Influence of sequence on insertion time and number of attemps

Sequence	1	2	3	4	P value
Time [s]
LMA	28 ± 21.4	19.7 ± 15.8	25.3 ± 25.9	22 ± 21	0.36
Cobra	26.7 ± 18.4	34.8 ± 35.1	29.6 ± 25.3	35.9 ± 30.5	0.47
LT	19.6 ± 13.4	20.74 ± 19.9	23.4 ± 13.9	23.8 ± 17.4	0.57
FT	22.5 ± 25.1	15.7 ± 5.9	14.9 ± 5.7	18.4 ± 11.7	0.13
Attempts [n]
LMA	1.36 ± 0.59	1.14 ± 0.35	1.22 ± 0.54	1.12 ± 0.53	0.31
Cobra	1.37 ± 0.59	1.45 ± 0.78	1.37 ± 0.59	1.58 ± 0.77	0.52
LT	1.25 ± 0.56	1.32 ± 0.58	1.36 ± 0.59	1.48 ± 0.7	0.46
FT	1.02 ± 0.35	1.02 ± 0.16	1.02 ± 0.16	1.08 ± 0.28	0.19

No significant difference between LMA, Cobra, LT and FT regarding the sequence of use could be demonstrated for the time of insertion or the attemps needed. Data are presented as means +/- standard deviation
