    Sammanfattning : Laparoscopic liver surgery is complicated due to the structure of this organ with open sinusoids. A serious disadvantage is the risk of gas embolism (GE) due to CO2 pneumoperitoneum. CO2 can enter the vascular system through a wounded vein. A common opinion is that gas fluxes along a pressure gradient, e. LÄS MER

  3. 2. Technical Aspects of Laparoscopic Liver Resection. An Experimental Study

    Författare :Kristinn Eiriksson; Dag Arvidsson; Sten Rubertsson; Bjørn Edwin; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gas embolism; laparoscopy; liver resection; pneumoperitoneum; carbon dioxide; argon; bleeding; stapling device;

    Sammanfattning : Various techniques are used to transect the liver. With increase in laparoscopic liver resections (LLR), it is of even more interest to develop surgical techniques to minimize bleeding and the risk for gas embolism during transection. Instrument like argon enhanced coagulator provides good hemostasis but increases the danger of gas embolism. LÄS MER

  4. 3. Carbon dioxide de-airing in cardiac surgery

    Författare :Peter Svenarud; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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

  5. 4. Wound ventilation : A new concept for prevention of complications in cardiac surgery

    Författare :Mikael Persson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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.
