Filter by:The investigators want to test the accuracy of the Smartphone application Darwin Edge rVSM in measuring heart rate, as compared to traditional pulsoxymetry. The intervention is to look at the smartphone camera for approximately 30 seconds, and after that to compare the heart rate value with that obtained with a recording by pulsoxymetry.
This is a single-site, randomized, controlled trial. Investigators will evaluate feasibility of the Emergency Department Healthcare Education Assessment and Response for Teen Relationships (ED-HEART) intervention among adolescents age 14-19 years receiving care in the Children's Mercy emergency department.
TRICS-IV is an international, multi-centre, open-label randomized controlled trial of two commonly used transfusion strategies in moderate to high risk patients who are 65 years of age or younger undergoing cardiac surgery on cardiopulmonary bypass, using a superiority trial design.
Dopamine is frequently used as an inotropic drug to elevate cardiac output. In addition to the beneficial cardiac effect of this drug, the few previous studies addressing its ability to alter the airway tone reported controversial results. Thus, the investigators aimed at clarifying the potential of dopamine to alter gas exchange outcomes and the airway tone in patients undergoing cardiac surgeries with cardiopulmonary bypass. Blood gas parameters, airway resistance, tissue damping and tissue elastance will be measured in the patients before the CPB, immediately after CPB, and 5 min after administration of dopamine (3 mcg/kg/min). The importance of the research is to reveal whether the beneficial mechanical changes after dopamine administrations are associated with improvements in gas exchange outcomes. Clarification of this research question have scientific relevance and may also improves patient outcomes.
As the critical care practice has improved over the last decades more patients are recovering from intensive care therapy. However, muscle atrophy and neuromuscular dysfunction are commonly observed sequelae after critical illness and are thought to play important roles in the development of intensive care unit acquired weakness (ICUAW). As a consequence, these entities may contribute to the impaired physical function and prolonged convalescence reported by ICU patients up to twelve months after discharge. Thus, strategies to counteract muscle atrophy and neuromuscular dysfunction acquired during the ICU stay may therefore potentially improve physical outcome and reduce the overall burden of critical illness. Limited information is available on muscle function in ICU patients and to our knowledge no muscle stimulation methods are currently available for evaluating muscle fatigue in large, proximal muscles groups, such as m. quadriceps, in non-cooperating ICU patients.
