Oral tranexamic acid for immediate use in major trauma: implications for mass casualty events.

The early administration of tranexamic acid is recognised as significantly reducing mortality in traumatically injured patients with major haemorrhage, typically given via intravenous or intramuscular routes. In the context of mass casualty events, there may exist multiple traumatically injured casualties that would benefit from tranexamic acid, however, it's administration may be delayed through the need to establish intravenous access. Additionally, if the initial assessment of the traumatically injured casualty is undertaken by an individual who cannot administer intravenous or intramuscular medications, time to administration will be further delayed.

Incidence of admission ionised hypocalcaemia in paediatric major trauma: protocol for a systematic review and meta-analysis.

Introduction: Hypocalcaemia forms part of the 'diamond of death' in major trauma, alongside hypothermia, acidosis and coagulopathy. In adults, admission hypocalcaemia prior to transfusion is associated with increased mortality, increased blood transfusion requirements and coagulopathy. Data on paediatric major trauma patients are limited.

Comparison of deliberate self-harm incidents attended by Helicopter Emergency Medical Services before and during the first wave of COVID-19 in the East of England.

Introduction: There is significant interest in the mental health impact of the COVID-19 pandemic. Helicopter Emergency Medical Services (HEMS) attend the most seriously unwell and injured patients in the community; their data therefore present an early opportunity to examine self-harm trends. The primary aim was to compare the incidence of deliberate self-harm incident (DSH-I) encounters by HEMS before and during the first wave of COVID-19.

End-tidal and arterial carbon dioxide gradient in serious traumatic brain injury after prehospital emergency anaesthesia: a retrospective observational study.

Objectives: In the UK, 20% of patients with severe traumatic brain injury (TBI) receive prehospital emergency anaesthesia (PHEA). Current guidance recommends an end-tidal carbon dioxide (ETCO) of 4.0-4.
