Clinical outcomes of remote ischemic preconditioning prior to cardiac surgery: A meta‐analysis of randomized controlled trials [PDF]

open access: yes, 2017
Background Multiple randomized controlled trials of remote ischemic preconditioning ( RIPC ) prior to cardiac surgery have failed to demonstrate clinical benefit. The aim of this updated

A Transformer-based Prediction Method for Depth of Anesthesia During Target-controlled Infusion of Propofol and Remifentanil [PDF]

open access: yesarXiv, 2023
Accurately predicting anesthetic effects is essential for target-controlled infusion systems. The traditional (PK-PD) models for Bispectral index (BIS) prediction require manual selection of model parameters, which can be challenging in clinical settings. Recently proposed deep learning methods can only capture general trends and may not predict abrupt

Unconsciousness reconfigures modular brain network dynamics [PDF]

open access: yes, 2020
The dynamic core hypothesis posits that consciousness is correlated with simultaneously integrated and differentiated assemblies of transiently synchronized brain regions. We represented time-dependent functional interactions using dynamic brain networks, and assessed the integrityof the dynamic core by means of the flexibility and largest multilayer ...

Propofol inhibits proliferation and epithelial-mesenchymal transition of MCF-7 cells by suppressing miR-21 expression

open access: yesArtificial Cells, Nanomedicine, and Biotechnology, 2019
Breast cancer is a common malignant tumor with a high incidence of recurrence and metastasis. It has been reported that propofol has certain anti-breast cancer effects, but the intrinsic molecular mechanism remains unclear.

The Effect of Sevoflurane Plus Propofol on Pain and Complications after Laminectomy: A Randomized Double Blind Clinical Trial [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2017
Introduction: Pain is one of the most important reasons for the patients concern after surgery. The perfect sedative should have properties like rapid onset, least pain and adverse effects.

Early phase pharmacokinetics but not pharmacodynamics are influenced by propofol infusion rate [PDF]

open access: yes, 2009
Background: Conventional compartmental pharmacokinetic models wrongly assume instantaneous drug mixing in the central compartment, resulting in a flawed prediction of drug disposition for the first minutes, and the flaw affects pharmacodynamic modeling ...

Depth of anesthesia control using internal model control techniques [PDF]

open access: yes, 2010
The major difficulty in the design of closed-loop control during anaesthesia is the inherent patient variability due to differences in demographic and drug tolerance.

Prediction of Individual Propofol Requirements based on Preoperative EEG Signals [PDF]

open access: yesarXiv, 2020
The patient must be given an adequate amount of propofol for safe surgery since overcapacity and low capacity cause accidents. However, the sensitivity of propofol varies from patient to patient, making it very difficult to determine the propofol requirements for anesthesia.

The influence of storage time and temperature on propofol concentrations in canine blood and plasma [PDF]

open access: yesPeerJ, 2017
Propofol is an intravenous anesthetic commonly used due to its favorable pharmacokinetic and pharmacodynamic profile. There are discrepancies in the literature about the most appropriate sample for determining propofol concentrations. Although plasma has

SIRT3 Enhances the Protective Role of Propofol in Postoperative Cognitive Dysfunction via Activating Autophagy Mediated by AMPK/mTOR Pathway

open access: yesFrontiers in Bioscience-Landmark, 2022
Background: Postoperative cognitive dysfunction (POCD) is a common complication after surgery and anesthesia. In this study, we aimed to determine the neuroprotective mechanism of Sirtuin 3 (SIRT3) and propofol in POCD. Methods: The cognitive dysfunction
