Abstract
Purpose Positional change can displace an endotracheal
tube (ETT) and change the ETT cuff pressure in a
tracheally intubated patient. Endotracheal tubes with
different cuff shapes may lead to different cuff pressures
after positional change. We hypothesized that the intracuff
pressure in the TaperGuardTM ETT with a tapered-shaped
cuff would be higher than that in the conventional ETT with
a cylindrical-shaped cuff after a change from the supine to
the lateral flank position.
Methods Fifty-eight patients scheduled for open
urological procedures in the lateral flank position were
randomly allocated to receive either a TaperGuard ETT
(group T) or conventional ETT (group C). The ETT cuff
pressure was initially set at 20 cm H2O in the supine
position and was measured after the change to the lateral
flank position. The distance from the ETT tip to the carina
was measured in both the supine and the lateral flank
positions.
Results Two patients, one from each group, were
excluded from the data analysis. The mean (SD) ETT cuff
pressure was significantly higher in group T (n = 28) than
in group C (n = 28) after the change in position [31 (7) cm
H2O vs 25 (4) cm H2O, respectively; mean difference, 6
cm; 95% confidence intervals [CI], 3 to 9; P\0.001]. The
mean (SD) proximal migration of the ETT tip was
comparable between the two groups [8 (18) mm vs 4 (14)
mm, respectively; P = 0.367].
Conclusions After the change from the supine to the
lateral flank position, the ETT cuff pressure was
significantly higher in the TaperGuard ETT than in the
conventional ETT, although the extent of cephalad
displacement of the ETT was comparable between the
two groups. This trial was registered at Clinicaltrials.gov:
NCT02165319.
