Regional anaesthesia training in the UK - a national survey.

Background: Adequate training of anaesthetists in regional anaesthesia is important to ensure optimal patient access to regional anaesthesia. Methods: We undertook a national survey of UK trainee anaesthetists and Royal College of Anaesthetists (RCoA) tutors to assess experiences of training in regional anaesthesia. We performed descriptive statistics for baseline characteristics, and logistic regression of training indices and tutor confidence that their hospital could provide regional anaesthesia training at all three stages of the RCoA 2021 curriculum. Results: A total of 492 trainees (19.2%) and 114 tutors (45.2%) completed the survey. Trainees were less likely to have received training in chest/abdominal wall compared with upper/lower limb blocks {erector spinae vs femoral block (odds ratio [OR] 0.25, 95% confidence interval [CI] 0.16-0.39), P<0.001}, or achieved >20 chest/abdominal wall blocks by Stage 3 of training (chest vs lower limb block [OR 0.09, 95% CI 0.05-0.15, P<0.001]. There was a strong association between training received, number of blocks performed (>20 vs 0-5 blocks), and self-reported ability to perform blocks independently, OR 20.9 (95% CI 9.38-53.2). 24/182 (13%) and 10/182 (5.5%) of trainees had performed ≥50 non-obstetric lumbar and thoracic epidurals, respectively, by Stage 3 training. There was a positive association between having a lead clinician for regional anaesthesia, particularly those with paid sessions, and reported confidence to provide regional anaesthesia training at all stages of the curriculum (Stage 3 OR 7.27 [95% CI 2.64-22.0]). Conclusion: Our results confirm the importance of clinical experience and access to training in regional anaesthesia, and support the introduction of departmental regional anaesthesia leads to improve equity and quality in training opportunities.

Recommendations for anatomical structures to identify on ultrasound for the performance of intermediate and advanced blocks in ultrasound-guided regional anesthesia.

Recent recommendations describe a set of core anatomical structures to identify on ultrasound for the performance of basic blocks in ultrasound-guided regional anesthesia (UGRA). This project aimed to generate consensus recommendations for core structures to identify during the performance of intermediate and advanced blocks. An initial longlist of structures was refined by an international panel of key opinion leaders in UGRA over a three-round Delphi process. All rounds were conducted virtually and anonymously. Blocks were considered twice in each round: for "orientation scanning" (the dynamic process of acquiring the final view) and for "block view" (which visualizes the block site and is maintained for needle insertion/injection). A "strong recommendation" was made if ≥75% of participants rated any structure as "definitely include" in any round. A "weak recommendation" was made if >50% of participants rated it as "definitely include" or "probably include" for all rounds, but the criterion for strong recommendation was never met. Structures which did not meet either criterion were excluded. Forty-one participants were invited and 40 accepted; 38 completed all three rounds. Participants considered the ultrasound scanning for 19 peripheral nerve blocks across all three rounds. Two hundred and seventy-four structures were reviewed for both orientation scanning and block view; a "strong recommendation" was made for 60 structures on orientation scanning and 44 on the block view. A "weak recommendation" was made for 107 and 62 structures, respectively. These recommendations are intended to help standardize teaching and research in UGRA and support widespread and consistent practice.

Core outcome set for peripheral regional anesthesia research: a systematic review and Delphi study.

BACKGROUND/IMPORTANCE: There is heterogeneity among the outcomes used in regional anesthesia research. OBJECTIVE: We aimed to produce a core outcome set for regional anesthesia research. METHODS: We conducted a systematic review and Delphi study to develop this core outcome set. A systematic review of the literature from January 2015 to December 2019 was undertaken to generate a long list of potential outcomes to be included in the core outcome set. For each outcome found, the parameters such as the measurement scale, timing and definitions, were compiled. Regional anesthesia experts were then recruited to participate in a three-round electronic modified Delphi process with incremental thresholds to generate a core outcome set. Once the core outcomes were decided, a final Delphi survey and video conference vote was used to reach a consensus on the outcome parameters. RESULTS: Two hundred and six papers were generated following the systematic review, producing a long list of 224 unique outcomes. Twenty-one international regional anesthesia experts participated in the study. Ten core outcomes were selected after three Delphi survey rounds with 13 outcome parameters reaching consensus after a final Delphi survey and video conference. CONCLUSIONS: We present the first core outcome set for regional anesthesia derived by international expert consensus. These are proposed not to limit the outcomes examined in future studies, but rather to serve as a minimum core set. If adopted, this may increase the relevance of outcomes being studied, reduce selective reporting bias and increase the availability and suitability of data for meta-analysis in this area.

Bi-level erector spinae plane catheters for multiple rib fractures in a high-risk patient.

Rib fractures are associated with significant morbidity and mortality. Most of the morbidity stems from poorly controlled pain and therefore immobility and weak respiratory effort. Moreover, the number of injured ribs correlates with increasing risk of associated morbidity and mortality. We describe the analgesic management of an elderly co-morbid patient on oral anticoagulant therapy presenting with extensive multilevel rib fractures. According to the Western Trauma Association 2017 risk stratification, her mortality was as high as 20%. When a large number of ribs are involved, single level regional blocks may not provide sufficient local anesthetic spread to cover the extensive injury. Therefore, we employed erector spinae plane catheters at two levels. We believe that our therapeutic approach provided comprehensive, reliable and continuous analgesia, leading to a successful outcome in the case of our patient.
