Effect of Modified Stylet Angulation on the Intubation With GlideScope® (GlideMStylet)

Keimyung University

Status: Completed

Conditions: Cholecystitis; Stomach Cancer

Treatments: Device: GlideScope®; Procedure: Glidescope guided intubation

Study type: Interventional

Funder types: Other

Identifiers

NCT02547064

GlideMStylet

Details and patient eligibility

About

The GlideScope® videolaryngoscope usually visualize glottis better than the conventional laryngoscope. Under the visualization of glottis by GlideScope®, the insertion of endotracheal tube, however, is challenging.

The goal of this study was to determine which of two stylet (70° vs 90°) was better, as determined by time to intubation.

Enrollment: 162 patients

Sex: All

Ages: 18 to 80 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

162 participants in 2 patient groups

90 degree

Active Comparator group

Description:

The ETT with the 90° angle stylet was bent at a point 8 cm from its distal end.

Treatment:

Procedure: Glidescope guided intubation

Device: GlideScope®

70 degree

Experimental group

Description:

The ETT was bent by 70° at a point 6 cm from its distal end and the proximal portion of the ETT was formed as the shape of the GL blade until the point of the handle.

Treatment:

Procedure: Glidescope guided intubation

Device: GlideScope®
