2. 21. Microdialysis and Intensive Care. Clinical and experimental studies

   Author : Per Ederoth; Anestesiologi och intensivvård; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology; traumatic brain injury; glucose; glycerol; lipolysis; epidural; postoperative analgesia; experimental pancreatitis; human; blood-brain barrier; morphine; pharmacokinetics; Microdialysis; intensive care; Anestesiologi; intensivvård;

   Abstract : Microdialysis was used to monitor local concentrations of energy metabolites in different organs, and to study the pharmacokinetics of morphine over the blood-brain barrier in intact and injured brain tissue in conditions treated in the Intensive Care Unit. After major abdominal or thoracoabdominal surgery, postoperative thoracic epidural analgesia resulted in higher glycerol concentrations in the deltoid subcutaneous adipose tissue, implying increased lipolysis, on the third postoperative day as compared to intravenous infusion of morphine, possibly due to a locally increased sympathetic tone.

4. 22. Transvascular fluid exchange with application to the brain. An experimental study in cat skeletal muscle and brain

   Author : Lis Kongstad; Anestesiologi och intensivvård; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurologi; neurophysiology; neuropsychology; Neurology; intensivvård; capillary filtration coefficient; Capillary permeability; reflection coefficient; brain edema; dural puncture; Anaesthesiology; Anestesiologi; intensive care; neuropsykologi; neurofysiologi;

   Abstract : This study evaluated transcapillary fluid exchange in the cat brain and in a cat skeletal muscle enclosed in a plethysmograph. A method for determination of capillary permeability (capillary filtration coefficient and reflection coefficient) and effects of transcapillary hydrostatic pressure changes were studied We found that capillary fluid permeability in a tissue can be determined by the capillary filtration coefficient, even when arterial pressure and vascular tone are changed.

5. 23. Modern inhalation agents and effects of anaesthesia equipment during low-flow anaesthesia

   Author : Anders Johansson; Anestesiologi och intensivvård; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anestesiologi; intensive care; intensivvård; Anaesthesiology; humidity and temperature; heat and moisture exchanger; isoflurane; desflurane; sevoflurane; anaesthetics volatile; carbon dioxide absorber; Low-flow; re-breathing circle circuit;

   Abstract : Volatile agents are economically and ecologically acceptable only when administered via low-flow systems. However, sevoflurane degrades during low-flow anaesthesia to compound A, and a high carbon dioxide absorber temperature increases this degradation. READ MORE

6. 24. Cooling and dopamine

   Author : Roger Roscher; Anestesiologi och intensivvård; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology; electrophysiology; cooling; Hypothermia; swine; lung transplantation; organ preservation; dopamine; circulation; contractility; oxygenation; intensive care; Anestesiologi; intensivvård;

   Abstract : There is little knowledge about the circulatory effects of dopamine in hypothermia. Induced hypothermia has been shown to improve outcome in various settings. Hypothermia is also used for preservation of organs that are harvested for transplantation. READ MORE

7. 25. Anaesthetics and the blood vessel wall. Actions of propofol and sevoflurane on sympathetic and endothelial control of smooth muscle function

   Author : Karin Thorlacius; Anestesiologi och intensivvård; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology; intensive care; Anestesiologi; intensivvård; vein.; artery; endothelium; sympathetic nervous system; inhalation agent sevoflurane; Anaesthesia; intravenous propofol;

   Abstract : The anaesthetics we use today dose-dependently decrease the mean arterial pressure partly due to direct or indirect effects on the blood vessels. In the present thesis human omental arteries and veins and rat femoral arteries were investigated in vitro concerning the effects of the intravenous anaesthetic propofol and the volatile anaesthetic sevoflurane on the function of the perivascular sympathetic nerves and the endothelial cells.
