  1. 1. Effects of nucleus pulposus on nerve root circulation and function. Morphologic and functional studies in an experimental model using porcine spinal nerve roots

    Sammanfattning : Sciatica due to lumbar disc herniation has for many decades been viewed as a consequence of mechanical compression exerted on spinal nerve roots by the bulging disc tissues. Recent research has, however, indicated that extruded nucleus pulposus (NP) from the intervertebral disc might cause functional and endoneurial morphological changes in spinal nerve roots, without mechanical compression.

  3. 2. 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

  4. 3. Ultrasound-guided regional anesthesia in children and adults: aspects on central and peripheral blocks

    Författare :Märit Lundblad; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The universal use of regional anesthesia has previously been hampered by fundamental factors, e.g. excessive failure rates, inability to detected anatomical variations and fear for unintentional tissue damage; all due to the inherent imprecision of previous localization techniques.

  5. 4. Spinal cord stimulation in chronic pain : a study of health outcomes and costs

    Författare :Emma Söreskog; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: The aetiology of chronic pain is complex and encompasses many different causes. Chronic pain commonly arises due to spinal disorders causing pain in the back and legs. LÄS MER

    Sammanfattning : Paediatric regional anaesthesia has gained widespread popularity during recent years because of an excellent potential for intra- and postoperative pain relief and reduction of the surgically induced stress response. The aim of the present thesis was to adapt and develop the technique of paravertebral blockade (PVB) for the safe use in paediatric patients and also to investigate aspects on plasma protein binding and toxicity of local anaesthetic drugs which might be of importance in the special settings of paediatric anaesthesia.
