Trauma patients with "compensated" internal hemorrhage may not be identified with standard medical monitors until signs of shock appear, at which point it may be difficult or too late to pursue life-saving interventions. We tested the hypothesis that a novel machine-learning model called the compensatory reserve index (CRI) could differentiate tolerance to acute volume loss of individuals well ...

PURPOSE To evaluate histopathological alterations triggered by brain death and associated trauma on different solid organs in rats. METHODS Male Wistar rats (n=37) were anesthetized with isoflurane, intubated and mechanically ventilated. A trepanation was performed and a balloon catheter inserted into intracraninal cavity and rapidly inflated with saline to induce brain death. After induction...

BACKGROUND There have been many concerns about alteration in hemodynamic parameters within and shortly after endotracheal intubation (ETI) in patients scheduled for elective coronary artery bypass grafting (CABG). OBJECTIVES We compared the attenuation effect of magnesium sulfate and lidocaine on hemodynamic responses after ETI, in patients undergoing CABG. PATIENTS AND METHODS In this rand...

INTRODUCTION Pneumopericardium, defined as the presence of gas in the pericardial sac, is a rare condition caused mostly by trauma. Tension pneumopericardium is a cause of hemodynamic instability; hence, it consists in a life-threatening situation and should be regarded in blunt chest trauma. CASE REPORT A 51-year-old male was victim of a 4m fall and burial. He was stable upon admission and p...

OBJECTIVE To assess the hemodynamic profile of cardiac surgery patients with circulatory instability in the early postoperative period (POP). METHODS Over a two-year period, 306 patients underwent cardiac surgery. Thirty had hemodynamic instability in the early POP and were monitored with the Swan-Ganz catheter. The following parameters were evaluated: cardiac index (CI), systemic and pulmona...

Systolic anterior motion (SAM) of mitral valve is the prolapse of a mitral leaflet into the left ventricle outflow tract (LVOT) during systole, causing LVOT obstruction and mitral valve regurgitation. We report the case of a patient who developed SAM-induced hemodynamic instability during bleeding with a clinical picture resembling pulmonary edema. A 77-year-old woman was admitted to our emerge...

INTRODUCTION Necrotizing fasciitis (NF), a necrotizing infection of the soft tissue, is a medical emergency usually occurring in the lower extremities and abdominal regions and often difficult to diagnose promptly. PRESENTATION OF CASE This case report looks at one atypical presentation of NF with the unusual location of the vulva and no known associated comorbidities or risk factors. DISCU...

c Right ventricular dysfunction (RVD) is the most common cause of short-term mortality in patients with acute pulmonary embolism (PE).1 Shock and hemodynamic instability, defined as systolic blood pressure below 90mmHg or a fall of more than 40mmHg, is a clinical marker of high risk and identifies patients who may benefit from early thrombolysis.2 However, in PE patients without hemodynamic com...

Introduction. General anesthesia is frequently employed in neck surgery procedures. However, patients at high risk for general anesthesia, regional options, such as the superficial cervical plexus block, warrant careful consideration. Patients with mediastinal lymph node enlargement face an elevated of airway obstruction and hemodynamic instability during induction. In selected surgeries, inclu...

An adolescent female was admitted to the pediatric intensive care unit in septic shock. She developed multisystem organ dysfunction including pancreatitis with myocardial dysfunction and hemodynamic instability unresponsive to medical management necessitating veno-arterial extracorporeal support. Streptococcus Constellata and Fusobacterium necrophorum were isolated from blood cultures. This is ...
