   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adrenaline; blood flow; blood redistribution; ischemia; muscle injury; skeletal muscle; strain-gauge plethysmography; sympathetic tone; transmural pressure; 99mTechnetium clearance; tennis elbow; venous compliance; venous occlusion plethysmography; 133Xenon clearance; adrenaline;

   Abstract : A variety of vasoregulatory systems are involved in the complex control of blood flow inhuman skeletal muscle. The interaction between these systems where one system canoverride or modify the other makes blood flow regulation complicated. READ MORE

4. 2. Lower limb venous incompetence and the effect of radiofrequency ablation versus open surgery : Focus on haemodynamics, quality of life and health economic aspects

   Author : Oskar Nelzén; Helene Zachrisson; Toste Länne; Johan Skoog; Gunnar Plate; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chronic venous incompetence; Varicose veins; Radiofrequency ablation; High ligation stripping Duplex ultrasound; Strain-gauge plethysmography; Quality of Life; Health economic evaluation;

   Abstract : Chronic venous incompetence (CVI) is a common condition, and varicose vein treatment is one of the most-common surgical procedures performed worldwide. Common symptoms of CVI are pain, cramps, itching, feeling of leg heaviness and venous claudication. Advanced CVI can lead to skin changes, eczema and venous ulcers. READ MORE

5. 3. Studies on venous function after deep venous thrombosis

   Author : Lena M Persson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : venous plethysmography;

   Abstract : Background: The incidence of deep venous thrombosis (DVT) is estimated to be about 1-2/1000 per year of which approximately 4 % are located in the arm veins. Some of the most important late effects of a DVT are chronic venous dysfunction and the development of post-thrombotic syndrome (PTS). READ MORE

6. 4. Fiber-optic sensors for blood flow and respiration rate measurements

   Author : Erik Stenow; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : Optical fibers and fiber-optic sensors have in the last century been subjects for a great interest especially in industry and communication but also in medicine. Optical fibers are used in endoscopes and as light guides for laser surgery. READ MORE

7. 5. Haemodynamic and ventilatory effects of laparoscopic surgery

   Author : Lena Andersson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Laparoscopy; C02 pneumoperitoneum; indicator- dilution technique; central haemodynamics; cardiac output; central blood volume; venous occlusion plethysmography; catecholamines; multiple inert gas technique; shunt; abdominal wall lift; intrathoracic pressure; ventilation-perfusion matching; atelectasis; spiral computed tomography.;

   Abstract : Background: It has been shown repeatedly that the establishment of pneumoperitoneum (PP) is associated with increased cardiac filling pressures, as well as increased blood pressure and systemic vascular resistance. Patients without heart or lung disease can compensate for these effects of PP, but cardiopulmonary compromised patients may develop cardiac failure during PP. READ MORE
