METHODS: Seventy neonates (American Society of Anesthesiologists physical status I and II, scheduled to undergo elective surgery under general anesthesia) were randomized to GS group (n = 35) and DL group (n = 35). The primary outcome variable of the study was TTI. As secondary outcomes, success rate of first intubation attempt of all neonates, intubation attempts, and adverse events were also evaluated. The glottic views (depicted by Cormack and Lehane [C&L] grades) obtained with GS and DL were compared.
RESULTS: There were no significant differences in TTIs of neonates with all C&L grades (95% CI, −7.36 to 4.44). There was also no difference in the subgroups of neonates with C&L grades I and II (n = 30 each; 95% CI, −0.51 to 5.04). However, GS significantly shortened the TTIs of neonates with C&L grades III and IV compared to DL (n = 5 each group; 95% CI, 4.94–46.67). GS improved the glottic view as compared to DL. Although the total tracheal intubation attempts in the GS group was fewer than that in the DL group (36 vs 41), there was no significant difference (P = .19).
CONCLUSIONS: GS use did not decrease the TTI of all neonates and neonates with C&L grades I and II as compared to DL use; however, GS significantly decreased the TTI of neonates with C&L grades III and IV. Additionally, GS use provided improved glottic views.
