Endotracheal intubation in rabbits using a video laryngoscope with a modified blade

Table 1 Comparison of intubation using a CV and LV by an expert and novices

Type	Checkpoint	Expert (LAV, n = 1)	Novice (LAV, n = 2)
Conventional laryngoscope	Time to find the epiglottis	10 ± 1 s	141.8 ± 37.1 s
	Time for intubation	16.3 ± 1.2 s	Failed
	Intubation success rate	100%	0%
	Degree of damage	None	Edema and bleeding of the oropharynx
Video Laryngoscope	Time to find the epiglottis	5.3 ± 1.2 s	15.7 ± 4.8 s
	Time for intubation	26.3 ± 8.5 s	46.2 ± 18.8 s
	Intubation success rate	100%	100%
	Degree of damage	None	None

The expert (n = 1) is a LAV with more than 15 years of experience and the novices (n = 2) had less than 3 years of experience. The time required to find the epiglottis and perform intubation was the average for the three cases in which intubation was performed within 5 min after inducing anesthesia. The expert required less time to find the epiglottis when using a VL, but the time to intubate was faster for a CL. In the novice, the time needed to find the epiglottis was much shorter and intubation was successful when using a VL, but was not successful when using a CL. In both the expert and novices, intubation was possible without damaging the oropharynx when a VL was used, but swelling and bleeding were observed when the novices used a CL
