    Performance of the cerebral state index during increasing levels of propofol anesthesia: A comparison with the bispectral index
    (LIPPINCOTT WILLIAMS & WILKINS, 2007) Cortinez, Luis I.; Delfino, Alejandro E.; Fuentes, Ricardo; Munoz, Hernan R.
    BACKGROUND: The cerebral state monitor is a new device to measure depth of anesthesia. In this study we compared the cerebral state monitor with the bispectral index (BIS) monitor during propofol anesthesia.

    Pharmacokinetics of levobupivacaine (2.5 mg/kg) after caudal administration in children younger than 3 years
    (LIPPINCOTT WILLIAMS & WILKINS, 2008) Cortinez, Luis I.; Fuentes, Ricardo; Solari, Sandra; Ostermann, Paola; Vega, Miguel; Munoz, Hernan R.
    BACKGROUND: Caudal administration of levobupivacaine (2.5 mg/kg) in children is used frequently in some hospitals. However, no reports of levobupivacaine concentrations have been published with this dosing scheme. We report the results of a study on the pharmacokinetics of levobupivacaine (2.5 mg/kg) after caudal administration in children younger than 3 yr.

    Process-oriented instrument and taxonomy for teaching surgical procedures in medical training: The ultrasound-guided insertion of central venous catheter

    Procedural 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.

    The Dynamic Relationship Between End-Tidal Sevoflurane Concentrations, Bispectral Index, and Cerebral State Index in Children
    (LIPPINCOTT WILLIAMS & WILKINS, 2008) Fuentes, Ricardo; Cortinez, Luis I.; Struys, Michel M. R. F.; Delfino, Alejandro; Munoz, Hernan
    BACKGROUND: To guide anesthetic administration with electroencephalogram monitors in children, an adequate characterization of the anesthetic effect measured by these monitors in this population is needed. We sought to quantify and compare the dynamic profile of sevoflurane's effect measured with the cerebral state index (CST) and the bispectral index (BIS) in children.

    The Influence of Age on the Dynamic Relationship Between End-Tidal Sevoflurane Concentrations and Bispectral Index
    (LIPPINCOTT WILLIAMS & WILKINS, 2008) Cortinez, Luis I.; Troconiz, Inaki F.; Fuentes, Ricardo; Gambus, Pedro; Hsu, Yung Wei; Altermatt, Fernando; Munoz, Hernan R.
    BACKGROUND: Age is an important determinant of the pharmacokinetic profile of inhaled anesthetics. The influence of age on the dynamic profile of sevoflurane's effect has not been well described. We performed this study to characterize the influence of age and other covariates on the dynamic relationship between sevoflurane end-tidal concentration (C-ET) and its effect measured by bispectral index (BIS).

    Understanding Undesired Procedural Behavior in Surgical Training: The Instructor Perspective
    (SPRINGER INTERNATIONAL PUBLISHING AG, 2019) Galvez, Victor; Meneses, Cesar; Fagalde, Gonzalo; Munoz Gama, Jorge; Sepulveda, Marcos; Fuentes, Ricardo; de la Fuente, Rene; DiFrancescomarino, C; Dijkman, R; Zdun, U
    In recent years, a new approach to incorporate the process perspective in the surgical procedural training through Process Mining has been proposed. In this approach, training executions are recorded, to later generate end-to-end process models for the students, describing their execution. Although those end-to-end models are useful for the students, they do not fully capture the needs of the instructors of the training programs. This article proposes a taxonomy of activities for surgical process models, analyzes the specific questions instructors have about the student execution and their undesired procedural behavior, and proposes the Procedural Behavior Instrument, an instrument to answer them in an easy-to-interpret way. A real case was used to test the approach, and a preliminary validity was developed by a medical expert.
