BACKGROUND Dysphagia and aspiration occur frequently in stroke patients. The aim of the present study was to evaluate 2 consistencies (liquid and spoon-thick/pudding-like) regarding the risk of aspiration and to determine the usefulness of a bedside speech therapy assessment to predict risk of aspiration. METHODS This randomized, crossover clinical trial(More)
BACKGROUND AND OBJECTIVES Learning curves have proved to be useful tools to monitor the performance of a worker on a new assignment. Those curves have been used to evaluate several medical procedures. The objective of this study was to evaluate the learning of orotracheal intubation (OTI) with the Truview EVO2 laryngoscope with the CUSUM learning curve. (More)
PURPOSE To develop an animal model of diaphragmatic electrical stimulation able to generate an appropriate ventilatory support through the direct implantation of electrodes in the diaphragm (electroventilation). METHODS Six New Zealand female rabbits (2-3 kg) were placed on mechanical ventilation. Then, a laparotomy was performed in order to identify the(More)
OBJECTIVE To evaluate the changes in ventilatory mechanics and hemodynamics that occur in patients dependent on mechanical ventilation who are subjected to a standard respiratory therapy protocol. METHODS This experimental and prospective study was performed in two intensive care units, in which patients dependent on mechanical ventilation for more than(More)
an important role. Most patients are under 40 years of age and were previously healthy. The male/female ratio is as high as 1:4 in some studies, (1) although other studies have shown little gender bias. The onset of the disease is acute or subacute, progressing over the course of two to three weeks. The most common form of presentation is lymphadenopathy,(More)
We describe a case series of 35 patients with either benign (14) or malignant (21) tracheal stenosis who were treated using a novel silicone stent, the HCPA-1, designed to prevent migration. Between March 2001 and September 2008, 13 women and 22 men received 41 HCPA-1 stents. The median duration of stenting in benign cases was 457 days (range, 4-2,961(More)
