The laryngeal mask airway (LMA), developed in 1983, is a new device to assist in the management of the pediatric and adult airway. In 1991, the Food and Drug Administration gave its approval for use of the LMA in the United States. The LMA is reusable and appears to provide cost-effective airway management in numerous situations. The LMA is simple to use, atraumatic to insert, and helpful in overcoming an obstructed airway. Its role in management of the difficult airway and the traumatic airway is still evolving. This review will introduce the LMA to the nonanesthesiologist and review for the anesthesiologist the origins of the LMA, its physical structure, the technical aspects of insertion, problems with aspiration, its role in the difficult airway, and experience with the pediatric population.

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.
