We have measured pressure changes in a newly designed tracheal tube cuff, t
he Porter Soft Seal, during nitrous oxide anaesthesia compared with a Malli
nckrodt Lo-Contour tube and a Porter Profile tube. The pressure increases i
n both control groups were significantly greater than those with the new de
sign (P<0.0001 in each case). The mean increase in pressure in the Mallinck
rodt Lo-Contour tube cuff was 9.9 (SD 3.4) mm Hg compared with 10.3 (1.8) m
m Hg in the Porter Profile tube cuff and 2.1 (1.5) mm Hg in the Porter Soft
Seal tube cuff. We conclude that the Porter Soft Seal cuff prevented a sig
nificant increase in intracuff pressure during nitrous oxide anaesthesia.
