  2. 1. Hemodilution with dextran: Effects on blood flow and thrombus formation. An experimental study in the rabbit

    Author : Lieselotte Frost-Arner; Malmö Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatology; orthopaedics; Surgery; Hypertonic saline-dextran; Desmopressin; Heparin; Dextran; Rabbit; Synthetic vascular grafts; Blood flow; Hemodilution; Thrombus formation; Kirurgi; ortopedi; traumatologi; Cardiovascular system; Kardiovaskulära systemet;

    Abstract : Microvascular surgery enables free tissue flaps to cover tissue defects, e.g. after trauma and malignancies. Although major improvements in techniques have been made, problems with poor tissue circulation and thrombus formation still exist. READ MORE

  4. 2. Towards Defence In Depth In Diabetes Glucose Self-Management

    Author : Fredrik Ståhl; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diabetes; model; insulin action; postprandial glucose;

    Abstract : Diabetes is a disease characterized by insufficient capacity to regulate the blood glucose level. In insulin-dependent diabetes, multiple daily injections of insulin have to be administered. In-between scheduled visits to the care provider, the patient has to manage the glucose control independently. READ MORE

  5. 3. Nuclear magnetic resonance and microcirculation: The influence of pulsatile brain-tissue motion on measurements of intravoxel incoherent motion and assessment of haemodynamics using exo- and endogenous tracers

    Author : Ronnie Wirestam; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diagnostic radiology; cortical activation; diffusion; tumor; tumour; ischemic stroke; ischaemic stroke; tracer kinetics; bolus tracking; phase mapping; brain motion; intracranial dynamics; blood flow; haemodynamics; vascularity; MRS; perfusion; MRI; magnetic resonance; Clinical physics; radiology; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Abstract : In this project, the potential of magnetic resonance (MR) imaging and spectroscopy in studies of microcirculation and haemodynamics was evaluated. The spatial and temporal characteristics of human pulsatile brain-tissue movements in healthy individuals, relevant for the understanding of the cerebrospinal-fluid (CSF) circulation and the pathogenesis of hydrocephalus, were thoroughly investigated.

  6. 4. Cardiopulmonary Resuscitation : Pharmacological Interventions for Augmentation of Cerebral Blood Flow

    Author : Jakob Johansson; Sten Rubertsson; Rolf Gedeborg; Sven-Erik Gisvold; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology and intensive care; Adrenaline epinephrine ; Cardiac arrest; Cardiopulmonary resuscitation; Cerebral blood flow; Guidelines; Post-resuscitation period; Vasopressin; Anestesiologi och intensivvård; Anaesthetics and intensive care; Anestesiologi och intensivvård;

    Abstract : Cardiac arrest results in immediate interruption of blood flow. The primary goal of cardiopulmonary resuscitation (CPR) is to re-establish blood flow and hence oxygen delivery to the vital organs. READ MORE

  7. 5. How to reduce the exposure to anticoagulants when performing haemodialysis in patients with a bleeding risk : a study of methods used in clinical practise

    Author : Malin Skagerlind; Bernd Stegmayr; Birgitta Olofsson; Fredrik Uhlin; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acute kidney injury; dialysis; hemorrhage; anticoagulation; Akut njursvikt; dialys; blödning; antikoagulation; medicin; Medicine;

    Abstract : When a patient suffers from kidney failure and also has an enhanced risk of bleeding, the standard haemodialysis (HD) treatment becomes a problem. When human blood comes in contact with artificial material, as in the tubing system and in the dialyser (the extra corporeal circuit, ECC), the coagulation system is activated. READ MORE
