2. 1. Carbon Dioxide Pneumoperitoneum - Hemodynamic Consequences and Thromboembolic Complications

   Author : Fredrik Lindberg; K G Ljungström; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Laparoscopic surgery; carbon dioxide pneumoperitoneum; hemodynamics; coagulation; fibrinolysis; thromboembolic complications; phlebography; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

   Abstract : The laparoscopic way of performing general surgical procedures was introduced all over the Western world in a few years around 1990. No previous scientific studies of the safety of this new way of performing general surgery had been undertaken. READ MORE

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

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

   Abstract : 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. READ MORE

5. 3. Peritoneal fibrinolysis during pneumoperitoneum and laparoscopic surgery

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

   Abstract : 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). READ MORE

6. 4. Gas Embolism in Laparoscopic Liver Surgery

   Author : Diddi Fors; Sten Rubertsson; Dag Arvidsson; Tor Inge Tønnessen; Uppsala universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE

7. 5. The Effect of CO2-Pneumoperitoneum on Ventilation Perfusion Distribution of the Lung

   Keywords : lung; atelectasis; computed tomography; multiple inert gas elimination technique; model; pig; Pa–ECO2 ratio; surgery; laparoscopy; lung; blood flow; single photon emission computed tomography; ventilation perfusion distribution; gas exchange; hypoxic pulmonary vasoconstriction; MEDICINE; MEDICIN;

   Abstract : Laparoscopic operations are a common and popular way for abdominal procedures. They are usually performed by insufflation of carbon dioxide (CO2) into the abdominal cavity. However, insufflation of CO2 may interfere with cardiac and circulatory as well as respiratory functions. The CO2-pneumoperitoneum (PP) may cause hypercarbia and acidosis. READ MORE
