Review Comparative Study
Emergency department factors associated with survival after sudden cardiac arrest.
Sudden cardiac arrest (SCA) is a leading cause of death in the US. Recent innovations in post-arrest care have been demonstrated to increase survival. However, little is known about the impact of emergency department (ED) and hospital characteristics on survival to hospital admission and ultimate outcome. ⋯ An estimated 175,000 cases of SCA present to or occur in US EDs each year. Percutaneous coronary intervention capability, ED volume, and teaching status were associated with higher survival to hospital admission. Emergency departments with higher annual SCA volume had lower survival rates, possibly because they transfer fewer patients. An improved understanding of the contribution of ED care to survival following SCA may be useful in advancing our understanding of how best to organize a system of care to ensure optimal outcomes for patients with SCA.

Resuscitation of the pregnant patient: What is the effect of patient positioning on inferior vena cava diameter?
Patients in the third trimester of pregnancy presenting to the emergency department (ED) with hypotension are routinely placed in the left lateral tilt (LLT) position to relieve inferior vena cava (IVC) compression from the gravid uterus thereby increasing venous return. However, the relationship between patient position and proximal intrahepatic IVC filling has never assessed directly. This study set out to determine the effect of LLT position on intrahepatic IVC diameter in third trimester patients under real-time visualization with ultrasound. ⋯ IVC ultrasound is feasible in late pregnancy and demonstrates an increase in diameter with LLT positioning. However, a quarter of patients had a decrease in IVC diameter with tilting and, instead, had the largest IVC diameter in the supine position suggesting that uterine compression of the IVC may not occur universally. IVC assessment at the bedside may be a useful adjunct in determining optimal positioning for resuscitation of third trimester patients.

Randomized Controlled Trial Multicenter Study Comparative Study
Development and validation of a multiple choice examination assessing cognitive and behavioural knowledge of pediatric resuscitation: a report from the EXPRESS pediatric research collaborative.
Assessing the knowledge of Pediatric Advanced Life Support (PALS) based learning objectives of medical trainees is an important evaluation component for both residency programs and for research studies. In this study, a multiple-choice question (MCQ) examination was developed and validated for use in a larger pediatric simulation resuscitation study (EXPRESS study). ⋯ This short MCQ examination demonstrated reasonable reliability and construct validity. It may be useful to assess pediatric resuscitation knowledge in future studies or courses.

Multicenter Study Comparative Study
Chest injury following cardiopulmonary resuscitation: a prospective computed tomography evaluation.
Traumatic chest injuries may occur following cardiopulmonary resuscitation (CPR). The aim of this study was to address the frequency of injuries, especially rib and sternal fractures, and also to identify factors that contribute to post-CPR trauma. ⋯ The incidence of rib fracture following CPR was different in various hospitals. The presence of non-physician chest compressors in the ED was one of the contributing factors to rib fracture. Further studies on the influence of resuscitators and relation between quality of chest compression and CPR-induced injuries are warranted to reduce complications following CPR.
