Comparative Study
A comparison of autopsy detected injuries in a porcine model of cardiac arrest treated with either manual or mechanical chest compressions.
The objective of this study was to evaluate and compare the complications of cardiopulmonary resuscitation after manual or mechanical chest compressions in a swine model of ventricular fibrillation. In this retrospective study, 106 swine were treated with either manual (n=53) or mechanical chest compressions with the LUCAS device (n=53). All swine cadavers underwent necropsy. ⋯ Nine animals in the manual, and two in the LUCAS group had liver hematomas (P=0.026%). In the manual group, eight animals were detected with spleen hematomas whereas no such injury was identified in the LUCAS group (P=0.003). LUCAS devise minimized the resuscitation-related trauma compared with manual chest compressions in a swine model of cardiac arrest.

Randomized Controlled Trial Comparative Study
Comparison of GlideScope video laryngoscope and intubating laryngeal mask airway with direct laryngoscopy for endotracheal intubation.
The aim of this study was to determine whether GlideScope video laryngoscope (GVL) and intubating laryngeal mask airway (i-LMA) improve the intubation success rate and could be easily learned and performed by paramedic students when compared with the direct laryngoscopic (DL) method. The study was designed as a prospective randomized crossover trial that included 121 paramedic students. All participants were asked to intubate each Ambu Airway Management Trainer manikins after the lecture and demonstration. ⋯ Success rates of i-LMA and GVL were significantly higher compared with DL (P=0.005 and P=0.006, respectively). No significant difference was determined between i-LMA and GVL in terms of successful intubation (P>0.05). This study showed that GVL and i-LMA provided better intubation success rates and were easier for paramedic students when compared with the classic DL method.

Comparative Study
Accuracy of prehospital triage of trauma patients by emergency physicians: a retrospective study in western Switzerland.
Accurate identification of major trauma patients in the prehospital setting positively affects survival and resource utilization. Triage algorithms using predictive criteria of injury severity have been identified in paramedic-based prehospital systems. Our rescue system is based on prehospital paramedics and emergency physicians. The aim of this study was to evaluate the accuracy of the prehospital triage performed by physicians and to identify the predictive factors leading to errors of triage. ⋯ Physicians using clinical judgement provide effective prehospital triage of trauma patients. Only a few factors predicting errors in triage process were identified in this study.

Comparative Study
Interrater agreement: a comparison between two emergency department triage scales.
The aim was to elucidate if, by strictly applying the Adaptive Process Triage (ADAPT) scale, the interrater agreement increased among the participating registered nurses (RNs) than when triaging according to the older scale, which allowed subjective interpretations of signs and symptoms. ⋯ Both the triage scales showed moderate overall agreements, while dispersion of triage decisions across several triage levels declined when ADAPT was used. Although the algorithm for acuity allocation by ADAPT seemed well defined, many patient scenarios were triaged as both unstable and stable and thus allocated to various triage levels. If ADAPT is to function as a safe triage tool with low interrater variability, further revision of the triage algorithms is needed.
