Coating Ventilator Tubes Reduces Pneumonia


A study funded by C. R. Bard Inc. (Murray Hill, NJ) found that coating ventilator tubes with silver reduces the risk of pneumonia by as much as 36%.

Ventilator tubes commonly cause infections that lead to hospital-acquired bacterial pneumonia. Half of the antibiotics used in hospital intensive-care units are prescribed to help prevent bacterial pneumonia in patients put on ventilators.

Silver is widely used as an antimicrobial agent and has been shown to reduce bacterial pneumonia infections in animals. So Bard wanted to see whether a silver coating would help reduce the infections in humans.

The answer was affirmative. The study, published in August in the Journal of the American Medical Association, found that 4.8% of gravely ill patients on ventilators with silver-coated tubes acquired pneumonia, compared with 7.5% of patients on ventilators with uncoated tubes.
