Adjustable tourniquet to manipulate pulmonary blood flow after Norwood operations

2000

Abstract Background . Survival after first-stage palliative Norwood operations for single ventricle with systemic outflow obstruction is mainly dependent on a balanced ratio of pulmonary blood flow to systemic blood flow. Here we report the clinical results using a modified technique that allows a controlled systemic-to-pulmonary shunt flow to prevent pulmonary overcirculation. Methods . From 1995 to 1998, of 26 infants undergoing first-stage palliative Norwood operations, 7 had placement of an adjustable tourniquet around a modified right Blalock-Taussig shunt. Results . Hospital survival was 20 of 26 patients (77%). All 7 patients in whom snaring of the shunt was indicated survived. Two p…

Effects of cardiopulmonary rehabilitation on the muscle function of children with Congenital Heart Disease : a prospective cohort study

2021

Critical medical and surgical advances have led to a shift in the care and management of children with congenital heart disease (CHD). These patients present with muscle deconditioning, which negatively influences their response to exercise, functional capacities, and quality of life. This study evaluates the influence of a cardiopulmonary rehabilitation program (CPRP) on the function of peripheral musculature of children with CHD. A single-center prospective cohort study was designed. Fifteen CHD subjects, between 12 and 16 years of age, with reduced aerobic capacity on a cardiopulmonary exercise test, were included in a three-month, 24-session CPRP. Measurements of the subjects’ handgrip …

What Is the Role of Minimally Invasive Mitral Valve Surgery in High-Risk Patients? A Meta-Analysis of Observational Studies

2016

Background. Minimally invasive valve surgery is related to certain better postoperative outcomes. We aimed to assess the role of minimally invasive mitral valve surgery in high-risk patients. Methods. A systematic literature review identified eight studies of which seven fulfilled criteria for metaanalysis. Outcomes for a total of 1,254 patients (731 were conventional standard sternotomy and 523 were minimally invasive mitral valve surgery) were submitted to meta-analysis using random effects modeling. Heterogeneity and subgroup analysis with quality scoring were assessed. The primary end point was early mortality. Secondary end points were intraoperative and postoperative outcomes and long…

Experimental Hyperthermia during Cardiac Arrest and CPR Is Associated with Severe Spontaneous Hypothermia in Mice

2012

Background: Since genetically engineered mice are becoming more and more available, these animals become of high interest to study physiologic and pathophysiologic pathways of brain ischemia. The aim of this study was to examine body temperature (Tb), physical activity variation and neurohistopathology in mice exposed to normothermic and hyperthermic cardiac arrest and cardiopulmonary resuscitation (CA/CPR). Methods: Male C57Bl/6 mice weighing 22 - 27 g were implanted intraperitoneally with a radio telemeter and subjected to 10 min cardiac arrest followed by cardiopulmonary resuscitation. Normothermia (37.5°C) or hyperthermia (39.0°C) was induced by controlling pericranial temperature durin…

Simulación clínica en pediatría y neonatología: adaptación telemática del proyecto de innovación educativa

2021

[EN] Introduction: Framed within an educational innovation project in the nursing degree, we introduce the application of realistic scenarios, generated through the EDISON tool to deal with topics such as pediatric and neonatal CPR. Due to the COVID-19 pandemic, an adaptation of the project to the telematic modality was proposed. Methodology: Analytical exploratory study where the effectiveness of a training intervention in a confinement context was evaluated. It was based on the use of audiovisual materials created through EDISON that configured a VideoBook that was made available to students through the Virtual Platform, evaluating its effectiveness through the final exam of the subject. …

Prospective comparison of cardiopulmonary events during minilaparoscopy and colonoscopy under conscious sedation.

2005

BACKGROUND AND STUDY AIMS Cardiorespiratory parameters were examined throughout diagnostic minilaparoscopy procedures. The same parameters were analyzed during colonoscopy, and the data were compared. PATIENTS AND METHODS Sixty-five consecutive unselected patients undergoing minilaparoscopy (group 1: ASA I, n = 34; group 2: ASA II/III, n = 31) and 61 consecutive unselected patients undergoing colonoscopy (group 3: ASA I, n = 31; group 4: ASA II/III, n = 30) were included. Oxygen saturation (Sao (2)), heart rate (HR) and mean arterial pressure (RRm) were measured continuously, and 12-lead electrocardiography (ECG) recordings were made at specific times during each procedure. RESULTS Minor di…

Ekspiratorisk flow avgrensingar under fysisk belastning hos ungdommar med astma : Før og etter 10 vekers intervensjon

2019

Masteroppgave folkehelsevitenskap ME516 - Universitetet i Agder 2019 Background:Asthma is a chronic inflammatory disorder associated with variable airflo w obstruction and bronchial hyperresponsivness. Asthma may interfere with the ability of childre n and adolescents to participatein physical activity, as well ascreatebarriers towards involvement. Physical activity is an important stimulus for asthma symptoms. Exercise-induced bronchoconstriction is traditionally used when physical activity is the cause of asthma symptoms, but this is measured after exercise. There is little knowledge about flow limitat io n during exercise. Aim:The purpose of this study is to investigate expiratory flow l…

Transpulmonary cardiac output measurement in a rat model of cardiac arrest and CPR: Impact of vascular access

2009

Objective: The present study investigated the impact of the vascular access site for cardiac output (CO) measurement by thermodilution on survival and neurohistopathological injury in a rat model of cardiac arrest (CA) and cardiopulmonary resuscitation (CPR). Secondary the influence of the vascular access site on cardiac output measurements was examined. Methods: Rats underwent asphyxial CA and CPR. Thermocouple probes were either placed via the femoral artery into the bifurcation of abdominal aorta/iliac artery (Femoral) or via the carotid artery into the aortic arch (Carotid). CPR was initiated after 9 min CA. Local cerebral blood flow (lCBF) and CO were assessed for 120 min after restora…

A New Off-Pump Hybrid Open and Endovascular Repair to Treat Ductus Botalli and Ascendens Aneurysms

2012

To report a combined ascending aorta and aortic arch hybrid repair, we performed off-pump with no aortic graft replacement. A 65-year-old man, developing progressive recurrent laryngeal nerve paralysis, underwent a computed tomography (CT) angiography detecting nonpatent residual ductus Botalli aneurysm and ascending aorta aneurysm. Due to severe multimorbidities, a less-invasive alternative was elaborated. In a first step, appropriate proximal landing zone for aortic stent grafting was achieved by ascending aorta diameter reduction, with epiaortic wrapping, and debranching the supra-aortic trunks. In the second step, endovascular stent grafts were deployed from proximal ascending aorta to…
