In patients at risk for sudden ethanol (ETOH) intravascular absorption, prompt treatment of pulmonary hypertension (PHTN) will minimise the risk of cardiovascular decompensation. We investigated the haemodynamic effects of intravenous ETOH and the pulmonary vasodilatory effects of a sildenafil analogue (UK343-664) and nitroglycerin (NTG) during ETOH-induced(More)
BACKGROUND The use of lung-protective ventilation (LPV) strategies may minimize iatrogenic lung injury in surgical patients. However, the identification of an ideal LPV strategy, particularly during one-lung ventilation (OLV), remains elusive. This study examines the role of ventilator management during OLV and its impact on clinical outcomes. METHODS(More)
PURPOSE Thoracic surgery requiring 1-lung ventilation (OLV) is associated with significant postoperative pulmonary complications (PPCs) due to patient- and surgery-specific risk factors. The aim of this study is to determine whether the oxygenation index (OI) (fraction of inspired oxygen × mean airway pressure/partial pressure of oxygen) during OLV predicts(More)
Perioperative hemodynamic optimization of the high-risk surgical patient is associated with reduced postoperative morbidity and mortality. The hemodynamic parameters to be optimized (using goal-directed algorithms) encompass preload, contractility, afterload, volume responsiveness, and end-organ perfusion. Current hemodynamic monitors facilitate multi-modal(More)
Plasmapheresis is a well-known therapeutic procedure for several medical conditions in which removal of circulating antibodies or albumin-bound toxins is desired. Circulating plasma cholinesterase enzyme levels are also depleted with plasmapheresis. This action causes patients to be susceptible to prolonged neuromuscular blockade when neuromuscular blocking(More)
OBJECT Earlier definitions of acute renal failure are not sensitive in identifying milder forms of acute kidney injury (AKI). The authors hypothesized that by applying the RIFLE criteria for acute renal failure (Risk of renal dysfunction, Injury to the kidney, Failure of kidney function, Loss of kidney function, and End-stage kidney disease) to thoracic and(More)
OBJECT Major spinal surgery in adult patients is often associated with significant intraoperative blood loss. Rotational thromboelastometry (ROTEM) is a functional viscoelastometric method for real-time hemostasis testing. In this study, the authors sought to characterize the coagulation abnormalities encountered in spine surgery and determine whether a(More)
