BACKGROUND: Every year up to 35,000 people in Germany are severely injured in accidents in traffic, during work or leisure activities. The 24-h availability of the trauma room as well as surgical and intensive care unit capacities are essential to provide optimal acute care. This study analyzed the frequency of utilization of the resource trauma room in a level I trauma center in the past. METHODS: Data of a level I trauma center from 2005 to 2016 including trauma room alerts deployed by the rescue coordination center and the number of patients found to be severely injured (ISS ≥ 16) during trauma room diagnostics were analyzed retrospectively...

BACKGROUND: Currently no drug therapy prevents secondary injury progression after TBI. Our aim was to investigate the effects of small-volume intravenous adenosine, lidocaine and Mg (ALM) resuscitation fluid after moderate-TBI in a rat fluid-percussion injury model. METHODS: Anesthetized, mechanically-ventilated male Sprague-Dawley rats (449±5g) were randomly assigned to one of four groups: 1) Sham (craniotomy without TBI), 2) No-Treatment, 3) Saline-controls or 4) ALM therapy (all n=16)...

BACKGROUND: The Train the Trainer (TTT) model is increasingly used in limited resource settings as a mechanism to disseminate resuscitation knowledge and skills among providers. Anecdotally, however, many resuscitation programs that use this model fail to achieve sustainability. OBJECTIVE: We aim to systematically review the literature to describe the evidence for the TTT method of knowledge dissemination for resuscitation courses in limited resource settings. METHODS: We conducted a systematic review of the literature in accordance with PRISMA guidelines of the PubMed, Cochrane Library, MEDLARS online (MEDLINE), and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases...

BACKGROUND: Coagulopathy and inflammation induced by hemorrhagic shock and traumatic injury are associated with increased mortality and morbidity. Vitamin C (VitC) is an antioxidant with potential protective effects on the pro-inflammatory and pro-coagulant pathways. We hypothesized that high-dose VitC administered as a supplement to fluid resuscitation would attenuate inflammation, coagulation dysfunction, and end-organ tissue damage in a swine model of polytrauma and hemorrhage. METHODS: Male Sinclair swine (n = 24; mean body weight 27 kg) were anesthetized, intubated, mechanically ventilated, and instrumented for physiological monitoring...

PURPOSE: Central venous catheter insertion for acute trauma resuscitation may be associated with mechanical complications, but studies on the exact central venous catheter tip positions are not available. The goal of the study was to analyze central venous catheter tip positions using routine emergency computed tomography. METHODS: Consecutive acute multiple trauma patients requiring large-bore thoracocervical central venous catheters in the resuscitation room of a university hospital were enrolled retrospectively from 2010 to 2015...

BACKGROUND: Trauma is the leading cause of death and disability in patients aged 1-46 y. Severely injured patients experience considerable blood loss and hemorrhagic shock requiring treatment with massive transfusion of red blood cells (RBCs). Preclinical and retrospective human studies in trauma patients have suggested that poorer therapeutic efficacy, increased severity of organ injury, and increased bacterial infection are associated with transfusion of large volumes of stored RBCs, although the mechanisms are not fully understood...

Background: The genus Mycobacterium has an ability to persist in hostile environments for years before its reactivation in favorable conditions. The major bottleneck in decades of mycobacterial research is a poor understanding of molecular mechanism which assists bacteria to attain dormancy and reactivation later. Methods: In this study, hydroxyl radical was quantified in aerobically growing mycobacterial cells using 2-deoxy-D-ribose assay. Furthermore, extraneous addition of hydroxyl radical in Wayne's dormancy model induced reactivation of dormant cells...

Good-quality chest compressions improve outcomes in cardiac arrest. While manual chest compressions are suboptimal in this regard, the LUCAS device has been shown to improve the effectiveness of chest compressions during cardiopulmonary resuscitation (CPR). The complication rate associated with mechanical CPR, however, has not been adequately studied. Limited evidence suggests no difference in internal injury between manual and mechanical CPR. We report the case of a patient on anticoagulation who developed a mediastinal hematoma post mechanical CPR and on whom subtle findings on initial echocardiography could have alerted the clinician to this complication early during the clinical course...

Invasive electrophysiology (EP) mapping and catheter ablation has increasingly become the standard of care for many cardiac arrhythmias like supraventricular tachycardias, atrial fibrillation, premature ventricular complexes (PVC), and monomorphic ventricular tachycardia. In this review, we discuss the recent progress made in the mapping and ablation of ventricular fibrillation (VF). Ventricular activation during VF is apparently disorganized, making mapping and interpretation difficult. Prolonged mapping during VF would require mechanical circulatory support as VF causes complete hemodynamic collapse...

BACKGROUND: Bone cement implantation syndrome is a known complication causing mortality during perioperative period particularly in patients with malignancy. With rise in aging population with malignancy in low income country, the syndrome is more likely to be encountered. CASE PRESENTATION: We present a case of 66 years old male patient with metastatic bronchogenic carcinoma of lung with pathological proximal femur fracture of left hip that underwent a cemented endoprosthesis under combined spinal epidural anesthesia who succumbed to intraoperative mortality due to grade III bone cement implantation syndrome even after aggressive fluid resuscitation, vasopressor use, and mechanical ventilation...

BACKGROUND: Glibenclamide (GBC) improves neurological outcome after cardiac arrest (CA) in rats. In this study, we sought to elucidate the mechanism responsible for the neuroprotective effects of GBC by using a high-field MRI system. METHODS: Male Sprague-Dawley rats were subjected to 10-min asphyxial CA followed by cardiopulmonary resuscitation (CPR). Diffusion-weighted imaging (DWI) as well as conventional T2-weighted imaging was conducted prior to CA and at 24, 48, and 72 h after resuscitation...

Fifty years after the first successful heart transplantation, despite multiple advances in the treatment of advanced acute and chronic heart failure, there is still no equivalent to heart transplantation as a long-term treatment for end-stage heart failure. Transplantation is, however, limited by the scarcity and quality of heart allografts. Donors are nowadays significantly older, particularly in European countries, and traumatic head injury as the cause of death has been replaced by intracerebral hemorrhage or hypoxic brain damage in the majority of cases...

Major hemorrhage is a significant contributor to the morbidity and mortality resulting from traumatic injury. In addition to its role in in early mortality, hemorrhagic shock followed by resuscitation (HS/R) is known to initiate immunological events which contribute to the development of organ dysfunction. The pathogenesis of acute lung injury following HS/R involves macrophage activation. Recent studies have shown that macrophage function may in part be regulated by polarization towards classical M1 pro-inflammatory cells or alternatively activated anti-inflammatory M2 cells...

OBJECTIVE: Most deaths occur in the pre-hospital setting, whereas mortality in the emergency department (ED) is low (<1%). However, our clinical impression is that some patients are being transported to hospital in devastating conditions with no likelihood of survival, but demanding extensive hospital resources. The decision on whether to transport a dying person to hospital or not is a difficult task for emergency medical services (EMS) personnel. As there is little epidemiological data about these patients, this paper aims to describe this special population...

Trauma with hypovolemic shock is an extreme pathological state that challenges the body to maintain blood pressure and oxygenation in the face of hemorrhagic blood loss. In conjunction with surgical actions and transfusion therapy, survival requires the patient's blood to maintain hemostasis to stop bleeding. The physics of the problem are multiscale: (a) the systemic circulation sets the global blood pressure in response to blood loss and resuscitation therapy, (b) local tissue perfusion is altered by localized vasoregulatory mechanisms and bleeding, and (c) altered blood and vessel biology resulting from the trauma as well as local hemodynamics control the assembly of clotting components at the site of injury...

AIMS: Currently, the decision to initiate extracorporeal life support for patients who suffer cardiac arrest due to accidental hypothermia is essentially based on serum potassium level. Our goal was to build a prediction score in order to determine the probability of survival following rewarming of hypothermic arrested patients based on several covariates available at admission. METHODS: We included consecutive hypothermic arrested patients who underwent rewarming with extracorporeal life support...

There is growing awareness of the need for advance care planning in patients with chronic obstructive pulmonary disease (COPD). However, do-not-resuscitate (DNR) order implementation remains a challenge in clinical practice. We retrospectively analysed an observational cohort of 569 COPD patients with 2.5-8 years of follow-up in secondary care, to evaluate potential determinants and the prognostic significance of DNR order implementation and specification. 345 patients (61%) had no DNR order, of whom 27% died during a median (interquartile range (IQR)) follow-up of 1935 (1290-2448) days...
