2 Clinical Trials for Various Conditions
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.
The purpose of this study is to compare airway pressure release ventilation (APRV) to conventional mechanical ventilation (MV) in patients with acute lung injury (ALI) to determine if APRV can reduce agitation, delirium, and requirements for sedative medications. We will also compare markers of inflammation in the blood and lung to determine if APRV reduces ventilator-induced lung injury (VILI), compared to conventional mechanical ventilation. The proposed study is a randomized, crossover trial. We plan to enroll 40 patients with ALI and randomize to APRV or conventional MV for 24 hours. After this time the patients will be switched to the alternative mode of ventilation (MV or APRV) for another 24 hours. To assess breathing comfort, at the end of each 24-hour period we will measure the amounts of sedative and analgesic medications used. We will also measure the concentrations of markers of inflammation in the blood and lung as measures of VILI. Finally, throughout the study we will compare the adequacy of gas exchange with APRV compared to conventional MV.
