Choriocarcinoma syndrome (CS) is a rare clinical entity within the spectrum of nonseminomatous germ-cell tumors (NSGCT). It is characterized by the abrupt establishment of rapidly progressive and hemorrhagic tumors associated with very high levels of the beta fraction of human chorionic gonadotropin ( β -hCG) and with a very poor prognosis, particularly in patients with β -hCG values above 50,000 IU/L. We present the case of a 17-year-old man with a sudden onset nonmassive hemoptysis. Physical examination revealed a right testicular mass...

One of the leading causes of morbidity and mortality in patients with heart failure is right ventricular (RV) dysfunction, especially if it is due to pulmonary hypertension. For a better understanding and treatment of this disease, precise hemodynamic monitoring of left and right ventricular parameters is important. For this reason, it is essential to establish experimental pig models of cardiac hemodynamics and measurements for research purpose. This article shows the induction of ARDS by using oleic acid (OA) and consequent right ventricular dysfunction, as well as the instrumentation of the pigs and the data acquisition process that is needed to assess hemodynamic parameters...

Heart failure (HF) and HF 30-day readmission rates have been a major focus of efforts to reduce health care cost in the recent era. Since the implementation of the Affordable Care Act (ACA) in 2012 and the Hospital Readmission Reduction Program (HRRP), concerted efforts have focused on reduction of 30-day HF readmissions and other admission diagnoses targeted by the HRRP. Hospitals and organizations have instituted wide-ranging programs to reduce short-term readmissions, but the data supporting these programs is often mixed...

Liver failure can occur in patients with or without underlying chronic liver disease (mainly cirrhosis) and is, respectively, termed acute on chronic liver failure or acute liver failure (ALF). In both cases, it is associated with marked systemic inflammation and profound hemodynamic disturbances, that is, increased cardiac output, peripheral vasodilation, and decreased systemic vascular resistance, on top of several superimposed etiologies of shock. In patients with cirrhosis, sepsis is the main cause of intensive care unit admission but portal hypertension-related gastrointestinal hemorrhage is also common...

BACKGROUND: Hypotension during surgery is linked to postoperative complications. Recently, a new hemodynamic algorithm intended to predict hypotensive events (hypotension probability indicator, HPI) has been developed. The aim of the present study is to test the discrimination and calibration properties of the HPI. METHODS: The intraoperative files of 23 patients undergoing cardiac and major vascular surgery receiving the HPI-based hemodynamic monitoring were retrospectively investigated for prediction of hypotensive events (mean arterial pressure < 65 mmHg)...

As a newly developed technique for hemodynamic monitoring, pulse contour cardiac output (PiCCO) monitoring takes great advantages in guiding shock resuscitation and fluid administration. PiCCO has been used more and more in burn patients in recent years, however there is no clinic consensus on how to apply PiCCO monitoring, understand the significance of PiCCO monitored parameters, and guide the treatment using PiCCO monitored parameters in patients with severe burns. Based on the current literature and the experts' clinical experience, national experts consensus on application of pulse contour cardiac output monitoring technique in severe burn treatment (2018 version ) is now issued by the Burn and Trauma Branch of Chinese Geriatrics Society, aiming to provide practical guidance for its usage in clinic...

BACKGROUND: Treatment of multiple organ failure frequently requires enhanced hemodynamic monitoring. When renal replacement is indicated, it remains unclear whether transpulmonary thermodilution (TPTD) measurements are influenced by renal replacement therapy (RRT) and whether RRT should be paused for TPTD measurements. Our aim was therefore to investigate the effect of pausing RRT on TPTD results in two dialysis catheter locations. MATERIALS AND METHODS: In total, 62 TPTD measurements in 24 patients (APACHE: 32 ± 7 [mean ± standard deviation (SD)]) were performed using the PiCCO™ system (Pulsion, Germany)...

Rotary blood pumps may be used as ventricular assist devices (VADs) to support patients with end-stage heart failure-'rotary VADs'. Clinically, rotary VADs are operated at a constant speed which is set manually. Due to inadequate haemodynamic monitoring equipment outside of the hospital setting, device speed remains the same for weeks or months at a time, leaving clinicians in the dark, and patients vulnerable to harmful over- or under-pumping events. Therefore, it would be beneficial to have an implantable sensor which can measure blood pressure at the rotary VAD inlet or outlet and detect the onset of adverse events...

Severe tricuspid regurgitation (TR) is reported to represent a hemodynamic pattern similar to that of constrictive pericarditis (CP), which should be clearly differentiated for appropriate management. We report the case of a patient with severe TR due to atrial fibrillation (AF) in whom hemodynamic monitoring played a role in the selection of the management strategy. An 81-year-old Japanese man with chronic AF was admitted due to worsening heart failure. Echocardiography showed the dilation of bilateral atria and a right ventricle with severe TR...

Ben Gelbart
Sepsis is a leading cause of morbidity and mortality in children with a worldwide prevalence in pediatric intensive care units of approximately 8%. Fluid bolus therapy (FBT) is a first line therapy for resuscitation of septic shock and has been a recommendation of international guidelines for nearly two decades. The evidence base supporting these guidelines are based on limited data including animal studies and case control studies. In recent times, evidence suggesting harm from fluid in terms of morbidity and mortality have generated interest in evaluating FBT...

Postural Orthostatic Tachycardia Syndrome (POTS) is a variant of cardiovascular autonomic disorder characterised by an excessive heart rate increase on standing and orthostatic intolerance. POTS affects younger individuals 15-45 years old with a distinct female predominance (≈80%). The prevalence ranges between 0.2 and 1.0% in developed countries. The onset of POTS is typically precipitated by immunological stressors such as viral infection, vaccination, trauma, pregnancy, surgery or psychosocial stress. The most common complaints are dizziness, weakness, rapid heartbeat and palpitation on standing...

Skillfully implemented mechanical ventilation (MV) may prove of immense benefit in restoring physiologic homeostasis. However, since hemodynamic instability is a primary factor influencing mortality in acute respiratory distress syndrome (ARDS), clinicians should be vigilant regarding the potentially deleterious effects of MV on right ventricular (RV) function and pulmonary vascular mechanics (PVM). During both spontaneous and positive pressure MV (PPMV), tidal changes in pleural pressure (PPL ), transpulmonary pressure (PTP , the difference between alveolar pressure and PPL ), and lung volume influence key components of hemodynamics: preload, afterload, heart rate, and myocardial contractility...

Evaluation of intrathoracic pressure is the cornerstone of the understanding of heart-lung interactions, but is not easily feasible at the bedside. Esophageal pressure (Pes ) has been shown to be a good surrogate for intrathoracic pressure and can be more easily measured using a small esophageal catheter, but is not routinely employed. It can provide crucial information for the study of heart-lung interactions in both controlled and spontaneous ventilation. This review presents the physiological basis, the technical aspects and the value in clinical practice of the measurement of Pes ...

Background Effort intolerance, measured objectively by reduced peak oxygen consumption (Vo2 ), has been considered as an important prognosticator in degenerative mitral regurgitation (MR). However, its mechanism is unknown. Methods and Results In 25 asymptomatic/minimally symptomatic patients with grade III+ or greater degenerative MR undergoing semisupine invasive exercise testing, Doppler estimates and invasive measurement of systolic (SPAP) and mean pulmonary artery pressure (MPAP) and cardiac output (CO) were simultaneously obtained...

PURPOSE OF REVIEW: A major goal in neurocritical care is to monitor for and prevent secondary brain injuries. However, injuries occurring at the cellular and molecular levels evade detection by conventional hemodynamic monitoring and the neurological exam. Cerebral microdialysis (CMD) is an invasive means of providing nearly continuous measurements of cerebral metabolism and is a promising tool that can detect signs of cellular distress before systemic manifestations of intracranial catastrophe...
