• A combination of infraclavicular and suprascapular nerve blocks for total shoulder arthroplasty: A case series 

      Musso, Dario Davide; Klaastad, Øivind; Ytrebø, Lars Marius (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-27)
      Background - Shoulder arthroplasty is associated with significant post-operative pain. Interscalene plexus block is the gold standard for pain management in patients undergoing this surgery, however, alternatives are currently being developed. We hypothesized that a combination of anterior suprascapular nerve block and lateral sagittal infraclavicular block would provide effective post-operative ...

      BAKGRUNN - Formålet med undersøkelsen var å dokumentere forbruket av opioider ved to kirurgiske avdelinger ved Universitetssykehuset Nord-Norge Tromsø i perioden 2010–17.<p> <p>MATERIALE OG METODE - Forbruket av opioider ved Gastrokirurgisk avdeling og Avdeling for hjerte-, lunge- og karkirurgi ble innhentet fra Sykehusapotek Nord. Alle opioider ble omregnet til orale morfinekvivalenter.<p> ...
    • 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. ...
    • Pulmonary vascular clearance of harmful endogenous macromolecules in a porcine model of acute liver failure 

      Nedredal, Geir Ivar; Elvevold, Kjetil Helge; Chedid, MF; Ytrebø, Lars Marius; Rose, CF; Sen, S; Smedsrød, Bård; Jalan, R; Revhaug, Arthur (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-05-30)
      Background. Pulmonary complications are common in acute liver failure (ALF). The role of the lungs in the uptake of harmful soluble endogenous macromolecules was evaluated in a porcine model of ALF induced by hepatic devascularization (n = 8) vs. controls (n = 8). In additional experiments, pulmonary uptake was investigated in healthy pigs. Fluorochrome-labeled modified albumin (MA) was applied to ...
    • 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 ...
