1. 1. Cerebral Venous Thrombosis - Complications and Outcomes

   Författare :Erik Lindgren; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cerebral venous thrombosis; complications; outcome; seizures; return to work; dural arteriovenous fistula; follow-up;

   Sammanfattning : Cerebral venous thrombosis (CVT) is a relatively rare cause of stroke, which predominantly affects working-aged adults and particularly women. The clinical course is highly miscellaneous. Data from large cohorts are scarce and knowledge on CVT complications and outcomes are limited. LÄS MER

3. 2. Mean systemic filling pressure - from Guyton to the ICU, and back again

   Författare :Per Werner Möller; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mean systemic filling pressure; venous return; right atrial pressure; positive pressure ventilation; extracorporeal membrane oxygenation;

   Sammanfattning : Introduction: Mean systemic filling pressure (MSFP) is the equilibrated vascular pressure at zero flow. Venous return (VR) driving pressure (VRdP) is the difference between MSFP and right atrial pressure (RAP). LÄS MER

4. 3. Assessment and management of bariatric surgery patients

   Författare :Tomi Pösö; Doris Kesek; Ola Winsö; Roman Aroch; Mats Enlund; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bariatric surgery; morbid obesity; anesthesia; echocardiography; fluid therapy; preoperative; perioperative; venous return; rehydration; volatile rapid sequence induction; spontaneous breathing; sevoflurane.; anestesiologi; Anaesthesiology;

   Sammanfattning : Background: In morbidly obese individuals (MO) cardiorespiratory comorbidities and body habitus challenge the perioperative management of anesthesia. To implement safe and reproducible routines for anesthesia and fluid therapy is the cornerstone in order to minimize anesthesia-related complications and to meet individual variability in rehydration needs.

5. 4. 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.

7. 5. 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
