    Abstract : Abstract Introduction There are reports that long-term diving is associated with cognitive impairments. This raises the question if diving itself is harmful to the brain in the absence of decompression sickness or hypoxia. READ MORE

  4. 2. Measures to prevent microembolization in cardiac surgery and during angiography with special reference to carbon dioxide

    Author : Jesper Nyman; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: Cardiovascular interventions including open heart surgery using cardiopulmonary bypass (CPB) and coronary angiography may introduce air and particulate arterial embolism that may lead to tissue lesions of the brain and other organs. Aims: To assess: if CO2-insufflation of an empty CPB circuit decreases number of gaseous emboli in the prime compared with a conventional CPB circuit, which holds air before fluid priming (Study I); the efficacy of a new mini-diffuser device for CO2 de-airing in a minimally invasive open cardiothoracic wound cavity model and in patients undergoing minimally invasive open aortic valve surgery (Study II); if an extra separate venous reservoir abolishes CO2-insufflation induced hypercapnia and retains sweep gas flow of the oxygenator constant during open heart surgery (Study III); if there is a difference in the incidence of cerebral microemboli when using either the femoral or the radial approach during coronary angiography (Study IV).
