AIM To investigate the effect of fasting times for clear fluids and solids/non-clear fluids on gastric content volume using magnetic resonance imaging (MRI). METHODS Pediatric patients undergoing diagnostic MRI under deep propofol sedation, with the stomach located within the area of diagnostic study, were included in this clinical observational study. According to standard institutional guid...
INTRODUCTION Preventing perioperative tissue oxygen debt contributes to a better postoperative recovery. Whether the beneficial effects of fluids and inotropes during optimization of the oxygen delivery index (DO2I) in high-risk patients submitted to major surgeries are due to fluids, to inotropes, or to the combination of the two is not known. We aimed to investigate the effect of DO2I optimiz...
This study was designed to examine the effects of ambient heat on firefighters' physical task performance, and physiological and perceptual responses when sleep restricted during simulated wildfire conditions. Thirty firefighters were randomly allocated to the sleep restricted (n = 17, SR; 19 °C, 4-h sleep opportunity) or hot and sleep restricted (n = 13, HOT + SR; 33 °C, 4-h sleep opportunity)...
Branched networks are ubiquitous throughout nature, particularly found in tissues that require large surface area within a restricted volume. Many tissues with a branched architecture, such as the vasculature, kidney, mammary gland, lung and nervous system, function to exchange fluids, gases and information throughout the body of an organism. The generation of branched tissues requires regulati...
Recent studies suggest that current fluid strategies may result in excessive administration of both fluids and electrolytes. Perioperative fluid administration is dictated by an algorithmic approach, taking account of pre-operative deficit, maintenance requirements, and extrapolated third space losses. Salt and water overload is associated with pulmonary edema, ileus, and delayed wound healing....
This article aims at providing an overview on fluid therapy in cardiac anesthesia in order to support training of anesthetists. Intraoperative fluid therapy is an integral part of anesthesia management [1, 2]. In an attempt to prevent development of organ damage it is of major importance to ensure adequate fluid and volume supply [3]. Patients who have to undergo cardiac surgery present a major...

As a cylinder spins in an infinite media, viscous shear forces induce fluid motion and circular streamlines are generated. For Newtonian fluids, a simple analytical solution is possible and widely known. The hydrodynamics of nonNewtonian fluids, however, can be quite complex under such conditions. This paper investigates the behavior of a wide range of non-Newtonian fluids in the infinite cylin...
