Abstract:
There is no universally agreed set of anatomical structures that must be
identified on ultrasound for the performance of ultrasound-guided regional anesthesia (UGRA) techniques. This study aimed to produce standardized
recommendations for core (minimum) structures to identify during seven basic blocks. An international consensus was sought through a modified Delphi
process. A long-list of anatomical structures was refined through serial review by key opinion leaders in UGRA. All rounds were conducted remotely
and anonymously to facilitate equal contribution of each participant. Blocks were considered twice in each round: for “orientation scanning” (the dynamic
process of acquiring the final view) and for the “block view” (which visualizes the block site and is maintained for needle insertion/injection).
Strong recommendations for inclusion were made if ≥75% of participants rated a structure as “definitely include” in any round. Weak recommendations were
made if 〉 50% of participants rated a structure as “definitely include” or
“probably include” for all rounds (but the criterion for “strong recommendation” was never met). Thirty-six participants (94.7%) completed
all rounds. 128 structures were reviewed; a “strong recommendation” is made for 35 structures on orientation scanning and 28 for the block view. A “weak
recommendation” is made for 36 and 20 structures, respectively. This study provides recommendations on the core (minimum) set of anatomical structures
to identify during ultrasound scanning for seven basic blocks in UGRA. They are intended to support consistent practice, empower non-experts using basic
UGRA techniques, and standardize teaching and research.
