Randomized Controlled Trial Comparative Study Clinical Trial
A randomised comparison of three laryngoscopes with the Macintosh.
The Macintosh laryngoscope blade was compared with three modified blades--the Bizzarri-Giuffrida, the 'Improved Vision' Macintosh, and the Wiemers blade. Before and after a training session 24 participants intubated a Laerdal Airway Management Trainer with the four blades in random order. Intubation time was measured, oesophageal malpositions and 'clicks' indicating possible teeth damage, were counted. ⋯ In regard to the intubation time before training (P < 0.02), the intubation time after training (P < 0.003), and handling (P < 0.0005), the Bizzarri-Giuffrida was significantly inferior to the Macintosh. The 'Improved Vision' Macintosh and the Wiemers were not significantly different to the Macintosh. No significant difference was seen for oesophageal malpositioning and 'clicks' between any of the blades.

Randomized Controlled Trial Clinical Trial
Active compression-decompression cardiopulmonary resuscitation: a population-based, prospective randomised clinical trial in out-of-hospital cardiac arrest.
Different mechanical devices have been developed to improve cardiopulmonary resuscitation (CPR). The aim of this study was to evaluate active compression-decompression (ACD) CPR applied by Emergency Medical Service (EMS) in a defined population. The Trondheim region EMS (population 154,000) employs simultaneous paramedic and physician response. ⋯ This is the largest, single-centre, randomised, population based study of ACD CPR in out-of-hospital cardiac arrest to date. Even when considering a wider outcome spectrum than crude survival, we found no evidence of clinical benefit. In a quarter of cases ACD CPR was inapplicable, further limiting its potential usefulness.
