    • Minimum effective volume of ropivacaine 7.5mg/ml for an ultrasound-guided infraclavicular brachial plexus block 

      Flohr-Madsen, Sandra; Ytrebø, Lars Marius; Kregnes, Sylvia Beate; Wilsgaard, Tom; Klaastad, Øivind (Journal article; Tidsskriftartikkel; Peer reviewed, 2013-02-18)
      <p><i>Background - </i>Ultrasound guidance has been shown to reduce the minimum effective volume (MEV) of local anaesthetics for several peripheral nerve blocks. Although the lateral sagittal infraclavicular block (LSIB) is a well‐established anaesthesia method, MEV for this technique has not been established. Our aim with this study was to determine the MEV using ropivacaine 7.5 mg/ml for the LSIB ...

    • A novel combination of peripheral nerve blocks for arthroscopic shoulder surgery 

      Musso, Dario Davide; Flohr-Madsen, Sandra; Meknas, Khaled; Wilsgaard, Tom; Ytrebø, Lars Marius; Klaastad, Øivind (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-08-04)
      <p><i>Background - </i>Interscalene brachial plexus block is currently the gold standard for intra‐ and post‐operative pain management for patients undergoing arthroscopic shoulder surgery. However, it is associated with block related complications, of which effect on the phrenic nerve have been of most interest. Side effects caused by general anesthesia, when this is required, are also a concern. ...

    • A randomised placebo-controlled trial examining the effect on hand supination after the addition of a suprascapular nerve block to infraclavicular brachial plexus blockade 

      Flohr-Madsen, Sandra; Ytrebø, Lars Marius; Valen, Katrin; Wilsgaard, Tom; Klaastad, Øivind (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-07-11)
      Some surgeons believe that infraclavicular brachial plexus blocks tends to result in supination of the hand/forearm, which may make surgical access to the dorsum of the hand more difficult. We hypothesised that this supination may be reduced by the addition of a suprascapular nerve block. In a double‐blind, randomised, placebo‐controlled study, our primary outcome measure was the amount of supination ...

    • Studies of peripheral nerve blocks for hand and shoulder surgery 

      Flohr-Madsen, Sandra (Doctoral thesis; Doktorgradsavhandling, 2019-04-04)
      Performing regional anesthesia with a minimum effective volume (MEV) of local anesthetic may reduce the risk of systemic local anesthesia toxicity. The lateral sagittal infraclavicular block (LSIB) is a well-established anesthesia method for surgery distal to the shoulder. For LSIB using ropivacaine 7.5 mg/ml the MEV was previously not known and we estimated MEV95 to be 31 ml (95% CI, 18 – 45 ...
