  1. 6. Wound ventilation : a new concept for prevention of complications in cardiac surgery

    Författare :Mikael Persson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Cardiac surgery; air embolism; airborne contamination; wound infection; desiccation; adhesion; carbon dioxide insufflation; antiseptic agent; ethanol; humidification;

    Sammanfattning : Cardiac surgery through an open chest wound is a major operation both in size and duration. The wound exposure to ambient air implies considerable risks. 1) Air may enter the heart and great vessels and embolize to the brain or cardiac muscle where it may cause dysfunction or permanent damage.

    Sammanfattning : Objective: Pulmonary oedema is life threatening. A method is needed for reliable measurement of lung water in man in order to clarify aetiology, pathophysiology, prognosis, and to evaluate treatments against pulmonary oedema. LÄS MER

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

    Sammanfattning : 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).
