Whole blood in trauma resuscitation

Bedside ultrasound performed by emergency clinicians for diagnosis and procedures.

Key point: Focused transesophageal echocardiography should only be performed during advanced cardiopulmonary resuscitation or unclear shock when focused transthoracic echocardiography cannot clarify the issue.

Rapid rule-in and rule-out algorithms for myocardial infarction using high-sensitivity troponin.

Key point: The ESC 0/1-hour pathway did not increase 4-hour discharge versus 0/3-hour testing but was noninferior for discharge safety.

Patients held in the emergency department while waiting for an inpatient bed, and its effects.

Tranexamic acid in trauma and other acute haemorrhage.

Key point: Tranexamic acid does not affect all-cause mortality, functional outcomes, neurological impairment, or hematoma expansion in spontaneous intracerebral hemorrhage, despite reducing hematoma volume.

Video laryngoscopes for tracheal intubation.

Key point: For neonatal and infant airway management, videolaryngoscopy is the first choice for intubation, with apneic oxygenation during the attempt.

Using ECMO during cardiac arrest when conventional CPR fails.

Key point: Extracorporeal CPR may be considered for selected in-hospital pediatric arrests unresponsive to conventional CPR in appropriately resourced hospitals, with insufficient evidence for out-of-hospital use.
