  1. 1. Opioids and regulation of breathing

    Författare :Åsa Österlund Modalen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Sameridine; partial - opioid agonist; local anesthetic; morphine; ventilation; respiratory depression; hypercarbia; hypoxia; frakefamide; peripheral -opioid agonist;

    Sammanfattning : A most important challenge even in modern medicine is effective treatment of pain. Respiratory depression is the most feared side effect of analgesic treatment in the clinical situation. LÄS MER

  3. 2. On the interaction between a neuromuscular blocking agent and regulation of breathing during hypoxia

    Författare :Nicholas Wyon; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Neuromuscular block; TOF ratio; vecuronium; ventilatory response; chemoreceptors; carotid body;

    Sammanfattning : It was previously generally agreed that a mechanical train-of-four (TOF) ratio >0.70 represented an adequate recovery of respiratory function after neuromuscular blockade. Normal respiratory parameters at this level of recovery and during air breathing support this view. LÄS MER

  4. 3. The Effect of CO2-Pneumoperitoneum on Ventilation Perfusion Distribution of the Lung

    Författare :Christof Strang; Göran Hedenstierna; Suzanne Odeberg-Wernerman; Uppsala universitet; []
    Nyckelord :lung; atelectasis; computed tomography; multiple inert gas elimination technique; model; pig; Pa–ECO2 ratio; surgery; laparoscopy; lung; blood flow; single photon emission computed tomography; ventilation perfusion distribution; gas exchange; hypoxic pulmonary vasoconstriction; MEDICINE; MEDICIN;

    Sammanfattning : Laparoscopic operations are a common and popular way for abdominal procedures. They are usually performed by insufflation of carbon dioxide (CO2) into the abdominal cavity. However, insufflation of CO2 may interfere with cardiac and circulatory as well as respiratory functions. The CO2-pneumoperitoneum (PP) may cause hypercarbia and acidosis. LÄS MER

  5. 4. Studies on the halothane-diethyl-ether azeotrope

    Författare :Sigga Kalman; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Requirements for a safe standard for anaesthesia under primitiveconditions differ from those under peaceful circumstances. It is important not to blunt the reflexes that guard vital functions. LÄS MER

  7. 5. Studies of diaphragm fatigue and dysfunction

    Författare :Peter J Radell; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Diaphragm function; contractility; fatigue; oxidative metabolism; 31phosphorus nuclear magnetic spectroscopy; ultrasonography; prolonged ventilation; compound muscle action potential; myopathy; electroneurography; muscle fiber; morphology.;

    Sammanfattning : Diaphragm fatigue and dysfunction are important components of acute and chronic respiratory pump failure. We lack knowledge about the nature of diaphragm fatigue and the pathophysiological and morphological changes that occur in the diaphragm after prolonged mechanical ventilation. This thesis studied two aspects of diaphragm function. LÄS MER
