To determine if a real-time audiovisual link with a neonatologist, termed video-assisted resuscitation or VAR, improves provider performance during a simulated neonatal resuscitation scenario.
Using high-fidelity simulation, 46 study participants were presented with a neonatal resuscitation scenario. The control group performed independently, while the intervention group utilized VAR. Time to effective ventilation was compared using Wilcoxon rank sum tests. Providers' use of the corrective steps for ineffective ventilation per the NRP algorithm was compared using Cochran-Armitage trend tests.
The time needed to establish effective ventilation was significantly reduced in the intervention group when compared to the control group (mean time 2 min 42 s versus 4 min 11 s, p<0.001). In the setting of ineffective ventilation, only 35% of control subjects used three or more of the first five corrective steps and none of them used all five steps. Providers in the control group most frequently neglected to open the mouth and increase positive pressure. In contrast, all of those in the intervention group used all of the first five corrective steps, p<0.001. All participants in the control group decided to intubate the infant to establish effective ventilation, compared to none in the intervention group, p<0.001.
Using VAR during a simulated neonatal resuscitation scenario significantly reduces the time to establish effective ventilation and improves provider adherence to NRP guidelines. This technology may be a means for regional centers to support local providers during a neonatal emergency to improve patient safety and improve neonatal outcomes.
确定与新生儿科医生的实时视听连接(称为视频辅助复苏或VAR)是否能在模拟新生儿复苏场景中提高医护人员的表现。
采用高保真模拟,向46名研究参与者呈现新生儿复苏场景。对照组独立进行操作,而干预组使用VAR。使用Wilcoxon秩和检验比较建立有效通气的时间。使用Cochran-Armitage趋势检验比较医护人员根据新生儿复苏项目(NRP)算法对无效通气采取纠正措施的情况。
与对照组相比,干预组建立有效通气所需的时间显著缩短(平均时间2分42秒对4分11秒,p<0.001)。在通气无效的情况下,对照组中只有35%的受试者在前五个纠正步骤中使用了三个或更多步骤,且无人使用全部五个步骤。对照组的医护人员最常忽略的是张开婴儿口腔并增加正压。相比之下,干预组的所有人员都使用了前五个纠正步骤,p<0.001。对照组的所有参与者都决定对婴儿进行插管以建立有效通气,而干预组无人这样做,p<0.001。
在模拟新生儿复苏场景中使用VAR可显著缩短建立有效通气的时间,并提高医护人员对NRP指南的依从性。这项技术可能是区域中心在新生儿紧急情况期间支持当地医护人员以提高患者安全性和改善新生儿结局的一种手段。
