BACKGROUND Continuous passive motion after major knee surgery optimizes the functional prognosis but causes severe pain. The authors tested the hypothesis that postoperative analgesic techniques influence surgical outcome and the duration of convalescence. METHODS Before standardized general anesthesia, 56 adult scheduled for major knee surgery were(More)
OBJECTIVES To describe the current practice of physicians, to report complications associated with endotracheal intubation (ETI) performed in THE intensive care unit (ICU), and to isolate predictive factors of immediate life-threatening complications. DESIGN Multiple-center observational study. SETTING Seven intensive care units of two university(More)
Prolonged controlled mechanical ventilation (MV) is known to induce diaphragmatic oxidative stress that seems to be an important factor reducing force-generating capacity. To better understand the cellular mechanisms involved, this work examined the effect of short vs. prolonged MV on antioxidant defense in the diaphragm. Prospective, randomized, controlled(More)
STUDY OBJECTIVE In most weaning studies, failure group patients are reventilated prior to extubation, thus compromising the evaluation of the applied weaning indices' predictive values. This study determines the usefulness of both standard and recent indices in predicting successful extubation following prolonged mechanical ventilation. DESIGN AND METHODS(More)
BACKGROUND Continuous peripheral nerve block (CPNB) is the technique of choice for postoperative analgesia after painful orthopedic surgery. However, the incidence of neurologic and infectious adverse events in the postoperative period are not well established. This issue was the aim of the study. METHODS Patients scheduled to undergo orthopedic surgery(More)
BACKGROUND Neurally adjusted ventilatory assist (NAVA) is a new mode of mechanical ventilation that delivers ventilatory assist in proportion to the electrical activity of the diaphragm. This study aimed to compare the ventilatory and gas exchange effects between NAVA and pressure support ventilation (PSV) during the weaning phase of critically ill patients(More)
PURPOSE The aim of this study was to assess the incidence and causes of cardiac arrests related to anesthesia. METHODS All patients undergoing anesthesia over a six year period were included in a prospective study. The cardiac arrests encountered during anesthesia and the first twelve postoperative hours in the PACU or ICU were analysed. For each arrest,(More)
OBJECTIVE This study examined, using noninvasive means, the changes in breathing pattern and inspiratory muscle pressure-time indices during difficult progressive withdrawal of pressure-support ventilation. DESIGN A prospective analysis of the temporal evolution of several respiratory variables in difficult-to-wean patients. SETTING A university(More)
To evaluate efficacy and adverse events related to inhaled sevoflurane for long-term sedation compared with standard intravenous (IV) sedation with propofol or midazolam. Randomized controlled trial. Sixty intensive care unit (ICU) patients expected to require more than 24 h sedation were randomly assigned to one of three groups: group S, inhaled(More)
OBJECTIVES To assess whether the use of iodinated contrast medium increases the incidence of acute kidney injury in ICU patients, compared with patients not receiving iodinated contrast medium. DESIGN Prospective observational matched cohort study. SETTING Two ICUs in two tertiary teaching hospitals. PATIENTS A total of 380 adults were included (20%(More)
