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 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)
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)
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)
BACKGROUND Adult deformity correction spine surgery can be associated with significant perioperative pain because of inflammatory, muscular, neuropathic, and postsurgical pain. α-2 Agonists have intrinsic antinociceptive and antihyperalgesic properties that can potentially reduce both postoperative opioid consumption and pain. We hypothesized that(More)
BACKGROUND Perioperative pulmonary hypertension remains a clinical challenge. The phosphodiesterase enzyme type III inhibitor milrinone produces pulmonary vasodilation but lacks selectivity. Sildenafil, a phosphodiesterase enzyme type V inhibitor, can also induce relaxation of the pulmonary vasculature; however, only the oral formulation is presently(More)
