: This study investigated the effects of propofol and isoflurane on endoplasmic reticulum (ER) stress in an animal model under general anaesthesia. : Rats were randomly divided into Propofol and Isoflurane groups. Anaesthesia was maintained with propofol for Propofol group or isoflurane for Isoflurane group during 3 h. ER stress from lymphocytes in blood and tissues was evaluated between two groups after euthanasia. Reactive oxygen species (ROS) from lymphocytes in blood and tissues, and cytokines in blood were also checked. An immunohistochemical assay for ER stress marker from tissues was performed. : After anaesthesia, the levels of CCAAT-enhancer-binding protein homologous proteins (CHOP) in blood and liver were significantly higher in Isoflurane group, compared to Propofol group [blood, 31,499 ± 4,934 (30,733, 26,441-38,807) mean fluorescence intensity (MFI) in Isoflurane group 20,595 ± 1,838 (20,780, 18,866-22,232) MFI in Propofol group, = 0.002; liver, 28,342 ± 5,535 (29,421, 23,388-32,756) MFI in Isoflurane group 20,004 ± 2,155 (19,244, 18,197-22,191) MFI in Propofol group, = 0.020]. ROS in blood was significantly higher in Isoflurane group, compared to Propofol group. However, cytokines in blood and immunohistochemical assays in tissues were similar between groups. : Significant higher of ER stress from blood and liver were observed in rats under anaesthesia with isoflurane, compared to those that received propofol. ROS from blood also showed significant higher under anaesthesia with isoflurane. However, these findings were not associated with any changes in cytokines in blood or immunohistochemical assay in tissues.

Objective: This study aims to compare the effects of sevoflurane (SEV) and propofol (PRO) on postoperative cognitive dysfunction (POCD) in patients undergoing cardiac surgery (CS) under cardiopulmonary bypass (CPB), with a focus on evaluating the efficacy of these anesthetic agents in preventing POCD.
Methods: A total of 113 patients undergoing CS with CPB were grouped into two: PRO group (n = 58) and SEV group (n = 55). Baseline data, anesthesia effects (CPB duration, anesthesia time, respiratory recovery time, and anesthesia recovery time), Montreal Cognitive Assessment (MoCA) scores, POCD incidence, neurological function markers (NSE, S-100β, MMP9), and serum inflammatory markers (IL-6, IL-8, TNF-α) were analyzed.

Background: Ciprofol, a novel intravenous anesthetic derived from propofol, exhibits high lipophilicity. Its pharmacokinetics and pharmacodynamics may vary across different body mass indices (BMI) categories, but data on its optimal dosing as well as its safety and efficacy during colonoscopy anesthesia in varying BMI groups are lacking.
Objective: To evaluate the efficacy and safety of ciprofol during anesthesia for painless colonoscopy in patients with varying BMI, and to explore the correlation between BMI and induction dose.

Background: The peri-operative period may create a biological environment conducive to cancer cell survival and dissemination. Microscopic residual tumours (micrometastases) can be dislodged even with excellent surgical technique. At the same time, the stress response from surgery can temporarily impair immune function and activate inflammatory processes, increasing the risk of tumour proliferation.

Background: Propofol is one of the most used intravenous anesthetic agents in traumatic brain injury (TBI) patients undergoing emergency neurosurgical procedures. Despite being efficacious, its administration is associated with dose-related adverse effects. The use of adjuvants along with propofol aids in limiting its consumption, thereby mitigating the side effects related to propofol usage.

Background: While evidence from preclinical and observational cohort studies have suggested potential disparities in tumour behaviour associated with the choice of intra-operative anaesthetics, clinical evidence of tumour recurrence and metastasis remains inconclusive. We aimed to compare the impact of intra-operative anaesthesia on oncologic outcomes following hepatectomy for hepatocellular carcinoma.
Methods: Adult patients scheduled for elective hepatectomy for hepatocellular carcinoma were assigned randomly (1:1) to either propofol-based total intravenous anaesthesia or sevoflurane-based inhalational anaesthesia.
