician attendance at 6155 incidents, few could quantify doctor availability and utilisation. All but one of the British Association for Immediate Care organisations deployed ‘only when available’ and only 45% of active doctors could provide critical care support. Eleven air ambulance services (65%) operated with a doctor but only 5 (29%) operated 7 days a week. Fifty-nine EDs (27%) had a pre-hospital team but only 5 (2%) had 24 h deployable critical care capability and none were used regularly.ConclusionThere is wide geographical and diurnal variability in availability and utilisation of physician-based pre-hospital critical care support. Only London ambulance service has access to NHS-commissioned 24 h physician-based pre-hospital critical care support. Throughout the rest of the UK, extensive use is made of volunteer doctors and charity sector providers of varying availability and capability.
