Successful management of battlefield traumatic cardiac arrest using the abdominal aortic and junctional tourniquet (AAJT): A case series

Abstract: The Russo-Ukrainian war's prolonged warfare, resource constraints, and extended evacuation times have forced significant adaptations in Ukraine's medical system - including technological advancements and strategic resource placement. This study examined if the Abdominal Aortic and Junctional Tourniquet - Stabilized (AAJT-S) could manage traumatic cardiac arrest (TCA) at forward surgical stabilization sites (FSSS) as an adjunct to damage control surgery. Six patients in severe hypovolemic shock presented at an FSSS during fighting in Bakhmut (July 2022) and Slovyansk (May 2023). Following TCA due to exsanguination, the AAJT-S was applied 2cm below the umbilicus. Cardiopulmonary resuscitation (CPR) and transfusion (blood and/or plasma) were initiated. All six patients were resuscitated. None required vasopressor support post-resuscitation. Five survived to the next level of care. One died awaiting evacuation, and another of wounds after 10 days. Four survived to discharge. Three were followed and neurologically intact, and no death records matched the fourth's name and date of birth at 18 months. Follow-up was limited, but one patient was neurologically intact at one year. The AAJT-S effectively resuscitated TCA patients. It increased mean arterial pressure, focused resuscitative efforts on the upper torso, simplified care, and preserved crucial field resources. An alternative to traditional emergency thoracotomy, AAJT-S could replace or complement resuscitative endovascular balloon occlusion of the aorta in pre-hospital settings, given its ease of application by combat medics. AAJT-S, alongside blood transfusion and CPR, achieved 100% success in return of spontaneous circulation and effectively managed TCA in a wartime FSSS.

    Identifying opioid relapse during COVID-19 using natural language processing of nationwide Veterans Health Administration electronic medical record data

    Abstract: Novel and automated means of opioid use and relapse risk detection are needed. Unstructured electronic medical record data, including written progress notes, can be mined for clinically relevant information, including the presence of substance use and relapse-critical markers of risk and recovery from opioid use disorder (OUD). In this study, we used natural language processing (NLP) to automate the extraction of opioid relapses, and the timing of these occurrences, from veteran patients' electronic medical record. We then demonstrated the utility of our NLP tool via analysis of pre-/post-COVID-19 opioid relapse trends among veterans with OUD. For this demonstration, we analyzed data from 107,606 veterans OUD enrolled in Veterans Health Administration, comparing a pandemic-exposed cohort (n = 53,803; January 2019-March 2021) to a matched prepandemic cohort (n = 53,803; October 2017-December 2019). The recall of our NLP tool was 75% and our precision was 94%, demonstrating moderate sensitivity and excellent specificity. Using the NLP tool, we found that the odds of opioid relapse postpandemic onset were proportionally higher compared to prepandemic trends, despite patients having fewer mental health encounters from which to derive instances of relapse postpandemic onset. In this research application of the tool, and as hypothesized, we found that opioid relapse risk was elevated postpandemic. The application of NLP Methods: to identify and monitor relapse risk holds promise for future surveillance, risk prevention, and clinical outcome research.
