BACKGROUND: The indirect visualisation of the glottic area with a videolaryngoscope could improve intubation conditions which may possibly lead to a higher success rate of the first intubation attempt. OBJECTIVE: Comparison of videolaryngoscopy and direct laryngoscopy for elective airway management in paediatric patients. DESIGN: Prospective randomised controlled trial. SETTINGS: Operating room. PARTICIPANTS: 535 paediatric patients undergoing elective anaesthesia with tracheal intubation. 501 patients were included in the final analysis. INTERVENTIONS: Patients were randomly allocated to the videolaryngoscopy group (n = 265) and to the direct laryngoscopy group (n = 269) for the primary airway management. MAIN OUTCOME MEASURES: The first attempt intubation success rate was assessed as the primary outcome. The secondary outcomes were defined as: the time to successful intubation (time to the first EtCO2 wave), the overall intubation success rate, the number of intubation attempts, the incidence of complications, and the impact of the length of the operator's clinical practice. RESULTS: The study was terminated after the planned interim analysis for futility. There were no significant demographic differences between the two groups. The first attempt intubation success rate was lower in the videolaryngoscopy group; 86.8% (n = 211) vs. 92.6% (n = 239), P = 0.046. The mean time to the first EtCO2 wave was longer in the videolaryngoscopy group at 39.0 s ± 36.7 compared to the direct laryngoscopy group, 23.6 s ± 24.7 (P < 0.001). There was no difference in the overall intubation success rate, in the incidence of complications nor significant difference based on the length of the clinical practice of the operator. CONCLUSIONS: The first attempt intubation success rate was lower in the videolaryngoscopy group in comparison to the direct laryngoscopy group. The time needed for successful intubation with videolaryngoscopy was longer compared with direct laryngoscopy. TRIAL REGISTRATION: Clinicaltrials.gov identifier: NCT03747250.

BACKGROUND: The incidence of difficult airway in paediatric patients is lower than that the adult population, and the majority should be predictable. AIMS: The primary aim of this trial was to evaluate the incidence of difficult airway in pediatric patients. The secondary aim was to predict difficult airway in these patients. METHODS: Paediatric patients undergoing elective surgery under general anaesthesia in a tertiary university hospital were examined, and a panel of difficult airway prediction tests was performed. We recorded the incidence, risk factors for difficult airway and events associated with difficult airway together with the sensitivity and specificity of tests for difficult airway and events associated with difficult airway prediction. RESULTS: We prospectively included 389 paediatric patients. The incidence of difficult airway was 3.6%; the incidence of events associated with difficult airway was 10%. The sensitivity for prediction of events associated with difficult airway during the pre-anaesthesia evaluation was 5.3% with the specificity 93.3%. In the operating room, the sensitivity of prediction was 15% with 97.8% specificity. CONCLUSION: We found minimal efficacy for preanaesthesia difficult airway prediction.

BACKGROUND: Laryngeal mask UNIQUE® (LMAU) is supraglottic airway device with good clinical performance and low failure rate. Little is known about the ideal position of the LMAU on the magnetic resonance imaging (MRI) and whether radiological malposition can be associated with clinical performance (audible leak) in children. The primary aim of the study was to evaluate incidence of the radiologic malposition of the LMAU according to size. The secondary outcome was the clinical performance and associated complications (1st attempt success rate, audible leak) in LMAUs in correct position vs. radiologically misplaced LMAUs. METHODS: In prospective observational study, all paediatric patients undergoing MRI of the brain under general anaesthesia with the LMAU were included (1.9.2016-16.5.2017). The radiologically correct position: LMAU in hypopharynx, proximal cuff opposite to the C1 or C2 and distance A (proximal cuff end and aditus laryngis) ≤ distance B (distal cuff end and aditus laryngis). Malposition A: LMAU outside the hypopharynx. Malposition B: proximal cuff outside C1-C2. Malposition C: distance A ≥ distance B. We measured distances on the MRI image. Malposition incidence between LMAU sizes and first attempt success rate in trainees and consultant groups was compared using Fisher exact test, difference in incidence of malpositions using McNemar test and difference in leakage according to radiological position using two-sample binomial test. RESULTS: Overall 202 paediatric patients were included. The incidence of radiologically defined malposition was 26.2% (n = 53). Laryngeal mask was successfully inserted on the 1st attempt in 91.1% (n = 184) cases. Audible leak was detected in 3.5% (n = 7) patients. The radiologically defined malposition was present in 42.9% (n = 3) cases with audible leak. The rate of associated complications was 1.5% (n = 3): laryngospasm, desaturation, cough. In 4.0% (n = 8) the LMAU was soiled from blood. Higher incidence of radiological malposition was in LMAU 1.0, 1.5 and LMAU 3, 4 compared to LMAU 2 or LMAU 2.5 (p < 0.001). CONCLUSION: Malposition was not associated with impaired clinical performance (audible leak, complications) of the LMAU or the need for alternative airway management.
