Abstract

BACKGROUND AND OBJECTIVES:

We investigated the usefulness of an Endoflex tracheal tube, the tip of which can be bent forward by pulling on a wire held in the hand, for oral and nasal endotracheal intubations without a stylet, in comparison with tracheal intubation using a conventional endotracheal tube and a stylet/Magill forceps.

METHODS:

The study participants comprised 40 patients for oral intubation and 20 patients for nasal intubation. Each group was then divided into control and Endoflex subgroups. In the oral intubation study, controls were intubated using a standard Macintosh-type laryngoscope with a conventional endotracheal tube with adjuvant use of a stylet, whereas the Endoflex group was intubated using a Macintosh-type laryngoscope with an Endoflex tube. In the nasal intubation study, controls were intubated by a standard Macintosh-type laryngoscope with an endotracheal tube for nasal intubation. Under direct vision, Magill forceps were used to guide the tip of the endotracheal tube into the glottis. Patients in the Endoflex group were intubated using a Macintosh-type laryngoscope with an Endoflex tube.

RESULTS:

Although haemodynamic changes during tracheal intubation did not differ between the groups, the duration of intubation was significantly shortened in the Endoflex groups in both studies.

CONCLUSION:

The Endoflex endotracheal tube represents a beneficial tool for smooth oral and nasal intubation without requiring assistance or adjuvant equipment.
