Comparison of Nasal Taper-guard Cuffed and a Nasal Cylindrical Endotracheal Tube

Comparison of the Endotracheal Tube Cuff Pressure Between a Taper-guard Cuffed Nasal Endotracheal Tube and a Cylindrical-shaped Cuffed Nasal Endotracheal Tube After Changing in Position of Head

This study was designed to evaluate the effect of change of head position on the cuff pressure of TaperGaurd endotracheal tube , compared to cylindrical endotracheal tube during oral surgery.

The patient in cylindrical group (n=26) were intubated with cylindrical shaped endotracheal tube (Unomedical, Kedah, Malaysia) and the patient in tapergaurd group (n=26) was intubated with TaperGuard endotracheal tube (Covidien, Athlone, Ireland). The group allocations were informed to the attending anesthesiologist prior to anesthesia. Tracheal intubation was performed with size of inner diameter 7.0 mm endotracheal tube for male and 6.5 mm endotracheal tube for female by the same anesthesiologist. The anesthesiologist measured cuff pressure and distance from endotracheal tube tip to carina during study period.This study was designed to evaluate the effect of change of head position on the cuff pressure of TaperGaurd endotracheal tube, compared to cylindrical endotracheal tube during oral surgery.

Inclusion Criteria:

• Patient who were underwent nasal intubation

Exclusion Criteria:

• history of difficult intubation, limited neck movement, respiratory diseases and body mass index more than 35 kg/m2
