In: Dental treatment

14 Nov 2009

Average (SD) LMA insertion times per student for the nil practice group (group 1), 5 times practice group (group 2), and 10 times practice group (group 3) were 15.8 ± 3.0, 12.0 ± 2.7, and 9.1 ± 1.7 seconds, respectively.

Kruskal-Wallis tests were used to compare differences for all 3 groups, and Fisher exact tests were used to compare differences between 2 groups. P < .05 was regarded as significant. Insertion times for groups 2 and 3 were significantly faster than group 1, and group 3 was significantly faster than group 2 (P < .05) (Figure 3). Group 1 (average = 2.8) had poor placement grades (C = 10, В = 2, A = 0). Group 2 (average = 1.4) and group 3 (average =1.3) had superior placement grades compared with group 1, but groups 2 (C = 1, В = 4, A = 7) and 3 (С = 0, В = 4, A = 7) were not significantly different (P < .05) (Figure 4). Technical indexes for groups 1, 2, and 3 were 44.4 ± 9.7, 16.5 ± 7.2, and 12.3 ± 5.3, respectively. Groups 2 and 3 varied significantly from group 1; however, groups 2 and 3 were not significantly different (Figure 5). levitra plus
