The major components affecting high quality cardiopulmonary resuscitation (CPR) have been defined as the ability of the rescuer, hand position, position of the rescuer and victim, depth and rate of chest compressions, and fatigue. Until now, there have been no studies on dominant versus non-dominant hand position and the rescuer's side of approach. This study was designed to evaluate the effectiveness of hand position and approach side on the quality of CPR between right-handed (RH) and left-handed (LH) novice rescuers. ⋯ The performance of novice rescuers during chest compressions is influenced by the position of the dominant hand and the rescuer's side of approach. In CPR training and real world situations, a novice rescuer, regardless of handedness, should consider hand positions for contacting the sternum identical to the side of approach after approaching from the nearest and most accessible side, for optimal CPR performance.

Ultrasonography is becoming increasingly common in the diagnosis of fracture in emergency medicine. The aim of our study was to investigate the diagnostic accuracy of sonographic examinations for diagnosing fifth metacarpal fractures. ⋯ Sonographic examination can be used as an effective diagnostic tool in patients with fifth metacarpal trauma.

In 2009 the Wellington Free Ambulance implemented an education programme to reduce high concentration oxygen delivery to patients with an acute exacerbation of chronic obstructive pulmonary disease (AECOPD). The aim of this audit was to compare pre-hospital oxygen delivery to patients with AECOPD before and after the programme. ⋯ The proportion of patients administered supplemental high concentration oxygen therapy markedly decreased between 2005 and 2010 following implementation of the education programme. However, in 2010 more than half of the patients not managed with high concentration oxygen therapy were still exposed to high concentration oxygen through the use of oxygen-driven nebulisers. To reduce exposure to high concentration oxygen in AECOPD the use of air-driven nebulisers or metered dose inhalers with spacers is required.

This study presents the findings of a nationwide study of acute pesticide poisoning (APP) outcomes, including outcome predictors such as physician and hospital volume and associated factors. ⋯ In APP patients, treatment by a high-volume physician can reduce LOS and treatment cost.
