Eur J Trauma Emerg Surg 2024; 50:987-994. [PMID: 38300282 DOI: 10.1007/s00068-024-02463-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2023] [Accepted: 01/22/2024] [Indexed: 02/02/2024]
Abstract
PURPOSE Pre-hospital emergency anaesthesia is routinely used in the care of severely injured patients by pre-hospital critical care services. Anaesthesia, intubation, and positive pressure ventilation may lead to haemodynamic instability. The aim of this study was to identify the frequency of new-onset haemodynamic instability after induction in trauma patients with a standardised drug regime. METHODS A retrospective database analysis was undertaken of all adult patients treated by a physician-led urban pre-hospital care service over a 6-year period. The primary outcome measure was the frequency of new haemodynamic instability following pre-hospital emergency anaesthesia. The association of patient characteristics and drug regimes with new haemodynamic instability was also analysed. RESULTS A total of 1624 patients were included. New haemodynamic instability occurred in 231 patients (17.4%). Patients where a full-dose regime was administered were less likely to experience new haemodynamic instability than those who received a modified dose regime (9.7% vs 24.8%, p < 0.001). The use of modified drug regimes became more common over the study period (p < 0.001) but there was no change in the rates of pre-existing (p = 0.22), peri-/post-anaesthetic (p = 0.36), or new haemodynamic instability (p = 0.32). CONCLUSION New haemodynamic instability within the first 30 min following pre-hospital emergency anaesthesia in trauma patients is common despite reduction of sedative drug doses to minimise their haemodynamic impact. It is important to identify non-drug factors that may improve cardiovascular stability in this group to optimise the care received by these patients.

Abstract
Background Tiered trauma team activation (TTA) allows systems to optimally allocate resources to an injured patient. Target undertriage and overtriage rates of <5% and <35% are difficult for centers to achieve, and performance variability exists. The objective of this study was to optimize and externally validate a previously developed hospital trauma triage prediction model to predict the need for emergent intervention in 6 hours (NEI-6), an indicator of need for a full TTA. Methods The model was previously developed and internally validated using data from 31 US trauma centers. Data were collected prospectively at five sites using a mobile application which hosted the NEI-6 model. A weighted multiple logistic regression model was used to retrain and optimize the model using the original data set and a portion of data from one of the prospective sites. The remaining data from the five sites were designated for external validation. The area under the receiver operating characteristic curve (AUROC) and the area under the precision-recall curve (AUPRC) were used to assess the validation cohort. Subanalyses were performed for age, race, and mechanism of injury. Results 14 421 patients were included in the training data set and 2476 patients in the external validation data set across five sites. On validation, the model had an overall undertriage rate of 9.1% and overtriage rate of 53.7%, with an AUROC of 0.80 and an AUPRC of 0.63. Blunt injury had an undertriage rate of 8.8%, whereas penetrating injury had 31.2%. For those aged ≥65, the undertriage rate was 8.4%, and for Black or African American patients the undertriage rate was 7.7%. Conclusion The optimized and externally validated NEI-6 model approaches the recommended undertriage and overtriage rates while significantly reducing variability of TTA across centers for blunt trauma patients. The model performs well for populations that traditionally have high rates of undertriage. Level of evidence 2.

Abstract
INTRODUCTION Traumatic Thoracic Aortic Injury (TTAI) is associated with high mortality rates and is the second leading cause of death in traumatic patients. There has been a considerable advancement in the management of TTAI with novel and improved surgical procedures and imaging modalities. The aim of this study was to determine the national demographic and regional trends in mortality associated with TTAI in the United States across twenty years, 1999 to 2019. METHODS The multiple cause of death data on Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research (CDC-WONDER) database was utilized to query death certificates for TTAI from 1999 to 2019, in the United States. The International Classification of the Diseases, Tenth Revision (ICD-10) code S25.0 was used to identify and abstract data for TTAI related deaths. The data was further abstracted based on age, race, gender and Census-Bureau defined regions. The age-adjusted mortality rate (AAMR) per 100,000 population-year and Average Annual Percentage Change (AAPC) with 95 % Confidence Interval were computed. The JoinPoint software was utilized to compute the temporal trends in mortality based on a segmented change and AAPC calculation. RESULTS A total of 20,842 TTAI associated deaths occurred from 1999 to 2019 corresponding to an AAMR of 0.407(0.401-0.412) per 100,000 population-year. The overall AAMR reduced from 0.759 to 0.223 per 100,000 population-year from 1999 to 2019[average APC -6.5(-7.5; -5.5)]. The reduction was reported in both <45 age group [average APC -6.5(-7.9; -5.1)] and >45 age group [-6.2(-7.3; -5.0)]; among females [average APC -6.1(-7.8; -4.3)] and males [-6.1(-7.2; -5.0)]; among Whites [average APC -6.9(-7.8; -5.9)] and Blacks [-5.0(-7.4; -2.5)]. The reduction in mortality as per the census region was highest in the west followed by Mid-West, North-East and South [average APC -6.8(-8.6; -5.0); -6.2(-8.8; -3.6); -5.7(-7.0; -4.4); -5.5(-7.4; -3.6), respectively]. CONCLUSION There was a significant decrease in the TTAI associated mortality trends in the United States across 1999-2019 with a consistent decline in all demographic and regional subgroups.

Abstract
BACKGROUND During the prehospital phase, paramedics consider patients' condition according to illness, injury, disease and decide on transport to an appropriate hospital according to severity. This can affect patient survival and treatment prognosis, because despite intervention at this early stage, problems such as incorrect triage of severity and inappropriate hospital selection may occur, indicating a need for improvement in the process. PURPOSE The aim of this review is to identify the overall trend of research conducted on prehospital triage by analyzing the emergency medical services system and presenting future studies to practitioners and researchers. METHODS A scoping review was conducted of existing literature on research trends in relation to prehospital triage. The studies reviewed were identified using electronic databases such as PubMed, CINAHL, Cochrane Library, Web of Science, and Scopus. RESULTS Ninety-eight documents were finally selected and analyzed that focused on prehospital triage status, process accuracy, tools, guidelines, and protocols. CONCLUSION Research is proposed that focuses on various non-traumatic patient types, prehospital triage education, and development of training programs to reduce errors in the emergency patient handover process between prehospital and hospital health professionals and to improve patient health and quality of life.

Abstract
BACKGROUND The ageing population is requiring more ambulance attendances for falls. This scoping review aimed to map and synthesise the evidence for the prehospital management of Emergency Medical Services (EMS) attended adult patients who fall. METHODS The Joanna Briggs Institute methods for scoping reviews were used. Six databases were searched (Medline, Scopus, CINAHL, Cochrane, EMBASE, ProQuest), 1st August 2021. Included sources reported: ambulance attended (context), adults who fell (population), injuries, interventions or disposition data (concept). Data were narratively synthesised. RESULTS One-hundred and fifteen research sources met the inclusion criteria. Detailed information describing prehospital delivered EMS interventions, transport decisions and alternative care pathways was limited. Overall, adults< 65 years were less likely than older adults to be attended repeatedly and/or not transported. Being male, falling from height and sustaining severe injuries were associated with transport to major trauma centres. Older females, falling from standing/low height with minor injuries were less likely to be transported to major trauma centres. CONCLUSION The relationship between patient characteristics, falls and resulting injuries were well described in the literature. Other evidence about EMS management in prehospital settings was limited. Further research regarding prehospital interventions, transport decisions and alternative care pathways in the prehospital setting is recommended.

Abstract
Background
Thoracic trauma is a major cause of death in trauma patients and road traffic accident (RTA)-related thoracic injuries have different characteristics than those with non-RTA related thoracic traumas, but this have been poorly described. The main objective was to investigate the epidemiology, injury pattern and outcome of patients suffering a significant RTA-related thoracic injury. Secondary objective was to investigate the influence of serious thoracic injuries on mortality, compared to other serious injuries.
Methods
We performed a multicenter observational study including patients of the Rhône RTA registry between 1997 and 2016 sustaining a moderate to lethal (Abbreviated Injury Scale, AIS≥2) injury in any body region. A subgroup (AISThorax≥2 group) included those with one or more AIS≥2 thoracic injury. Descriptive statistics were performed for the main outcome and a multivariate logistic regression was computed for our secondary outcome.
Results
A total of 176,346 patients were included in the registry and 6,382 (3.6%) sustained a thoracic injury. Among those, median age [IQR] was 41 [25–58] years, and 68.9% were male. The highest incidence of thoracic injuries in female patients was in the 70–79 years age group, while this was observed in the 20–29 years age group among males. Most patients were car occupants (52.3%). Chest wall injuries were the most frequent thoracic injuries (62.1%), 52.4% of which were multiple rib fractures. Trauma brain injuries (TBI) were the most frequent concomitant injuries (29.1%). The frequency of MAISThorax = 2 injuries increased with age while that of MAISThorax = 3 injuries decreased. A total of 16.2% patients died. Serious (AIS≥3) thoracic injuries (OR = 12.4, 95%CI [8.6;18.0]) were strongly associated with mortality but less than were TBI (OR = 27.9, 95%CI [21.3;36.7]).
Conclusion
Moderate to lethal RTA-related thoracic injuries were rare. Multiple ribs fractures, pulmonary contusions, and sternal fractures were the most frequent anatomical injuries. The incidence, injury pattern and mechanisms greatly vary across age groups.

El-Akkawi AI, de Paoli FV, Andersen G, Højsgaard A, Christensen TD. A case of severe flail chest with several dislocated sterno-chondral fractures. Int J Surg Case Rep 2019; 65:52-56. [PMID: 31689628 PMCID: PMC6838885 DOI: 10.1016/j.ijscr.2019.10.043] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2019] [Revised: 10/19/2019] [Accepted: 10/22/2019] [Indexed: 11/27/2022] Open
Abstract
Surgical stabilization of flail chest lead to fast weaning from mechanical ventilation. Plates can be used for stabilization of sterno-costal dehiscence. Cartilage reconstruction of a CT scan can reveal the true severity of the trauma.
Introduction Flail chest is diagnosed clinically by the presence of paradox movement of a segment of the thoracic wall during spontaneous breathing. Radiographic finding confirming a clinical flail chest are fractures of three or more consecutive ribs or costal cartilages in two or more places. Surgical stabilization is associated with a reduced length of hospital stay, time with mechanical ventilation and risk of respiratory complications. Presentation of case A trauma patient had a Computed Tomography (CT) scan showing multiple costa fractures, sternal fracture, manubrium fracture, sternal displacement and dehiscence of the sternal-costal attachment. The severity of the trauma was visualized after performing a cartilage reconstruction of the trauma CT scan. The patient underwent surgery, using fixation plates to stabilize the thoracic cage, and was then weaned quickly from mechanical ventilation. Discussion This case indicates, that if a patient has a severe flail chest recognized clinically, but not radiologically, a reconstruction of cartilage can reveal the true severity of the trauma. Indeed, the patient in this case experienced a positive outcome from surgery. However, such a procedure demands correct timing and experience in surgical stabilization of the thoracic wall. Furthermore, the injury required accurate planning with the involved personal before surgery. Conclusion Surgical stabilization of advanced flail chest with concomitant sternal fracture, seems to be a safe procedure, that might reduce the need of mechanical ventilation and the length of stay at the Intensive Care Unit (ICU). Furthermore, cartilage reconstruction of the trauma CT scan can potentially identify a severe flail chest, that might be missed on regular 3D bone reconstruction.
