“…Safety and management recommendations for venous lines in TIVA include sound alarms from infusion pumps to detect pressure changes, active surveillance of venous lines, and use of antireflux valves (Barvais et al, 2013). Time of extubation, considered as the time elapsed between the suspension of the infusions of propofol and remifentanil and the extubation of the patient, was 8 (Mcgee et al, 2006;Gómez Oquendo et al, 2013;Hemmerling & Charabati, 2010;Purdon et al, 2015; Need for vasopressors** 1 (2%) 6 (22.2%) 0 (0) 7 (7.4%)…”

“…The authors developed a closed loop system using software based on fuzzy logic, proven in a case report (Gómez Oquendo et al, 2013), a prospective case series (Hemmerling et al, 2013a) and a controlled clinical trial (Casas & Fernandez, 2016), which provided clinically adequate anesthesia and satisfactory operating conditions in all studied patients during the period of automatic control using the BIS TM for anesthetic depth monitoring.…”

Introduction: Closed loop total intravenous anesthesia is a technique in which the patient's hemodynamic and anesthetic depth variables are monitored, and based on this information, a computer controls the infusion rate of drugs to keep them within pre-established clinical parameters. Objective: To describe the technical and clinical performance of a closed loop system for total intravenous anesthesia with propofol and remifentanil, using the SEDLine TM monitor Design: Multicentric prospective cohort study Setting: Surgery room Patients: ASA I-II undergoing elective surgery Measurements: The authors designed a closed loop system that implements a control algorithm based on anesthetic depth monitoring and the Patient State Index (PSI TM ) of the SEDLine monitor for propofol, and on hemodynamic variables for remifentanil. The measurement of clinical performance was made based on the percentage of PSI TM maintenance time in the range 20-50. Precision analysis was evaluated by measuring median performance error (MDPE) can be defined as the median difference between actual and desired values, which refers to the degree of precision in which the controller is able to maintain the control variable within the objective set by the anesthesiologist; it represents the direction (over-prediction or underprediction) of performance error (PE) rather than size of errors, which is represented by MDAPE, median absolute percentage error, Wobble index, which is used for measuring the intrasubject variability in performance error. Results: Data were obtained from 93 patients in three healthcare centers. The percentage of PSI TM maintenance time in the 20-50 range was 92% (80.7-97.0). MDPE was 10.7 (− 11.0-18.0), MDAPE 21.0 (14.2-26.8) and wobble 10.7 (7.0-16.9). No adverse surgical or anesthetic events were found.

“…La tecnología computacional ha facilitado la incorporación de los modelos teóricos para la simulación farmacocinética de fármacos como propofol (modelo de Schnider) 4 y remifentanil (modelo de Minto) 5 . Estos sistemas permiten controlar las infusiones ajustándolas a determinadas concentraciones objetivo del fármaco deseado [6][7][8][9] . Esta tecnología se conoce en la actualidad como target control infusión (infusión controlada por objetivo, por sus siglas en inglés como TCI) y ha facilitado la administración de fármacos intravenosos como el remifentanil y propofol, permitiendo una rápida titulación para alcanzar distintos objetivos terapéuticos con mayor estabilidad hemodinámica 3,10 .…”
