To determine whether 80-lead body surface potential mapping (BSPM) improves detection of acute coronary artery occlusion in patients presenting with out-of-hospital cardiac arrest (OHCA) due to ventricular fibrillation (VF) and who survived to reach hospital. ⋯ Among OHCA patients presenting with VF and who survived resuscitation to reach hospital, post-resuscitation BSPM STE identifies acute coronary occlusion with sensitivity 88% and specificity 100% (c-statistic 0.94).

It is unclear whether the basic life support (BLS) and advanced life support (ALS) pre-hospital termination of resuscitation (TOR) rules developed in North America can be applied successfully to patients with out-of-hospital cardiac arrest (OHCA) in other countries. ⋯ The prehospital BLS and ALS TOR rules performed well in Japan with high specificity and PPV for predicting lack of neurologically favorable one-month survival in Japan. However, the specificity and PPV were not 1000 and we have to develop more specific TOR rules.

Adherence to Advanced Trauma Life Support (ATLS) protocol has been associated with improved management of injured patients. The objective of this study is to determine factors associated with delayed and omitted ATLS primary and secondary survey tasks at a level 1 pediatric trauma center. ⋯ Mechanism of injury and hospital factors are associated with incomplete and delayed primary and secondary surveys. Interventions that address deficient ATLS adherence related to these factors may lead to a reduction in errors during this critical period of patient care.

There has been controversy over whether a short period of cardiopulmonary resuscitation (CPR) prior to defibrillation improves survival in patients who experienced a sudden cardiac arrest. However, there have been no reports about whether CPR restores the myocardial energy source during prolonged ventricular fibrillation (VF). The aim of this study is to investigate the effect of CPR in restoring myocardial high energy phosphates during prolonged VF. ⋯ CPR for 2 min helps to maintain myocardial ATP after prolonged VF.
