Vasoconstriction with phenylephrine increases cardiac output in preload dependent patients
General Anaesthesia (GA) is accompanied by a marked decrease in sympathetic outflow and thus loss of vasomotor control of cardiac preload. The use of...

Dynamic changes of hepatic vein Doppler velocities predict preload responsiveness in mechanically ventilated critically ill patients
BackgroundAssessment of dynamic parameters to guide fluid administration is one of the mainstays of current resuscitation strategies. Each test has...
-
Refilling and preload dependence failed to predict cardiac index decrease during fluid removal with continuous renal replacement therapy
BackgroundFluid removal can reduce the burden of fluid overload after initial resuscitation. According to the Frank-Starling model, iatrogenic...

Simultaneous venous–arterial Doppler during preload augmentation: illustrating the Doppler Starling curve
Providing intravenous (IV) fluids to a patient with signs or symptoms of hypoperfusion is common. However, evaluating the IV fluid ‘dose–response’...

Prediction of preload dependency using phenylephrine-induced peripheral perfusion index during general anaesthesia: a prospective observational study
BackgroundTracking preload dependency non-invasively to maintain adequate tissue perfusion in the perioperative period can be challenging.The effect...

Blood volume in patients likely to be preload responsive: a post hoc analysis of a randomized controlled trial
BackgroundPreload responsive postoperative patients with signs of inadequate organ perfusion are commonly assumed to be hypovolemic and therefore...

The effect of gravity-induced preload change on the venous excess ultrasound (VExUS) score and internal jugular vein Doppler in healthy volunteers
BackgroundThe venous excess ultrasound (VExUS) score is a multi-organ Doppler approach to assess venous congestion. Despite growing use of VExUS in...

Differential Cardiac Responses after Passive Leg Raising
This study retrospectively examined the hemodynamic effects of passive leg raising (PLR) in mechanically ventilated patients during fluid removal...

Tidal volume challenge to predict preload responsiveness in patients with acute respiratory distress syndrome under prone position
BackgroundProne position is frequently used in patients with acute respiratory distress syndrome (ARDS), especially during the Coronavirus disease...
-
Left atrial contraction strain and controlled preload alterations, a study in healthy individuals
BackgroundIn order to assess left atrial contractile function in disturbed circulatory conditions, it is necessary to have a clear understanding of...

Should we use diastolic function parameters to determine preload responsiveness in cardiac surgery? A pilot study
BackgroundLeft ventricular (LV) diastolic function (DF) may play an important role in predicting fluid responsiveness. However, few studies assessed...
-
A method for calculating left ventricular end-diastolic volume as an index of left ventricular preload from the pre-ejection period, ejection time, blood pressure, and stroke volume: a prospective, observational study
BackgroundLeft ventricular end-diastolic volume (EDV) is a major determinant of cardiac preload. However, its use in fluid management is limited by...

Cardiac arrest and cardiopulmonary resuscitation in pediatric patients with cardiac disease: a narrative review
Children with cardiac disease are at a higher risk of cardiac arrest as compared to healthy children. Delivering adequate cardiopulmonary...

Bioreactance reliably detects preload responsiveness by the end-expiratory occlusion test when averaging and refresh times are shortened
BackgroundThe end-expiratory occlusion (EEXPO) test detects preload responsiveness, but it is 15 s long and induces small changes in cardiac index...

Predicting cardiac arrest after neonatal cardiac surgery
ObjectiveIn-hospital cardiac arrest (IHCA) following cardiac surgery is a rare but consequential event with detrimental effects on patient outcomes,...

Post Cardiac Arrest Care in the Cardiac Intensive Care Unit
Purpose of ReviewCardiac arrests constitute a leading cause of mortality in the adult population and cardiologists are often tasked with the...

The increase in cardiac output induced by a decrease in positive end-expiratory pressure reliably detects volume responsiveness: the PEEP-test study
BackgroundIn patients on mechanical ventilation, positive end-expiratory pressure (PEEP) can decrease cardiac output through a decrease in cardiac...
