Background: It has been recommended that lightwand tracheal
intubation be used for cases in which there is difficult airway
management. Transillumination of the soft tissue of the neck by
the lightwand can lead to successful intubation; however, this
depends on skin color, obesity, head position, angle and the bent
length of the lightwand. The goal of this study was to compare
the success rates of intubation on the first attempt and complications
of lightwand orotracheal intubation that occurred when using the
lightwand at angles of 60o and 90o.
Methods: One hundred forty eight patients of ASA physical status
1 or 2 were enrolled in this study. Patients in whom intubation
had previously been difficult as well as patients who had the
potential for difficult intubation were excluded from this study.
Patients were randomly assigned to one of two groups: The
lightwand bent in 60o (LW60) group and the lightwand bent in 90¡o
(LW90) group. Anesthesia was performed using propofol (2 mg/kg),
fentanyl (1μg/kg) and rocuronium (0.9 mg/kg), and lightwand
orotracheal intubation was attempted 2 minutes after the induction
of anesthesia. The success rates of intubation, the number of
attempts and their duration, as well as hemodynamic changes,
resistance to the tube and complications that occurred during the
procedure were recorded.
Results: In the LW90 group, resistance to the tube during lightwand
intubation occurred in a significant number of patients (P ＜ 0.05),
however, there were no significant differences observed between
the two groups with regard to the intubation success rates on the
first attempt, the duration of intubation, hemodynamic changes and
complications.
Conclusions: Their were no significant differences observed
between intubation success rates on first attempt and complications
when using a lightwand bent to 60¡o or 90o in patients without any
previously known airway abnormalities.
