Safety and side effects of propofol in clinical practice - literature overview

open access: yesJournal of Education, Health and Sport, 2023
Introduction and purpose Since people have been conducting surgeries to improve their health, they have always faced the problem of pain that these actions inevitably bring. Propofol as an anesetic is one of the solutions to these problems. Due to the

Propofol Induction Reduces the Capacity for Neural Information Integration: Implications for the Mechanism of Consciousness and General Anesthesia [PDF]

open access: yes, 2008
The cognitive unbinding paradigm suggests that the synthesis of cognitive information is attenuated by general anesthesia. Here, we investigated the functional organization of brain activities in the conscious and anesthetized states, based on ...

Macaque's Cortical Functional Connectivity Dynamics at the Onset of Propofol-Induced Anesthesia [PDF]

open access: yesarXiv, 2021
Propofol, when administered for general anesthesia, induces oscillatory dynamic brain states that are thought to underlie the drug's pharmacological effects. Despite the elucidation of propofol's mechanisms of action at the molecular level, its effects on neural circuits and overall cortical functioning, which eventually lead to unconsciousness, are ...

Towards Real-World Applications of Personalized Anesthesia Using Policy Constraint Q Learning for Propofol Infusion Control [PDF]

open access: yes, 2023
Automated anesthesia promises to enable more precise and personalized anesthetic administration and free anesthesiologists from repetitive tasks, allowing them to focus on the most critical aspects of a patient's surgical care. Current research has typically focused on creating simulated environments from which agents can learn.

Comparison of the qCON and qNOX indices for the assessment of unconsciousness level and noxious stimulation response during surgery [PDF]

open access: yes, 2016
The objective of this work is to compare the performances of two electroencephalogram based indices for detecting loss of consciousness and loss of response to nociceptive stimulation.

Increasing Robustness of the Anesthesia Process from Difference Patient's Delay Using a State-Space Model Predictive Controller [PDF]

open access: yesProcedia Engineering 15 (2011) 928-932, 2013
The process of anesthesia is nonlinear with time delay and also there are some constraints which have to be considered in calculating administrative drug dosage. We present an Extended Kalman Filter (EKF) observer to estimate drug concentration in the patient's body and use this estimation in a state-space based Model of Predictive Controller (MPC) for

Incidence of tolerance in children undergoing repeated administration of propofol for proton radiation therapy: a retrospective study

open access: yesBMC Anesthesiology, 2018
Background Propofol is an excellent hypnotic drug for use in repeated radiation procedures in young children. To date, tolerance to propofol generally does not develop in pediatric patients undergoing radiation therapy.

On the role of the corpus callosum in interhemispheric functional connectivity in humans [PDF]

open access: yes, 2017
Resting state functional connectivity is defined in terms of temporal correlations between physiologic signals, most commonly studied using functional magnetic resonance imaging. Major features of functional connectivity correspond to structural (axonal)

Effects of propofol in lipid-based emulsion and in microemulsion on the incidence of endothelial lesion in rabbits [PDF]

open access: yesActa Cirúrgica Brasileira, 2013
PURPOSE: To compare the incidence of endothelial injury after single-dose or continuous propofol infusion in conventional lipid-based emulsion (LE) versus microemulsion (ME).

The Impact of Age on Propofol Requirement for Inducing Loss of Consciousness in Elderly Surgical Patients

open access: yesFrontiers in Pharmacology, 2022
It is generally accepted that geriatric patients are more sensitive to propofol than adults; thus, a dose-adjusted propofol is recommended for these patients during the induction of anesthesia.
