    Assessment of central venous catheterization in a simulated model using a motion-tracking device: an experimental validation study
    (2016) Varas, Julián; Achurra Tirado, Pablo; León, Felipe.; Castillo, Richard.; De La Fuente, Natalia.; Aggarwal, Rajesh.; Clede, Leticia.; Bravo, María P.; Corvetto Aqueveque, Marcia Antonia; Montaña Rodríguez, Rodrigo
    Abstract Background Central venous catheterization (CVC) is a basic requirement for many medical specialties. Simulated training in CVC may allow the acquisition of this competency but few reports have established a valid methodology for learning and acquiring procedural skills for CVC. This study aims to validate the use of a tracking motion device, the imperial college surgical assessment device (ICSAD), by comparing it with validated global rating scales (GRS) to measure CVC performance in a simulated torso. Methods Senior year medical students, first and last year residents (PGY1, LYR), and expert anesthesiologists performed a jugular CVC assessment in a simulated model (Laerdal IV Torso). A validated GRS for objective assessment of technical skills and motion analysis by ICSAD was used. Statistical analysis was performed through Mann–Whitney and Kruskal–Wallis tests for construct validity and Spearman correlation coefficients between the ICSAD and GRS scores for concurrent validity between both. Results 32 subjects were recruited (10 medical students, 8 PGY1, 8 LYR and 8 experts). Total path length measured with ICSAD and GRS scores were significantly different between all groups, except for LYR compared to experts (p = 0.664 for GRS and p = 0.72 for ICSAD). Regarding jugular CVC procedural time, LYR and experts were faster than PGY1 and MS (p < 0.05). Spearman correlation coefficient was −0.684 (p < 0.001) between ICSAD and GRS scores. Conclusions ICSAD is a valid tool for assessment of jugular CVC since it differentiates between expert and novice subjects, and correlates with a validated GRS for jugular CVC in a simulated torso.Abstract Background Central venous catheterization (CVC) is a basic requirement for many medical specialties.

    Impacto de la implantación y desarrollo de la analgesia epidural administrada por la paciente para el tratamiento del dolor del parto. Encuesta en un hospital universitario en Chile
    (2013) Lacassie Quiroga, Héctor; Ferdinand Olivares, Constanza; Moreno, Duby; Montaña Rodríguez, Rodrigo
    Objetivos: La administración de analgesia para el parto es una obligación legal en Chile. Este trabajo describe la percepción de los profesionales involucrados en la atención de las pacientes que están en trabajo de parto, con relación a la implantación del uso de la técnica de analgesia controlada por la paciente en cuanto a los resultados obstétricos obtenidos, satisfacción de los profesionales, impacto en la carga de trabajo y seguridad. Material y métodos: Se aplicó una encuesta autoadministrada a todos los profesionales que trabajan en el área de partos de la institución y se revisaron las incidencias de los resultados obstétricos y de carga de trabajo. La encuesta incluyó 25 preguntas estructuradas utilizando una escala tipo Lickert evaluando las dimensiones de calidad analgésica, carga y forma de trabajo en el Servicio, efectos colaterales, satisfacción de paciente y personal. Concluía la encuesta con una pregunta de percepción global. Resultados: La percepción global de satisfacción tras la introducción de la técnica para trabajo de parto fue de 6,0 (±0,88). En el grupo de anestesiólogos se evidencia una reducción de la carga laboral, sin afectar el resultado obstétrico ni neonatal. Conclusión: Considerando las limitaciones del tipo de trabajo, de no conocer el impacto económico ni la satisfacción de las pacientes en las cuales se utiliza la técnica de analgesia epidural, recomendamos la utilización de la analgesia controlada por la paciente para esta indicación, dada la buena percepción del equipo de trabajo con relación a los resultados obstétricos, la satisfacción con la técnica y la disminución en la carga de trabajo.

    Simulación en Anestesiología
    (2013) Clede-Belforti, L.; Nazar Jara, Claudio; Montaña Rodríguez, Rodrigo; Corvetto Aqueveque, Marcia Antonia
    Training in anaesthesia relies on the duration and quality of clinical experience. It involves exposure to a range of interventions. This works well in routine cases, but when an uncommon and life-threatening event occurs, the anaesthetist needs to carry out multiple tasks simultaneously. Aviation has remarkable similarities with the practice of anaesthesia. Over the years, the aviation industry has used simulation to train and assess individuals very effectively. Anaesthetists face rapidly evolving clinical situations. This needs appropriate decision-making and communication with others in the theatre team. Simulation, using current technology, offers innovative and reproducible training experience. It enables standardised scenario building and reflective learning. Various non-technical aspects of an anaesthetist's day-to-day work could also be addressed to during such training. The technology could be used very effectively for the assessment of competence too. Simulation has been used for technology development and appraisal over the years.
