PLEASANTON, Calif. -- Nellcor, part of Tyco
Healthcare, today announced that two studies presented at the American
Association for Respiratory Care (AARC)'s 49th Annual International Respiratory
Congress, held in December 2003, found the Mallinckrodt-brand
Hi-Lo Evac Endotracheal Tube from Nellcor greatly reduced rates of
ventilator-associated pneumonia (VAP).
VAP refers to nosocomial pneumonia that develops in mechanically
ventilated patients (1). It is recognized to be one of the most serious and
costly hospital-acquired infections. One case of VAP can result in more than
$40,000 in additional hospital costs (2). In the United States, VAP is
estimated to result in $1.5 billion in excess expenditures and 1.75 million
additional hospital days each year (3).
One way to reduce episodes of VAP is through the continuous aspiration of
subglottic secretions, which is facilitated by the Hi-Lo Evac Endotracheal
Tube. Researchers from Sentara Healthcare in Virginia Beach, Va., conducted a
study to determine how using the Hi-Lo Evac Endotracheal Tube in place of
conventional ET tubes would impact VAP rates in a community-based general
intensive care unit (ICU).
Compared with the previous year, use of the Hi-Lo Evac Endotracheal Tube
resulted in a 52 percent decrease in VAP rates. This study was consistent with
controlled studies reporting a 40 percent to 50 percent reduction in VAP rates. Sentara
Healthcare now uses the Hi-Lo Evac Endotracheal Tube as a standard of care in
its ER, ICUs and crash carts.
"We believe the Hi-Lo Evac Endotracheal Tube is an important component in
our efforts to promote patient safety," said Paul Garbarini, MS, RRT, Sentara
Healthcare. "The Agency for Healthcare Research and Quality's 'Making Health
Care Safer: A Critical Analysis of Patient Safety Practices' listed continuous
aspiration of subglottic secretions in its highest recommendations for Patient
Safety Practices. We have since expanded Hi-Lo Evac therapy to a second
hospital and achieved similar results."
Researchers from Deborah Heart and Lung Center in Browns Mills, N.J.,
conducted a study to evaluate the Hi-Lo Evac Endotracheal Tube as an adjunct
in managing VAP. During a three-month period, all patients at Deborah Heart
and Lung Center were intubated with the Hi-Lo Evac Endotracheal Tube.
Patients transferred from other facilities and those in the ICU who were
already intubated were exempted.
During the study period, the VAP rate at Deborah Heart and Lung Center
dropped below the national average of 10.5 incidence/1,000 days. The
researchers are now collecting data for a one-year period and will reevaluate
"The Hi-Lo Evac Endotracheal Tube from Nellcor has been an important asset
in combating VAPs," said John J. Hill, RRT, Deborah Heart and Lung Center.
"This strategy has enabled our patients to be at ease with lowered infection
rate outcomes. We are proud to be including this device with all our surgical
With its integral suction lumen, the Hi-Lo Evac Endotracheal Tube is designed to provide
a safe, convenient way to remove secretions above the endotracheal tube cuff.
Using theHi-Lo Evac Endotracheal Tube in place of standard endotracheal tubes
can help decrease the occurrence of VAP, which may lead to reduced costs and
