RESUMEN
Intravascular catheters are inserted into almost all critically ill patients. This review provides up-to-date insight into available knowledge on epidemiology and diagnosis of complications of central vein and arterial catheters in ICU. It discusses the optimal therapy of catheter-related infections and thrombosis. Prevention of complications is a multidisciplinary task that combines both improvement of the process of care and introduction of new technologies. We emphasize the main component of the prevention strategies that should be used in critical care and propose areas of future investigation in this field.

Tunnelled central venous access devices (CVADs) are defined as any intravenous multipurpose catheters placed within the central veins for use in haemodialysis and administration of blood products or chemotherapy in oncology and haematological conditions. Frequent complications include thrombosis and catheter-related infection, which may lead to significant adverse patient outcomes. Once thrombosis is suspected correction should be attempted empirically with thrombolytic agents. Commonly available thrombolytic agents in the UK include urokinase (Syner-Kinase) and alteplase (Cathflo). It is well recognised that urokinase usage differs widely and concerns were raised by clinicians about the variation of dose regimens nationally. The objective of the CVAD Focus Group was to address this issue and offer guidance in the management of suspected thrombosis of CVAD with urokinase using two algorithms for renal and non-renal dysfunctional CVAD and to audit prospectively the outcomes of intervention.

AIMS AND OBJECTIVES: This study aimed at developing and implementing evidence-based patient and family education on oral anticoagulation therapy. BACKGROUND: The number of persons with chronic diseases who live at home is increasing. They have to manage multiple diseases and complex treatments. One such treatment is oral anticoagulation therapy, a high risk variable dose medication. Adherence to oral anticoagulation therapy is jeopardised by limited information about the medications, their risk and complications, the impact of individual daily routine and the limited inclusion of family members in education. Hence, improved and tailored education is essential for patients and families to manage oral anticoagulation therapy at home. DESIGN AND METHODS: A community-based participatory research design combined with the Precede-Proceed model was used including a systematic literature review, posteducation analysis, an online nurse survey, a documentation analysis and patient/family interviews. The study was conducted between April 2010-December 2012 at a department of general internal medicine in a teaching hospital in Switzerland. Participants were the department's nursing and medical professionals including the patients and their families. RESULTS: The evidence-based patient and family education on oral anticoagulation therapy emerged comprising a learning assessment, teaching units, clarification of responsibilities of nurse professionals and documentation guidelines. CONCLUSION AND CLINICAL RELEVANCE: The inclusion of the whole department has contributed to the development and implementation of this evidence-based patient family education on oral anticoagulation therapy, which encompasses local characteristics and patient preferences. This education is now being used throughout the department.

Over the past decades, secondary prevention of cardiovascular (CV) disease has improved and considerably reduced mortality rates. However, there remains a high-rate of new or recurrent CV events in those with established atherosclerotic vascular diseases. Although most of the prevailing therapies target the conventional risk factors, there is notable interindividual heterogeneity in adaptation to risk factors and response to therapies, which affects efficacy. It is desirable to have a methodology for directly assessing the functional significance of atherogenesis, and for managing individual patients based on their comprehensive vascular health. Endothelial function plays a pivotal role in all stages of atherosclerosis, from initiation to atherothrombotic complication. Endothelial function reflects the integrated effect of all the atherogenic and atheroprotective factors present in an individual, and is therefore regarded as an index of active disease process and a significant risk factor for future CV events. Moreover, improvement in endothelial function is associated with decreased risk of CV events, even in the secondary prevention setting. The introduction of endothelial function assessment into clinical practice may trigger the development of a more tailored and personalized medicine and improve patient outcomes. In this review, we summarize current knowledge on the contribution of endothelial dysfunction to atherosclerotic CV disease in the secondary prevention setting. Finally, we focus on the potential of an endothelial function-guided management strategy in secondary prevention.

BACKGROUND: Successful management of warfarin, new anti-thrombotic agents and self-monitoring devices requires that health care professionals effectively counsel and educate patients. Previous studies indicate that health care professionals do not always have the knowledge to provide patients with the correct information. AIMS: The purpose of this study was to investigate European cardiovascular nurses' knowledge on the overall management of anticoagulation therapy and examine if this knowledge was influenced by level of education and years in clinical practice. METHODS: A questionnaire including 47 items on practice patterns and knowledge on warfarin, new anticoagulants, warfarin-drug and warfarin-food interactions, and self-management of International Normalized Ratio (INR) was distributed to the attendants at a European conference in 2012. RESULTS: The response rate was 32% (n=206), of whom 84% reported having direct patient contact. Warfarin was the most common used oral anticoagulation in daily practice. One third offered their patients both patient self-testing and patient self-management of INR. The mean total score on the knowledge questions was 28±6 (maximum possible score 53). Nurses in direct patient care had a higher mean score (p=0.011). Knowledge on warfarin and medication-interactions were low, but knowledge on warfarin-diet interactions and how to advise patients on warfarin as somewhat better. CONCLUSION: European cardiac nurses need to improve their knowledge and practice patterns on oral anticoagulation therapy. This area of knowledge is important in order to deliver optimal care to cardiac patients and to minimise adverse effects of the treatment.

Patient assessment and the appropriate management of long-term central venous access devices are essential to diminishing the potential for complications. When complications do occur, they tend to be the consequence of a series of events. Recognising problems at an early stage means they can be addressed sooner and improves the chances of resolving them without any long-term consequences.

The objective of this study was to use trauma registry data to describe the number and characteristics of patients 21 years or younger receiving thromboprophylaxis with low-molecular-weight heparin at 2 pediatric and 2 adult level 1 trauma centers. Among 706 patients, the average age was 18.5 years, and 94.6% were hospitalized at adult centers. The most common injuries were lower extremity fractures (35.6%) and head injuries (20.4%). Major bleeding was reported in 3 patients (0.4%), and thrombotic events were reported in 15 patients (2.1%). Despite a lack of scientific evidence, low-molecular-weight heparin prophylaxis is being used in young trauma patients (primarily those 14 years or older). Prospective multicenter studies are needed to accurately describe the risks and benefits of low-molecular-weight heparin prophylaxis in young trauma patients, thereby identifying those who truly benefit from this intervention.

The use of central venous access devices (CVADs) is becoming more common in hospitals and the community. Incorrect tip placement is a common complication of CVAD insertion carried out at the bedside, and can lead to local inflammation and thrombosis. The literature recommends that a CVAD tip should be in the lower third of the superior vena cava. Anyone inserting a CVAD needs to take account of body position changes that may cause a tip to move. There are many tools and systems nurses can use to aid tip positioning, including taking body measurements, using body landmarks and electrocardiograms (ECGs). Tip position must be checked on a chest X-ray. There are several ways to determine tip postion and electromagnetic catheter tip guidance machines are being developed in the USA, which can record the position of a tip with greater accuracy. Nurses inserting CVADs at the bedside must appreciate the risks that incorrect or suboptimal tip position pose to the patient.

Thrombosis is the leading cause of access dysfunction and is expensive to treat. In 2011, only 10 AV access capable patients in our center were placed on a bridge catheter because of our ability to assess health and proactively use angioplasty to keep it open. Surveillance also helped us follow the progression of new fistula maturation and helped us decide on early intervention to prevent total, access failure. The Sparrow Center documented successful results with the selection of a new surveillance system that dramatically improved the quality of patient care and financial viability of the center. For dialysis center staffs looking for ways to operate more efficiently and at the same time reduce the incidence of vascular access complications caused by thrombosis, a data-driven surveillance device along with clinical monitoring protocols seems to provide a cost effective approach to addressing this critical area of patient care.

BACKGROUND: Warfarin nomograms to guide dosing have been shown to improve control of the international normalized ratio (INR) in the general outpatient setting. However, the effectiveness of these nomograms in hemodialysis patients is unknown. We evaluated the effectiveness of anticoagulation using an electronic warfarin nomogram administered by nurses in outpatient hemodialysis patients, compared to physician directed therapy. METHODS: Hemodialysis patients at any of the six outpatient clinics in Calgary, Alberta, treated with warfarin anticoagulation were included. Two five-month time periods were compared: prior to and post implementation of the nomogram. The primary endpoint was adequacy of anticoagulation (proportion of INR measurements within range ± 0.5 units). RESULTS: Overall, 67 patients were included in the pre- and 55 in the post-period (with 40 patients in both periods). Using generalized linear mixed models, the adequacy of INR control was similar in both periods for all range INR levels: in detail, range INR 1.5 to 2.5 (pre 93.6% (95% CI: 88.6% - 96.5%); post 95.6% (95% CI: 89.4% - 98.3%); p = 0.95); INR 2.0 to 3.0 (pre 82.2% (95% CI: 77.9% - 85.8%); post 77.4% (95% CI: 72.0% - 82.0%); p = 0.20); and, INR 2.5 to 3.5 (pre 84.3% (95% CI: 59.4% - 95.1%); post 66.8% (95% CI: 39.9% - 86.0%); p = 0.29). The mean number of INR measurements per patient decreased significantly between the pre- (30.5, 95% CI: 27.0 - 34.0) and post- (22.3, 95% CI: 18.4 - 26.1) (p = 0.003) period. There were 3 bleeding events in each of the periods. CONCLUSIONS: An electronic warfarin anticoagulation nomogram administered by nurses achieved INR control similar to that of physician directed therapy among hemodialysis patients in an outpatient setting, with a significant reduction in frequency of testing. Future controlled trials are required to confirm the efficacy of this nomogram.

Uma das complicações mais frequentes da fístula arteriovenosa (FAV) para hemodiálise é o desenvolvimento de um aneurisma. A formação de aneurismas geralmente decorre de um enfraquecimento da parede venosa devido às repetidas punções, e sua rotura causa hemorragia intensa que pode levar à morte. Descrevemos o caso de uma paciente com dois aneurismas saculares de FAV, tratados através de aneurismorrafia, detalhando a técnica cirúrgica utilizada e a evolução pós-operatória. A técnica de rafia simples da parede constitui uma boa alternativa no reparo da parede da FAV quando o aneurisma é de curta extensão, evitando a colocação de um material protético e a confecção de duas anastomoses.
One of the most common complications of arteriovenous fistulas (AVF) is aneurysm formation due to weakening of the venous wall after repeated punctures. Its rupture causes severe bleeding that can lead to death. We report the case of a patient with two AVF saccular aneurysms treated by aneurysmorrhaphy. The technique and the postoperative follow-up are presented in detail. Aneurysmorrhaphy is a good option to repair the AVF wall when the aneurysmal segment is short, thus avoiding the placement of prosthetic grafts and the performance of two anastomoses.
