Implementering av PICC-line – en kvalitativ studie av anestesisykepleieres erfaringer
2019
PICC-line, a peripherally inserted central venous catheter has been implemented by several Norwegian hospitals in recent years. Nurse Anesthetists play an important role in this process, and have been given new tasks as a result of PICC-line implementation. This study aimed to describe Nurse Anesthetists’ experiences with implementation of PICC-line in hospital. A qualitative design, the data are based on three focus groups interviews with fifteen nurse anesthetists. The interviews were analyzed using a hermeneutic approach. Being a PICC-line nurse led to a feeling of competence, independence, motivation and meaningfulness. The implementation required good structure and organization, as wel…

Antithrombotics and new interventions for venous thromboembolism: Exploring possibilities beyond factor IIa and factor Xa inhibition.
2021
Abstract Direct oral anti–activated factor X and antithrombin agents have largely replaced vitamin K antagonists as the standard of care in treatment of venous thromboembolism. However, gaps in efficacy and safety persist, notably in end‐stage renal disease, implantable heart valves or assist devices, extracorporeal support of the circulation, and antiphospholipid syndrome. Inhibition of coagulation factor XI (FXI) emerges as a promising new therapeutic target. Antisense oligonucleotides offer potential advantages as a prophylactic or therapeutic modality, with one dose‐finding trial in orthopedic surgery already published. In addition, monoclonal antibodies blocking activation and/or activ…
A late diagnosis of aortic coarctation began as an acute coronary syndrome
2014
Abstract Aortic coarctation accounts the 5%–10% of congenital heart disease. It is usually diagnosed during childhood but the postductal form is most common in adults and may be diagnosed incidentally in the context of investigation for hypertension. The age of correction is the most important factor for the relief of hypertension and long-term survival. We describe a case of a 63-year-old man, came to our emergency room for acute coronary syndrome. Cardiac catheterization with right femoral artery access was performed but for many difficulties during the introduction of catheters was therefore performed aortography that showed an interruption "a cul de sac" at the level of the descending t…
Impact of Right Ventricular Dysfunction on Outcomes After Transcatheter Edge-to-Edge Repair for Secondary Mitral Regurgitation
2021
OBJECTIVES This study sought to assess the impact of right ventricular dysfunction (RVD) as defined by impaired right ventricular-to-pulmonary artery (RV-PA) coupling, on survival after edge-to-edge transcatheter mitral valve repair (TMVR) for severe secondary mitral regurgitation (SMR). BACKGROUND Conflicting data exist regarding the benefit of TMVR in severe SMR. A possible explanation could be differences in RVD. METHODS Using data from the EuroSMR (European Registry on Outcomes in Secondary Mitral Regurgitation) registry, this study compared the characteristics and outcomes of SMR patients undergoing TMVR, according to their RV-PA coupling, assessed by tricuspid annular plane systolic e…
Comparison of Arterial and Venous Blood Flow Between Patients with Pressure Dressing or a New Hemostatic Puncture Closure Device After Cardiac Cathet…
1997
The aim of the study was to compare arterial and venous flow volume in the punctured leg in patients given a conventional pressure dressing and those given a new hemostatic puncture closure device (Angio-Seal) after cardiac catheterization. We prospectively measured blood flow in 25 patients with pressure dressing (group A) and 25 patients with Angio-Seal (group B) after cardiac catheterization. Duplex sonographic measurements were performed at the superficial femoral artery and vein of the punctured leg. In group A measurements were performed before catheterization, during pressure dressing, and after removal of pressure dressing. In group B we performed the measurements before catheteriza…
Is cell salvage safe in liver resection? A pilot study
2007
Abstract Study Objective To investigate the quality of cell salvaged (CS) blood in patients undergoing hemihepatectomy (study group) and compare it with CS-blood from aortic surgery (control group). Design Observational study. Setting Operating room in a university hospital. Measurements 6 patients undergoing hemihepatectomy or aortobifemoral bypass with intraoperative blood loss of more than 800 mL. Samples were drawn from the central venous catheter, from the reservoir of a CS recovery system, and from the processed blood in each patient to determine interleukin (IL)-6, IL-8, IL-10, tumor necrosis factor (TNF), complement C3a, and the terminal complement complex C5b-9. Microbiological ana…
Requirements on resolution of digital imaging equipment in the cardiac catheterization laboratory.
1988
We evaluated the requirements on spatial resolution of digital imaging equipment in the cardiac catheterization laboratory. Fifty cinefilms of the heart as the biological object and one film of a lead-ladder-pattern as an objective test were used. The patient films were examined for the visibility of the left ventricular angiogram, coronary arterial tree, coronary artery lesions, branching of septal arteries and the number of septal arteries. All films were viewed three times: with a 625 line TV-system, with a 1249 line TV-system and with a cineprojector. It was found that two application areas with different demands on the spatial and temporal resolution can be distinguished: 1) low spatia…
Advanced Protocol for Three-Dimensional Transesophageal Echocardiography Guidance Implementing Real-Time Multiplanar Reconstruction for Transcatheter…
2019
Transcatheter direct annuloplasty has been introduced as a novel interventional treatment option for severe mitral valve regurgitation. Until now, only one direct annuloplasty device (Edwards Cardioband) has been commercially available, being implanted in more than 250 patients worldwide. Yet this procedure poses greater challenges regarding optimal fluoroscopic and echocardiographic guidance compared with edge-to-edge repair: correct localization and orientation of the anchors upon penetration into the fibrous mitral annulus tissue and the basal left ventricular myocardium are preconditions for an optimal result and essential to avoid damage of the neighboring structures (atrioventricular …
Feasibility of a MPR-based 3DTEE guidance protocol for transcatheter direct mitral valve annuloplasty.
2020
Objectives Several interventional approaches have been established for the treatment of severe mitral regurgitation (MR) in patients at elevated risk for surgery. Direct annuloplasty is a relatively novel option in transcatheter mitral valve repair dedicated to reverse pathology in specific subsets of MR. With regard to echocardiographic guidance, this procedure presents with higher efforts in comparison with edge-to-edge therapy to enable safe and exact positioning of the device's anchors; evidence on optimal peri-interventional imaging is sparse. We tested a specific 3D-echo-guidance protocol implementing single-beat multiplanar reconstruction (MPR) and evaluated its feasibility. Methods …
