PREHOSP EMERG CARE 2024:1-24. [PMID: 39387678 DOI: 10.1080/10903127.2024.2413876] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2024] [Accepted: 09/30/2024] [Indexed: 10/15/2024]
Abstract
Entrapped patients may be simply entombed or experiencing crush injury or entanglement. Patients with trauma who are entrapped are at higher risk of significant injury than patients not entrapped. Limited access and prolonged scene times further complicate patient management. Although patient entrapment is a significant focus of specialty teams, such as urban search & rescue (US&R) teams that operate as local, regional, and/or national resources in response to complex scenes and disaster scenarios, entrapment is a regular occurrence in routine EMS response. Therefore, all EMS clinicians must have the training and skills to manage entrapped patients and to support medically-directed rescue throughout the extrication process.NAEMSP recommends:EMS clinicians must perform a timely and thorough primary and secondary assessment and reassessments in parallel with dynamic extrication planning; the environment may require adaption of standard assessment techniques and devices.EMS clinicians should establish early, clear, and ongoing communications with rescue personnel to ensure a coordinated patient-centered medically directed approach to extrication. Communication with the patient should be frequent, clear, and reassuring.EMS clinicians should immediately take measures to effectively prevent and manage hypothermia.EMS clinicians should recognize airway management in the entrapped patient is always challenging. When required, advanced airway placement should be performed by the most experienced operator with proficiency in multiple modalities and alternative techniques in limited access situations.In entrapped patients who are experiencing or are at risk for crush syndrome, EMS clinicians should initiate large-volume (i.e., 1-1.5 liters/hour for adults and 20 milliliters/kilogram/hour for pediatric patients for the initial 3-4 hours) fluid resuscitation with crystalloid, preferably normal saline, as early as possible and prior to extrication.In entrapped patients who are experiencing or are at risk for crush syndrome, EMS clinicians should administer medications to mitigate risks of hyperkalemia, infection, and renal failure, early and prior to extrication.Tourniquet application should be considered in the setting of the crushed extremity as a potential adjunct to medical optimization before extrication of some patients.Patients with prolonged entrapment with the potential for severe injuries require complex resuscitation and may benefit from EMS physician management on scene. EMS systems should consider an early EMS physician response to entrapped patients.

Abstract
A serious kind of fractured foot ailment is a foot crush injury. Foot injury commonly happens in accidents involving transportation or the workplace, such as automobile accidents, big objects falling on the foot, or heavy machinery running over the foot. Foot crush injuries are more severe than regular foot fractures. These wounds are usually very serious, involving many fractures and soft tissue injuries. The main symptoms include pain, severe muscle and tissue damage, and extreme swelling. Because of this, treating a foot crush injury can be quite challenging and frequently requires the collaboration of physical therapists, orthopedic surgeons, and podiatrists. Physiotherapy is important for reducing pain, increasing range of motion, strengthening muscles, and improving leg function. It also decreases the chance of contractures, deformities, and stiffness following crush injuries. In this report, we present the case of a 58-year-old male with a lacerated wound over his left foot with chief complaints of severe pain. Patient-tailored physiotherapy rehabilitation, including active movements, passive movements, isometric exercises, and a strengthening regimen consisting of numerous repetitions and progressive complexity, was given. At the end of four weeks, the patient had improved strength and quality of life.

Abstract
Severe traumatic injury leads to marked systemic inflammation and multiorgan injury. Endogenous drivers such as extracellular nucleic acid may play a role in mediating innate immune response and the downstream pathogenesis. Here, we explored the role of plasma extracellular RNA (exRNA) and its sensing mechanism in inflammation and organ injury in a murine model of polytrauma. We found that severe polytrauma-bone fracture, muscle crush injury, and bowel ischemia-induced a marked increase in plasma exRNA, systemic inflammation, and multiorgan injury in mice. Plasma RNA profiling with RNA sequencing in mice and humans revealed a dominant presence of miRNAs and marked differential expression of numerous miRNAs after severe trauma. Plasma exRNA isolated from trauma mice induced a dose-dependent cytokine production in macrophages, which was almost abolished in TLR7-deficient cells but unchanged in TLR3-deficient cells. Moreover, RNase or specific miRNA inhibitors against the selected proinflammatory miRNAs (i.e., miR-7a-5p, miR-142, let-7j, miR-802, and miR-146a-5p) abolished or attenuated trauma plasma exRNA-induced cytokine production, respectively. Bioinformatic analyses of a group of miRNAs based on cytokine readouts revealed that high uridine abundance (>40%) is a reliable predictor in miRNA mimic-induced cytokine and complement production. Finally, compared with the wild-type, TLR7-knockout mice had attenuated plasma cytokine storm and reduced lung and hepatic injury after polytrauma. These data suggest that endogenous plasma exRNA of severely injured mice and ex-miRNAs with high uridine abundance prove to be highly proinflammatory. TLR7 sensing of plasma exRNA and ex-miRNAs activates innate immune responses and plays a role in inflammation and organ injury after trauma.

Abstract
INTRODUCTION Primary disasters may result in mass casualty events with serious injuries, including crush injury and crush syndrome. OBJECTIVE This narrative review provides a focused overview of crush injury and crush syndrome for emergency clinicians. DISCUSSION Millions of people worldwide annually face natural or human-made disasters, which may lead to mass casualty events and severe medical issues including crush injury and syndrome. Crush injury is due to direct physical trauma and compression of the human body, most commonly involving the lower extremities. It may result in asphyxia, severe orthopedic injury, compartment syndrome, hypotension, and organ injury (including acute kidney injury). Crush syndrome is the systemic manifestation of severe, traumatic muscle injury. Emergency clinicians are at the forefront of the evaluation and treatment of these patients. Care at the incident scene is essential and focuses on treating life-threatening injuries, extrication, triage, fluid resuscitation, and transport. Care at the healthcare facility includes initial stabilization and trauma evaluation as well as treatment of any complication (e.g., compartment syndrome, hyperkalemia, rhabdomyolysis, acute kidney injury). CONCLUSIONS Crush injury and crush syndrome are common in natural and human-made disasters. Emergency clinicians must understand the pathophysiology, evaluation, and management of these conditions to optimize patient care.

Abstract
BACKGROUND Acute compartment syndrome (ACS) is characterised by abnormal pressure inside a compartment, resulting in ischemia of muscles and nerves. Most orthopaedic surgeons, especially those who work in major trauma centres, have been or will be facing a case of ACS in their clinical activity. Fortunately, complications related to untreated compartment syndrome have become less frequent thanks to a better understanding of pathogenesis and to early recognition and prompt surgical treatment. The aim of this study is to identify the existing evidence regarding aetiology of trauma-related ACS of the leg. METHODS A systematic review of the literature was undertaken using PubMed Medline, Ovid Medline and the Cochrane library, extended by a manual search of bibliographies. Retrieved articles were eligible for inclusion if they reported data about aetiology of trauma-related compartment syndrome of the tibia. RESULTS Ninety-five studies that fulfilled the inclusion criteria were identified. By dividing the studies into three groups according to the traumatic aetiology, we were able to classify traumatic ACS as fracture related, soft tissue injury related and vascular injury related. Fracture related was the most represented group, comprising 58 papers, followed by the soft tissue injury related group which includes 44 articles and vascular injury related group with 24 papers. CONCLUSIONS Although traditionally ACS has been associated mainly with fractures of tibial diaphysis, literature demonstrates that other localisations, in particular in the proximal tibia, are associated with an increased incidence of this serious condition. The forms of ACS secondary to soft tissues injuries represent an extremely variable spectrum of lesions with an insidious tendency for late diagnosis and consequently negative outcomes. In the case of vascular injury, ACS should always be carefully considered as a priority, given the high incidence reported in the literature, as a result of primitive vascular damage or as a result of revascularisation of the limb. Knowledge of aetiology of this serious condition allows us to stratify the risk by identifying a population of patients most at risk, together with the most frequently associated traumatic injuries.

Abstract
BACKGROUND Few guidelines exist for the initial management of wounds in disaster settings. As wounds sustained are often contaminated, there is a high risk of further complications from infection, both local and systemic. Healthcare workers with little to no surgical training often provide early wound care, and where resources and facilities are also often limited, and clear appropriate guidance is needed for early wound management. METHODS We undertook a systematic review focusing on the nature of wounds in disaster situations, and the outcomes of wound management in recent disasters. We then presented the findings to an international consensus panel with a view to formulating a guideline for the initial management of wounds by first responders and subsequent healthcare personnel as they deploy. RESULTS We included 62 studies in the review that described wound care challenges in a diverse range of disasters, and reported high rates of wound infection with multiple causative organisms. The panel defined a guideline in which the emphasis is on not closing wounds primarily but rather directing efforts toward cleaning, debridement, and dressing wounds in preparation for delayed primary closure, or further exploration and management by skilled surgeons. CONCLUSION Good wound care in disaster settings, as outlined in this article, can be achieved with relatively simple measures, and have important mortality and morbidity benefits.

Abstract
Hyperbaric oxygen therapy has been approved for primary or adjunctive care in 14 indications. A hyperbaric environment exists when a patient's whole body is physically exposed to 100% oxygen and pressure that is greater than one atmosphere absolute. Hyperbaric oxygen therapy works through the ideal gas laws and is effective as an adjunctive therapy in the treatment of crush injuries. Oxygen is considered a drug and can have contraindications and adverse effects. Hyperbaric therapy works through several different mechanisms in the crush injury. Effects of hyperoxygenation, reduction of edema, infection control enhancement, blood vessel and collagen formation, and reduction of free radicals and reperfusion injury help in healing in patient with crush injuries.

Abstract
Explosions remain the leading cause of death and injury to combatants in conflict. The current ‘Global War on Terror’ has resulted in a shift of explosive-related injuries from the battlefield into civilian centres. Despite musculoskeletal injuries being the most common injury witnessed in blast, there remains little research into the effects of blast on this system. In order to develop new treatment regimens and mitigation systems, there is a requirement to have a better understanding of skeletal trauma in this unique environment. The aim of this review article is to deconstruct the complex injury mechanisms witnessed in blast and relate them to its effects on the musculoskeletal system.
