Operation time of each group.

Groups	Time (seconds)
	1st time	2nd time	3rd time	4th time	5th time	Average
Endotracheal intubation group	251	168	232	192	203	209.2 ± 32.7
LMA group	73	72	67	74	75	72.2 ± 3.1
I-gel group	59	54	49	52	49	52.6 ± 4.2

. The bite block dropped and drifted away. Tukey’s post hoc test showed that the operation time of the endotracheal intubation group was significantly longer than that of the LMA group (209.2 ± 32.7 seconds vs. 72.2 ± 3.1 seconds, ) and I-gel group (209.2 ± 32.7 seconds vs. 52.6 ± 4.2 seconds, ). The operation time of the LMA group was 72.2 ± 3.1 seconds, which was not significantly longer than that of the I-gel group (52.6 ± 4.2 seconds, ).
