Compliance characteristics of the Portex Soft Seal Cuff improves seal against leakage of fluid in a pig trachea model
Background:
The Portex Soft Seal high-volume, low-pressure cuffed tracheal
tube was compared with the Mallinckrodt HiLo, Sheridan Preformed and Portex
Profile tracheal tubes for leakage of dye placed in the subglottic space of a
pig's trachea which was used in a benchtop mechanical ventilation model
and in six isolated pig tracheas.
Results:
There was no leakage, either in the ventilation model or in the
isolated tracheas in the Portex Soft Seal group. There was rapid leakage in the
ventilation model and in all the isolated tracheas for the Mallinckrodt HiLo,
and five out of six isolated tracheas for the Sheridan Preformed and the Portex
Profile group.
Conclusions:
This benchtop study suggests that the improved compliance
characteristics of the Portex Soft Seal cuff are beneficial in preventing
leakage of fluid in these models.
