Objective: Interventional bronchoscopy procedures are novel and effective modes of diagnosing and treating airway lesions. Airway management and ventilation are a major concern, especially when considering the fire hazard of ventilating during endobronchial thermal therapies. The aim of this study was to evaluate the usage of laryngeal mask airway (LMA) compared to rigid bronchoscopy for the ventilation of patients undergoing diagnostic or therapeutic interventional bronchoscopy procedures.
Methods: During this prospective randomised clinical trial study, patients were randomly allocated to two groups for ventilation: LMA and rigid bronchoscopy. Vital signs, including blood pressure, heart rate and percentage of blood O2 saturation before and during the procedure, degree of sore throat after recovery and physician's satisfaction, were recorded.
Results: A total of 83 patients, including 45 in the "LMA" and 38 in the "rigid" groups, were enrolled in this study. Their mean age was 51±17 years, and 59 (71%) were male. There was a statically significant difference between "rigid" and "LMA" categories regarding the decrease in O2 during the procedure in proportion to baseline figures (p=0.028). Haemodynamic parameters were better maintained using LMA compared to rigid bronchoscopy.
Conclusion: Laryngeal mask ventilation maintains better oxygenation and haemodynamic stability and ensures physicians' and patients' satisfaction regarding ease of use, airway access and fewer complications compared to rigid bronchoscopy. Therefore, LMA can be introduced as a reliable alternative for ventilation during interventional airway procedures.

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.

Introduction: We determined the median effective dose and 95% confidence interval (CI) of remimazolam required to inhibit laryngeal mask airway (LMA) insertion reactions combined with sufentanil 0.3 μg/kg in pediatric anesthesia.
Methods: Children scheduled to undergo elective laryngeal mask anesthesia were divided into the preschool (age: 3-6 years) and school-age (6-12 years) groups.

Objective: To investigate the efficacy of the SaCo videolaryngeal mask airway (VLMA) in combination with a bronchial blocker in patients undergoing minimally invasive thoracoscopic surgery.
Methods: A retrospective analysis was conducted on the clinical data of 120 patients who underwent minimally invasive thoracoscopic surgery from January 2022 to December 2023. Patients were grouped based on their treatment methods: 68 patients who received the SaCo VLMA combined with a bronchial blocker intraoperatively were designated as the L group, while 52 patients who received a tracheal tube combined with a bronchial blocker intraoperatively were designated as the E group.

Background: The use of laryngeal masks (LM) has increased widely today, both in anesthesia and in emergency cases. LM are available as reusable and disposable. Although reuse of disposable LM is not recommended, they are reused again after decontamination with different methods in anesthesia units in some countries.
