Comparison of Different Intubation Methods in Difficult Airways during Simulated Cardiopulmonary Resuscitation with Continuous Chest Compression: A Randomized Cross-Over Manikin Trial

Table 1

Intubation success rates, time, and ease in the analysed groups.

Parameter	Intubation method			p-value
	Without Bougie (A)	Standard Bougie (B)	New Bougie (C)
Overall intubation success rate, n (%)	40 (86.9%)	46 (100%)	46 (100%)	A vs. B = 0.028
				A vs. C = 0.028
				B vs. C = NS
Intubation success rate, n (%)				A vs. B <0.001
attempt	11 (23.9%)	34 (73.9%)	42 (91.3%)	A vs. C <0.001
attempt	20 (43.4%)	12 (26.1%)	4 (8.7%)	B vs. C = 0.047
attempt	9 (19.6%)	-	-
Intubation time, s (IQR)	47.5 (36-58)	38 (31-44.5)	29 (25-38)	A vs. B = 0.015
				A vs. C = 0.002
				B vs. C =0.038
				Ease of use, VAS score (IQR)	85 (63-88)	44 (30-51)	32 (19-41)	A vs. B <0.001
A vs. C <0.001
B vs. C = 0.043

NS: not significant; IQR: interquartile range; VAS: visual analogue scale, from 1 (extremely easy) to 100 (extremely difficult).
