Table 2. Intubation metrics of difficult airway.

Parameter	Video Stylet n = 21	Video Laryngoscope n = 21	P value
Total time to intubate, sec, median [IQR]	17 [13.5–25]	23 [18.5–26.5]	0.031
Time from lips to stable glottis view, sec, median [IQR]	10 [6.5–12]	12 [8.5–15.5]	0.036
Time from stable glottis view to ETT intubation, sec, median [IQR]	7 [4.5–10]	8 [6–9.5]	0.31
Time from ETT intubation to removal of device, sec, median [IQR]	1 [1–1]	2 [1–2]	0.0002
VAS score of ease of intubation, median [IQR] {0 = easy, 10 = difficult}	2 [2–3]	4[3–5]	0.0007
1st attempt success (%)	100	100
POGO %, median [IQR]	100 [100–100]	10[10–25]	<0.0001

IQR = interquartile range; POGO = percentage of glottic opening; VAS = visual analogue scale
