1. 1. Carbon dioxide de-airing in cardiac surgery

   Författare :Peter Svenarud; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Carbon dioxide; De-airing; Air embolism; Cardiac surgery; Insufflation device; Microemboli; Transesophageal echocardiography;

   Sammanfattning : Background: The risks connected with the presence of air microemboli in open-heart surgery, have recently been emphasized by reports that their number is correlated with the degree of postoperative neuropsychological disorder. Insufflation of carbon dioxide (C02) into the chest wound is used in open-heart surgery to de-air the heart and great vessels. LÄS MER

3. 2. Peritoneal fibrinolysis during pneumoperitoneum and laparoscopic surgery

   Författare :Maria Bergström; Göteborgs universitet; []
   Nyckelord :Laparoscopy; Fibrinolysis; Peritoneum; Mesothelial cells; Carbon Dioxide; Helium;

   Sammanfattning : BACKGROUND Laparoscopic surgery is believed to induce less postoperative adhesion formation compared with open procedures, but information regarding biological impact of a laparoscopic approach is limited. MATERIAL & METHODS Peritoneal response to laparoscopic surgery was assessed in human peritoneal tissue in two clinical trials (paper I & V). LÄS MER

4. 3. Evaluation of carbon dioxide insufflation into the open surgical wound : influence on wound temperature, core temperature, and postoperative outcome

   Författare :Joana Frey; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Introduction: When the internal organ tissues are abruptly exposed to the relative cold and dry ambient air during open surgery, body heat is lost through radiation, evaporation, and convection. Also general and neuraxial anesthesia contributes to a decrease in core temperature, mainly due to a shift of the threshold for thermoregulatory defense mechanism toward lower temperatures. LÄS MER

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

   Författare :Jesper Nyman; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   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).

7. 5. 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.
