A randomised placebo-controlled trial examining the effect on hand supination after the addition of a suprascapular nerve block to infraclavicular brachial plexus blockade
(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 ...
Minimum effective volume of ropivacaine 7.5mg/ml for an ultrasound-guided infraclavicular brachial plexus block
(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 ...
Atherosclerotic risk factors and risk of myocardial infarction and venous thromboembolism; Time-fixed versus time-varying analyses. The Tromsø Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-09-16)
<i>Background:</i> Single measurements of modifiable risk factors may underestimate associations with outcomes in cohorts. We aimed to compare risk estimates of myocardial infarction (MI) and venous thromboembolism (VTE) by atherosclerotic risk factors during long follow-up using time-fixed analyses without and with correction for regression dilution and time-varying analyses.<p> <p><i>Methods:</i> ...
Ischemic Stroke and Risk of Venous Thromboembolism in the General Population: The Tromsø Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-11-07)
<i>Background</i> - Even though clinical data support a relation between ischemic stroke and venous thromboembolism (VTE), the strength and time dependence of the association remain to be settled at the population level. We therefore aimed to investigate the association between ischemic stroke and VTE in a prospective population-based cohort.<p> <p><i>Methods and Results</i> - Participants (n=30 ...
Effect of genetically low 25-hydroxyvitamin D on mortality risk: Mendelian randomization analysis in 3 large European cohorts
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-02)
The aim of this study was to determine if increased mortality associated with low levels of serum 25-hydroxyvitamin D (25(OH)D) reflects a causal relationship by using a Mendelian randomisation (MR) approach with genetic variants in the vitamin D synthesis pathway. Individual participant data from three European cohorts were harmonized with standardization of 25(OH)D according to the Vitamin D ...
