Worldwide Experiences with Assisted Peritoneal Dialysis.

End-stage renal disease (ESRD) is common in the elderly population, and renal replacement therapy (RRT) is often required. However, in this particular subgroup of patients, the choice between hemodialysis (HD) and peritoneal dialysis (PD) is often not an easy decision to make. Published literature has adequately demonstrated that PD prevalence is significantly less than HD across all patient age groups despite several advantages. We also know that elderly patients are less likely to complete a PD assessment, due to both medical and social barriers. Additionally, elderly patients are often reluctant to go ahead with PD despite being eligible PD candidates, mainly due to the fear of performing self-therapy. Recently, many new assisted PD (asPD) programs have cropped up in several countries. The main aim of these programs is to overcome barriers to PD and to promote PD utilization among elderly and non-self-sufficient patients. Although asPD has proven to be associated with good clinical results, there still remain concerns about its greater use. In this review, we will first describe an ideal asPD model and then enumerate examples of strategies and outcomes associated with successful asPD programs worldwide.

Assessment of long-term vasoplegia induced by brachial plexus block: a favorable effect for hemodialysis angioaccess surgery?

PURPOSE: Loco-regional anesthesia, along with the neurosensitive inhibition causes arterial and venous vasodilatation, that could be of interest for vascular access surgery. We evaluated the long term vasoplegia persistence after brachial plexic block. METHODS: Five patients submitted to brachial plexus block for an orthopedic procedure have been observed. Both radial arteries, that of the blocked arm and the opposite as a control, were analyzed by ultrasound examination, at time 0 and 360 minutes after anesthesia induction. All patients were treated with the same anesthesiologic protocol: axillary approach, use of an electroneurostimulator, injection 10 ml of ropivacain 7.5% + 10 ml of mepivacain 2%. The parameters evaluated from the arterial ultrasound flowmetry were: peak systolic velocity (PSV), end diastolic velocity (EDV) and resistance index (RI). RESULTS: No modification of the arterial flow were observed in the control arm at 0 and 360'after block induction. The blocked arm instead showed a significant decrease of the resistive index, stable at 360 minutes. CONCLUSIONS: The vasoplegia accompaning plexic block lasted 6 hours after anesthesia induction. Whereas this longstanding haemodynamic effect is beneficial for early patency of vascular access for hemodialysis, needs to be ascertained by further investigations.

Heart failure: tools for nursing and medical treatment.

BACKGROUND: To validate a structured interview designed to evaluate the healthcare and information needs of patients with heart failure (HF), who were also characterized by means of the Kansas City Cardiomyopathy Questionnaire (KCCQ) and the 36-item Short-Form Health Survey (SF-36). METHODS: Forty-five in- and outpatients with HF were administered a structured interview concerning their information and healthcare needs (together with the KCCQ and SF-36) with the aim of investigating the effects of healthcare models on their quality of life (QoL). Twenty-one patients were also involved in a one-week test-retest validity study carried out in order to verify reproducibility and stability by means of concordance and K statistics. RESULTS: The reproducibility of the structured interview was good or very good for all items, with a mean Kw of 0.59; the clarity and acceptability of most of the questions were good. Positive judgements of hospital care inversely related to the patients' New York Heart Association class. The subjects about which the patients sought greater information were diet, sleep, therapies and physical exercise, with cardiologists and general practitioners (GPs) being more involved than nurses. The most frequently discussed subject was diagnostic examinations. The questionnaire scores of our patients were generally lower than those reported in the literature, possibly because of their advanced age. However, it is difficult to believe that the quality of care was extraneous to their generally worse health-related QoL. CONCLUSIONS: Our HF patients experienced a 'basic' healthcare model (hospitals, GPs, cardiologists) and judged them acceptable. Their ability to think critically about care was increasingly compromised as HF progressed and their health-related QoL decreased.
