Coffee consumption and work satisfaction among Scandinavian anaesthesiologists: A survey.
It is a common prejudice that anaesthetic doctors are believed to have high coffee consumption. In this study, we aimed to assess the association between coffee drinking and work satisfaction among Scandinavian anaesthesiologists. We hypothesised that coffee consumption was positively correlated with work satisfaction. ⋯ In this survey, we found high work satisfaction among Scandinavian anaesthesiologists, with no difference between coffee and non-coffee drinkers.

Randomized Controlled Trial Comparative StudyOropharyngeal leak pressure of the LMA Protector™ vs the LMA Supreme™; a prospective, randomized, controlled clinical trial.
Clinical characteristics such as oropharyngeal leak pressure (OLP) and ventilation peak pressure are important factors for successful use of supraglottic airway devices in general anaesthesia. We hypothesized that the LMA Protector™ compared to the LMA Supreme™ may develop a higher OLP, which could be of clinical significance. ⋯ The LMA Protector™ enabled a higher OLP compared to the LMA Supreme™. This finding may be important for patients requiring a higher peak pressure for sufficient supraglottic airway device ventilation.

Randomized Controlled TrialRemote real-time supervision via tele-ultrasound in focused cardiac ultrasound: A single-blinded cluster randomized controlled trial.
Supervision via tele-ultrasound presents a remedy for lacking on-site supervision in focused cardiac ultrasound, but knowledge of its impact is largely absent. We aimed to investigate tele-supervised physicians' cine-loop quality compared to that of non-supervised physicians and compared to that of experts. ⋯ Tele-supervised physicians performed scans of better quality than non-supervised physicians. The present study supports the use of tele-supervision for physicians with basic focused ultrasound competence in a setting where on-site supervision is unavailable.

Randomized Controlled TrialPulmonary haemodynamics and right ventricular function in cemented vs uncemented total hip arthroplasty-A randomized trial.
Bone cement implantation syndrome (BCIS) is a feared complication in orthopaedic surgery with a huge impact on post-operative morbidity. In this randomized trial, we evaluated the effects of bone cement on pulmonary and systemic haemodynamics in patients receiving either cemented or uncemented hip arthroplasty for isolated femoral neck fracture. ⋯ The use of bone cement in total hip arthroplasty increases pulmonary vascular resistance and the afterload of the RV with potentially negative effects on RV performance.

Brachial plexus block of the posterior and the lateral cord using ropivacaine 7.5 mg/mL.
We recently showed that the novel combination of a superficial cervical plexus block, a suprascapular nerve block, and the lateral sagittal infraclavicular brachial plexus block (LSIB) provides an alternative anaesthetic method for arthroscopic shoulder surgery. In this study, we hypothesised that the LSIB dose for this shoulder block could be significantly reduced by injecting only towards the shoulder relevant posterior and lateral cords. Our aim was to determine the minimum effective volume in 50% of the patients (MEV50 ) and to estimate the MEV95, when using ropivacaine 7.5 mg/mL to block these cords. ⋯ For single-deposit infraclavicular posterior and lateral cord block, the MEV95 of ropivacaine 7.5 mg/mL was estimated to 9.0 mL.
