1. 1. Reducing Atelectasis during General Anaesthesia – the Importance of Oxygen Concentration, End-Expiratory Pressure and Patient Factors : A Clinical Study Exploring the Prevention of Atelectasis in Adults

   Författare :Lennart Edmark; Mats Enlund; Göran Hedenstierna; Sten Lindahl; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesia; general. Lung: Atelectasis; CPAP; Oxygen; PEEP; Ventilation; mechanical; Tomography; X-ray computed.; Anestesiologi; Anaesthesiology; Fysiologi; Physiology;

   Sammanfattning : Background: The use of pure oxygen during preoxygenation and induction of general anaesthesia is a major cause of atelectasis. The interaction between reduced lung volume, resulting in airway closure, and varying inspiratory fractions of oxygen (FIO2) in determining the risk of developing atelectasis is still obscure.

3. 2. Urea and Non-Protein Nitrogen Metabolism in Infants : With Special Reference to the Sudden Infant Death Syndrome (SIDS)

   Författare :Mary George; Sten Lindahl; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Urea; non-protein nitrogen metabolism; SIDS; drinking water nitrate concentration; carbon dioxide production; Kirurgi; Surgery; Kirurgi; anestesiologi; Anaesthesiology;

   Sammanfattning : A large amount of non-protein nitrogen, in the form of urea and ammonium, is present in human breastmilk; however its physiological role in the infant is as yet not fully understood. It has been hypothesized that an insufficient enteric metabolism of urea could play a role in the sudden infant death syndrome (SIDS). LÄS MER

4. 3. Mechanical chest compressions and gender differences in out-of-hospital-cardiac-arrest

   Författare :Erik Lindgren; Sten Rubertsson; Bertil Lindahl; Uppsala universitet; []
   Nyckelord :Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

   Sammanfattning : Paper I and II. Both early defibrillation and high quality chest compressions are affecting the chances of survival after cardiac arrest (CA). Manual chest compressions delivers only approximately 30% of normal cardiac output and is further deteriorating during transport. LÄS MER

5. 4. Hyperglycemia in Experimental Cerebral Ischemia

   Författare :Maria Molnar; Fredrik Lennmyr; Sten Lindahl; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; brain ischemia; cardiac arrest; cytokines; gene expression; glucose; hyperglycemia; microarray; oxidative stress; pigs; rats; reperfusion; resuscitation S100β; Anaesthesiology and Intensive Care; Anestesiologi och intensivvård; Neuroscience; Neurovetenskap;

   Sammanfattning : Cerebral ischemia is a life-threatening condition associated with a substantial morbidity and mortality. Hyperglycemia, a common coexisting phenomenon in both stroke and cardiac arrest (CA), may further aggravate ischemic brain injury. To date, the therapeutic possibilities are lim-ited and the search for new treatment modalities is warranted. LÄS MER

7. 5. Experimental septic shock – Effects of endotoxemia with special reference to pathophysiological responses in the pig

   Författare :Ewa Söderberg; Miklós Lipcsey; Mats B Eriksson; Anders Larsson; Jan Sjölin; Sten Lindahl; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endotoxin; inflammatory response; animal model; timing; steroid treatment; NGAL; Calprotectin; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

   Sammanfattning : Sepsis and septic shock are conditions, with severe outcome or in many cases death. Sepsis is a systemic inflammatory response trigger by bacteraemia but systemic inflammatory response can also be triggered by major trauma, major surgery, pancreatitis, severe burns etc. LÄS MER
