fluid resuscitation and trauma

INTRODUCTION: Coagulopathy associated with isolated traumatic brain injury (C-iTBI) is a frequent complication associated with poor outcomes, primarily due to its role in the development or progression of haemorrhagic brain lesions. The independent risk factors for its onset are age, severity of traumatic brain injury (TBI), volume of fluids administered during resuscitation, and pre-injury use of antithrombotic drugs. Although the pathophysiology of C-iTBI has not been fully elucidated, two distinct stages have been identified: an initial hypocoagulable phase that begins within the first 24 h, dominated by platelet dysfunction and hyperfibrinolysis, followed by a hypercoagulable state that generally starts 72 h after the trauma...

Blunt abdominal injury with pelvic fracture is common in polytrauma cases and is a major challenge for emergency physicians. Fluid resuscitation and massive transfusion protocol should be activated when pelvic fracture patients are found in hypovolemic shock. At the emergency department, resuscitative endovascular balloon occlusion of the aorta may be performed to temporarily control bleeding. Finally, a damage control operation or trans-arterial embolization may be performed in the hybrid operating room.

INTRODUCTION: While intravenous fluid therapy is essential to re-establishing volume status in children who have experienced trauma, aggressive resuscitation can lead to various complications. There remains a lack of consensus on whether pediatric trauma patients will benefit from a liberal or restrictive crystalloid resuscitation approach and how to optimally identify and transition between fluid phases. METHODS: A panel was comprised of physicians with expertise in pediatric trauma, critical care, and emergency medicine...

BACKGROUND: The use of intravenous fluid therapy in patients with major trauma in prehospital settings is still controversial. We conducted an umbrella review to evaluate which is the best volume expansion in the resuscitation of a hemorrhagic shock to support the development of major trauma guideline recommendations. METHODS: We searched PubMed, Embase, and CENTRAL up to September 2022 for systematic reviews (SRs) investigating the use of volume expansion fluid on mortality and/or survival...

BACKGROUND: Mesenchymal stromal cells (MSCs) have shown promising therapeutic options for acute lung injury (ALI) caused by multiple factors. Here, we evaluated the therapeutic potential of adipose tissue-derived mesenchymal stromal cells (ADSCs) in trauma and hemorrhagic shock (THS)-induced ALI. METHODS: ALI model induced by THS was constructed by fractures plus abdominal trauma plus acute hemorrhage plus fluid resuscitation. The ADSCs group rats were generated by injecting 2 × 106 ADSCs at 0 and 1 h after THS...

INTRODUCTION: Predicting which patients with acute circulatory failure will respond to the fluid by an increase in cardiac output is a daily challenge. End-expiratory occlusion test (EEOT) and mini-fluid challenge (MFC) can be used for assessing fluid responsiveness in patients with spontaneous breathing activity, cardiac arrhythmias, low-tidal volume and/or low lung compliance. METHODS: The objective of the study is to evaluate the value of EEOT and MFC-induced rise in left ventricular outflow tract (LVOT) velocity time integral (VTI) in predicting fluid responsiveness in acute circulatory failure in comparison to the passive leg-raising (PLR) test...

INTRODUCTION AND IMPORTANCE: Penetrating cardiac injury is rare and historically known to have very poor prognosis. Even today, 90 % of patients die before arriving to hospital. Even though patient presentations can be atypical, organized timely intervention can lead to survival. CASE REPORT: A 21 years old arrived 5 h after stab injury to right anterior chest. He was hypotensive with a sucking wound bleeding on his right chest as well as hemothorax on the same side...

BACKGROUND: Intravenous (IV) fluid therapy is essential in the treatment of critically ill pediatric surgery and trauma patients. Recent studies have suggested that aggressive fluids may be detrimental to patients. Prospective studies are needed to compare liberal to restricted fluid management in these patients. The primary objective of this pilot trial is to test study feasibility-recruitment and adherence to the study treatment algorithm. METHODS: We conducted a two-part pilot randomized controlled trial (RCT) comparing liberal to restricted crystalloid fluid management in 50 pediatric post-operative (1-18 years) and trauma (1-15 years) patients admitted to our pediatric intensive care unit (PICU)...

BACKGROUND: The increase in firearm injuries at U.S. pediatric trauma centers is a national public health crisis. This spike in penetrating trauma has challenged even the most mature pediatric trauma centers. OBJECTIVE: This project aims to identify U.S. pediatric trauma center best practices for the evaluation and resources dedicated to pediatric firearm injuries. METHODS: This study used an exploratory cross-sectional survey design using a study-specific questionnaire...

INTRODUCTION: Intraosseous (IO) infusion, the pressurized injection of fluids into bone through a catheter, is a life-preserving resuscitative technique for treating trauma patients with severe hemorrhage. However, little is known regarding the application times, placement accuracy, and end-user ratings of battery-powered and manual IO access devices. This study was specifically designed to fill these knowledge gaps on six FDA-approved IO access devices. MATERIALS AND METHODS: Three experienced U...

Background: We aimed to characterize the temporal trends of crystalloid resuscitation in severely injured trauma patients after intensive care unit (ICU) admission. Using 500 mL/hr of crystalloid in the first 6 hours of ICU admission to distinguish early versus late resuscitation, we hypothesized early resuscitation was associated with less volume by 48 hours and better outcomes compared with late resuscitation. Methods: We performed a retrospective review of the trauma registry of a high-volume level 1 academic trauma center to examine adult trauma patients admitted to the ICU (2016-2019) with : with initial serum lactate ≥ 4 mmol/dL, elevated lactate (≥ 2 mmol/L) at ICU admission, and lactate normalization within 48 hours...

BACKGROUND: The open abdomen is an innovation that greatly improved surgical understanding of damage control, temporary abdominal closure, staged abdominal reconstruction, viscera and enteric fistula care, and abdominal wall reconstruction. This article provides an evidence-informed, expert, comprehensive narrative review of the open abdomen in trauma, acute care, and vascular and endovascular surgery. METHODS: A group of 12 international trauma, acute care, and vascular and endovascular surgery experts were invited to review current literature and important concepts surrounding the open abdomen...

BACKGROUND: Pediatric trauma triage and transfer decisions should incorporate the likelihood that an injured child will require pediatric trauma center (PTC) resources. Resource utilization may be a better basis than mortality risk when evaluating pediatric injury severity. However, there is currently no consensus definition of PTC resource utilization that encompasses the full scope of PTC services. METHODS: Consensus criteria were developed in collaboration with the Pediatric Trauma Society (PTS) Research Committee using a modified Delphi approach...

PURPOSE: The purpose of this study was to identify predictive factors for peri-pelvic vascular injury in patients with pelvic fractures and to incorporate these factors into a pelvic vascular injury score (P-VIS) to detect severe bleeding during the prehospital trauma management. METHODS: To identify potential predictive factors, data were taken (1) of a Level I Trauma Centre with 467 patients (ISS ≥ 16 and AISPelvis  ≥ 3)...

Cardiac tamponade is a leading cause of death in blunt thoracic trauma. Ultrasound improved the recognition of cardiac tamponade and therefore has a vital role in acute critical situations in the Emergency Department and in the Intensive Care Unit. Besides recognition of cardiac tamponade, treatment protocols are important. In trauma patients with hemodynamic stable cardiac tamponade, time should be taken for a proper workup for an explorative sternotomy. In hemodynamic unstable trauma patients, the pericardium should be drained, and fluid resuscitation should be performed followed by emergency sternotomy...

If a trauma (or infection) exceeds the body's evolutionary design limits, a stress response is activated to quickly restore homeostasis. However, when the injury severity score is high, death is often imminent. The goal of this review is to provide an update on the effect of small-volume adenosine, lidocaine and Mg2+ (ALM) therapy on increasing survival and blunting secondary injury after non-compressible hemorrhagic shock and other trauma and infective/endotoxemic states. Two standout features of ALM therapy are: (1) resuscitation occurs at permissive hypotensive blood pressures (MAPs 50-60 mmHg), and (2) the drug confers neuroprotection at these low pressures...

BACKGROUND Surgical management in patients who undergo traumatic blood loss but who refuse blood transfusion can be challenging, but physicians and surgeons must comply with the wishes and beliefs of their patients. This report describes the management of severe anemia, with hemoglobin level of 2.5 g/dL, in a 71-year-old male Korean trauma patient who declined blood transfusion. CASE REPORT A 71-year-old man was admitted to hospital with severe blood loss following trauma. He declined blood transfusion due to his religious belief as a Jehovah's Witness...

PURPOSE: The inability to achieve primary fascial closure (PFC) after emergency laparotomy increases the rates of adverse outcomes including fistula formation, incisional hernia, and intraabdominal infection. Hypertonic saline (HTS) infusion improves early PFC rates and decreases time to PFC in patients undergoing damage control laparotomy (DCL) after injury. We hypothesized that in patients undergoing DCL after penetrating abdominal injury, HTS infusion would decrease the time to fascial closure as well as the volume of crystalloid required for resuscitation without inducing clinically relevant acute kidney injury (AKI) or electrolyte derangements...

The endothelium is lined by a protective mesh of proteins and carbohydrates called the endothelial glycocalyx (EG). This layer creates a negatively charged gel-like barrier between the vascular environment and the surface of the endothelial cell. When intact the EG serves multiple functions, including mechanotransduction, cell signaling, regulation of permeability and fluid exchange across the microvasculature, and management of cell-cell interactions. In trauma and/or hemorrhagic shock, the glycocalyx is broken down, resulting in the shedding of its individual components...

Patients with traumatic brain injury (TBI) or head trauma present challenges for emergency physicians and neurosurgeons. Traumatic brain injury is currently a community health issue. For the best possible care, it is crucial to understand the various helpful therapy techniques in the pre-operative and pre-hospital phases. The initial rapid infusion of large volumes of mannitol and a hypertonic crystalloid solution to restore blood pressure and blood volume is the current standard of care for people with combined hemorrhagic shock (HS) and traumatic brain injury...
