Creencias respecto al ejercicio físico y cambios psicológicos tras sufrir un Síndrome Coronario Agudo
2019
Actualmente, siguen existiendo algunos interrogantes acerca del estado psicológico de las personas que han sufrido un Síndrome Coronario Agudo (SCA). El presente trabajo tiene un doble objetivo. En primer lugar, a partir de un estudio piloto compuesto por hombres y mujeres, evaluar los cambios en las creencias respecto a la utilidad del ejercicio como herramienta de salud psicológica y física. En segundo lugar, a partir de un segundo estudio formado por mujeres, comparar los cambios en variables psicológicas y su ajuste a la enfermedad así como observar diferencias, tras su paso por un programa de rehabilitación cardiaca que incluye ejercicio físico. Se evaluaron 37 pacientes de ambos sexos…
Peripheral Intravenous Access in Preterm Neonates during Postnatal Stabilization: Feasibility and Safety
2017
Background Current European Guideline for resuscitation recommends a centrally positioned umbilical venous catheter as the best option for administering necessary drugs. Especially in preterm infants, a frequently used alternative is the peripheral venous catheter. Methods Two randomized controlled studies were conducted at the Division of Neonatology, Medical University of Graz. During neonatal resuscitation, a standardized protocol was filled out by an uninvolved observer including time points after birth of all attempts of venous puncture, time point of successful venous puncture, and total number of needed attempts. Arterial oxygen saturation (SpO2) and heart rate (HR) were measured usi…
[S1 Herpes zoster localization: acute urinary retention in woman].
2011
Acute urinary retention in women is rare. The varicella-zoster virus causes inflammatory lesions of the sensory-root ganglions, meninges and, less frequently, spinal cord. Herpes zoster has been reported to affect, although rarely, lower urinary tract innervations, and acute urinary retention can be thought to occur in the presence of sacral dermatome involvement. Usually it is located in S2–4 dermatome and the prognosis for acute urinary retention is benign resolving in about 20 days. We present a case in which the S1 dermatome was interested and acute urinary retention developed. After 10 days of specific therapy and self catheterism the problem resolved.
Insights on Central and Peripheral Venous Catheterization; Biology, Anatomy, Surgical Aspects and Nursing Management (Our Experience)
2009
After a review of the main anatomical districts of relevance to central and peripheral venous catheterization, we analyze the primary guidelines for the management of cannulation of central and peripheral venous catheters; a background study relative to this subject is then carried out. The aim of the present study is to review the main central and peripheral catheterization methods, and to share our experience with particular emphasis on analyzing common complications
Klinische Erfahrungen mit dem Kensey-Katheter-System - Komplikationen und Ergebnisse
1990
Fifteen procedures have been carried out in 14 patients using the Kensey rotation angioplasty system. Sixteen occlusions of the superficial femoral artery, with an average length of 10.2 cm (3 to 24 cm) and one artery with multiple stenoses were treated. The following results were obtained: creation of a lumen, with subsequent balloon dilatation in eight out of fifteen procedures; in two patients the vessels were occluded shortly after the procedure, due to complications (one obstructive plaque and one haematoma); five perforations, three dissections and one peripheral embolus. The total complication rate was 11 out of 15 cases, clinical improvement was obtained in six out of 15 cases.
The use of an endostapler in the treatment of supralevator abscess of intersphincteric origin.
2014
Aim This technical note describes the use of an endostapler for the definitive treatment of supralevator abscess upward from an intersphincteric origin. Method A two-stage treatment was performed. First an endoanal drainage was performed by inserting a mushroom catheter in the supralevator abscess cavity. In the second stage transanal unroofing of the fistula was performed with an endostapler. Results Since 2011, three patients have been treated in this way. After 2 years of follow up, none of the patients had recurrence of the abscess or been referred for anal incontinence. Conclusion The use of an endostapler in the treatment of supralevator abscess of intersphincteric origin may be an al…
Retrograde recanalization of an in-stent ostial chronically occluded right coronary artery
2010
We describe a case of a chronic proximal in-stent CTO extending up to the ostium of a right coronary artery where successful achievement of guidewire passage through the CTO was performed with a retrograde approach. Guidewire trapping into the right guiding catheter was performed thereafter and procedure was completed by retrograde balloon crossing and antegrade stenting. © 2009 Elsevier Ireland Ltd.
In vitro comparison of platinum-iridium and gold tip electrodes: lesion depth in 4 mm, 8 mm, and irrigated-tip radiofrequency ablation catheters
2009
Aims We compared a newly developed irrigated gold tip electrode ablation catheter and a gold tip 4 and 8 mm catheter with the corresponding platinum–iridium (Pt) tip catheters in an in vitro setting. Methods and results In a flow chamber simulating physiological flow conditions, radiofrequency catheter ablation was performed on tissue samples of porcine endomyocardium and liver. Lesion depth, energy and temperature delivery, and popping frequency were determined. Two hundred and fifty-three ablations were conducted. Four and eight millimetre, gold tip electrode catheters produced significantly deeper lesions compared with the Pt tip electrode (liver 4 mm: 4.67 ± 1.7 vs. 2.9 ± 1.0 mm, P < 0.…
Renal artery denervation for treating resistant hypertension: Definition of the disease, patient selection and description of the procedure
2012
Arterial hypertension is responsible for a significant burden of cardiovascular morbidity and mortality, worldwide. Although several rational and integrated pharmacological strategies are available, the control of high blood pressure still remains largely unsatisfactory. Failure to achieve effective blood pressure control in treated hypertensive patients may have a substantial impact on individual global cardiovascular risk, since it significantly increases the risk of developing hypertension-related macrovascular and microvascular complications. Arterial hypertension is arbitrarily defined as 'resistant' or 'refractory' when the recommended blood pressure goals (clinic blood pressure below…
ESH position paper: renal denervation - an interventional therapy of resistant hypertension
2012
Experts from the European Society of Hypertension prepared this position paper in order to summarize current evidence, unmet needs and practical recommendations on the application of percutaneous transluminal ablation of renal nerves [renal denervation (RDN)] as a novel therapeutic strategy for the treatment of resistant hypertension. The sympathetic nervous activation to the kidney and the sensory afferent signals to the central nervous system represent the targets of RND. Clinical studies have documented that catheter-based RDN decreases both efferent sympathetic and afferent sensory nerve traffic leading to clinically meaningful systolic and diastolic blood pressure (BP) reductions in pa…
