Filter by:Many medical procedures are done with the aid of ultrasound imaging, but they remain difficult to learn and perform. This study will use augmented reality technology for making these procedures potentially more intuitive, easier, more precise, and safer.
Liver cirrhosis patients in Intensive Care present intra-abdominal hypertension and this is an independent risk factor for increased organ disfunction and mortality. Patients will be randomized into intermittent or continuous passive paracentesis and the clinical results of these two strategies for preventing and treating intra-abdominal hypertension will compared.
Paracentesis is a bedside procedure in which a needle is inserted into a patient's peritoneum in order to obtain ascitic fluid. This is a safe bedside procedure with very low risks of complications that is usually performed using physical exam maneuvers to determine the site of needle insertion. Point of care ultrasound (POCUS) technology has improved the safety of central venous catheter insertion and thoracentesis, yet the data on safety in paracentesis is equivocal. In a practical study, we aim to determine if POCUS will change the needle insertion site over the traditional anatomic landmarking method. Operators will landmark for paracentesis using conventional physical exam and then utilize POCUS to determine if there is a more optimal site. The primary endpoint will be whether POCUS yielded a change in the needle insertion site, as defined by a location greater than 5cm from the anatomic site, at least 20% of the time. The results will further our understanding of POCUS in improving procedural safety, thereby adding to the currently limited literature on this topic. Furthermore, this study will inform residency training programs about the utility in POCUS training for paracentesis and may advocate for the availability of POCUS devices to physicians performing this procedure.
The hypothesis is that the Alfapump® strategy would be more effective in terms of QALYs generated , and that the cost of Alfapump® device and its implantation will be totally or partially offset by the reduction in the number of evacuating parentheses performed and the reduction in the number of complications in patients with refractory ascites awaiting liver transplantation or not. On the other hand, given the difference in the clinical profiles of these two populations (whether or not they are awaiting transplantation), these two populations will be study separately Evaluation of the medical-economic impact at 1 year of the two therapeutic strategies: implantation of Alfapump® versus repeated evacuating paracentesis in cirrhotic patients with refractory ascites without scheduled liver transplantation.
This observational study evaluates the clinical, biochemical and haemodynamic effects of large-volume paracentesis (LVP) in 50 patients with and without signs of inflammation
