Filter by:This study will enroll 75 mechanically vented adults in the ICU to compare self-reported ease of communication, patient satisfaction, and patient anxiety and frustration levels between a group using a communication application on an iPad and a group using standard methods of communication while mechanically vented.
Postoperative Pulmonary Complications (PPC) are very common. It severely affects postoperative recovery, particularly in the abdominal surgery. Patients with laparoscopic resection of colorectal cancer generally have a higher age and decreased lung function reserve. At the same time, they prone to developing atelectasis due to the effects of pneumoperitoneum pressure. Therefore, they are a high-risk group of respiratory insufficiency and PPC. Mechanical ventilation with a low tidal volume is a routine in clinic nowadays. However, this conventional strategy will also result in atelectasis formation. Therefore, it may deteriorate the vulnerable lung function of patients undergoing laparoscopic resection of colorectal cancer. Patients with Acute Lung Injury or Acute Respiratory Distress Syndrome (ALI/ARDS) could benefit from the "open lung approach", including the use of positive end-expiratory pressure (PEEP) and recruitment maneuvers (RMs). Whether a lung protective mechanical ventilation strategy with medium levels of PEEP and repeated RMs, the "open lung approach", protects against respiratory insufficiency and PPC during laparoscopic resection of colorectal cancer is uncertain. The present study aims at comparing the effects of "open lung approach" mechanical ventilation strategy and conventional mechanical ventilation strategy in PPC, extra-pulmonary complications, length of hospital stay, biomarkers of lung injury and changes of respiratory function in patients undergoing general anesthesia for laparoscopic resection of colorectal cancer.
Although it is now recognized that a variety of respiratory abnormalities, such as diaphragmatic dysfunction, can be present in primary hypothyroidism and reverse with adequate hormone treatment, the role of thyroid hormone replacement therapy on respiratory system in patients with the nonthyroidal illness syndrome (NTIS) remains to be clarified. The NTIS has been found to be an independent risk factor for prolonged (> 13 days) mechanical ventilation. It is unclear, however, whether the NTIS is only a biochemical prognostic marker or it actually contributes to the development and progression of respiratory failure. The aim of this study will be to assess respiratory muscle function after thyroid hormone substitution therapy in mechanically ventilated patients with the NTIS.
The measurement of how much oxygen a baby consumes provides important information about the health of the baby, and of how much energy they are consuming. Currently, there is no device which measures either oxygen consumption, or another variable that depends on oxygen consumption - resting energy expenditure - in neonates or infants. Our group has developed a new device which can attach to any ventilator and measures these two variables with accuracy in the preclinical setting, including in rodents as small as severely preterm infants. The purpose of this study is to compare measurements of oxygen consumption and energy expenditure in neonates using this device and comparing it with a gold standard which is rarely used, a Douglas bag method in which expired gas is collected and later analyzed.
This study is an extension of the Spanish Initiative for Epidemiology, Stratification and Therapies of Acute respiratory failure (SIESTA) Network. The present study is aimed to establish the epidemiological characteristics and clinical outcomes of mechanically ventilated patients with acute hypoxemic respiratory failure [defined as a PaO2/FiO2 ≤300 mmHg on positive end-expiratory pressure (PEEP) of 5 cmH2O or more, and FiO2 of 0.3 or more] admitted in a network of Spanish hospitals.
Percutaneous dilatational tracheostomy (PDT), especially single-step dilatational tracheostomy (sd-PDT), is now frequently preferred to surgical tracheostomy. Occasionally, it needs a second dilation maneuver .Dissection of the deep cervical fascia during PDT, known as reformative PDT (re-PDT), may facilitate the procedure. This study was designed to compare re-PDT with sd-PDT in ICU patients
The synchronization between the patient and the ventilator is an essential objective during mechanical ventilation (MV). Maintaining the patient's respiratory activity during MV reduces ventilation pressures, improves oxygenation, and decreases sedation. In order to do this, the inspiratory or expiratory effort of the patient must be detected by the respirator' sensor systems, so that the assistance delivered by the respirator is coordinated with the patient's respiratory cycles. The usual systems do not actually detect the beginning of the effort but its result: variation in flow rate or pressure at the respirator circuit, which depends on the patient's respiratory mechanics and sensitivity of the sensor. This detection is currently imperfect, which generates asynchrony between the patient's needs and the assistance of the respirator. The asynchrony comprises the periods of delay between the beginning of the inspiration (or expiration) and the response of the respirator, but also of the unsuitable cycles: inspiratory efforts of the patient not detected by the respirator, or inversely triggering assistance in the absence of inspiration by the patient (self-initiation), or delivery of 2 cycles of assistance for a single inspiration (double triggering). Asynchrony is a risk factor for prolonged mechanical ventilation in adults. Adult studies have shown that patient-ventilator asynchrony is common during MV, and is associated with prolonged MV duration. An association with length of stay in intensive care and in hospital was also observed. In children, patient-ventilator synchronization is more difficult to achieve than in adults due to a higher respiratory rate and smaller current volumes. The impact of patient-ventilator asynchrony on evolution has not been studied in pediatrics. Patient-ventilator synchronization could be improved by the development of new ventilatory modes. The new NAVA (neurally adjusted ventilatory assist) ventilation mode detects the patient's breathing efforts earlier by monitoring the electrical activity of the diaphragm through the esophagus. This new mode seems to improve synchronization in children. NAVA ventilation may therefore be a step forward, but its clinical benefits remain to be seen. The objective of this study is to evaluate the impact of patient-ventilator asynchrony on the duration of mechanical ventilation in children with acute respiratory failure.
Patients undergoing extracorporeal membrane oxygenation (ECMO) are at high risk for deconditioning and functional decline. The primary aim of this study is to assess the functional impact of leg exercise during the pre-ambulation phase in patients undergoing ECMO.
Effectiveness of high flow oxygen therapy in patients with hematologic malignancy acute hypoxemic respiratory failure
Individuals with chronic liver disease develop significant muscle wasting that remains post-liver transplant. The transplant surgery additionally challenges respiratory mechanics. Respiratory muscle strength has been measured to be impaired in individuals post liver transplant. This study proposes an 8 week intervention designed to increase respiratory muscle strength and pulmonary function that we hypothesize will correlate to improved functional performance and quality of life post-liver transplant. Pre-test post-test design, that will randomize subjects into an experimental group that will receive the inspiratory muscle strengthening exercise in addition to usual post-liver transplant care and a control group that will only receive the usual post-transplant care. Up to 50 subjects will be recruited from the Post-Liver Transplant Outpatient Clinic at the Miami Transplant Institute. The subjects will have repeated measurements of respiratory muscle strength, pulmonary function, functional mobility performance, and quality of life at baseline, 4 weeks, and 8 weeks.
