1. 1. Fluid dynamic principles for analysis of intracranial pressure control : application towards space medicine and hydrocephalus

   Författare :Petter Holmlund; Anders Eklund; Sara Qvarlander; Jan Malm; Marek Czosnyka; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intracranial pressure; posture; cerebrospinal fluid; microgravity; venous collapse; internal jugular vein; fluid dynamics; venous pressure; spaceflight-associated neuro-ocular syndrome; hydrocephalus; mathematical modeling; ultrasound; magnetic resonance imaging;

   Sammanfattning : Intracranial pressure (ICP) is an important component of the fluid dynamic environment of the brain and plays a central role with regards to the maintenance of normal cerebral blood flow and neuronal function. However, many regulatory mechanisms controlling the ICP are still poorly understood. LÄS MER

3. 2. Clinical aspects on central venous cannulation

   Författare :Andreas Pikwer; Anestesiologi och intensivvård; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Central venous catheters are mainly being used for reliable infusion of fluids and potentially irritant drugs, for haemodialysis, and for assessment of right atrial or central venous pressure (RAP/CVP). Current guidelines state that central venous catheterization should be followed-up by immediate anterior-posterior chest X-ray to confirm appropriate positioning and to detect iatrogenic pneumothorax.

4. 3. The venous circulation in teleost fish -responses to exercise, temperature and hypoxia

   Författare :Erik Sandblom; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; blood volume; catecholamines; central venous pressure; exercise; hypoxia; mean circulatory filling pressure; preload; renin-angiotensin; temperature; vascular capacitance.;

   Sammanfattning : Sandblom, Erik (2007). The venous circulation in teleost fish -Responses to exercise, temperature and hypoxia. Department of Zoology/Zoophysiology, Göteborg University, Box 463, SE-405 30 Göteborg, Sweden. In fish and other vertebrates, venous capacitance changes have important implications on venous return and cardiac filling pressure. LÄS MER

5. 4. Haemodynamic management in liver surgery

   Författare :Lena Sand; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; liver resection; nitroglycerine; central venous pressure; vasopressin; patient position; PEEP;

   Sammanfattning : Background: Liver resection surgery is a potentially curative treatment for liver tumours. The liver is a highly vascular organ, and substantial intra-operative blood loss is common. Increased blood loss negatively impacts both postoperative outcome and long-term survival. LÄS MER

7. 5. Cardiovascular regulation in women with vasovagal syncope : With special reference to the venous system

   Författare :Johan Skoog; Toste Länne; Marcus Lindenberger; Helene Zachrisson; Ola Eiken; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Although vasovagal syncope (VVS) is a common clinical condition the mechanisms behind VVS remain elusive. Upright posture is the major trigger of VVS and lower limb blood pooling affecting cardiac output has been proposed as a major determinant. The overall aim of this thesis was twofold. LÄS MER
