This study aimed to investigate the risk factors of intraoperative anesthesia adverse events (IAAEs) in children with laryngeal diseases. ⋯ The severe airway obstruction increases the risk of SpO2 decline and HR decline as well as the possibility of perioperative emergency orotracheal intubation and remaining intubated postoperatively, whereas supraglottic surgery and surgery performed under endotracheal intubation reduce the incidence rates of these IAAEs in children with laryngeal diseases.

Randomized Controlled Trial
A comparison of the effectiveness of the streamlined liner of pharyngeal airway in paralyzed and nonparalyzed patients undergoing gynecological surgery: a randomized trial.
To compare the effectiveness of streamlined liner of pharyngeal airway (SLIPA) in paralyzed and nonparalyzed, anesthetized patients undergoing gynecological surgery. ⋯ SLIPA had good performance in both paralyzed and nonparalyzed patients. There was no difference in SLIPA performance or complications irrespective of muscle relaxant use, except decrease in PIP and prolong recovery time in paralyzed patients.

Randomized Controlled Trial Comparative Study
Comparing the efficacy and safety between propofol and dexmedetomidine for sedation in claustrophobic adults undergoing magnetic resonance imaging (PADAM trial).
To determine the efficacy of sedation with dexmedetomidine compared to propofol for claustrophobic adults undergoing magnetic resonance imaging (MRI) in our institution. ⋯ Both dexmedetomidine and propofol can effectively reduce anxiety levels of claustrophobic adults undergoing MRI, but dexmedetomidine takes longer to achieve adequate anxiolysis and sleep and may have an effect on image quality. Hypotension and bradycardia are common adverse effects observed with dexmedetomidine.

Randomized Controlled Trial
The optimal combination of mechanical ventilator parameters under general anesthesia in obese patients undergoing laparoscopic surgery.
Pulmonary dysfunction after laparoscopic surgery is commonly seen in the high-risk group of obese patients. To reduce or avoid this complication caused by an improper combination of mechanical ventilation parameters, we conducted the following trial of 3 factors with 3 levels of mechanical ventilation, aimed to obtain the low airway pressure with good ventilator effects. ⋯ The best combination of respiratory parameters is A3B1C2, that is, f=9beats per minute, VT=8mL/kg, and I:E=1:2.0. That is, neither small tidal volume and faster frequency nor slow frequency large tidal volume is a good choice. To let obese patients under general anesthesia can obtain a lung protective effect of low airway pressure with good ventilation; it is noteworthy that (1) I:E of airway pressure (PIP, Pmean) is the important impact factor for the protection of the lung and (2) I:E of airway pressure (PIP, Pmean) is the factor with opposite properties.
