Participation in a simulation-based team training educational intervention significantly improved surrogate measures of clinical performance, time to initiation of key clinical tasks, and teamwork during simulated pediatric resuscitation. A positive correlation between clinical and teamwork performance suggests that effective teamwork improves clinical performance of resuscitation teams.

J Neurophysiol 113: 2500 -2510, 2015. First published February 4, 2015 doi:10.1152/jn.00849.2014.-Dopamine is now well established as a modulator of locomotor rhythms in a variety of developing and adult vertebrates. However, in mice, while all five dopamine receptor subtypes are present in the spinal cord, it is unclear which receptor subtypes modulate the rhythm. Dopamine receptors can be grouped into two families-the D 1/5 receptor group and the D 2/3/4 group, which have excitatory and inhibitory effects, respectively. Our data suggest that dopamine exerts contrasting dose-dependent modulatory effects via the two receptor families. Our data show that administration of dopamine at concentrations Ͼ35 M slowed and increased the regularity of a locomotor rhythm evoked by bath application of 5-hydroxytryptamine (5-HT) and N-methyl-D(L)-aspartic acid (NMA).This effect was independent of the baseline frequency of the rhythm that was manipulated by altering the NMA concentration. We next examined the contribution of the D 1 -and D 2 -like receptor families on the rhythm. Our data suggest that the D 1 -like receptor contributes to enhancement of the stability of the rhythm. Overall, the D 2 -like family had a pronounced slowing effect on the rhythm; however, quinpirole, the D 2 -like agonist, also enhanced rhythm stability. These data indicate a receptor-dependent delegation of the modulatory effects of dopamine on the spinal locomotor pattern generator. dopamine; locomotion; monoamine; spinal cord NEURAL CIRCUITS that produce basic rhythmic motor patterns of locomotion, in vertebrates, reside primarily in the spinal cord and are subject to neuromodulation from a wide range of sources both intrinsic and extrinsic to the spinal cord (Dunbar et al.

Team SA involves a common perspective between two or more individuals regarding current environmental events, their meaning, and projected future status. Team SA has been theorized to be important for resuscitation team effectiveness. Accordingly, multidimensional frameworks of observable behaviors relevant to resuscitation teams are needed to understand more deeply the nature of team SA, its implications for team effectiveness, and whether it can be trained. A seven-dimension team resuscitation SA framework was developed following a literature review and consensus process using a modified Delphi approach with a group of content experts. We applied a pre-post design within a day-long team training program involving four video-recorded simulated resuscitation events and 42 teams across Canada. The first and fourth events represented “pre” and “post” training events, respectively. Teams were scored on SA five times within each 15-minute event. Distractions were introduced to investigate whether SA scores would be affected. The current study provides initial construct validity evidence for a new measure of SA and explicates SA's role in resuscitation teams.

The reluctance of resuscitation teams to appropriately challenge the incorrect order resulted in a high rate of inappropriate medication administration. The rate of teams following the incorrect order was significantly associated with poor challenging of the incorrect order and the hierarchical demeanor of the perceived authority figure. Institution-based factors may impact this rate of incorrect medication administration.
