Randomized Controlled Trial
Ethyl chloride spray, a local anesthetic in arterial blood gas sampling: A randomized, controlled, double-blinded study.
Arterial blood gas sampling provides useful information on respiratory parameters and acid-base balance. However, this procedure is painful and uncomfortable for the patient. Therefore, this study aimed to examine the analgesic efficacy of ethyl chloride spray compared to a placebo during radial artery blood gas sampling. ⋯ Ethyl chloride spray has analgesic efficacy in arterial blood gas sampling. Therefore, the use of this spray provides an analgesic effect on patients during arterial blood gas sampling performed in the emergency department.

Randomized Controlled Trial
Effects of vertical compression during pediatric cardiopulmonary resuscitation using the one-handed chest compression technique.
The posture of the rescuer while performing the one-handed chest compression (OHCC) has not yet been evaluated. This study aimed to investigate the effect of vertical compression during pediatric cardiopulmonary resuscitation (CPR) using the OHCC technique. ⋯ The vertical OHCC could provide a deeper and more adequate CCD compared with the conventional OHCC, and the advantages of the vertical OHCC originate from the superiority of the compression force.

Randomized Controlled Trial
Randomized trial of three airway management techniques for restricted access in a simulated pediatric scenario.
Emergency pediatric airway management during restricted access to the head is challenging and may relate to an entrapped motor vehicle trauma. Video laryngoscopy and supraglottic airways have separately been described to facilitate face-to-face airway management. We hypothesized that video laryngoscopy might be superior to direct laryngoscopy or supraglottic device use to establish ventilation during face-to-face airway management, studied in a simulated pediatric entrapped motor vehicle scenario. ⋯ All three techniques have high success rates. Time to establish ventilation with the SGD was significantly faster compared to DL and VL and participants rated SGD easiest to use. The utility of VL was limited due to significantly longer time to ventilation, despite significantly improved view compared to DL, similar to adult studies. Since time and success are clinically important, this study suggests that supraglottic devices should be considered for primary emergency pediatric airway management in situations with restricted access to the head.
