Hospital is a stressful place of employment, and a high proportion of healthcare workers, especially the ICU (Intensive Care Unit) nurses were found to be at risk of PTSD. Previous studies showed that taxing working memory through visuospatial tasks during the reconsolidation process of aversive memories can reduce the number of intrusions afterwards. However, the finds could not be replicated by some researches, indicating there may be some boundary conditions that are subtle and complex.
We performed a randomized controlled trial (ChiCTR2200055921; URL: www.chictr.org.cn). In our study, a series of ICU nurses or probationers who performed a cardiopulmonary resuscitation (CPR) were enrolled and instructed to play a visuospatial music tapping game ("Ceaseless Music Note", CMN; Beijing Muyuan Technology Co., Ltd., Beijing, China) at the fourth day after CPR. The numbers of intrusions each day were recorded from the first to the seventh days (24 h×6 day), and the vividness and emotionality of CPR memories were rated at the 4th and 7th days. These parameters were compared between different groups (game with background sound; game with sound off; sound only; none).
The game-matching background music can have an add-on effect for single tapping game with no sound in reducing the emotionality of previous aversive memories.
We proposed that flow experience (the subjective experience of effortless attention, reduced self-awareness, and enjoyment, and may be induced by optimal skill-demands compatibility in challenging tasks) as a key boundary condition for successful reconsolidation intervention.

医院是一个充满压力的工作场所，研究发现，很大一部分医护人员，尤其是重症监护病房（ICU）护士有患创伤后应激障碍（PTSD）的风险。先前的研究表明，在厌恶记忆的重新巩固过程中，通过视觉空间任务加重工作记忆负担，可以减少之后的侵入性记忆数量。然而，一些研究无法重复这些发现，这表明可能存在一些微妙而复杂的边界条件。
我们进行了一项随机对照试验（ChiCTR2200055921；网址：www.chictr.org.cn）。在我们的研究中，招募了一系列实施过心肺复苏（CPR）的ICU护士或见习护士，并指导他们在心肺复苏后的第四天玩一款视觉空间音乐敲击游戏（“无尽音符”，CMN；北京沐源科技有限公司，中国北京）。记录从第一天到第七天（24小时×6天）每天的侵入性记忆数量，并在第4天和第7天对心肺复苏记忆的生动程度和情感强度进行评分。对不同组（有背景声音的游戏组；关闭声音的游戏组；仅有声音组；无处理组）的这些参数进行比较。
游戏匹配的背景音乐对于无声的单次敲击游戏在降低先前厌恶记忆的情感强度方面具有附加效果。
我们提出，心流体验（一种轻松专注、自我意识降低和愉悦的主观体验，可能由具有挑战性任务中的最佳技能需求兼容性所诱发）是成功进行重新巩固干预的关键边界条件。
