Why am I receiving MRSAid ™ treatment?

Doctors now know that patients carrying certain types of bacteria in their nose are at a greater risk for infection after surgery. By eliminating these bacteria from the nose and other skin surfaces before surgery, the risk of developing an infection at your incision site after surgery is greatly reduced. As a patient, you may be given MRSAid™ treatment in order to maximize the quality of your care and to reduce the likelihood of developing an infection during your hospital stay.

How is it done?

Prior to a hospital admission or procedure, a nurse will prepare you for MRSAid™ treatment. You will first be asked to blow your nose to remove any mucous that could interfere with treatment. The nurse will then apply a blue-coloured solution inside each of your nasal passages using a soft foam swab. After this, plastic tips will be placed in each of your nostrils and you will be asked to hold them in place for about two minutes while a red light is turned on. You should breathe normally during treatment, although some patients prefer to breathe through their mouth during the procedure. You may also choose to wear light-blocking glasses while the light is being used; however the light itself is not dangerous. This procedure will be repeated one more time to make sure that potentially harmful bacteria are killed.

How often should I be treated using MRSAid™?

Typically, you will be given MRSAid™ treatment before a period during which you will be at high risk for developing an infection. Examples of such times include surgical, intensive care, and dialysis procedures. MRSAid™ treatment may also be given in order to prevent you from bringing harmful bacteria into an area where others are at high risk for infection. MRSAid™ is a localized, acute method of eliminating high numbers of bacteria living on a tissue surface. As such, a single treatment using MRSAid™ does not prevent bacteria from re-colonizing your nose at a later date. In a similar way to washing your hands with an antibacterial soap, MRSAid™ treatment will only ensure that your nose is free of bacteria for up to a few days after treatment. For this reason, at your doctor’s discretion you may be given MRSAid™ treatment more than once during your time in the hospital.

Benefits of MRSAid™ treatment

  • MRSAid™ treatment can result in immediate elimination of S. aureus and/or MRSA from your nose at the times when you are at highest risk for infections
  • MRSAid™ treatment will reduce the risk that you will pass on potentially harmful bacteria to others around you
  • MRSAid™ treatment will eliminate the need for you to apply antibiotic gels into your nose for days prior to your hospital procedure
  • MRSAid™ doesn’t work like regular antibiotics, so the bacteria in your nose do not develop resistance to the treatment

Is MRSAid™ Treatment Safe?

Careful studies have been done to show that MRSAid™ treatment does not cause damage to the inside of your nose. In fact, the entire treatment should be painless to receive. The blue solution that will be swabbed into your nose has a long record of safety in medical use, and the red light does not give off heat. A similar product to MRSAid™ has been used by dentists across Canada since 2006 to treat bacteria in the mouth, and so far from over 70,000 treatments, no signficant adverse events have been reported. Nevertheless, please notify the healthcare professional treating you if you experience any discomfort while receiving MRSAid™ treatment.

What are some of the potential side effects of MRSAid™?

  • Possible irritation of the skin to the dye
  • Possible recurrence of bacterial colonization in the nose from re-inoculation of bacteria from another source
  • Possible sensation of warmth with therapy
  • Possible reduction but not complete elimination of bacteria

Will the blue MRSAid™ solution stain my clothes or skin?

The blue MRSAid™ solution that will be applied inside your nose, while not harmful, may permanently stain clothing if spilled or mishandled. You should be offered a protective gown or bib before treatment to avoid this if you are wearing street clothing. Minor blue staining of the skin around your nostrils may occur immediately after treatment. This staining should disappear within a couple hours, and can often be removed completely by washing the area with soap or an alcohol wipe.
