Influence of Head and Neck Position on Oropharyngeal Leak Pressure and Cuff Position with the ProSeal Laryngeal Mask Airway and the I-Gel: A Randomized Clinical Trial

Table 7

Fibreoptic position between the devices.

Parameter	Fibreoptic view of glottis (4/3/2/1)		value
	ProSeal LMA	I-gel
Neutral	13/12/3/2	13/15/1/1	0.80
Flexion	11/8/6/5	8/11/8/3	0.57
Extension	15/11/2/2	11/13/4/2	0.41
Lateral rotation	11/12/5/2	8/15/5/2	0.95

Data shown in numbers. < 0.05 is considered significant.
Fibreoptic position was similar between the devices and the changes were insignificant in different positions.
