2. 1. 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

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. Nitric oxide in experimental pulmonary embolism

   Author : Kristofer F Nilsson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Nitric oxide (NO) is an important modulator of the pulmonary circulation both at basal state and in pulmonary hypertension. Low levels of NO are detectable in exhaled gas which is believed to mirror pulmonary NO formation and elimination. READ MORE

6. 4. Diving and the brain

   Author : Anders Rosén; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biomarkers; brain; central nervous system; decompression sickness; dive research; diving; neuronal damage; saturation diving; tau protein; venous gas embolism; neurofilament light; glial fibrillary acid protein; tau; VGE;

   Abstract : Abstract Introduction There are reports that long-term diving is associated with cognitive impairments. This raises the question if diving itself is harmful to the brain in the absence of decompression sickness or hypoxia. READ MORE

7. 5. Carbon dioxide de-airing in cardiac surgery

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

   Abstract : 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. READ MORE
