Synchrony patterns between the EEG measured from the subthalamic nucleus and scalp are analyzed during induction of propofol anesthesia. Various methods such as Coherence, Phase Locking Value, Partial Directed Coherence, Mutual Information, and Transfer Entropy are applied. The results indicate that, in general, the synchrony patterns seen in the depth-scalp electrode pair are similar to those seen between two scalp electrodes of opposite hemispheres. A clear change of state is revealed at about 10 minutes before burst suppression; this event is revealed by linear (Coherence) as well as nonlinear (Phase Locking Value) and information theoretic (Mutual Information and Transfer Entropy) measures. The results suggest that relatively large depth electrodes such as those used in the treatment of the Parkinson's disease are predominantly sensitive to cortical activity.

Assessing the use of the Index of Consciousness (IoC) as a monitoring tool for the sedative effects of ciprofol during general anesthesia induction: a prospective observational study.
Perioper Med (Lond)
January 2025
Department of Anesthesia, Characteristic Medical Center of Chinese People's Armed Police Force (PAP), Tianjin, China.
Background: We investigated the consistency and accuracy of the Index of Consciousness (IoC) and the Bispectral Index (BIS) in monitoring the sedative effect of ciprofol during the induction of general anesthesia. There is extensive literature that reports good consistency and correlations between the IoC1 and the BIS in reflecting the sedation levels induced by propofol and sevoflurane but not by ciprofol.
Objective: The aim was to compare the consistency and accuracy of the IoC and BIS in monitoring the sedative effect of ciprofol during the induction of general anesthesia.
Comparison of Remimazolam-Flumazenil and Propofol on Psychomotor Function and Emergence Following General Anesthesia in Surgical Abortion: A Randomized Controlled Trial.
Drug Des Devel Ther

Department of Anesthesiology, Ningbo No. 2 hospital, Ningbo, 315010, People's Republic of China.
Objective: This study aims to compare the recovery profiles of remimazolam combined with flumazenil against those of propofol in patients undergoing painless surgical abortion, focusing on psychomotor function and emergence. Rapid recovery and restoration of psychomotor function are critical for enhancing patient safety and satisfaction in outpatient procedures like surgical abortion.
Methods: A total of 110 patients scheduled for surgical abortion were randomly assigned to either the remimazolam group (Group R) or the propofol group (Group P) in a 1:1 ratio.
Hypotension after induction of anesthesia with remimazolam or etomidate: a non-inferiority randomized controlled trial in patients undergoing coronary artery bypass grafting.

Department of Anaesthesiology and Pain Medicine, Samsung Medical Centre, Sungkyukwan University School of Medicine, Seoul, Republic of Korea.
Background: Remimazolam is a novel ultra-short-acting benzodiazepine known for its hemodynamic stability over propofol. However, its hemodynamic effects compared to those of etomidate are not well established. This study aimed to determine whether the use of remimazolam is non-inferior to etomidate with regard to the occurrence of post-induction hypotension in patients undergoing coronary arterial bypass grafting.

Background: Using neuromuscular blocking agents (NMBA) in pediatric induction protocol is a challenging matter. Therefore, in this study, we aimed to find a safer way for anesthesia in children. We compared the effects of dexmedetomidine with atracurium on intubation conditions in children aged 6-12 years under general anesthesia.

Purpose: Propofol, a widely utilized anesthetic, is employed to alleviate pain and anxiety in outpatient oocyte retrieval procedures. However, its potential impact and safety profile in the context of fertilization and embryo transfer (IVF-ET) remain unclear.
Methods: This retrospective study enrolled 1187 patients undergoing IVF-ET, and divided into two groups depending on whether they received propofol (propofol group, n=140) or not (control group, n=1047) for anesthesia during oocyte retrieval.
