A survey of anaesthetic management of regional anaesthesia for patients undergoing arthroscopic shoulder surgery in Australia.
Article in BMC anesthesiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe Australian and New Zealand College of Anaesthetists recommends standards of monitoring and conduct for regional anaesthesia but does not endorse specific regional techniques. While the interscalene block is the de-facto standard technique, there are numerous established and novel alternatives. Regional block choice and block-related variables (local anaesthetic type, dose, volume, adjuncts) are subject to individual and institutional practices.
methodsUsing a 30-question survey, we aimed to create a snapshot of current regional anaesthesia practice for patients undergoing arthroscopic shoulder surgery across Australia and New Zealand.
resultsAmong 134 anaesthetist respondents, 85.1% routinely placed a regional block for arthroscopic shoulder surgery. 91.2% performed interscalene blocks. Ropivacaine 0.375% and 0.75% were the most common concentrations and type. Regional anaesthesia under light sedation and general anaesthesia were performed by 47.4% and 30.7% block-respondents respectively. 96.5% of block-respondents used ultrasonography. 49.1% of block-respondents recorded written consent. 86.0% always performed a consent/site/side check. Standard monitoring was variably applied for blood pressure, electrocardiography and end-tidal carbon dioxide monitoring. Postoperatively, patient-controlled analgesia was not routinely prescribed.
conclusionVariation exists for regional anaesthesia techniques for arthroscopic shoulder surgery with most performing interscalene blocks with ultrasonography. This study highlights topics of debate including level of consciousness during block performance and overall adherence to monitoring recommendations, so as to ensure patient and anaesthetist safety is upheld. CLINICAL TRIAL NUMBER: Not applicable.
