Comparative Study
Basic life support providers' assessment of centre of the chest and inter-nipple line for hand position and their underlying anatomical structures.
Effective chest compression is an integral part of good quality cardiopulmonary resuscitation. There remains uncertainty over the optimal method for identifying the correct hand position for chest compression. The aim of this study was to identify the relationship between basic life support (BLS) providers assessment of the inter-nipple line (INL) versus the centre of the chest (CoC) and to identify the anatomical structures underneath these landmarks. ⋯ Both the centre of the chest landmark and inter-nipple line identify positions on the lower third of the sternum. The centre of the chest technique identifies a point that is consistently higher and more variable than the inter-nipple line. Structures compressed under both landmarks were different although the implications of this are unknown.

To determine whether team performance in a simulated emergency is related to generic teamwork skills and behaviours. ⋯ The clinical conduct of a simulated emergency was strongly linked to generic measures of teamwork. Further studies are needed to elucidate which aspects of team working are critical for team performance, to better inform training programs for multi-professional team working.

Comparative Study
Does prearrest adrenergic integrity affect pressor response? A comparison of epinephrine and vasopressin in a spontaneous ventricular fibrillation swine model.
Coronary perfusion pressure (CPP) during resuscitation from cardiac arrest has been shown to correlate with return of spontaneous circulation. Adrenergic blockade of beta-1 and alpha-1 receptors is common in the long-term management of ischemic heart disease and congestive heart failure. We sought to compare the CPP response to vasopressin vs. epinephrine in a swine model of cardiac arrest following pre-arrest adrenergic blockade. ⋯ Pre-arrest adrenergic blockade blunts the CPP response to epinephrine. Superior augmentation of CPP is attained with vasopressin under these conditions.

To determine whether cardiac arrest calls, the proportion of adult patients admitted to intensive care after CPR and their associated mortalities were reduced, in a four year period after the introduction of a 24/7 Critical Care Outreach Service and MEWS (Modified Early Warning System) Charts. ⋯ The four years following the introduction of a 24/7 Critical Care Outreach Service and MEWS Charts were associated with significant reductions in the incidence of cardiac arrest calls, the proportion of patients admitted to intensive care having undergone in-hospital CPR and their in-hospital mortality.
