Randomized Controlled Trial
Effects of resuscitation guideline terminology on pediatric cardiopulmonary resuscitation.
This study aimed to investigate the effect of resuscitation guideline terminology on pediatric cardiopulmonary resuscitation (CPR) performance. ⋯ Average CCD during simulated pediatric CPR according to the CCD target of '5 cm' was significantly lower than those according to the CCD target of 'at least one third of the anterior-posterior dimension of the chest'.

Retromolar intubation with video intubating stylet in difficult airway: A randomized crossover manikin study.
Difficult airway situations, such as trismus and neck rigidity, may prohibit standard midline orotracheal intubation. An alternative route of intubation from the retromolar space using a fiberoptic scope or rigid intubation stylet has been reported. There is no study investigating the applicability of retromolar intubation using a video intubating stylet. This study comparatively analyzed difficult airway management using a video intubating stylet in the retromolar and standard midline approaches. ⋯ The retromolar approach for intubation using a video intubating stylet may be a promising choice for selected patients with a combination of difficult airway features such as limited mouth opening, neck rigidity, and edematous tongue.

Performance comparison of intraosseous devices and setups for infusion of whole blood in a cadaveric swine bone model.
Intraosseous (IO) access can provide a critical bridge for blood product infusion when peripheral venous access is not obtainable. Successful pressurized IO infusion requires flow rates sufficient to preserve life, but with infusion pressures low enough to avoid clinical complications (e.g., hemolysis, bone damage, fat emboli). However, the optimal method for pressured IO delivery of blood was unknown. ⋯ Some pressured IO infusion methods can achieve flow rates adequate to serve as a resuscitative bridge in the massively hemorrhaged trauma victim, but flow rates and pressures vary greatly across IO pressurized infusion methods. Manual Rapid Infuser and push-pull methods conferred high flow rates but also relatively high pressures, highlighting the importance of using in vivo models in future research to assess the possible clinical complications of using these promising methods. Combined, present findings highlight the importance of studying pressurized IO methods towards preserving the life of the critically injured trauma victim.

Randomized Controlled Trial Multicenter Study
Comparison of Vie Scope® and Macintosh laryngoscopes for intubation during resuscitation by paramedics wearing personal protective equipment.
Endotracheal intubation (ETI) is still the gold standard of airway management, but in cases of sudden cardiac arrest in patients with suspected SARS-CoV-2 infection, ETI is associated with risks for both the patient and the medical personnel. We hypothesized that the Vie Scope® is more useful for endotracheal intubation of suspected or confirmed COVID-19 cardiac arrest patients than the conventional laryngoscope with Macintosh blade when operators are wearing personal protective equipment (PPE). ⋯ The use of the Vie Scope® laryngoscope in OHCA patients improved the first attempt success rate, and reduced intubation time compared to Macintosh laryngoscope in paramedics wearing PPE for against aerosol generating procedures.

Effect of age on the efficacy of tranexamic acid: An analysis of heterogeneity of treatment effect within the CRASH-2 dataset.
Trauma is a major cause of morbidity and mortality in older adults and will become more common as the population ages. Tranexamic acid (TXA) is a lysine analogue frequently used in the setting of significant trauma with hemorrhage. The aim of this study is to investigate the heterogeneity of treatment effect of TXA as it relates to patient age during trauma care. ⋯ Mortality related to trauma increases with age, however, there does not appear to be heterogeneity of treatment effect for TXA administration among different age groups.
