Filter by:Pacients who use mechanical ventilation (MV) need to pass weaning, a interruption process of ventilatory support. To predict this outcome, several scores have been developed, however, fail index in weaning and extubation remains high. The objective of this study is to evaluate the effect of ExPreS - Extubation Predictive Score - on rates of successful extubation. By a randomized clinical trial, this reseach will take place in ICUs of several hospitals. Therefore, it is expected that a difference between devices to predict extubation sucess exists and, because ExPreS is a protocol that evaluates different parameters related to many organs and systems, it presents a better capacity of predicting extubation sucess in MV patients.
The purpose of this study is to characterize the functionality of transcatheter implantation of the Medtronic Harmony Transcatheter Pulmonary Valve (TPV) achieved by real-world implanters.
Most patients in ICU are treated with a combination of analgesics and sedatives in most cases. Due to the different mechanism of different sedative and analgesic drugs, different antagonistic or synergistic effects may occur when combined with drugs, resulting in different clinical effects, especially significant effects on ventilators for patients with assisted breathing. Therefore, this study hopes to compare the effects of different sedative and analgesic drug combinations on the duration of mechanical ventilation for patients with ventilators, so as to guide the clinical adoption of a more reasonable sedative and analgesic scheme.
Coronavirus-2019 disease (COVID-19) is a highly infectious respiratory disease that causes respiratory, physical and psychological dysfunction in patients. With the increased understanding of the severity of COVID-19 and clinical evidence in accordance with the opinions of first-line clinical experts involved in the treatment of this epidemic, the investigators believe that the participation of patients with sequelae of COVID-19 in a Pulmonary Rehabilitation Program would be of utmost importance. According to recent scientific recommendations for patients with sequelae of COVID-19, respiratory rehabilitation would alleviate symptoms of dyspnea, anxiety and depression and, eventually, improve physical functions and quality of life. Therefore, it is essential to anticipate early rehabilitation after the acute phase of ARDS, in order to limit the severity of the effects of the ICU and promote rapid functional recovery. Physiotherapy will play a role in providing exercise, mobilization and rehabilitation interventions for survivors of critical illnesses associated with COVID-19, in order to enable a functional social return.
In patients with acute hypoxemic respiratory failure (AHRF), High Flow Nasal Therapy (HFNT) improves oxygenation, tolerance, and decrease work of breathing as compared to standard oxygen therapy by facemask. Current guidelines recommend adjusting oxygen flow rates to keep the oxygen saturation measured by pulse oximetry (SpO2) in the target range and avoid hypoxemia and hyperoxemia. The hypothesis of the study is that closed loop oxygen control increases the time spent within clinically targeted SpO2 ranges and decreases the time spent outside clinical target SpO2 ranges as compared to manual oxygen control in ICU patients treated with HFNT.
The study project will aim at the evaluation of the occurrence of exercise desaturation phenomenon during two different modalities of exercise (walking and stepping condition). This study will allow determining the sensibility of the 3-minute step test to detect exercise desaturation, in comparison with the gold standard (6-minute walking test). The 3-minute step test could therefore appear as a complementary tool for the evaluation of oxygen desaturation in chronic respiratory disease.
This study will monitor device performance and outcomes of the SAPIEN 3 Transcatheter Heart Valve (THV) System in subjects with a dysfunctional right ventricular outflow tract (RVOT) conduit or previously implanted surgical valve in the pulmonic position with a clinical indication for intervention.
The present study is aimed to establish the epidemiological characteristics and clinical outcomes of mechanically ventilated children with acute hypoxemic respiratory failure (AHRF), defined as PaO2/FiO2 ≤300 mmHg on PEEP≥5 cmH2O and FiO2≥0.3, admitted in a network of pediatric hospitals in Spain.
The objective of this study is to investigate i) the effect of 3 weeks IMT to adults post-stroke to maximal inspiratory pressure (MIP) and ii) the effects of 3 weeks IMT to the degree of dependency in activities of daily living, endurance in gait, fatigue, voice volume, phonation endurance, and expiratory function. Methods/Design: Randomised controlled trial (RCT) comparing IMT to conventional neurorehabilitation (usual practise). 80 patients, with reduced maximal inspiration pressure (MIP) hospitalized at a specialized neurorehabilitation hospital in Denmark will be included.
Episodic breathlessness is a common and distressing symptom in patients with advanced disease such as cancer, chronic obstructive pulmonary disease (COPD) and chronic heart failure. Since the short duration of the majority of breathless episodes limits the effectiveness of pharmacological interventions (e.g. opioids), non-pharmacological management strategies play a major role. As non-pharmacological strategies patients use, for example, cognitive and behavioural methods such as breathing or relaxation techniques. The aim of the study is to test a brief cognitive and behavioural intervention for an improved management of episodic breathlessness. Initially, a Delphi procedure with international experts has been used to develop the brief intervention consisting of various non-pharmacological strategies to enhance the management of breathless episodes. In the single-arm therapeutic exploratory trial (phase II), the feasibility and potential effects of the brief intervention, such as patient-reported breathlessness mastery, episodic breathlessness characteristics, quality of life, symptom burden, caregivers' burden, and breathlessness in general will be examined. The results of the study form the basis for planning and implementing a subsequent confirmatory randomized control trial (phase III).
