  1. 1. 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

  3. 2. Neuromuscular adaptations to muscle fatigue during submaximal isometric contractions in man

    Författare :Wolfgang N Löscher; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :isometric; electromyography; tremor; H-reflex; twitch; motoneuron; recruitment; la-afferents; recurrent inhibition; central fatigue; excitatory drive; gastrocnemius; soleus; triceps surae; tendon vibration; ischemia; Renshaw cellStockholm 1995;

    Sammanfattning : During a sustained contraction, the force producing capacity of a muscle gradually decreases. In order to maintain a constant force output, the neuromuscular system has to adapt to the contractile fatigue process. LÄS MER

  4. 3. Nicotinic transmission and drugs in anesthesia : neuromuscular blocking agents and propofol : consequences for carotid body function

    Författare :Malin Jonsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Carotid body; chemoreceptors; neuromuscular blocking agents; propofol; acetylcholine; nicotinic acetylcholine receptors;

    Sammanfattning : The carotid body is the global oxygen sensor of the human body. Acute hypoxia elicits instant hyperventilation mediated from the carotid body type 1 cells, where nicotinic transmission is a key component in oxygen sensing and signalling. LÄS MER

  5. 4. Neuromuscular function in the normal and inflamed colon. An experimental study in rat

    Författare :Lars Börjesson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ATP; dextran sulphate sodium; DMPP; enteric nervous system; McN-A-343; nitric oxide; non-adrenergic; rat; second messenger; smooth muscle; VIP;

    Sammanfattning : Neuromuscular function of the longitudinal muscle layer of distal colon was investigated in segments from normal rats and from rats with colitis induced by dextran sulphate sodium (DSS) at 3% for 3 or 7 days or 5% for 7 days. The study was performed in vitro, on spontaneous tone, or after precontraction. LÄS MER

  7. 5. Hypnosis monitoring during general anaesthesia : with focus on awareness

    Författare :Andreas Ekman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Hypnosis monitoring; electroencephalogram; BIS; AAI; neuromuscular block;

    Sammanfattning : An objective measure of the hypnotic component of general anaesthesia has been sought for decades. The electroencephalogram (EEG) was early recognized as a possible useful intraoperative monitor when the effects of anaesthetic drugs on human EEG recordings were noted. LÄS MER
