To examine trends in survival from 2006 to 2018 and to assess whether the introduction of resuscitation guidelines was associated with a change in survival after adult in-hospital cardiac arrest. ⋯ In-hospital cardiac arrest survival increased from 2006 to 2010, after which the trend plateaued. The annual survival trend was lower following publication of the 2010 and 2015 guidelines. Research targeting in-hospital cardiac arrest as a unique entity may be necessary to improve outcomes.

Traditional assessment of return of cardiac output in cardiac arrest by manual palpation has poor accuracy. Point of care ultrasound of a major artery has been suggested as an alternative. We conducted a diagnostic accuracy study of two-dimensional carotid ultrasound to detect the presence or absence of a pulse, using cardiopulmonary bypass patients for pulse and pulseless states. ⋯ 2D ultrasound of the common carotid artery is both sensitive and specific for detection of the presence or absence of a pulse.

The aim of this study is to analyse the causes of cardiac arrests (CA) in the emergency departments (ED) in the United States and their clinical outcomes according to whether they had a primary or a secondary diagnosis of CA. ⋯ Survival with CA in ED is <30% of patients and is greater among patients with a secondary diagnosis of CA. CAs are associated with significant mortality in ED and hospital settings and measures should be taken to better manage cardiac, infection and respiratory causes particularly in the winter months.
