Abstract
Background Postoperative sore throat (POST) is a common, undesirable result of endotracheal intubation during general anaesthesia. This study aimed to evaluate the effectiveness of benzydamine hydrochloride (BH) spray in reducing the incidence of POST in paediatric patients. Methods This randomized, double-blind, prospective study included 142 children 6–12 years of age, who were randomly assigned to receive either BH spray or control. After induction of anaesthesia, direct laryngoscope was placed and BH spray was applied to the upper trachea and vocal cord in the BH group and intubation was performed using a cuffed tube lubricated with normal saline. Intubation in the control group was performed using a cuffed tube lubricated with normal saline without any intervention. The balloon was inflated to a pressure of 20 cmH2O. Patients were extubated after fully awakened and transferred to the post-anaesthetic care unit (PACU), where they were examined for the presence of POST and any adverse events 30 min after arrival to the PACU. Postoperative pain was evaluated using a smartphone application. Results Seventy-one patients were allocated to each group. The incidence of POST in the BH group did not differ from that in the control group (control: BH = 35 (49.3%): 42 (59.2%); P = 0.238); postoperative pain was also similar between the groups. Other complications, such as breath holding, secretions, coughing, laryngospasm and desaturation events, did not differ between the groups. Conclusions Application of prophylactic BH spray to the vocal cords and upper trachea was not proven to reduce POST in paediatric patients. Trial registry NCT03074968 (ClinicalTrials.gov, Feb 26, 2017).

Abstract
Objectives A failed first attempt at laryngeal mask airway (LMA) insertion could increase the risk of laryngospasm, hypoxemia, and postoperative sore throat. This study was performed to investigate the risk factors for failed first-attempt LMA placement. Methods In total, 461 patients who underwent general anesthesia with a Supreme LMA (Teleflex Medical, Shanghai, China) and who had an American Society of Anesthesiologists (ASA) physical status of I to III were prospectively enrolled. The LMA was inserted after anesthetic induction. We recorded the insertion conditions and each patient’s age, ASA status, body weight, body mass index (BMI), duration of anesthesia, size of LMA, and cuff pressure; the years of work experience of the anesthesiologists; and the use or nonuse of lidocaine gel as a lubricant. Results Successful first-attempt placement of the Supreme LMA was achieved in 438 (95.10%) patients, while first-attempt placement failed in 23 (4.99%). Significant risk factors for failure of first-attempt LMA insertion included high age, high body weight, BMI of <20 kg/m2, and insertion without using lidocaine gel. Conclusions A patient age of >61 years, high body weight, BMI of <20 kg/m2, and insertion without lidocaine gel could significantly increase the risk of failed first-attempt Supreme LMA insertion.
