  1. 1. Gas Embolism in Laparoscopic Liver Surgery

    Författare :Diddi Fors; Sten Rubertsson; Dag Arvidsson; Tor Inge Tønnessen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gas embolism; laparoscopic liver; CVP; PEEP; high frequency jet ventilation; cardiopulmonary physiology; carbon dioxide; Anaesthesiology and Intensive Care; Anestesiologi och intensivvård;

    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

    Sammanfattning : The way the fuel is introduced into the combustion chamber is one of the most important parameters for the power output and the generation of emissions in the combustion of liquid fuels. The interaction beween the turbulent gas flow field and the liquid fuel droplets, the vaporisation of them and the mixing of the gaseous fuel with the ambient air that are vital parameters in the combustion process.

  4. 3. Clinical aspects on central venous cannulation

    Författare :Andreas Pikwer; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Central venous catheters are mainly being used for reliable infusion of fluids and potentially irritant drugs, for haemodialysis, and for assessment of right atrial or central venous pressure (RAP/CVP). Current guidelines state that central venous catheterization should be followed-up by immediate anterior-posterior chest X-ray to confirm appropriate positioning and to detect iatrogenic pneumothorax.

  5. 4. Haemodynamic management in liver surgery

    Författare :Lena Sand; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; liver resection; nitroglycerine; central venous pressure; vasopressin; patient position; PEEP;

    Sammanfattning : Background: Liver resection surgery is a potentially curative treatment for liver tumours. The liver is a highly vascular organ, and substantial intra-operative blood loss is common. Increased blood loss negatively impacts both postoperative outcome and long-term survival. LÄS MER

  7. 5. Cerebral Perfusion during Cardiopulmonary Bypass

    Författare :Thomas Tovedal; Fredrik Lennmyr; Stefan Thelin; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Impaired superior vena cava (SVC) cannula outflow during cardiopulmonary bypass (CPB) is a frequent issue, often manifested by only marginal changes in routine monitoring parameters. Nevertheless, significant impact on cerebral perfusion may result. LÄS MER
