193 Clinical Trials for Various Conditions
This is a clinical trial to compare the oxygenation and ventilation performance between manual ventilation and mechanical ventilation when transporting cardiac patients to the ICU.
Mechanical ventilation is a commonly used life-saving hospital procedure for patients with severe breathing difficulty. Some patients have difficulty separating from the ventilator and need to be removed gradually. This process is called ventilator weaning. It is not known what is the best way to wean patients from the ventilator. In this study, the investigators will compare two commonly used ventilator weaning strategies and compare their success. One ventilator strategy, the Pressure Support Ventilation weaning (PSV), combines 12 hours ventilator weaning with 12 hours rest on the ventilator. This strategy is faster with an anticipated weaning in 2 weeks. The other strategy, the Therapist implemented Patient Specific weaning (TIPS), gradually lowers support and weans in 3 weeks. Patients admitted to Barlow Respiratory Hospital (BRH) for ventilator weaning will be asked to participate in this study within 72 hours of hospital admission. Participants will undergo a spontaneous breathing trial (SBT) to assess your ability to breathe while receiving minimal or no ventilator support. Patients who pass SBT will be eligible for cool aerosol trials (humidified, oxygenated air without positive pressure mechanical ventilation). Participants who fail SBT within 24 hours will be eligible for the study. Participants will be randomized to receive PSV or TIPS ventilator weaning. The investigators will collect clinical, laboratory and mechanical ventilator information throughout the study period. Ventilator weaning success will be compared at day 30. The study will not interfere with any components of clinical care but the study investigators will be allowed to change the ventilator weaning strategy from PSV to TIPS, if a participant is unable to tolerate PSV weaning.
Many extremely premature infants, born before 28 weeks' gestation age, require immediate help with breathing after birth. Positive pressure ventilation (PPV) using a device called a T-piece resuscitator is a common method. PPV is needed to establish proper lung function, improve gas exchange, and encourage the infant to breathe spontaneously. However, T-piece resuscitators have limitations, like a lack of visual feedback and variable settings, which may result in reduced effectiveness of PPV. Improving PPV effectiveness may reduce the need for more invasive procedures, such as intubation, which pose an increased risk of complications and death for these fragile infants. A novel approach, that may overcome the above limitations and deliver PPV with precise settings through a nasal mask, is to use a ventilator to deliver PPV (V-PPV) using a respiratory mode called nasal intermittent positive pressure ventilation (NIPPV). While NIPPV is commonly used in neonatal intensive care units to support breathing in premature infants, the impact of V-PPV use during immediate post-birth stabilization needs to be studied. Preliminary data from our recent single-center study confirmed the feasibility of using V-PPV for resuscitation of extremely premature babies and indicated its potential superiority with a 28% decrease in the need for intubation compared to historical use of T-piece. This promising innovation may enhance outcomes for these vulnerable infants by refining the way we provide respiratory support in their critical first moments. The research objective is to compare the clinical outcomes of extremely premature infants receiving manual T-piece versus V-PPV during immediate post-birth stabilization. The primary aim is to evaluate the impact of V-PPV on major health complications or death. This study seeks to provide insights into improving the care and outcomes of these infants during a critical stage of transition from fetus to newborn.
Ventilator associated events (VAE) is a quality metric defined by 48 hours of stability followed by 48 hours of escalation of ventilator settings within the ICU. VAE have been associated with poor outcomes and increases the cost of care, yet is not easy to avoid. Operationalizing all the standards of care known to improve outcomes of those requiring mechanical ventilation in the critical care environment requires a comprehensive approach. ICU teams are encouraged to follow best practice protocols to help liberate and prevent VAEs. Yet, compliance with protocols in most ICUs is suboptimal for multiple reasons. With the advent of computerized mechanical ventilators capable of streaming data from breath to breath and biomedical integration systems (BMDI) such as Capsule (UTMB's BMDI system), software systems have been developed to help identify variances in the standard of care. Automation in near real-time ventilator data feedback has been shown to reduce the incidences of VAEs. This quality improvement project will leverage Vyaire's Respiratory Knowledge Portal (RKP) to collect and store meaningful data regarding ventilator-associated events (VAE), alarm policy compliance, ventilator weaning, and lung protective analytics. Goals: 1. To collect quality metrics utilizing RKP from patients requiring mechanical ventilation over a 3-4-month period for a retrospective baseline analysis. 2. Provide the RKP tool to the ICU team to determine if the use of RKP's webportal and Messenger Zebra phone app improves quality of mechanical ventilation and outcomes. 3. To determine a return on investment (ROI) for a software system like RKP.
Modern intensive care units (ICUs) are increasingly adopting newer modes of mechanical ventilation such as adaptive pressure control (APC) modes but there are limited data available regarding risks and benefits of newer modes versus traditional ventilation modes. APC can inadvertently deliver high tidal volumes, which maybe harmful. High tidal volumes may be unrecognized by the provider, due to the complexities of ventilator algorithms and patient interactions. The objective of this aim is to identify risk factors for excess tidal volumes in patients on adaptive pressure control.
The goal of this pragmatic cluster-randomized crossover trial is to test if less unnecessary antibiotics are prescribed when the lab reports respiratory culture test results in a specific way for patients who have respiratory cultures obtained, but do not meet clinical criteria for ventilator associated pneumonia (VAP). The main question it aims to answer is: Does a modified culture reporting intervention reduce unnecessary antibiotics for ventilated patients in the intensive care unit (ICU)? Researchers will compare antibiotic use outcomes between eligible patients whose test results are communicated using the modified reporting and those with standard reporting of results.
This is an early phase, proof-of-concept clinical trial assessing the safety and feasibility of non-invasive spinal cord stimulation to prevent respiratory muscle atrophy in mechanically ventilated ARDS patients. The investigators will recruit 10 elective surgery patients (surgery cohort) and 10 ARDS patients (ARDS cohort) for this study. A non-invasive, alpha-prototype Restore Technology stimulator using hydrogel surface electrodes will be used to stimulate the spinal cord at the cervical or thoracic level.
The objective of the study is to pilot a parent-to-parent coaching model with experienced family members of children with Invasive Mechanical Ventilation (IMV) as parent coaches.
Respiratory Therapists (RTs) have difficulty maintaining compliance with protocols and making efficient handoff communication. This project will evaluate the effectiveness of an electronic tool that will display a dashboard of key information on all the RTs patients and provide reminders that indicate whether evidence-based practice protocols are being followed. In addition, it will collect data from medical devices and the EMR and outline key information in the appropriate format to help standardize and improve handoff communication. The study will first collect blind baseline data for comparison with protocol adherence and silently evaluate shift change handoffs. In the second stage, the electronic tool will be installed and used to evaluate whether protocol compliance and shift change handoff is improved.
The purpose of this study is to see if the amount of antibiotics given for ventilator-associated pneumonia (VAP) can be decreased in order to reduce the risk of adverse effects associated with antibiotics, while at the same time ensuring the participant's safety.
This is a prospective pilot/feasibility trial of a bundled diagnostic stewardship intervention at the level of the microbiologic testing pathway in ventilator-associated pneumonia (VAP). The study utilized a pre/post design and was initially registered as a single-arm trial because the study intervention could only be applied prospectively to a single group (all patients hospitalized in study ICUs requiring ventilation during the trial intervention period). The study objectives are to safely and effectively reduce antibiotic overuse and its attendant hazards (adverse drug events, Clostridioides difficile diarrhea and generation of multidrug-resistant organisms) among mechanically-ventilated patients. Participating ICUs will have the following three modifications made in their respiratory culture workflows for mechanically-ventilated patients: 1) providers will be required to select a valid indication for respiratory culture performance (worsening ventilator requirements, purulent sputum production, and/or new radiographic infiltrate on chest imaging); 2) respiratory cultures will be preferentially obtained via bronchoscopic or nonbronchoscopic BAL (by respiratory therapists) rather than via endotracheal aspiration; and 3) BAL samples will be sent for cell count and differentials, and respiratory culture results will not be released for samples with \<50% neutrophils. The study will carefully monitor adherence to study interventions, ICU-specific antibiotic utilization rates, and important safety metrics including rates of mortality, ventilator-dependence and ventilator-associated events. The trial hypotheses are: * Implementation of a VAP diagnostic stewardship bundle will be successfully implemented without significant increases in mortality or ventilator-associated events. * Implementation of a VAP diagnostic stewardship bundle will be associated with a reduction in ICU-specific antibiotic utilization rates
ASOP is a prospective cohort study comparing three methods for assessing risk of self-induced lung injury in patients with acute respiratory failure being managed with pressure-support ventilation. We will describe the relationship between three different assessment methods for risk of self-induced lung injury and compare them to a gold standard measurement.
The purpose of this study is to test whether or not the use of a low volume ventilator in an anesthesia machine reduces anesthetic costs significantly as compared to other high volume machines. The study will compare the a low-flow anesthesia machine to a traditional anesthesia machine during routine elective general surgery in patients with ASA ratings of 1-2 under general anesthesia receiving standard care.
The mortality rates associated with COVID-19 related ARDS (COVIDARDS) have varied from observational reports from around the world. This has ranged from 44% (28 day mortality) in the UK to 36% (28 day mortality from ICU admission) in Italian studies, to 32% (all-cause 28 day mortality) in Spain. Predictive models have identified risk factors for COVID-19 hospitalized patients' mortality to include male sex, obesity, age, obesity, comorbidities including chronic lung disease and hypertension, as well as biomarkers including high levels of D-Dimer, LDH and CRP. In addition, practice patterns, such as drugs that were administered, timing of mechanical ventilation and adherence to established lung protective ventilation protocols are known to be variable across sites and have changed over time. The investigators propose to analyze outcomes for patients with COVIDARDS within the NorthCARDS dataset (a dataset of over 1500 patients with COVID-19 related ARDS across the Northwell Health System in the NYC metropolitan region and Long Island, NY) to understand differences in hospital survival and in the time to liberation from mechanical ventilation, specifically looking at the associations between baseline patient factors, changes in biomarkers, respiratory function and hemodynamics over time, and treatments administered. The analyses will be based on three hypotheses: H.1. Worsening trajectories of: oxygenation index (OI), respiratory system compliance (C), and inflammatory markers will be associated with lower hospital survival. H.2. Higher duration of deep sedation and paralytics will be associated with greater time to liberation from mechanical ventilation. This risk will be increased in patients with worsening trajectories of OI, C, and inflammatory markers over time. H.3. Type of mechanical ventilator, specifically the time on portable mechanical ventilator, is associated with hospital mortality and with inability to liberate from mechanical ventilator despite controlling for risk factors of changes in OI, C and Inflammatory markers over time, and the use of paralytics and deep sedation.
The goal of this study is to determine what percent of severe patient-ventilator asynchrony is detected in mechanically ventilated patients in the adult ICU and to determine delays in detecting those asynchronies by the staff that were correctly identified, and whether asynchrony status recorded during intermittent assessments by respiratory therapists is representative of periods in between such assessments.
The purpose of this study is to develop a safe, easily scalable, and simple method to split a single ventilator for use amongst two or more patients, thus serving as a capacity bridge to save patient lives until manufacturers can produce enough ventilators.
The investigators will develop, refine and pilot a highly-realistic simulation program that will allow caregivers opportunities to manage critical situations as it pertains to a medically complex child dependent on tracheostomy with or without home ventilation. The investigators hope to demonstrate that the use of highly realistic simulation training will improve hospital utilization as caregivers will have a more realistic understanding of clinical and equipment-related emergencies that may occur outpatient.
There is a fundamental gap between the discovery of proven-effective intensive care unit (ICU) sedation, mechanical ventilation, mobility, and symptom management strategies and approaches that can equip ICU providers with the skills necessary to reliably adopt these interventions in everyday practice. Until this gap is filled, the millions of patients with heart, lung, and blood disorders admitted to ICUs annually will remain at risk for avoidable physical, mental, and cognitive health impairments that may persist for months to years after hospital discharge. In the proposed study, the investigative team will continue their partnership with the Society of Critical Care Medicine's (SCCM's) ICU Liberation Collaborative. Guided by the Consolidated Framework for Implementation Research, the overall objective of the Determinants of Implementation Success Coordinating Ventilator, Early Ambulation and Rehabilitation Efforts in the ICU (DISCOVER-ICU) study is to develop multilevel implementation strategies to enhance sustainable adoption of the ABCDEF (Assess, prevent, and manage pain and delirium, both spontaneous awakening and breathing trials, choice of sedation, early mobility, family engagement) bundle in routine ICU practice. Using a multiphase, sequential, mixed-methods design, this study has three specific aims: 1) estimate the effects of patient-level characteristics on ABCDEF bundle adoption; 2) examine unit-level variation in ABCDEF bundle adoption and associated provider- and organization-level characteristics; and 3) determine which implementation strategies result in the greatest adoption of the ABCDEF bundle. Existing deidentified data will be obtained from \>15,000 patients, \>5,000 interprofessional ICU team members, and 68 hospitals participating in the ICU Liberation Collaborative to achieve specific aims 1 and 2. For specific aim 3, data collection will be extended using interprofessional ICU team surveys, a modified Delphi process, and concept mapping to achieve greater understanding of implementation strategies that prove most effective for ABCDEF bundle adoption. Results of this work will directly lead to the development of implementation strategies that are adaptable, responsive to community needs, and account for the cultural and organizational factors necessary to increase ABCDEF bundle adoption. These implementation strategies will then be tested in a future cluster randomized hybrid II implementation effectiveness trial.
The primary aim of this study is to evaluate the CleanSweep™ Closed Suction System on time to first successful spontaneous breathing trial in mechanically ventilated patients in the medical intensive care unit. Secondary aims of this study are to evaluate the use endotracheal tube sweeping compared to closed suctioning effect on length of mechanical ventilation, length of ICU stay, length of total hospital stay, and occurrence of ventilator-associated events.
Researchers are looking at two different types of breathing tubes to see if one is better than the other at preventing pneumonia. One of the tubes has a design features to prevent leakage of fluids from the mouth and the back of the throat into the lower airways and lungs. This is important since leakage of small amounts of fluid into the lungs may lead to pneumonia. The other tube is the standard tube used at most hospitals. The hypothesis is that the use of a breathing tube that reduces fluid leakage into the lungs will reduce the risk of developing pneumonia and improve quality of life and cognitive function, compared to the standard tube. The study will also look at the safety of the modified breathing tube, compared to the standard tube.
We intend, with this study, to prove that blocking the molecular mechanisms whose blockade prevents VIDD in animals, will indeed prevent the development of VIDD in humans as well. We believe that this evidence will serve as the required basis for proceeding with large, ICU-based clinical trial(s) of a drug to prevent VIDD.
This study will be used to evaluate and observe the overall performance and controls of the Helix ventilator. Pressure and flow data between participants' current devices and the Helix ventilator will be assessed in either invasive or non-invasive ventilation. To evaluate ventilator performance, pressure and waveform data will be assessed as well. Also, patient and caregiver feedback will be captured. The target population is infants to adults weighing more than 5kg. Participants will be recruited by Boston Children's Health Physician's Group. Up to thirty participants will be enrolled in the study.
Patients admitted to the ICU with diagnosis of sepsis and requiring mechanical ventilation for at least 24-hours and receiving enteral or parenteral nutrition will be prospectively randomized to one of two arms. Patients allocated to the estimated energy expenditure group will receive nutrition with caloric intake calculated based on the Penn State equation. Patients randomized to the measured group will receive nutrition with caloric intake calculated based on IC measurement present in the GE ventilator. Patients in the estimated group will have IC performed, but these data will not be used for prescription of nutrition. An equal number of beds within the ICU will be allocated to the measured group and the estimated group. The primary objective is to assess whether the utilization of indirect calorimetry for caloric goal calculation results in improvement in muscular structure, and consequent reduction of mechanical ventilation duration in patients with sepsis in comparison to utilizing the Penn State estimation equation for caloric goal calculation. The secondary objective is to assess whether the utilization of indirect calorimetry for caloric goal calculation results in improved adequacy of nutritional delivery in comparison to the adequacy of nutritional delivered when utilizing the Penn State estimation equation. Adult patients (\> 18 years of age) admitted to the hospital with diagnosis of sepsis, and who require mechanical ventilation during hospitalization will be considered. Patients newly ventilated for at least one day but less than three days will be included in the study. Informed consent will be obtained from the legal authorized representative (LAR).
This study is a Phase II controlled clinical trial that will obtain comprehensive, serial assessments of respiratory muscle strength and architecture to understand the evolution of ventilator-induced respiratory muscle weakness in critically ill children, and test whether a novel computer-based approach (Real-time Effort Driven ventilator management (REDvent)) can preserve respiratory muscle strength and reduce time on MV. REDvent offers systematic recommendations to reduce controlled ventilation during the acute phase of MV, and uses real-time measures from esophageal manometry to adjust supported ventilator pressures such that patient effort of breathing remains in a normal range during the ventilator weaning phase. This phase II clinical trial is expected to enroll 276 children with pulmonary parenchymal disease, anticipated to be ventilated \> 48 hrs. Patients will be randomized to REDvent-acute vs. usual care for the acute phase of MV (interval from intubation to first spontaneous breathing trial (SBT)). Patients in either group who fail their first Spontaneous Breathing Trial (SBT), will also be randomized to REDvent-weaning vs. usual care for the weaning phase of MV (interval from first SBT to passing SBT). The primary clinical outcome is length of weaning (time from first SBT until successful passage of an SBT or extubation (whichever comes first)). Mechanistic outcomes surround multi-modal serial measures of respiratory muscle capacity (PiMax), load (resistance, compliance), effort (esophageal manometry), and architecture (ultrasound) throughout the course of MV. Upon completion, this study will provide important information on the pathogenesis and timing of respiratory muscle weakness during MV in children and whether this weakness can be mitigated by promoting more normal patient effort during MV via the use of REDvent. This will form the basis for a larger, Phase III multi-center study, powered for key clinical outcomes such as 28-day Ventilator Free Days.
As the general population ages and technology advances, many who suffer from catastrophic critical illness (i.e. septic shock, respiratory failure, Acute Respiratory Disease Syndrome) survive only to find themselves severely physically debilitated and compromised from a pulmonary standpoint, requiring assistance from a mechanical ventilator in order to breath. Oftentimes, these patients require a long course of physical rehabilitation and ventilator support. These patients frequently remain ventilator dependent for greater than 3 weeks, and are thus referred to as requiring prolonged mechanical ventilation (PMV). Older patients are at significantly higher risk for requiring PMV for reasons that are not entirely clear, but which may include physical deconditioning, impaired cardiopulmonary physiology, and cognitive or behavioral disturbances. The purpose of this study is two fold: 1. to characterize the functional phenotype of ventilator dependent, and recently ventilated patients with respect to general strength, endurance, balance, and pulmonary functioning and body composition. 2. To pilot test a rehabilitation protocol that targets improving this populations disabilities through exercises focused on improving strength, endurance, balance, and pulmonary functioning.
The proposed study is an important, under-investigated area of ICU care for terminally ill patients undergoing terminal ventilator withdrawal. The proposed research has relevance to public health because an algorithmic approach to the ventilator withdrawal process will enhance clinicians' ability to conduct the process while assuring patient comfort, using opioids and/or benzodiazepines effectively.
Breath samples from patients with Ventilator Acquired Pneumonia (VAP) will be analyzed to identify Volatile Organic Compounds (VOC) that have been specifically associated with VAP in previous animal models. Primary outcome measures will include the assessment of the zNose Diagnostic Breath Analysis System in the early detection of VOC's associated with VAP.
This is a prospective study with three specific aims: (1) To convene a consensus conference to develop a guideline for antibiotic use in infants (age \< 3 yrs) with suspected ventilator-associated infection; (2) To evaluate outcomes before and after implementation of the antibiotic guideline; (3) To evaluate changes in the tracheal microbiome over the course of mechanical ventilation
The primary objective of this study is to determine whether neuromuscular electrical stimulation applied to the abdominal wall muscles in synchrony with exhalation can increase the strength of the respiratory muscles in prolonged mechanical ventilation patients.
This pilot study tests the feasibility of using a computerized ventilator management protocol seeking to encourage lung protective ventilation during the acute phase of ventilation, and esophageal manometry based titration of ventilator settings during the weaning phase of ventilation, for children with acute respiratory failure. The investigators hypothesize that such an approach will reduce time on mechanical ventilation, largely by preserving diaphragm muscle function.
