To the Editor:
I would like to thank Wang et al.  for their interest in our
study comparing the ﬁberscope and the ultrasound guided
techniques for tracheal intubation in patients with cervical
spine immobilization. Actually, in the technique described
in the study, the rigid neck collar was removed before tra-
cheal intubation to shape the tracheal tube mounted over the
stylet according to the previous lateral view X-ray taken in
the neutral position. However, some types of cervical neck
collars are available having a front window that allow ultra-
sound examination of the airway.
I agree with Wang et al.  that the experience in ultra-
sound-guided tracheal intubation is critical for its success.
The operator in the ultrasound group has been stated to have
7 years of experience in the application of ultrasound in
the airway and the intensive care including conﬁrmation of
tracheal intubation. The operator also observed the perfor-
mance of the technique in 20 cases before the beginning of
the study; however, they were not belonging to the popula-
tion of the present study. A number of our staﬀ members
have been now well trained with technique and a large study
is now being processed on a wide variety of patients.
