1. 16. Severe Hemodilution - Clinical and Experimental Studies

   Författare :Valéria Perez de Sá; Anestesiologi och intensivvård; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; shivering; critical oxygen delivery; oxygen consumption; child; dextran; hypothermia; hemodilution; anemia; Anaesthesiology; intensive care; Anestesiologi; intensivvård; lactates;

   Sammanfattning : In children, it is often desirable to minimize allogenic blood transfusion, and this thesis explores the physiology of an alternative method of managing perioperative blood loss: hemodilution with Ringer´s dextran. Methods Clinical studies: Arterial pressure, superior caval venous oxygen saturation (ScvO2) and blood lactate concentration (L) were studied during bone marrow harvesting (BMH) on 23 occasions in 19 children, 1-17 years of age, with healthy hearts and lungs.

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

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

   Sammanfattning : 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.

4. 18. Inhaled Nitric Oxide Therapy : Non-response and Rebound Response

   Författare :Luni Chen; Eddie Weitzberg; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology and intensive care; nitric oxide inhalation; rebound response; non-response; endothelin-1; COX inhibitor; prostaglandin; ARDS; endotoxin; oleic acid; Anestesiologi och intensivvård; Anaesthetics and intensive care; Anestesiologi och intensivvård; Clinical Physiology; klinisk fysiologi;

   Sammanfattning : Therapeutic inhaled nitric oxide (INO) has proved beneficial in patients with pulmonary hypertension. However, around 30-40% of the patients are non-responders to this therapy, and a life-threatening rebound response may occur during attempts to withdraw INO. LÄS MER

5. 19. Transesophageal Echocardiography in Patients Undergoing Elective Coronary Artery Bypass Surgery

   Författare :Ingrid Palmgren; Russell Anderson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology and intensive care; transesophageal echocardiography; low-dose dobutamine; viability; coronary artery bypass; Anestesiologi och intensivvård; Anaesthetics and intensive care; Anestesiologi och intensivvård; anestesiologi; Anaesthesiology;

   Sammanfattning : Transesophageal echocardiography (TEE) has become a useful tool in monitoring the heart in patients during open-heart surgery. This study was undertaken to evaluate whether it is feasible to use TEE to assess left ventricular myocardial viability in anesthetized patients scheduled for coronary artery bypass grafting (CABG).

7. 20. Pain following Surgery: Management, Outcome, and Prediction

   Författare :Åsa Rudin; Anestesiologi och intensivvård; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intensivvård; Epidural analgesia; Outcome; Prediction.; Anaesthesiology; intensive care; Anestesiologi; Postoperative pain; Patient controlled analgesia;

   Sammanfattning : Despite advances in the treatment of postoperative pain, nearly 30% of patients experience moderate to severe pain following major surgery. The present thesis includes four studies intended to evaluate important aspects of postoperative pain. LÄS MER
