Filter by:Prospective observational study of all consecutive cardio-vascular surgical patients treated with post-dilution hemofiltration with regional citrate anticoagulation as first-choice anticoagulation method. The filter life-span was assessed in the context of postoperative cardiac surgical antithrombotic prophylaxis. Reasons for termination of hemofiltration sessions were assessed. The second aim of this study was to assess the influence ACD-A based anticoagulation protocol on acid-base and ion homeostasis in cardiac surgical patients with acute renal failure.
Continuous Veno-Veinous Hemofiltration (CVVH) is a frequently used renal replacement therapy in intensive care units for patients with acute renal failure. In theory, this therapy should be continuous, 24 hours/day. However, it is wellknown that actual duration of CVVH sessions is much lower than scheduled, with frequent "circuit down-times" (between 1 to 6 hours/day). There are many reasons for premature ending of CVVH sessions (i.e. catheter dysfunction, wrong settings, low anticoagulation…), but early detection of any dysfunction may prevent (at least in part) the CVVH circuit coagulation. ICU Nurses are on the first line to manage CVVH sessions, particularly in case of alarms. High-fidelity simulation has been recently proposed for health care provider education. It has been consistently associated with large effects for outcomes of knowledge, skills, and behaviors but with moderate effects for patient related outcomes. Indeed, few studies have assess the impact of simulation on patient outcome following complexe procedures, that implies team work in addition to individual skills. In our 12-bed surgical ICU, investigators have decided to implement CVVH technics (in addition to the dialysis that we already used). Before implementing this new technic in the ICU, investigators designed this study in order assess wether a high-fidelity based ICU-nurses education program would improve the outcome of CVVH sessions, compared to the conventional education program, proposed by the CVVH manufacturer.
