The need for novel strategies to address postoperative pain associated with cardiac surgery: A commentary and introduction to "SMArTVIEW"

Effects of virtual reality on chest tube removal pain management in patients undergoing coronary artery bypass grafting: a randomized clinical trial

The pain associated with chest tube removal (CTR) is one of the significant complications of cardiac surgery. The management of this pain is recognized as a vital component of nursing care. The application of distraction techniques using virtual reality (VR) is an effective and straightforward non-pharmacological approach to alleviate pain. This study aimed to determine the impact of VR technology on the management of pain caused by CTR following coronary artery bypass grafting (CABG). This randomized clinical trial was conducted on 70 patients undergoing CABG at Imam Reza and Qaem hospitals in Mashhad, Iran, in 2020. The patients were randomly divided into two groups of 35. For the intervention group, a 360-degree video was played using VR glasses 5 min before the CTR procedure. The pain intensity was measured before, immediately after, and 15 min after CTR, using the Visual Analogue Scale. Also, the Depression Anxiety and Stress Scale-21 (DASS-21), and the Rhoten Fatigue Scale (RFS) were used to evaluate intervention and control groups before the CTR procedure. The collected data was analyzed using statistical tests, such as Chi-square, independent t-test, and Mann-Whitney test. The patients were homogeneous in terms of stress, anxiety, and fatigue levels before CTR, and they did not show any significant differences (P > 0.05). The average pain intensity score of patients in the intervention group significantly decreased immediately and 15 min after CTR, compared to the control group (P < 0.001). Given the positive impact of VR distraction on the severity of pain associated with CTR in patients undergoing CABG, this technique can serve as an effective, accessible, and cost-efficient non-pharmacological approach for managing pain in these patients.Trial registration: This study was registered in the Iranian Registry of Clinical Trials (code: IRCT20190708044147N1; approval date, 08/26/2019).

[Application possibilities of digital tools in postoperative pain therapy]

BACKGROUND

Recently, digital tools, such as smartphone-based applications and the use of artificial intelligence have increasingly found their way into pain medicine. This could enable new treatment approaches in postoperative pain management. Therefore, this article provides an overview of various digital tools and their potential application options in postoperative pain management.

MATERIAL AND METHODS

An orienting literature search was carried out in the MEDLINE and Web of Science databases, and a targeted selection of essential key publications was made in order to provide a structured presentation of different current possible applications and a discussion based on the most recent knowledge.

RESULTS

Today, possible applications of digital tools, even if they mostly have only a model character, include pain documentation and assessment, patient self-management and education, pain prediction, decision support for medical staff, and supportive pain therapy, for example in the form of virtual reality and videos. These tools offer advantages such as individualized treatment concepts, addressing specific patient groups, reduction of pain and analgesics, and the potential for early warning or detection of postoperative pain. Furthermore, the challenges of the technical implementation and appropriate user training are highlighted.

CONCLUSION

The use of digital tools, although so far integrated in clinical routine in a relatively selective and exemplary manner, promises to be an innovative approach for personalized postoperative pain therapy in the future. Future studies and projects should help to integrate the promising research approaches into everyday clinical practice.
