Randomized Controlled Trial
Emergency cricothyroidotomy performed by inexperienced clinicians--surgical technique versus indicator-guided puncture technique.
To improve the ease and safety of cricothyroidotomy especially in the hand of the inexperienced, new instruments have been developed. In this study, we compared a new indicator-guided puncture technique (PCK) with standard surgical technique (ST) regarding success rate, performance time and complications. ⋯ In this human cadaver study the PCK technique produced more major complications and more failures than the ST. In the hand of the inexperienced operator the standard surgical approach seems to be a safe procedure, which can successfully be performed within an adequate time. The PCK technique cannot be recommended for inexperienced operators.

Randomized Controlled Trial
Efficacy of metronome sound guidance via a phone speaker during dispatcher-assisted compression-only cardiopulmonary resuscitation by an untrained layperson: a randomised controlled simulation study using a manikin.
Untrained laypersons should perform compression-only cardiopulmonary resuscitation (COCPR) under a dispatcher's guidance, but the quality of the chest compressions may be suboptimal. We hypothesised that providing metronome sounds via a phone speaker may improve the quality of chest compressions during dispatcher-assisted COCPR (DA-COCPR). ⋯ Metronome sound guidance during DA-COCPR for the untrained bystanders improved the chest compression rates, but was associated more with shallow compressions than the conventional DA-COCPR in a manikin model.
