Filter by:Neurally adjusted ventilatory assist (NAVA) is a new mode of mechanical ventilation that delivers ventilatory assist in proportion to neural effort. The investigators hope to compare the hemodynamic and pulmonary effect in children after surgical repair of congenital heart disease with right ventricular hypertrophic ventilated with Pressure control ventilation (PCV), Pressure support ventilation (PSV), and NAVA by a crossover study.
Prolonged mechanical ventilation patients rely on medical expenses per year had increased by nearly 20 billion in 15 years, so it is worthwhile to explore how to improve the respiratory function and even their quality of life of patients in Respiratory care wards (RCWs). This study used repeated experimental measurements and purpose sampling, and the investigators invited patients in respiratory care ward in northern Taiwan. They were randomly assigned to the experimental group and the control group. The experimental group was given 45 degree Semi-sitting 2 hrs and upper-limb exercise training 10 mins once a day. There were 29 prolonged mechanical ventilation (PMV) patients in the experimental group and 26 in the control group. Our conclusions showed that PMV patients can significantly improve the maximum inspiratory pressure (MIP) in the post-test while performed a 45-degree semi-sitting position with upper limb training for 4 weeks. The minute ventilation (MV) has a trend of increasing month by month in the experimental group, but it is necessary to consider whether it is due to the improvement of lung function or just cause of the increased oxygen consumption and accelerated respiratory rate, so it can not be inferred to improvement of the patient's condition or lung function.
This prospective, unblinded, pilot randomized cross-over trial of 2 modes of mechanical ventilation will compare measures of pulmonary mechanics, respiratory gas exchange, and patient comfort between conventional flow triggered mechanical ventilation and neurally adjusted ventilatory assist (NAVA) among 20 prematurely born infants and young children receiving invasive respiratory support for severe bronchopulmonary dysplasia (BPD).
This research is a single-blinded, randomized controlled trial involving mechanically ventilated children in Pediatric Intensive Care Unit, Cipto Mangunkusumo Hospital, Indonesia. Subjects were divided into two groups: intervention vs control group. Primary and secondary outcomes will be measure pre, during, and post treatment.
This study aims to capture preliminary safety and effectiveness information on a near-final humidifier device design and to provide data for more extensive research, if required. This feasibility study will investigate the following: process, resources, management, and scientific aspects of delivering humidification by the RespirAq humidifier device in ventilated patients.
Muscle atrophy and diaphragm dysfunction are common with prolonged mechanical ventilation (PMV). Electrical stimulation has been shown to be beneficial in severe chronic heart failure and chronic obstructive pulmonary disease. However, its effect on PMV is unclear. This study examined the effects of transcutaneous electrical diaphragmatic stimulation (TEDS) on respiratory muscle strength and weaning outcomes in patients with PMV.
Open heart surgeries are one of the major and complicated surgeries performed frequently in the world due to the prolongation of life expectancy and developments in medicine. As a result of these operations, not only the heart and vessels, but also all organs and systems depending on the systemic circulation are affected. Some biological inflammation markers have been determinant in determining cardiovascular risk. High neutrophil count was associated with increased mortality, while low lymphocyte count was a strong constant predictor of mortality. In addition, increased serum uric acid (UA) levels have been found to be associated with obesity, dyslipidemia, and hypertension, which is associated with cardiovascular disease risk. The aim of this study is to investigate the effects of patients who underwent coronary bypass surgery under elective conditions in Karadeniz Technical University Faculty of Medicine between 2008-2020 on in-hospital and 1-year mortality based on preoperative neutrophil / lymphocyte ratios and uric acid values.
Elderly patients have a higher incidence of morbidity and mortality due to the interaction of various factors such as decreased physiological reserves, concomitant comorbidities, multiple drug use, cognitive dysfunction, and frailty. Surgical stress, pain and associated lung complications are common problems in open heart surgeries that can affect morbidity and mortality. With a good postoperative pain control and improved respiratory mechanics, complications that may develop in patients can be significantly prevented, and the hospital cost can be reduced and the workforce loss of patients can be reduced by reducing the length of hospital stay in the intensive care unit. Thoracic epidural analgesia (TEA) is an anesthetic analgesia method that has positive effects on many organ systems as well as providing good pain control and is frequently used in open heart surgery. The aim of this study is to investigate the effects of TEA on postoperative respiratory mechanics in geriatric patients, based on analgesia levels, extubation times, length of stay in intensive care, arterial blood gases, morbidity and mortality.
Mechanical ventilation is a cornerstone in the management of severe forms of pneumonia, acute respiratory distress syndrome. It provides essential oxygen to patients, ventilates the lungs but also has deleterious effects like any treatment, in particular by reducing cardiac output by reducing venous return. Mechanical ventilation also has effects on the diaphragm: diaphragmatic dysfunction. It is explained by a prolonged inactivity of this muscle with a reduction of muscle fibers that can settle down quickly, after only a few days of mechanical ventilation. This dysfunction results in a reduction in the latter's ability to generate intrathoracic pressure necessary for ventilation, slows the withdrawal of mechanical ventilation and lengthens the duration of stay in intensive care unit. To reduce this dysfunction, phrenic stimulation has been proposed as an alternative to remuscler the diaphragm thanks to electrodes located on a central venous catheter, also used to deliver the usual therapies in intensive care unit. The HEMOSTIM study is interested in the effects of phrenic stimulation on regional ventilation, cardiac output and cerebral perfusion: investigator hypothesize that diaphragmatic stimulation allows an improvement of these parameters.
For the infant participating the study, ventilator settings and respiratory variables will be recorded every day and exported to a specific computer using the Servo Record Viewer version 1.0 (Maquet Critical Care AB, Getinge, Gothenburg, Sweden). Collected data gives the value for peak inspiratory pressure (PIP), expiratory tidal volume (Vt), peak Edi, minimum Edi, measured respiratory rate (RR), neural respiratory rate (nRR) and percentage of backup breaths for each minute. All the ventilator data will be inspected and compared with the event logs recorded automatically from the ventilator, which includes all the alarm notification, mode and setting changes, cables connection and disconnection data. Data during disconnection of the Edi cable, malfunction or dislocation of Edi catheter will be excluded from the analysis. The mean values during each day will be computed for each ventilatory variables. If there is a change in the ventilatory setting parameters, we will choose the one which was applied for longer duration in the 24-hour time period. The following clinical characteristics will be collected from medical records: gestational age at birth, birth weight, gender, the time and amount of feeding, medication during the study days, desaturation events, bradycardia events, suction time and methods.
