Oropharyngeal leak pressure and fibreoptic position of the airway tube

	Propofol + saline	Propofol + remifentanil
	(n = 32)	(n = 26)
Oropharyngeal leak pressure (cm H2O)	22 (3) [21–23]	26 (6) [23–29]*
Fibreoptic position 4/3/2/1 n (%)	11(39)/1(4)/4(14)/12(43)	6(26)/3(13)/8(35)/6(26)

Data are mean (SD) [95 % CI] or percentages

The fibreoptic position was available in 28 patient in propofol + saline group and in 23 patients in propofol + remifentanil group

1 = vocal cords not seen; 2 = vocal cords plus anterior epiglottis seen; 3 = vocal cords plus posterior epiglottis seen; 4 = only vocal cords visible
