   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiac surgery; Cardiopulmonary bypass; Consequences; Delirium; Detection; Documentation; Economical aspect; Hospitalisation; Risk factors; Screening scales; Thoracic and Cardivascular Suregery; kirurgi; särskilt thoraxkirurgi; omvårdnadsforskning med medicinsk inriktning; Caring Sciences;

   Sammanfattning : Background: Cardiac surgery is considered safe, but postoperative delirium (POD) remains frequently reported. Delirium is characterised by fluctuations in consciousness and cognition, and can be subdivided into disturbed psychomotoric activity (hyperactive and hypoactive) and psychiatric symptom profiles (psychotic and emotional).

4. 8. The sensational hand. Clinical assessment after nerve repair

   Författare :Birgitta Rosén; Malmö Handkirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; substitution of senses; artificial sensibility; reliability; validity; diagnose-specific; documentation; assessment; longitudinal; functional outcome; hand; sensibility; ulnar nerve; nerve repair; median nerve; brain plasticity; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

   Sammanfattning : Following the transection and repair of major nerve trunks in the forearm, the functional outcome is influenced by mechanisms in the peripheral, as well as in the central nervous system. In the present thesis the interest is focused on assessment of the outcome after nerve repair, central nervous factors influencing the outcome, and sense substitution to compensate for sensory loss.

5. 9. Guidance and Visualization for Brain Tumor Surgery

   Författare :Filipe Miguel Maria Marreiros; Örjan Smedby; Sandro Rossitti; Karin Wårdel; Anders Ynnerman; Ole Jacob Elle; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Image guidance and visualization play an important role in modern surgery to help surgeons perform their surgical procedures. Here, the focus is on neurosurgery applications, in particular brain tumor surgery where a craniotomy (opening of the skull) is performed to access directly the brain region to be treated. LÄS MER

7. 10. On severe traumatic brain injury : aspects of an intra cranial pressure-targeted therapy based on the Lund concept

   Författare :Magnus Olivecrona; Lars-Owe D Koskinen; Bertil Romner; Umeå universitet; []

   Sammanfattning : Severe Traumatic Brain Injury (sTBI) is a major cause of mortality and morbidity. At the Department of Neurosurgery Umeå University Hospital subjects with sTBI are treated with an intracranial pressure (ICP) guided therapy based on physiological principles, aiming to optimise the microcirculation of the brain so avoiding secondary brain injuries.
