Protective Mechanical Ventilation during General Anesthesia for Open Abdominal Surgery Improves Postoperative Pulmonary Function
2013
Abstract Background: The impact of intraoperative ventilation on postoperative pulmonary complications is not defined. The authors aimed at determining the effectiveness of protective mechanical ventilation during open abdominal surgery on a modified Clinical Pulmonary Infection Score as primary outcome and postoperative pulmonary function. Methods: Prospective randomized, open-label, clinical trial performed in 56 patients scheduled to undergo elective open abdominal surgery lasting more than 2 h. Patients were assigned by envelopes to mechanical ventilation with tidal volume of 9 ml/kg ideal body weight and zero-positive end-expiratory pressure (standard ventilation strategy) or tidal vol…
Closed-Loop Automatic Oxygen Control (CLAC) in Preterm Infants: A Randomized Controlled Trial
2014
BACKGROUND AND OBJECTIVE: In preterm infants receiving supplemental oxygen, routine manual control (RMC) of the fraction of inspired oxygen (FIO2) is often difficult and time consuming. We developed a system for closed-loop automatic control (CLAC) of the FIO2 and demonstrated its short-term safety and efficacy in a single-center study. The objective of this study was to test the hypothesis that this system is more effective than RMC alone in maintaining arterial oxygen saturation within target levels when evaluated over 24 hours under routine conditions and with different target levels. METHODS: We performed a multicenter, randomized controlled, crossover clinical trial in 34 preterm infa…
Evolution Over Time of Ventilatory Management and Outcome of Patients With Neurologic Disease
2021
OBJECTIVES: To describe the changes in ventilator management over time in patients with neurologic disease at ICU admission and to estimate factors associated with 28-day hospital mortality. DESIGN: Secondary analysis of three prospective, observational, multicenter studies. SETTING: Cohort studies conducted in 2004, 2010, and 2016. PATIENTS: Adult patients who received mechanical ventilation for more than 12 hours. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Among the 20,929 patients enrolled, we included 4,152 (20%) mechanically ventilated patients due to different neurologic diseases. Hemorrhagic stroke and brain trauma were the most common pathologies associated with the need fo…

Adding a cooling vest during cycling improves performance in warm and humid conditions
2012
It is known that warm and humid environment reduces human physical performance. The present study examined whether the use of an ice-vest in such conditions can improve cycling performance. Seven participants cycled with consecutive, non-stop, 10-minute cycles of nine minutes at 60% of their (V) over dot O-2 max punctuated by a one-minute sprint at 80% (V) over dot O-2 max. The cycling protocol was continuously repeated until exhaustion. The protocol was performed with the ice-vest (ICE), worn after 30 min of cycling, and without the ice-vest throughout the protocol (CON). Ventilatory and thermal responses were continuously recorded. Electromyographic (EMG) signals from four muscles of the …
Ventilación mecánica no invasiva en el postoperatorio. Revisión clínica
2015
Non-invasive ventilation (NIV) is a method of ventilatory support that is increasing in importance day by day in the management of postoperative respiratory failure. Its role in the prevention and treatment of atelectasis is particularly important in the in the period after thoracic and abdominal surgeries. Similarly, in the transplanted patient, NIV can shorten the time of invasive mechanical ventilation, reducing the risk of infectious complications in these high-risk patients. It has been performed A systematic review of the literature has been performed, including examining the technical, clinical experiences and recommendations concerning the application of NIV in the postoperative per…
Automated Weaning from Mechanical Ventilation after Off-Pump Coronary Artery Bypass Grafting
2017
Background The discontinuation of mechanical ventilation after coronary surgery may prolong and significantly increase the load on intensive care unit personnel. We hypothesized that automated mode using INTELLiVENT-ASV can decrease duration of postoperative mechanical ventilation, reduce workload on medical staff, and provide safe ventilation after off-pump coronary artery bypass grafting (OPCAB). The primary endpoint of our study was to assess the duration of postoperative mechanical ventilation during different modes of weaning from respiratory support (RS) after OPCAB. The secondary endpoint was to assess safety of the automated weaning mode and the number of manual interventions to the…
Neuromuscular and Chest Wall Diseases in Pregnancy
2009
Patients with severe respiratory muscle impairment, in particular when vital capa-city is below 60% of the predicted normal values, are often discouraged frombecoming pregnant for fear of respiratory complications and the need for tra-cheostomy and invasive mechanical ventilation (1). A growing fetus can impairthe functioning of weak diaphragms resulting in lower vital capacity and respira-tory reserve and impair cough function. In addition, there is increased oxygenconsumption and ventilation requirement. Complications in pregnancy and theneed for analgesics and anesthesia during labor and delivery can also cause orexacerbate ventilatory failure.Neuromuscular DiseasesNeuromuscular diseases…
Ventilación mecánica no invasiva en pre e intraoperatorio y vía aérea difícil
2015
Non-invasive mechanical ventilation is a method of ventilatory assistance aimed at increasing alveolar ventilation, thus achieving, in selected subjects, the avoidance of endotracheal intubation and invasive mechanical ventilation, with the consequent improvement in survival. There has been a systematic review and study of the technical, clinical experiences, and recommendations concerning the application of non-invasive mechanical ventilation in the pre- and intraoperative period. The use of prophylactic non-invasive mechanical ventilation before surgery that involves significant alterations in the ventilatory function may decrease the incidence of postoperative respiratory complications. …
Post-Traumatic Stress Disorder: A Review of Therapeutic Role of Meditation Interventions
2019
This review is an attempt to provide a comprehensive view of post-traumatic-stress disorder (PTSD) and its therapy, focusing on the use of meditation interventions. PTSD is a multimodal psycho-physiological-behavioral disorder, which calls for the potential usefulness of spiritual therapy. Recent times witness a substantial scientific interest in an alternative mind-to-body psychobehavioral therapy; the exemplary of which is meditation. Meditation is a form of mental exercise that has an extensive, albeit still mostly empiric, therapeutic value. Meditation steadily gains an increasing popularity as a psychobehavioral adjunct to therapy in many areas of medicine and psychology. While the rev…
