PURPOSE To determine the value of Vd/Vt as a predictor of extubation failure in patients with mechanical ventilation admitted to the intensive care units. DESIGN A prospective, observational cohort study conducted from 1 September 2010 to 1 March 2011. SETTING General intensive care unit (G-ICU) of a third level university hospital. PATIENTS OR PARTICIPANTS The study included patients on ...

Background/Objective. Hydrocortisone, administered to ventilated preterm neonates to facilitate extubation, has no adverse long-term effects, but short-term pulmonary effects have not been described previously. In the present study, we analyzed effects of hydrocortisone on ventilator settings and FiO(2) in ventilator-dependent preterm infants. Patients and Methods. Fifty-five preterm children w...

BACKGROUND Electrical impedance tomography (EIT) is a real-time bedside monitoring tool, which can reflect dynamic regional lung ventilation. The aim of the present study was to monitor regional gas distribution in patients with acute respiratory distress syndrome (ARDS) during positive-end-expiratory pressure (PEEP) titration using EIT. METHODS Eighteen ARDS patients under mechanical ventila...

Cophylogenetic studies aim at testing specific hypotheses to understand the nature of coevolving associations between sets of organisms, such as host and parasites. Monogeneans and their hosts provide and interesting platform for these studies due to their high host specificity. In this context, the objective of the present study was to establish whether the relationship between Anacanthorus sp...

Extracorporeal membrane oxygenation (ECMO) is used for refractory respiratory failure. Normally, ECMO is implanted in intubated patients as a last resort. We report the case of a non-intubated patient who benefited from veno-venous (VV) ECMO. A 35-year old cystic fibrosis man presented a severe respiratory decompensation with refractory hypercapnia. We opted for an ECMO instead of mechanical ve...

STUDY OBJECTIVES To determine which respiratory function tests best predicted diaphragmatic strength in patients with amyotrophic lateral sclerosis. PATIENTS AND METHODS Patients referred for pulmonary evaluation were included (n = 25) if they underwent measurement of transdiaphragmatic pressure (Pdi) and one or more of the following on the same day: upright FVC, supine FVC, upright FEV(1), s...

Patients with chronic obstructive pulmonary disease (COPD) exhibit improved exercise capacity after physical training due to reconditioning and improved ventilatory efficiency. Other possible effects are improved ventilatory muscle function and desensitization to dyspnea. We compared general physical training (GPT), consisting of walking and stair climbing exercises, with inspiratory muscle tra...

BACKGROUND Chronic obstructive pulmonary disease (COPD) exacerbation increases mortality and resources used associated with hospitalization. We studied whether early home monitoring reduces the rate of readmission and if there are any predictor variables. PATIENTS AND METHODS We performed a prospective, controlled, parallel-group study in patients who were hospitalized for COPD. Patients whos...
