A few months ago, NAHAM News reported on the spread of
so-called “superbugs” in medical facilities across the county (Superbugs
are invading U.S. Healthcare Facilities). These bugs, such as
Staphylococcus and Clostridium difficile, are difficult to prevent and
impossible to treat. The superbugs come into medical facilities without warning
and infect patients regardless of the patient’s original illness. Try as they
might, doctors have not been able to come up with a way to fight the infections;
even the strongest antibiotics haven’t worked. Without a treatment method,
hospital staffs have turned to a preventative approach with the strategy of
stopping the bugs from infecting patients in the first place.
Doctors at Johns Hopkins Hospital in Baltimore are trying
new technologies in their struggle to prevent these bugs, and for the past few
years they have been using robots. According to NPR,
the robots that the hospital is now using spray a toxic dose of hydrogen
peroxide into hospital rooms to sanitize the room and kill any bacteria. This
treatment could have been helpful in a case at the National Institute of Health
in Bethesda, Maryland, where bacteria were found in the pipes below a patient’s
sink.
In order for the treatment to be safe and effective, the
room must be sealed and the hydrogen peroxide must touch all the surfaces. A
technician prepares each room by sealing up air vents and opening drawers. The
tech then tapes the door shut from the outside before staring the robot. For 30
minutes, the hydrogen peroxide mist is sprayed in the room. While the hydrogen
peroxide mist is odorless and colorless, any person entering the room would be
unable to open eyes or breathe. Once the hydrogen peroxide mist has done its
work, the robot emits a second chemical that turns the hydrogen peroxide to
water, making it safe to enter and prepare the room for the next patient.
The robots, comparable in appearance to a domestic washing
machine or trash can, have proven effective. Johns Hopkins recently reported
that the number of untreatable infections has fallen by 64 percent since the
hospital began using the robots. While these robots are not a modern day cure-all,
Johns Hopkins is hoping that other hospitals follow suit and start using their
own hydrogen peroxide robots.
