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.

Induction of a shorter compression phase is correlated with a deeper chest compression during metronome-guided cardiopulmonary resuscitation: a manikin study.
Recent studies have shown that there may be an interaction between duty cycle and other factors related to the quality of chest compression. Duty cycle represents the fraction of compression phase. We aimed to investigate the effect of shorter compression phase on average chest compression depth during metronome-guided cardiopulmonary resuscitation. ⋯ Induction of a shorter compression phase is correlated with a deeper chest compression during metronome-guided cardiopulmonary resuscitation.

Randomized Controlled Trial
Utility of the Pentax-AWS in performing tracheal intubation while wearing chemical, biological, radiation and nuclear personal protective equipment: a randomised crossover trial using a manikin.
Following a chemical, biological, radiation and nuclear (CBRN) incident, prompt establishment of an advanced airway is required for patients with respiratory failure within the warm zone, while wearing personal protective equipment (PPE). Previous studies reported that intubation attempts were prolonged, and incidence of esophageal intubation was increased with conventional Macintosh laryngoscope (McL), while wearing CBRN-PPE. Pentax-AWS (AWS), a recently introduced portable video laryngoscope, was compared with the McL to test its utility for tracheal intubation while wearing CBRN-PPE. ⋯ Although the CBRN-PPE adversely affected time required to complete tracheal intubation with the AWS, suited intubations using the AWS were even superior to unsuited intubations using the McL. The AWS should be a promising device to perform tracheal intubation while wearing the CBRN-PPE.

Implementation of a novel communication tool and its effect on patient comprehension of care and satisfaction.
Emergency department (ED) communication has been demonstrated as requiring improvement and ED patients have repeatedly demonstrated poor comprehension of the care they receive. Through patient focus groups, the authors developed a novel tool designed to improve communication and patient comprehension. ⋯ Using their novel communication tool, the authors were not able to show a statistically significant improvement in either comprehension or satisfaction, though a tendency towards improved comprehension was seen.

Randomized Controlled Trial
Efficacy of the Disposcope endoscope, a new video laryngoscope, for endotracheal intubation in patients with cervical spine immobilisation by semirigid neck collar: comparison with the Macintosh laryngoscope using a simulation study on a manikin.
To evaluate whether endotracheal intubation in patients with cervical spine immobilisation by a semirigid neck collar is easier using the Disposcope endoscope (DE), a new video laryngoscope, than with the Macintosh laryngoscope (ML). ⋯ In patients with cervical spine immobilisation by a semirigid neck collar, the DE may be a more effective device for endotracheal intubation than the ML.
