Previous experience with simulated pediatric cardiac arrests (that is, mock codes) suggests frequent deviation from American Heart Association (AHA) basic and advanced life support algorithms. During highly infectious outbreaks, acute resuscitation scenarios may also increase the risk of insufficient personal protective equipment (PPE) use by health care workers (HCWs). Simulation was used as an educational tool to measure adherence with PPE use and pediatric resuscitation guidelines during simulated cardiopulmonary arrests of 2009 influenza A patients.
A retrospective, observational study was performed of 84 HCWs participating in 11 in situ simulations in June 2009. Assessment included (1) PPE adherence, (2) confidence in PPE use, (3) elapsed time to specific resuscitation maneuvers, and (4) deviation from AHA guidelines.
Observed adherence with PPE use was 61% for eye shields, 81% for filtering facepiece respirators or powered air-purifying respirators, and 87% for gown/gloves. Use of a "gatekeeper" to control access and facilitate donning of PPE was associated with 100% adherence with gown and respirator precautions and improved respirator adherence. All simulations showed deviation from pediatric basic life support protocols. The median time to bag-valve-mask ventilation improved from 4.3 to 2.7 minutes with a gatekeeper present. Rapid isolation carts appeared to improve access to necessary PPE. Confidence in PPE use improved from 64% to 85% after the mock code and structured debriefing.
Large gaps exist in the use of PPE and self-protective behaviors, as well as adherence to resuscitation guidelines, during simulated resuscitation events. Intervention opportunities include use of rapid isolation measures, use of gatekeepers, reinforcement of first responder roles, and further simulation training with PPE.
以往模拟小儿心脏骤停(即模拟急救)的经验表明,常与美国心脏协会(AHA)的基础和高级生命支持算法存在偏差。在高传染性疫情期间,急性复苏场景也可能增加医护人员个人防护装备(PPE)使用不足的风险。模拟被用作一种教育工具,以衡量在对2009年甲型流感患者进行模拟心肺复苏期间,PPE使用和儿科复苏指南的遵守情况。
对2009年6月参与11次现场模拟的84名医护人员进行了一项回顾性观察研究。评估内容包括:(1)PPE的遵守情况;(2)使用PPE的信心;(3)特定复苏操作的用时;(4)与AHA指南的偏差。
观察到眼罩的PPE遵守率为61%,过滤式面罩呼吸器或动力空气净化呼吸器为81%,隔离衣/手套为87%。使用“把关人”来控制进入并协助穿戴PPE与隔离衣和呼吸器预防措施方面100%的遵守率以及呼吸器遵守情况的改善相关。所有模拟均显示与儿科基础生命支持方案存在偏差。在有把关人的情况下,球囊面罩通气的中位时间从4.3分钟缩短至2.7分钟。快速隔离推车似乎改善了获取必要PPE的便利性。在模拟急救和结构化汇报后,使用PPE的信心从64%提高到了85%。
在模拟复苏事件期间,PPE的使用、自我保护行为以及对复苏指南的遵守方面存在很大差距。干预机会包括使用快速隔离措施、使用把关人、强化急救人员的角色以及进一步进行PPE模拟培训。
