TaperGuard™ – the Low-Impact, Low-Pressure Endotracheal Tube Option

The Shiley™ TaperGuard™ oral/nasal endotracheal tube features a better sealing cuff that reduces secretions entering the lower respiratory tract by 90%([FOOTNOTE=Mallinckrodt™ TaperGuard™ endotracheal tube and Mallinckrodt™ TaperGuard™ Evac endotracheal tube 510(k)#090352 benchtop testing.],[ANCHOR=],[LINK=]) and exerts 29% less pressure([FOOTNOTE=Lichtenthal PR, Wood L, Wong A, Borg U. Pressure applied to tracheal wall by barrel and taper shaped cuffs. Paper presented at: Annual Meeting of the American Society of Anesthesiologists; October 15-19, 2011; Chicago, IL. Abstract A1054.],[ANCHOR=View Abstract],[LINK=/content/covidien/websites/medtronic/com/en/covidien/support/clinical-evidence.html?id=805252]) on the trachea.*

Given the impact of silent aspiration, the TaperGuard™ cuff technology could be a cost-effective strategy to improve patient outcomes and reduce hospital costs.

Friction or pressure between the tracheal cuff and the trachea’s sensitive mucosa can lead to irritation, ischemia and tracheal trauma.([FOOTNOTE=Liu J, Zhang X, Gong W. Correlations between controlled endotracheal tube cuff pressure and postprocedural complications: a multicenter study. Anesth Analg. 2010;111(5):1133–7.],[ANCHOR=],[LINK=]),([FOOTNOTE=Seegobin RD, van Hasselt GL. Endotracheal cuff pressure and tracheal mucosal blood flow: endoscopic study of effects of four large volume cuffs. Br Med J (Clin Res Ed). 1984;288(6422):965–968.],[ANCHOR=],[LINK=]) Endotracheal tubes with TaperGuard™ cuff technology have features that may help reduce the tracheal impact of intubation with a unique, taper-shaped cuff design that provides a smaller area of contact with the patient’s airway than traditional barrel-shaped cuffs.4

Unique TaperGuard™ cuff design:

  • Exerts 29% less pressure on the trachea2
  • Reduces intracuff pressure required to obtain an adequate seal compared to Shiley™ Hi-Lo cuffs([FOOTNOTE=Tsuboi S, Miyashita T, Yamaguchi Y, et al.. The TaperGuard endotracheal tube intracuff pressure increase is less than that of the Hi-Lo tube during nitrous oxide exposure: a model trachea study. Anesth Analg. 2013;116: 609–612.],[ANCHOR=],[LINK=])
  • Provides more uniform pressure distribution than Shiley™ Hi-Lo cuffs at equivalent intracuff pressures2
  • Reduces microaspiration by as much as 90% compared to Shiley™ Hi-Lo cuffs([FOOTNOTE=Lichtenthal PR, Maul D, Borg U. Do tracheal tubes prevent microaspiration? Br J Anaesth. 2011;107(5):821-822.],[ANCHOR=],[LINK=])
