BACKGROUND: We endeavored to develop clinically translatable nonhuman primate (NHP) models of severe polytraumatic hemorrhagic shock. METHODS: NHPs were randomized into five severe pressure-targeted hemorrhagic shock (PTHS) ± additional injuries scenarios: 30-min PTHS (PTHS-30), 60-min PTHS (PTHS-60), PTHS-60 + soft tissue injury (PTHS-60+ST), PTHS-60+ST + femur fracture (PTHS-60+ST+FF), and decompensated PTHS+ST+FF (PTHS-D). Physiologic parameters were recorded and blood samples collected at five time points with animal observation through T = 24 h...

BACKGROUND Overall, life expectancy at the age of 80 has significantly increased in the industrialized world and the proportion of this age class undergoing cardiac surgery has also grown. In this context, we have analyzed a contemporary series of octogenarians undergoing mitral valve surgery at our institution. MATERIAL AND METHODS We performed a retrospective analysis of 138 consecutive octogenarians receiving mitral valve surgery between January 2006 and April 2017. Preoperative comorbidities, early mortality, postoperative clinical course, and predictors of mortality were examined...

OBJECTIVE: Surgical therapy for refractory primary cardiogenic shock is largely based on emergent placement of extracorporeal membrane oxygenation or short-term ventricular assist devices. We have adopted a strategy of routine implantation of durable left ventricular assist devices (LVAD) as initial therapy for refractory cardiogenic shock, in patients who are potential candidates for heart transplantation, and report our experience. METHODS: Retrospective review of 43 consecutive patients with refractory shock caused by acute myocardial infarction (n = 21) or acute decompensated heart failure (n = 22) who were treated with primary implantation of a durable LVAD in a single institution...

Inappropriate implantable cardiac defibrillator (ICD) shocks are associated with significant morbidity and have the potential to trigger ventricular arrhythmias, cardiac decompensation, and death. We present a case of multiple inappropriate ICD therapies in rapid succession due electromagnetic interference from a Dr-Ho's transcutaneous electric nerve stimulator machine, and subsequently from a faulty electrical outlet.

Background: Carvedilol is used in the management of hypertension, ischemic heart disease, heart failure and most recently, portal hypertension. It has been associated with improved outcomes regarding variceal bleeding, hepatic decompensation and death when compared to propranolol and endoscopic band ligation. The main cause of portal hypertension is cirrhosis and therefore carvedilol is increasingly used in these patients. Due to its extensive hepatic metabolism, carvedilol is contraindicated in severe hepatic impairment...

Aim: Adrenal insufficiency (AI) in cirrhosis is an issue that has recently gained momentum. It can be seen in both stable and critically ill (sepsis, septic shock, and gastrointestinal system bleeding) cirrhotic patients. Its prevalence exists in a wide range since standardization of diagnostic methods is lacking. We aimed to scrutinize this issue in a 108 case series. Materials and methods: We studied the presence of AI and its stage in patients with cirrhosis and its complications by using cross-sectional study...

Severe trauma initiates a systemic inflammatory cascade and that involves early activation of complement and cleavage of C5 into C5a (anaphylatoxin) and C5b (C5b-9 membrane attack complex). We examined activation of C5 in non-human primate (NHP) models of hemorrhagic shock. Blood plasma concentrations of C5b-9 were significantly increased in NHPs in response to hemorrhage alone and were further increased with the addition of tissue trauma. The onset of increased C5 cleavage was accelerated in NHPs that experienced decompensated poly-traumatic hemorrhagic shock...

Background and Objective: Dengue infection has evolved into an epidemic during last few years in Pakistan and has been associated with poor outcomes. Literature with respect to mortality risk factors in Dengue infection is not sufficient. This compelled us to conduct this study to find out major contributory factors to death in patients with dengue viral infection at one of Asia's ancient hospital setting with an aim to recognize complications at earliest and improve case management in future...

PURPOSE: Our primary aim was to identify predictors of immediate hemodynamic decompensation during the peri-intubation period. METHODS: We conducted a nested case-control study of a previously identified cohort of adult patients needing intubation admitted to a medical-surgical ICU during 2013-2014. Hemodynamic derangement was defined as cardiac arrest and/or the development of systolic blood pressure <90mmHg and/or mean arterial pressure <65mmHg 30min following intubation...

BACKGROUND: Pulmonary embolism can be difficult to diagnose, particularly in those who are hemodynamically unstable and cannot be imaged to confirm the diagnosis. Echocardiography can allow for rapid assessment of patients in shock, but requires adequate transthoracic windows to obtain clinically useful information. Emergency physician-performed transesophageal echocardiography (TEE) may be a useful tool when transthoracic echocardiography fails. CASE REPORT: An 86-year-old woman presented to the emergency department after a fall at home...

Septic shock is a life-threatening condition that occurs when the blood pressure drops to a low level after an infection. Atrial fibrillation (AF) is the most common arrhythmia to complicate its course. Beta (β)-blockers are often administrated to manage supraventricular tachyarrhythmias observed in patients presenting with sepsis. A 74-year-old woman presenting with sepsis demonstrated AF tachycardia characterised by severe hypotension. She was refractory to conventional therapy including verapamil and digoxin; therefore, treatment using landiolol (an ultrashort-acting β-blocker) was initiated...

Arginine vasopressin (AVP), a hormone secreted by the posterior pituitary, plays a vital role in maintaining vasomotor tone during acute blood loss. We hypothesized that decompensated hemorrhagic shock is associated with decreased AVP stores and supplementation during resuscitation would improve both blood pressure and renal function. Using a decompensated hemorrhagic shock model, male Long-Evans rats were bled to mean arterial blood pressure (MAP) of 40mmHg and maintained until the MAP could not be sustained without fluid...

Circulatory shock remains a leading cause of death in both military and civilian trauma. Early, accurate and reliable prediction of decompensation is necessary for the most efficient interventions and clinical outcomes. Individual tolerance to reduced central blood volume can serve as a model to assess the sensitivity and specificity of vital sign measurements. The compensatory reserve (CRM) is the measurement of this capacity. Measurements of muscle oxygen saturation (SmO2), blood lactate and end tidal CO2 (EtCO2) have recently gained attention as prognostic tools for early assessment of the status of patients with progressive hemorrhage, but lack the ability to adequately differentiate individual tolerance to hypovolemia...

BACKGROUND: Implantable cardioverter-defibrillator (ICD) therapy is well known to reduce mortality in selected patients with heart failure (HF). OBJECTIVE: To investigate whether monitored episodes of non-sustained ventricular tachycardia (NSVT) might predict future HF hospitalizations in ICD recipients with HF. METHODS: We examined 104 ICD recipients (mean age: 60 ± 10.1 years, 80.8 % male) with HF who were referred to our outpatient clinic for device follow-up...

Mechanical cardiovascular support devices are now widely used both in the setting of cardiogenic shock as well as during high risk cardiac catheterization procedures. We report a case of a young female patient who presented with presumed myocarditis and rapidly deteriorating decompensated heart failure requiring the implantation of an Impella Circulatory Support System. Upon transfer to our facility it was discovered that during transport, the Impella device had migrated through the left ventricle. She was emergently taken to the operating room where the Impella was surgically removed and biventricular support devices were placed...

BACKGROUND: During traumatic hemorrhage, the ability to identify shock and intervene before decompensation is paramount to survival. Lactate is extremely sensitive to shock, and its clearance has been demonstrated a useful gauge of shock and resuscitation status. Though lactate can be measured in the field, logistical constraints render it impractical in certain environments. The compensatory reserve represents a new clinical measurement reflecting the remaining capacity to compensate for hypoperfusion...

BACKGROUND: In patients with ventricular tachycardia or ventricular fibrillation (VT/VF) electrical storm (ES) undergoing catheter ablation (CA), hypotension due to refractory VT/VF, use of anesthesia, and cardiac stunning due to repeated implantable cardioverter-defibrillator shocks might precipitate acute hemodynamic decompensation (AHD). OBJECTIVE: We evaluated the outcomes of emergent cardiopulmonary support with extracorporeal membrane oxygenation (ECMO) to rescue AHD in patients undergoing CA of ES...

INTRODUCTION: Patients with cirrhosis have a high risk of sepsis, which confers a poor prognosis. The systemic inflammatory response syndrome (SIRS) criteria have several limitations in cirrhosis. Recently, new criteria for sepsis (Sepsis-3) have been suggested in the general population (increase of Sequential Organ Failure Assessment (SOFA) ≥2 points from baseline). Outside the intensive care unit (ICU), the quick SOFA (qSOFA (at least two among alteration in mental status, systolic blood pressure ≤100 mm Hg or respiratory rate ≥22/min)) was suggested to screen for sepsis...

General Practitioners frequently see children with medical conditions that may evolve into an emergency if not promptly attended to. The most common emergencies encountered in pediatric office practice are respiratory distress, dehydration, anaphylaxis, seizures and trauma. Assessment of children is sometimes difficult as the signs and symptoms might be subtle and not markedly expressed. Also, normal value of vital signs vary with age, thus their interpretation requires discrete knowledge of age appropriate values...
