  1. 21. Early Physiotherapy in the Neurointensive Care Unit - Passive Physiotherapy Interventions

    Författare :Annelie Thelandersson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiotherapy; Brain injury; Stroke; Intensive care unit; Prone position; Range of motion; Continuous passive motion; Intra cranial pressure; Cerebral perfuison pressure; Haemodynamics;

    Sammanfattning : Background: In critically ill patients, treated in the neurointensive care unit (NICU) because of severe brain injury or stroke, physical activities have been restricted to a minimum due to the potential risks of complications and adverse events. Nevertheless, passive physiotherapy treatments are widely used without conclusive evidence for their safety. LÄS MER

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

    Författare :Silvana Naredi; Göteborgs universitet; []
    Nyckelord :traumatic brain injury; brain edema; microcirculation; intracranial pressure; epo-prostenol; norepinephrine; subarachnoid hemorrhage; sympathetic nervous system; clonidine;

    Sammanfattning : 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. LÄS MER

  3. 23. Cerebral intraventricular hemorrhage and post-hemorrhagic ventricular dilatation in preterm infants: new mechanistic insights and potential treatment strategies

    Författare :Olga Romantsik; Lund Pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prematurity; Intraventricular hemorrhage; Post-hemorrhagic ventricular dilatation; White matter injury; Gray matter injury; Preterm rabbits; Extracellular hemoglobin; a-1-microglobulin; animal IVH models; High frequency ultrasound; MRI; corticogenesis;

    Sammanfattning : Intraventricular hemorrhage (IVH) is one of the major co-morbidities of premature birth associated with post-hemorrhagic ventricular dilatation (PHVD) development, long-term neurodevelopmental impairment, behavioral problems, special educational needs, and dependency on social security.Hypothesis and aims: We believe that extravasated blood and further release of extracellular hemoglobin (Hb) are crucial in brain injury following IVH and consequent development of PHVD.

  4. 24. Physiological and pathophysiological cerebrovascular regulation monitored by transcranial doppler

    Författare :Gunnar Hellström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Transcranial Doppler ultrasonography (TCD) became available in the middle of the 1980s as a new technique for examining cerebral circulation. With this technique it is possible to measure the velocity of blood flow in major cerebral arteries. LÄS MER

  5. 25. Pediatric caudal anesthesia with reference to spread and intracranial effects

    Författare :Paul Castillo; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Caudal anesthesia is, since 1933, the most common regional anesthetic technique used in children and has hitherto been described as a safe and straightforward method. Recent research has shown that a high-dose (1. LÄS MER
