RESUMO

BACKGROUND: We hypothesized that the time to successful fibreoptic tracheal intubation through the nasal route would be faster than the oral route for both experts and trainees in children <2 yr of age. METHODS: One hundred children, 24 months and under in age, were randomized to an operator (expert or trainee), and route (nasal or oral) for fibreoptic tracheal intubation. Three separate times were then measured: (i) time to first glottic view, (ii) time to carinal view, and (iii) total time to successful tracheal intubation. The number of attempts made, manoeuvres needed to obtain an adequate laryngeal view, and manoeuvres for tracheal tube passage were also recorded. RESULTS: Time to successful tracheal intubation was significantly faster for experts than trainees. There was no difference in the time to tracheal intubation between the nasal and oral routes for experts. In trainees, intubation times were shorter for the nasal route-median (inter-quartile range) time (s) to carinal view was 35 (27-63) for the nasal route vs 59 (38-94) for the oral route (P=0.03), and the median time to successful tracheal intubation were 62 (49-122) vs 117 (61-224), P=0.05, for the nasal and oral routes, respectively. For trainees, the oral route required a greater number of airway manoeuvres for adequate laryngeal views and passage of the tracheal tube compared with the nasal route. CONCLUSIONS: For clinicians with less experience in using paediatric bronchoscopes, fibreoptic tracheal intubation through the nasal route may be a more straightforward process than the oral route in children <2 yr of age.

RESUMO

BACKGROUND: Supraglottic airways (SGAs) have an established role in airway management of difficult airways in both adults and children. However, there are limited data regarding the use of SGAs for primary airway management in children. The aim of this study is to assess the success rates and adverse events related to the use of SGAs for primary airway management during anaesthesia in children with difficult airways. METHODS: A retrospective analysis of SGA use for primary airway management in the difficult airway population in a single centre over a 4-yr period was performed. Difficult airway was defined as either a history of difficult direct laryngoscopy (a documented Cormack and Lehane Grade 3 or greater and the need for an alternate device to direct laryngoscopy for successful tracheal intubation), a history of difficult mask ventilation, or both. The difficult airway condition, patient characteristic data, type and length of procedure, type and size of SGA placed, number of attempts for successful device placement, success/failure associated with the device during anaesthetic maintenance, and complications were recorded. RESULTS: A total of 77,272 children received general anaesthesia in a free-standing paediatric institution. Four hundred and fifty-nine patients were reported to have a difficult airway. Of those, 109 received general anaesthesia and an SGA for primary management, meeting the inclusion criteria for this study during a 4-yr period. An SGA was successfully used in 96% of these patients. In four patients, an alternative airway was needed. CONCLUSIONS: SGAs can be effectively utilized for airway maintenance in the paediatric difficult airway population.

RESUMO

We prospectively compared free-handed and air-Q™ assisted fibreoptic-guided tracheal intubation in children < 2 years of age. Eighty healthy children were enrolled and randomly assigned to a technique (free-handed or air-Q assisted) and operator (trainee or attending). Time, number of attempts and manoeuvres required were assessed. There was no difference in median (IQR [range]) time to successful tracheal intubation between the free-handed (52.2 (34.8-67.7 [19.7-108.0]) s), and the air-Q assisted (60.3 (45.5-75.1 [28.1-129.0]) s; p = 0.13) groups, or the number of attempts needed. The air-Q assisted group required fewer manoeuvres to optimise the laryngeal view (median (IQR [range]) 0 (0-1 [0-2])) than the free-handed group (1 (1-1 [0-3]); p < 0.001). In conclusion, fibreoptic-guided tracheal intubation times were similar with and without the use of the air-Q, but supraglottic airway devices may be a consideration for their other practical advantages.
