OBJECTIVE To investigate whether stroke volume variations obtained with the pressure recording analytic method can predict fluid responsiveness in mechanically ventilated patients with circulatory failure. DESIGN Prospective study. SETTING Surgical intensive care unit of a university hospital. PATIENTS Thirty-five mechanically ventilated patients with(More)
Orthotopic liver transplantation (OLT) remains a potentially hemorrhagic procedure. Rotational thromboelastometry (ROTEM) is a point-of-care device used to monitor coagulation during OLT. Whether it allows blood loss and transfusions to be reduced during OLT remains controversial. Excellent correlations and predictive values have been found between ROTEM(More)
OBJECTIVES The aim was to compare the antimicrobial efficacy of the silver impregnated collagen coated polyester vascular graft (IGS) with an identical graft combining silver and triclosan (IGSy). METHODS This was an in vitro study. A non-antimicrobial collagen polyester vascular graft served as control (IG). The IG, IGS, and IGSy grafts were contaminated(More)
BACKGROUND Respiratory-induced pulse pressure variations obtained with an arterial line (ΔPP(ART)) indicate fluid responsiveness in mechanically ventilated patients. The Infinity® CNAP™ SmartPod® (Dräger Medical AG & Co. KG, Lübeck, Germany) provides noninvasive continuous beat-to-beat arterial blood pressure measurements and a near real-time pressure(More)
Catheter-related bladder discomfort (CRBD) is an unrecognized clinical event. Symptoms of CRBD secondary to an indwelling urinary catheter mimic those of an overactive bladder, i.e. urinary frequency and urgency with or without urge incontinence. Stimulation of muscarinic receptors located in the bladder wall by the catheter is the triggering factor.(More)
BACKGROUND The accuracy of currently available devices using pulse contour analysis without external calibration for cardiac index (CI) estimation is negatively impacted by hyperdynamic states, low systemic vascular resistance (SVR), and abrupt changes in SVR. The aim of this study was to evaluate the accuracy of a new device, the Pulsioflex (Pulsion(More)
Non-invasive respiratory variations in arterial pulse pressure using infrared-plethysmography (PPVCNAP) are able to predict fluid responsiveness in mechanically ventilated patients. However, they cannot be continuously monitored. The present study evaluated a new algorithm allowing continuous measurements of PPVCNAP (PPVCNAPauto) (CNSystem, Graz, Austria).(More)
OBJECTIVE The primary objective of this retrospective study was to analyze the early impact of chimney (CG) versus fenestrated grafts (FG) on renal parenchymal vascularization and function. METHODS All consecutive patients with juxta-renal abdominal aortic aneurysm (JR-AAA) treated by endovascular repair from December 2013 to July 2014 at the vascular(More)
We report the case of an acute respiratory failure in a 36-year-old woman who presented a peripartum cardiomyopathy (PPCM). PPCM is a dilated cardiomyopathy with impaired systolic function that occurs between the last month of pregnancy and the five months following delivery. It is a rare disorder of unknown origin associated with high mortality (50%).(More)
