Thakare DW, et al. - This prospective observational study compared the feasibility of infant (size 0), pediatric (size 1), and small (size 2) Airtraq (AT). Quick, easy, and excellent glottic visualization was afforded by all sizes of AT. However, failure rate for intubation with infant (size 0) was high compared to nil with pediatric (size 1) and small (size 2).

Methods

• Researchers used AT for endotracheal intubation in healthy pediatric patients of 3 months to 18 years age.
• The primary outcome was success of intubation which was noted as number (%) and analyzed using Fisher's exact test.
• The secondary outcomes were percentage of glottis opening (POGO) score, visual analog scale (VAS) for field of view, time to best view (TTBV), time to intubation (TTI), and VAS for ease of use and were presented as median (interquartile range) in each subgroup of sizes and analyzed using Kruskal–Wallis test.

Results

• Findings revealed that overall POGO score was 100 (100, 100 [50–100]) %, VAS field of view was 10 (10, 10 [5–10]), and TTBV was 6 (4, 10 [1.5–24]) s.
• Researchers found no statistically significant difference in any of the subgroups.
• They noted that the success rate of intubation with AT was 100% with AT size 1 and 2, whereas 45% with AT 0, P < 0.001.
• Data reported that VAS for ease of use was 5 (4, 10 [3-10]) with AT 0 compared to 10 (10, 10 [9–10]) with AT 1 and 10 (10, 10 [6–10]) with AT 2 (P < 0.001).
• In addition, researchers found that TTI was 28 (20, 36 [11.8-59]) s in those who could be successfully intubated.
