Algoritmos de seguridad para bloqueos guiados por ecografía: el próximo reto Sr. Director: We read with interest two recent publications, the letter by Fito et al. 1 on the intraneural approach of the sciatic nerve at the popliteal fossa and the case series by Bilbao et al. 2 about interescalene and supraclavicular blocks of Safe procedure for ultrasound guided nerve block Nerve identification

BACKGROUND Our aim was to review the recent evidence for the efficacy of peripheral regional anaesthesia. METHODS Following a systematic literature search and selection of publications based on prospectively agreed upon criteria, we produced a narrative review of the most commonly performed peripheral regional anaesthetic blocks for surgery on the upper limb, the lower limb, and the trunk. We...

Ultrasound-guided supraclavicular brachial plexus block using 1% and 2% lidocaine in 21 procedures is reported. Average procedure time was 5.1 minutes (± 1.2 min; range, 2-8 min). Average time of onset and duration were 4.8 minutes (± 3.7 min; range, 0-10 min) and 77.9 minutes (± 26.7 min; range, 44-133 min), respectively, for sensory block and 8.4 minutes (± 5.7 min; range, 3-23 min) and 99 mi...

Dr Nair’s letter to the editor regarding the failed nerve blocks mentioned in our paper, “Comparison of the supraclavicular, infraclavicular and axillary approaches for ultrasound-guided brachial plexus block for surgical anesthesia”,1 raised several points that I believe are worth looking at in more detail. We are grateful for Dr Nair’s comments which have contributed to the furthering of scho...
