We report severe hypotension after induction of general anesthesia in a patient receiving an angiotensin II receptor antagonist and an alpha-blocker. A 50-year-old man with diabetes mellitus who had been treated with candesartan cilexetil and doxazosin was scheduled for vitreous surgery. He was operated on for vitreous surgery three times. He developed severe hypotension after induction of anesthesia with propofol and fentanyl on two occasions, when he was taking candesartan cilexetil and doxazosin. Repeated injections of intravenous ephedrine could not raise the blood pressure. After discontinuation of both drugs, although he developed hypotension after induction of anesthesia with propofol and fentanyl, hypotension was mild and responded promptly to intravenous ephedrine.

Introduction: Propofol is a fast-acting intravenous anaesthetic widely used for sedation and anaesthesia in gastrointestinal endoscopy, bronchoscopy, and the induction/maintenance of general anaesthesia in outpatients and inpatients; however, propofol has several undesirable effects, including injection pain, which affects the physical and mental health of patients, and cardiopulmonary depression, characterised by hypotension, bradycardia and apnea, which commonly occur in clinical practice. Ciprofol (HSK3486) is a propofol analogue with good clinical safety, high potency and some advantages over propofol, including lower injection pain and haemodynamic depression in patients undergoing gastroscopy and colonoscopy. This study aims to compare the impact of equivalent effective doses of propofol and ciprofol on haemodynamic changes in patients undergoing bronchoscopy under general anaesthesia.

Purpose: The incidence of hemodynamic instability associated with dexmedetomidine (DEX) sedation has been reported to exceed 50%, with substantial inter-individual variability in response. Genetic factors have been suggested to contribute significantly to such variation. The aim of this study was to identify the clinical, pharmacokinetic, and genetic factors associated with DEX-induced hemodynamic instability in pediatric anesthesia patients.

Background: To evaluate the safety and efficacy of different doses of ciprofol for the induction of general anesthesia in elderly patients with diabetes undergoing spinal surgery.
Methods: Ninety elderly diabetic patients scheduled for elective single-level posterior lumbar interbody fusion (PLIF) under general anesthesia were enrolled and randomly assigned to three groups according to the induction dose of ciprofol: group A (0.2 mg/kg), Group B (0.
