This case report describes the perforation of a laryngeal mask during central venous cannulation of the internal jugular vein in a 2000 g, formerly preterm infant. The procedure was undertaken with the patient under general anaesthesia with a laryngeal mask and spontaneous breathing. As a result of the infant's clinical status, multiple needle insertions were required to obtain venous access. The needle was inadvertently advanced to the retropharynx and perforated the air-filled part of the laryngeal mask. Ventilation parameters remained stable. The laryngeal mask causes anatomical alterations of cervical structures in the newborn and therefore its use for the airway management during jugular vein cannulation appears to be limited.

Background: A previous study showed that airway ultrasound, specifically the distance from the skin to the hyoid bone (DSHB), may be correlated with a higher risk of difficult mask ventilation (DMV). However, the study was conducted in Italy and lacks data for the Asian and Thai populations. This study aimed to predict DMV using pre-operative ultrasonography to measure the DSHB and from the skin to the thyroid isthmus (DSTI) in Thai patients undergoing elective surgery under general anesthesia.

Background: Prospective trial evidence is lacking regarding the application of enhanced recovery after surgery (ERAS) in transvaginal pelvic floor reconstruction surgery among older patients. Our study aimed to investigate whether implementing the ERAS protocol could enhance post-operative recovery in this patient population.
Methods: Older patients undergoing elective transvaginal pelvic floor reconstruction surgery were randomly assigned to either the ERAS group or the conventional group.

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.
