  1. 1. The Microcirculation in Trauma and Sepsis

    University dissertation from Anaesthesiology and Intensive Care

    Author : Peter Bansch; Lunds universitet.; Lund University.; [2013]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; microcirculation; prostacyclin; plasma vilume; trauma; sepsis; sidestream darkfield imaging; albumin; volume expansion; transcapillary escape rate; glycocalyx; charge;

    Abstract : The microcirculation plays a vital part for fluid-, gas- and solute-exchange, and changes in permeability during trauma or sepsis, that are in part necessary for the natural healing process, may also cause hypovolemia and edema formation, leading to disturbances in microvascular exchange. This thesis discusses changes is microvascular flow, permeability and plasma volume (PV) loss after experimental or surgical trauma and experimental sepsis. READ MORE

  2. 2. Studies on sitting pressure and buttock microcirculation : aiming at developing an alarm in the prevention of pressure ulcers in patients with spinal cord injuries

    University dissertation from Institutionen för biomedicin och kirurgi

    Author : Johan Thorfinn; Linköpings universitet.; Linköpings universitet.; [2006]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Blood supply; Buttocks; Hyperemia; Ischemia; Laser-Doppler flowmetry; Microcirculation; Posture physiology; Pressure; Skin blood supply; VETERINARY MEDICINE Medicine; VETERINÄRMEDICIN Medicin;

    Abstract : Pressure ulcers in patients with spinal cord injuries are a major problem, the prevalence in this group being reported as high as 20 – 30 percent. Most pressure ulcers develop around the pelvic girdle, and the key-contributing factor in the development of pressure ulcers is ischaemia due to longstanding pressure. READ MORE

  3. 3. Factors influencing splanchnic microcirculation in animal models of endotoxaemia

    University dissertation from Stockholm : Karolinska Institutet, Dept of Clinical Science, Intervention and Technology

    Author : Andreas Andersson; Karolinska Institutet.; Karolinska Institutet.; [2011]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microcirculation;

    Abstract : Even though severe sepsis and septic shock therapy has improved in recent years, mortality remains high (22-50%). Disturbances in splanchnic organ homeostasis and increases in gut permeability have long been presumed to contribute to systemic inflammation and multiple organ dysfunction syndrome in critical illness and septic shock.

  4. 4. Optical Monitoring of Cerebral Microcirculation

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Peter Rejmstad; Linköpings universitet.; Linköpings universitet.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical monitoring; cerebral microcirculation; diffuse reflectance spectroswcopy DRS ; laser Doppler flowmetry LDF ;

    Abstract : The cerebral microcirculation consists of a complex network of small blood vessels that support nerve cells with oxygen and nutrition. The blood flow and oxygen delivery in the microcirculatory blood vessels are regulated through mechanisms which may be influenced or impaired by disease or brain damage resulting from conditions such as brain tumors, traumatic brain injury or subarachnoid hemorrhage (SAH).

  5. 5. Cerebral circulation and the sympathetic nervous system in patients with traumatic brain injury or subarachnoid hemorrhage

    University dissertation from Göteborg

    Author : Silvana Naredi; Göteborgs universitet.; Gothenburg University.; [2000]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatic brain injury; brain edema; microcirculation; intracranial pressure; epo-prostenol; norepinephrine; subarachnoid hemorrhage; sympathetic nervous system; clonidine;

    Abstract : Maintenance of adequate cerebral microcirculation is necessary to avoid cerebral ischemia after severe traumatic brain injury and non-traumatic subarachnoid hemorrhage. After severe traumatic brain injury the blood-brain-barrier is disrupted and transcapillary leakage will contribute to the development of vasogenic brain edema. READ MORE
