NCT04648657
The investigators suppose that lung sliding could be reduced in the same lung region moving from less ventilated to overinflated condition. This is supported by theoretical arguments by some authors but so far it has not been demonstrated. The investigators suppose that speckle tracking applied to LUS is able to demonstrate a reduction or abolition in pleural sliding when lung tissue is overinflated by higher PEEP after lung recruitment maneuver. The overinflation is diagnosed by Electric Impedance Tomography (EIT) and mechanical respiratory measurements (reduction in compliance as ratio between tidal volume over difference between plateau pressure and PEEP) and localized by EIT.
NCT02255838
Flexible bronchoscopes are typically reusable and therefore need high level disinfection to prevent inadvertent spread of microbial pathogens from patient to patient. The process of disinfection is time consuming and expensive. Moreover, a bronchoscope being processed may not be readily available for another patient. One solution to this problem was to use a single use disposable sheath that covers a flexible bronchoscope protecting all surfaces of the bronchoscope.(Colt, Beamis, Harrell, \& Mathur, 2000). Another way to eliminate potential hazards with a reusable bronchoscope is the use of a disposable bronchoscope. Such a disposable bronchoscope has been developed (Ambu aScope, Ambu, Glen Burnie, MD) and has been used successfully for intubations in manikins(Scutt et al., 2011) and patients. (Kristensen \& Fredensborg, 2013; Pujol, López, \& Valero, 2010; Tvede, Kristensen, \& Nyhus-Andreasen, 2012). Further advancement in the imaging and handling of this disposable flexible bronchoscope now allows for the purpose of bronchoscopy and broncho-alveolar lavage in critically ill patients with pulmonary compromise. (FDA approval: 05-11-2013 date) The aim of the study is to compare image clarity, suction capacity, and handling performance of a reusable flexible bronchoscope to the disposable flexible bronchoscope. In addition, the investigators intend to perform a cost analysis.
