  1. 1. Severe Hemodilution - Clinical and Experimental Studies

    Författare :Valéria Perez de Sá; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; shivering; critical oxygen delivery; oxygen consumption; child; dextran; hypothermia; hemodilution; anemia; Anaesthesiology; intensive care; Anestesiologi; intensivvård; lactates;

    Sammanfattning : In children, it is often desirable to minimize allogenic blood transfusion, and this thesis explores the physiology of an alternative method of managing perioperative blood loss: hemodilution with Ringer´s dextran. Methods Clinical studies: Arterial pressure, superior caval venous oxygen saturation (ScvO2) and blood lactate concentration (L) were studied during bone marrow harvesting (BMH) on 23 occasions in 19 children, 1-17 years of age, with healthy hearts and lungs.

  3. 2. Cardiovascular response to hyperoxemia, hemodilution and burns : a clinical and experimental study

    Författare :Zoltan Bak; Birgitta Janerot Sjöberg; Robert Hahn; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anesthesia; general; Burns; Echocardiography; transesophageal; Hemodilution; emodynamic processes; Hyperoxia; Intensive care; Intensivvård;

    Sammanfattning : The last decades less invasive monitoring and analytical tools have been developed for the evaluation of myocardial mechanics in clinical praxis. In critical care, these are longed-for complements to pulmonary artery catheter monitoring, additionally offering previously inaccessible information. LÄS MER

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

    Författare :Lieselotte Frost-Arner; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 4. Viscoelastic haemostatic assays and fibrinogen concentration tests during haemodilution: The effects of fibrinogen and factor XIII

    Författare :Dag Winstedt; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; thrombelastography; fibrinogen; factor XIII; free oscillatioin rheometry; hemodilution; hypothermia;

    Sammanfattning : Background: The efficacy of concentrates of fibrinogen and factor XIII in hypothermia and haemodilution has not yet been completely investigated. Clauss methods have not previously been evaluated perioperatively. LÄS MER

  7. 5. Stroke : patient characteristics, efficacy of a stroke unit and evaluation of hemodilution therapy

    Författare :Tage Strand; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acute cerebrovascular disease; blood viscosity; cerebral infarction; hemodilution therapy; stroke unit;

    Sammanfattning : Stroke is a major health problem in all developed countries. These studies, performed in a stroke unit at a medical department, were designed to characterize essential clinical features of the different cerebrovascular disorders on admission to hospital, to evaluate the efficacy of admitting unselected stroke patients to a stroke unit and, to evaluate hemodilution as a therapeutical regime in patients with cerebral infarction.
