Case Reports
Ruptured left subclavian artery aneurysm presenting as upper airway obstruction in von Recklinghausen's disease.
Aneurysms arising from the subclavian artery are very rare vascular abnormalities in von Recklinghausen's disease, which often have a silent clinical presentation and are difficult to diagnose before rupture. We report a case of von Recklinghausen's disease with life-threatening upper airway obstruction caused by spontaneous rupture of the left subclavian artery aneurysm in a 46-year-old woman. The diagnosis was eventually confirmed by a reconstructed enhanced computed tomography of aorta. We emphasise the importance of it as a differential diagnosis because life-threatening upper airway obstruction may develop in such patient.

Randomized Controlled Trial Multicenter Study
Retention of CPR skills learned in a traditional AHA Heartsaver course versus 30-min video self-training: a controlled randomized study.
Bystander CPR improves outcomes after out of hospital cardiac arrest. The length of current 4-h classes in cardiopulmonary resuscitation (CPR) is a barrier to more widespread dissemination of CPR training and older adults in particular are underrepresented in traditional classes. Training with a brief video self-instruction (VSI) program has shown that this type of training can produce short-term skill performance at least as good as that seen with traditional American Heart Association (AHA) Heartsaver training, although it is unclear whether there is comparable skill retention. ⋯ Retention of CPR skills was compared 2 months post-training for adults between 40 and 70 years old who had taken either a traditional Heartsaver CPR course or a 22-min video self-directed training course. Although performance declines occurred in the 2-month interval, self-trained subjects generally demonstrated CPR skill retention equivalent to that of Heartsaver-trained subjects, although for both groups skill decline on some measures reached the level of untrained controls.

The quality of cardiopulmonary resuscitation (CPR) plays a crucial role in saving lives from out-of-hospital cardiac arrest (OHCA). Previous studies have identified sub-optimal CPR quality in the prehospital settings, but the causes leading to such deficiencies were not fully elucidated. ⋯ Many unnecessary no-chest compression intervals were identified during ambulance CPR, and most of this was operator, rather than ambulance related. Though a mechanical device could minimise the no-chest compression intervals after activation, it took considerable time to deploy in a system with short transport time. Human factors remained the most important cause of poor CPR quality. Ways to improve the CPR quality in the ambulance warrant further study.

Studies have suggested that emesis may occur in up to a third of cardiac arrest patients. The goal of this investigation was to characterize the frequency, timing, and outcome association of emesis in persons suffering out-of-hospital cardiac arrest in order to understand the role and care-implications of emesis better. ⋯ Given the frequency of emesis, the potential that some portion of emesis may be related to care, and the adverse association between emesis and survival, approaches that treat or prevent emesis better may improve the chances of survival following out-of-hospital cardiac arrest.
