Polytrauma

Nowadays, the tools available to assess the severity of a polytrauma patient in the pre-hospital setting (vital parameters, shock index, MGAP score, Vittel criteria) have their limitations and are sometimes subjective. To date, there are no objective, practical and reproducible tools for triaging these patients. Venous lactataemia also appears to be predictive of poor outcome in severe trauma. However, there are no studies in the literature on capillary lactataemia, which would indicate the potential severity of a polytrauma patient in the pre-hospital setting. However, it is an easily performed, risk-free assay, the results of which can be obtained rapidly at the scene of the accident. The aim of this project is to confirm that, like venous lactataemia, capillary lactataemia can be useful in the pre-hospital phase for predicting a patient's poor outcome. Incorporating this assay into the assessment of potentially severe polytrauma patients in the pre-hospital phase could improve the predictive value of clinical and contextual data and thus enable better referral and management of these patients.

dult patients with multiple traumatic injuries admitted to the ICU from the operating room, emergency department, or hospital wards who meet the study criteria will be included after obtaining informed consent from the patient or their legal guardian. Participants will be randomly divided into two groups: one group will receive treatment guided by the difference between carbon dioxide levels in venous and arterial blood, while the other group will receive treatment based on standard resuscitation parameters commonly used in critical care. As part of routine monitoring, all patients will have a central venous catheter and an arterial line inserted to measure blood parameters. Blood samples from both lines will be taken shortly after ICU admission and at regular intervals during the first three days. These samples will be analyzed using a bedside blood gas machine, and the results will be compared between the two groups to determine whether monitoring the difference in carbon dioxide levels between venous and arterial blood improves patient outcomes compared with standard care.

This study seeks to evaluate the feasibility of a Abdominal Aortic Balloon Occlusion of the Aorta (AAJT-S) in exanguinating trauma patients with non-compressible truncal haemorrhage in the emergency room and the pre-hospital setting.

Trauma is defined as a physical injury from an external source of sudden onset and severity, which require immediate medical attention. Polytrauma is a short verbal equivalent commonly used for severely injured patients usually with associated injury (i.e., two or more severe injuries in at least two different areas of the body), less often with a multiple injury (i.e., two or more severe injuries in one body area). Polytrauma patients usually have a much higher risk of mortalities and disabilities than the risk of expected mortalities in individual injuries patients. Despite improvements in trauma systems worldwide, trauma continues to be one of the leading causes of death and disability in all age groups, especially the young and middle age group. Approximately 5.8 million people die each year due to trauma related injuries, representing 8% of the worldwide mortality. For studying the outcomes of trauma, accurate and reliable methodological tools are required for appropriate scoring of severity and outcome prediction. Trauma scores were designed to facilitate the triage of patients in the Emergency Room (ER) and identify patients with Polytrauma with low chances of survival. Those scores were meant to organize and improve the quality of trauma care systems, and to assess resources allocation. Trauma patients present to the emergency department (ED) with a great variety of injuries and diseases. To address these, the Abbreviated Injury Scale (AIS) system defines the severity of injury throughout the different regions of the body. It is an anatomically based, consensus derived, global severity scoring system that classifies an individual injury by body region according to its relative severity on a 6-point scale (1 = minor and 6 = maximal). The system is constantly revised, expanded, and improved, and the Association for the Advancement of Automotive Medicine recently announced its latest revision, the AIS 2005-Update 2008 and AIS 2015. To summarize a single patient's multiple injures into a single score, the Injury Severity Score (ISS) was created by Baker et al. in 1974, which has been considered the "gold standard" among anatomic injury severity indicators. It is based on the AIS severity values, that is, the summation of the squares of the severity digit in the AIS of the most severe injuries, in three of six predefined body regions. However, the ISS only includes one injury in each body region, which leads to possible inclusion of a less severe injury in other body regions rather than another serious injury in the same body region. To overcome this limitation, a modified ISS, the New Injury Severity Score (NISS) was introduced by Osler et al. in 1997. NISS is simply the sum of squares of the three most severe injuries, regardless of the body regions injured. Further, Wang et al. have created the Exponential Injury Severity Score (EISS) in 2014 by modifying the AIS system. The EISS was computed as the simple change in AIS values by raising each AIS severity score (1-6) by 3 taking a power of AIS minus 2, and then summing the three most severe scores (i.e., highest AIS values), regardless of body regions. With this exponential transformation of the AIS values, the EISS is expected to be more reflective of the true severity of injuries in a patient with polytrauma. In Wang's study, the EISS is reported to be more predictive of survival; therefore, it might be used as the standard summary measure of human trauma.

Traumatic injuries, defined as a physical injury with sudden onset, are a leading cause to disability and impaired health. Persons who sustain a traumatic injury often report problems in daily life activities and reduced quality of life, which may limit participation in work/studies, leisure activities and family life. Consequently, complex rehabilitation and support is recommended in National Trauma guidelines due to the often long-lasting physical and psychological sequela of the injury. The main goal of this study is to determine the effectiveness of a self-management support program delivered to persons with a moderate or severe traumatic injury in the sub-acute phase of recovery (i.e. 3-4 months after injury). The self-management program aims to enhance patients' self-efficacy by building skills and self-management strategies to cope with injury-related consequences. The program has a group-based format and consists of eight sessions comprising psychoeducation, skill mastery and sharing of experiences. The participants who will be included in the study must be between 18 and 70 years, be residing in the southeast region of Norway, be admitted to Oslo University hospital or transferred from local hospital within 72 hours after injury, have at least a two-day hospital stay, and be able to read and understand Norwegian language. Participants will be randomly assigned to either intervention or control group. A group of patients will also be able to self-select if they want to receive the self-management support program or be in the control group. The latter is an explorative part of the study to evaluate the influence of patients' treatment-preferences on the study outcomes. Participants in the control group will receive treatment as usual.
