- ItemComparison of Continuous Popliteal Nerve Blocks Using Lidocaine versus Bupivacaine Infusions for Ambulatory Foot Surgery: A Randomized, Double-blind, Noninferiority Trial(2023) Echevarría, Ghislaine; Altermatt Couratier, Fernando René; Miranda Hiriart, Pablo; Araneda Vilches, Andrea Lucía; Corvetto Aqueveque, Marcia Antonia; De La Fuente Sanhueza, René Francisco; Cuadra F., Juan Carlos de laBackground 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.
- ItemCross-cultural adaptation and validation of the Spanish version of the Anesthetists' Non-Technical Skills (ANTS) assessment tool(2023) Delfino Yurin, Alejandro Eugenio; Fuentes López, Eduardo A.; De La Fuente Sanhueza, René Francisco; Altermatt Couratier, Fernando RenéStudy objective: Establish the transcultural validity of Anesthetists Non-Technical Skills (ANTS) in a Spanish-speaking country. Design: Prospective cohort. Setting: Clinical simulation center. Subjects: Forty-two Anesthesia PY2 and PY3 residents participated in the study. Interventions: Four clinical scenarios simulating anesthesia crises were assessed with a Spanish version of ANTS. Every simulated scenario was run twice with a time span of 3 to 4 months between them. Measurements: Two anesthesiologists independently assessed all simulated sessions using ANTS. The ANTS indicators of construct validity were obtained by confirmatory factor analysis. Various goodness-of-fit indices of the factorial model were calculated: Comparative Fit Index (CFI); Tucker-Lewis Adjustment Index (TLI) and Root Mean Square Error of Approximation (RMSEA). The standardized factor loadings and the determination coefficient (R2) was also estimated. Main results: A total of 212 clinical scenarios were analyzed. The specified factorial model had the same grouping of elements in four domains as the original version of ANTS. The CFI index and the TLI were 0.99 and the RMSEA reached 0.07 (95% CI 0.06–0.08). All the standardized factor loadings were found to be >0.4. Also, the elements obtained an R2 value that fluctuated between 0.54 and 0.92. Conclusions: The Spanish version of ANTS is a valid, reliable and a useful tool to assess non-technical skills in Spanish-speaking countries. The applicability of the instrument was comparable to the original setting. The high reliability of ANTS in our setting allows us to propose its use not just in an educational and research setting; it can be used as an assessment tool of non-technical skills.
- ItemProcess-oriented instrument and taxonomy for teaching surgical procedures in medical training: The ultrasound-guided insertion of central venous catheterGálvez, Víctor; De La Fuente Sanhueza, René Francisco; Meneses, César; Leiva, Luis; Fagalde, Gonzalo; Herskovic, Valeria; Fuentes, Ricardo; Muñoz Gama, Jorge; Sepúlveda, MarcosProcedural training is relevant for physicians who perform surgical procedures. In the medical education field, instructors who teach surgical procedures need to understand how their students are learning to give them feedback and assess them objectively. The sequence of steps of surgical procedures is an aspect rarely considered in medical education, and state-of-the-art tools for giving feedback and assessing students do not focus on this perspective. Process Mining can help to include this perspective in this field since it has recently been used successfully in some applications. However, these previous developments are more centred on students than on instructors. This paper presents the use of Process Mining to fill this gap, generating a taxonomy of activities and a process-oriented instrument. We evaluated both tools with instructors who teach central venous catheter insertion. The results show that the instructors found both tools useful to provide objective feedback and objective assessment. We concluded that the instructors understood the information provided by the instrument since it provides helpful information to understand students' performance regarding the sequence of steps followed.
