Background And Aims:
In the cleft lip and palate, the laryngoscope blade often tends to lodge inside midline clefts, causing reduced manoeuvrability and tissue trauma. The paraglossal technique avoids the midline and offers better Cormack Lehane (CL) grades. We aimed to assess the first-pass intubation rate in performing the left paraglossal laryngoscopy with a curved-blade videolaryngoscope (VLS) versus direct laryngoscope (DLS) in children with cleft palate and evaluate the time taken for successful endotracheal intubation (TTI) and Intubation Difficulty Score (IDS) with both devices.
Methods:
This randomised controlled trial included 60 patients with cleft palate, between 3 months and 6 years. Patients were randomised into group V (VLS) (n = 30) and group D (DLS) (n = 30). Left paraglossal laryngoscopy was done with VLS or DLS, and the first-pass intubation, TTI, CL grade and IDS were recorded.
Results:
First-pass intubation (primary outcome) was successful in all cases in group V and in 29 (96%) cases in group D (P = 0.923). Amongst the secondary outcomes, the IDS of the majority in both groups was 1-4 (slight difficulty) (P = 0.98) and the mean TTI In group D was 34.6 s (SD = 19.0) (95% CI: 27.5-41.7) versus 39.8 s (SD = 5.2) (95% CI: 37.8-41.7) in group V (P = 0.151).
Conclusions:
There was no significant difference in the use of a VLS over a DLS in performing the left paraglossal laryngoscopy in terms of first-pass intubation rate, CL Grade, IDS and TTI. Further studies with different VLS may be done to improve the ease of this technique.
