[Glidescope: a comparison of percentage of glottic opening score between middle size and large size handles].

BACKGROUND

The aim of the present study was to compare the percent of glottic opening score between middle-size (#3) and large-size (#4) handles during laryngoscopy using the GlideScope videolaryngoscope (GVL) in Japanese women.

METHODS

In 80 Japanese women receiving general anesthesia for surgical procedures, laryngoscopy was performed using GVL #3 handle and GVL #4 handle. We compared the percentage of glottic opening score between the two handles on each patient.

RESULTS

The percentage of glottic opening score was higher with GVL #3 handle than with GVL #4 handle [66 +/- 28% (mean +/- SD), vs. 53 +/- 34%, P < 0.05).

CONCLUSIONS

The use of GVL #3 handle is recommended for tracheal intubation for Japanese women.
