Data of endotracheal intubations
| CVS-V group (n = 50) | CVS-L group (n = 50) | DL group (n = 50) | p value | |
|---|---|---|---|---|
| Patients successfully intubated | ||||
| At the first attempt within 30 s | 47 (94) | 38 (76) | 47 (94) | 0.006 |
| At the first attempt within 60 sa | 49 (98) | 44 (88) | 49 (98) | 0.037 |
| Success within 30 s (including two attempts) | 47 (94) | 41 (82) | 47 (94) | 0.069 |
| Success within 60 s (including two attempts) | 49 (98) | 48 (96) | 49 (98) | 0.773 |
| Median time to successful intubation at the first attempt (s) | 10.6 (7.5 to 13.7) | 14.6 (11.1 to 18.0) | 16.5 (15.7 to 17.3) | 0.023b |
Values are shown as number (%) or median (95% CI)
a Intubation tools at the second attempt were the same in both CVS-V and CVS-L group. In the DL group, CVS-V was used in this case due to unseen glottis at the first attempt
b Data from Kaplan-Meier estimator with p value of log-rank test. However, after Sidak’s adjustment for multiple comparisons for the log-rank test, the p values were all more than 0.05 in three comparisons (p = 0.0566 between CVS-V group and CVS-L group, p = 0.0762 between CVS-V group and DL group, and p = 0.9998 between CVS-V group and CVS-L group)
