Resuscitation

In out-of-hospital cardiac arrest (OHCA) due to ventricular fibrillation (VF), VF may recur during resuscitation (recurrent VF) or fail to defibrillate (shock-resistant VF). While retrospective studies have suggested that amplitude spectral area (AMSA) and slope predict defibrillation, it is unknown whether the predictive power is influenced by VF type. We hypothesized that in witnessed OHCA with initial rhythm of VF that the utility for AMSA and slope to predict defibrillation would differ between shock-resistant and recurrent VF. ⋯ In witnessed OHCA with VF as initial rhythm, recurrent VF is associated with higher values of AMSA and slope and is likely to re-defibrillate. However, when VF is shock-resistant, AMSA and slope are highly predictive of defibrillation.

Comparative Study
Comparison of GlideScope(®) versus Macintosh laryngoscope for the removal of a hypopharyngeal foreign body: a randomized cross-over cadaver study.
This study aimed to evaluate whether GlideScope(®) is an effective and acceptable method for the removal of a hypopharyngeal foreign body. ⋯ In this cadaver model, the Macintosh laryngoscope appeared to be more efficient and preferred than GlideScope(®) for extracting hypopharyngeal airway foreign bodies that are associated with fatal asphyxiation.

To obtain an accurate audit during in-hospital cardiac arrest, following recommendations of the Utstein style and measuring time intervals between the different interventions, is difficult. ⋯ The audio recording system permits the register of a larger number of items per patient during in-hospital cardiac arrest and allows measurement of time intervals between the different interventions during cardiopulmonary resuscitation.
