INTRODUCTION Optimal ventilator management for patients with acute respiratory distress syndrome (ARDS) remains uncertain. Lower tidal volume ventilation appears to be beneficial, but optimal management of positive end-expiratory pressure (PEEP) remains unclear. The Esophageal Pressure-Guided Ventilation 2 Trial (EPVent2) aims to examine the impact of(More)
PURPOSE We investigated the reproducibility of passive leg raise (PLR) and fluid bolus (BOLUS) using the Non-Invasive Cardiac Output Monitor (NICOM; Cheetah Medical, Tel Aviv, Israel) for assessment of fluid responsiveness (FR) in spontaneously breathing emergency department (ED) patients. METHODS Prospective, observational study of a convenience sample(More)
PURPOSE To evaluate the use of ocular photodynamic therapy (OPT) with verteporfin in patients with choroidal neovascularization (CNV) from ocular histoplasmosis syndrome (OHS) and to compare these results with those for a natural history group. METHODS A retrospective chart review was performed to identify cases of CNV secondary to OHS treated with OPT.(More)
BACKGROUND Surgical site infections (SSIs) are important sources of morbidity, prolonged hospital stays, and readmissions, so they have become a major economic burden. We hypothesized that surgical wound assessment by sonography (SWATS) used at the bedside would detect wound fluid collections and that the presence of such collections would predict SSI(More)
The antagonistic effects of helium pressure and certain inhalation anesthetics on the dopamine-sensitive cAMP response in the caudate nucleus of rat brain were examined. Helium pressure suppressed basal, dopamine-stimulated, and anesthetic-stimulated cAMP levels. These data indicate that by reversing the effects of pressure on dopaminergic transmission in(More)
