    Background and objectives: Continuous sciatic popliteal nerve block effectivelymanages pain after ankle and foot surgery. Most studies on continuous infusionof local anesthetics by perineural catheters have been made with bupivacaine,levobupivacaine, and ropivacaine, but lidocaine has not been used. The mainobjective of this study was to compare the quality of analgesia, motor function,and side effects between lidocaine and bupivacaine infusions in bilateralcontinuous popliteal nerve blocks for foot surgery.Methods: This was a prospective, double-blind, randomized, parallel-group,noninferiority study. We enrolled 70 patients undergoing bilateral foot or anklesurgery that could be performed under general anesthesia and continuous regionalanalgesia using sciatic popliteal nerve blocks. During their postoperative care, theywere randomized into 2 groups: group lidocaine (lidocaine 0.5%, 5 ml/h) or groupbupivacaine (bupivacaine 0.1%, 5 ml/h), administered through elastomeric pumps.The primary outcome was pain at 24 h after surgery, assessed by a verbal numericrating scale (ranging from 0 to 10). A pre-specified non-inferiority margin of 1.5 wasdefined. Secondary outcomes were the degree of motor and sensitive block, totalopioid use, and difficulties with pump or catheter management.Results: The mean postoperative pain at 24 h of surgery was 2.06 (95% bootstrapconfidence interval bCI 1.29, 2.83) and 1.82 (95% bCI 1.02, 2.62) in the lidocaineand bupivacaine group, respectively. The upper limit of the 95% bCI for the meandifference between lidocaine and bupivacaine was 0.82, declaring non-inferiority.No differences in the postoperative rescue analgesia use and satisfaction withcare were found. No differences in postoperative NRS, sensory block and motorblock were seen between groups.Conclusions: Lidocaine 0.5% and bupivacaine 0.1% provide similar postoperativeanalgesia through a sciatic popliteal catheter in ambulatory bilateral foot surgery patients.

    Simulation-based mastery learning of bronchoscopy-guided percutaneous dilatational tracheostomy competency acquisition and skills transfer to a cadaveric model
    (2021) Kattan Tala, Eduardo José; De la Fuente Sanhueza, René; Putz de la Fuente, Francisca Carolina; Vera Alarcón, María Magdalena; Corvetto Aqueveque, Marcia Antonia; Inzunza, Oscar; Achurra Tirado, Pablo; Inzunza Agüero, Martín Alejandro; Muñoz Gama, Jorge; Sepúlveda Fernández, Marcos Ernesto; Gálvez Yanjarí, Víctor Andrés; Pavez, Nicolás; Retamal Montes, Jaime; Bravo Morales, Sebastián
    Introduction: Although simulation-based training has demonstrated improvement of procedural skills and clinical outcomes in different procedures, there are no published training protocols for bronchoscopy-guided percutaneous dilatational tracheostomy (BG-PDT). The objective of this study was to assess the acquisition of BG-PDT procedural competency with a simulation-based mastery learning training program, and skills transfer into cadaveric models. Methods: Using a prospective interventional design, 8 trainees naive to the procedure were trained in a simulation-based mastery learning BG-PDT program. Students were assessed using a multimodal approach, including blind global rating scale (GRS) scores of video-recorded executions, total procedural time, and hand-motion tracking–derived parameters. The BG-PDT mastery was defined as proficient tracheostomy (successful procedural performance, with less than 3 puncture attempts, and no complications) with GRS scores higher than 21 points (of 25). After mastery was achieved in the simulator, residents performed 1 BG-PDT execution in a cadaveric model. Results: Compared with baseline, in the final training session, residents presented a higher procedural proficiency (0% vs. 100%, P < 0.001), with higher GRS scores [8 (6–8) vs. 25 (24–25), P = 0.01] performed in less time [563 (408–600) vs. 246 (214–267), P = 0.01] and with higher movement economy. Procedural skills were further transferred to the cadaveric model. Conclusions: Residents successfully acquired BG-PDT procedural skills with a simulation-based mastery learning training program, and skills were effectively transferred to a cadaveric model. This easily replicable program is the first simulation-based BG-PDT training experience reported in the literature, enhancing safe competency acquisition, to further improve patient care.

    Which types of peripheral nerve blocks should be included in residency training programs?
    (2015) Corvetto Aqueveque, Marcia Antonia; Echevarría, Ghislaine C.; Altermatt, Fernando; Espinoza, Ana M.; Corvetto Aqueveque, Marcia Antonia; Echevarria, Ghislaine C.; Altermatt, Fernando; Espinoza, Ana M.
    Abstract Background Despite the increasing use of regional anesthesia, specific recommendations regarding the type of procedures to be included in residency training programs are not currently available. We aimed to determine the nerve block techniques that practicing Chilean anesthesiologists perceived as essential to master during residency training. Methods After institutional ethics committee approval, an online survey was sent to 154 anesthesiologists that graduated between 2005–2012, from the two largest university residency programs in Chile. Multiple-choice questions elicited responses concerning the use of regional anesthesia. Results A total of 109 questionnaires were completed, which corresponded to a response rate of 70.8%. Almost all (98.2%) of the respondents used regional anesthesia in their clinical practice, 86.7% regularly performed peripheral nerve blocks (PNBs) and 51% used continuous PNB techniques. Residency programs represented their primary source of training. The most common PNB techniques performed were interscalene (100%), femoral (98%), popliteal sciatic (93%), and Bier block (90%). Respondents indicated that they were most confident performing femoral (98%), Bier block (90%), interscalene (90%), and popliteal sciatic (85%) blocks. The PNBs perceived as essential for their actual clinical practice were femoral (81%), interscalene (80%), popliteal sciatic (76%), and Bier blocks (62%). Conclusions Requesting information from former anesthesiology residents may be a source of information, guiding the specific types of PNBs that should be included in residency training. Other groups can easily replicate this methodology to create their own evidence and clinical practice based guidelines for residency training programs.Abstract Background Despite the increasing use of regional anesthesia, specific recommendations regarding the type of procedures to be included in residency training programs are not currently available.
