Anesthesiologists ultrasound-guided regional anesthesia core curriculum: a Delphi consensus from Italian regional anesthesia experts.

Abstract

Introduction: The need for a standardized core curriculum in regional anesthesia has become essential, particularly with the integration of ultrasound revolutionizing and exponentially increasing clinical practice and possibilities. In fact, numerous novel techniques, often overlapping, can confuse practitioners. This study aims to establish a core curriculum for upper limb, lower limb, paraspinal and fascial plane blocks for residency training, addressing potential educational gaps caused by the multitude of techniques, through a Delphi consensus process involving recognized Italian regional anesthesia experts.

Methods: A steering committee was formed in order to select a panel of experts in regional anesthesia. A three-round Delphi consensus was planned: two rounds of electronic voting and a final round of mixed electronic voting and round table discussion. The consensus was defined as ≥ 75% agreement for inclusion and lower than ≤ 25% agreement for exclusion from the core curriculum list. Techniques reaching the 50% threshold were included with low consensus.

Results: Twenty-nine techniques were selected to be included in the ultrasound-guided regional anesthesia core curriculum. Twenty-two were included with strong consensus: Upper limb: interscalene brachial plexus block, supraclavicular brachial plexus block, infraclavicular brachial plexus block, axillary brachial plexus block, intermediate cervical plexus block Lower limb: femoral nerve block, pericapsular nerve group block, adductor canal block, sciatic nerve block (transgluteal approach, infragluteal approach, and at the popliteal fossa), ankle block Paraspinal/fascial plane blocks: erector spinae plane block, deep serratus anterior plane block, superficial pectointercostal plane block, interpectoral plane block, pectoserratus plane block, rectus sheath block, ilioinguinal iliohypogastric nerves block, transversus abdominis plane block (with subcostal and midaxillary approaches) The remaining seven techniques were included with low consensus: superficial cervical plexus block, lumbar plexus block, fascia iliaca block (suprainguinal approach), anterior quadratus lumborum block, lateral quadratus lumborum block, paravertebral block, and serratus anterior plane block.

Conclusions: This curriculum aims to standardize training and ensure that residents acquire the essential skills required for effective and safe practice regardless of the residents' subsequent specialization. By incorporating these techniques, educational programs can provide a structured and consistent approach to regional anesthesia, enhancing the quality of patient care and improving outcomes.
