Trachestomal care:       Dilute betadine solution (1:20 dilution in saline of 10% solution) applied to a drain sponge placed under the flanges of the tracheotomy tube for 10 minutes once - to - several times per day is then followed by placement of dry drain sponge.

Regarding:  Instructions for Betadine Soaked Dressing to Stoma



  • Drainage sponges
  • Dilute betadine solution
  • Dilute Betadine Solution:
    • Betadine Solution (10% Povidone-iodine)
    • 0.9% Normal Saline
    • Mix betadine and saline together  - make new batch every day
      • ~40cc normal saline
      • ~2-3cc betadine


Soak the T-cross area of the drainage sponge with ~5cc dilute betadine solution. Don’t soak the whole sponge.  Use both sponges in the package to ensure the betadine is actually touching the skin at the trach site.

Leave betadine sponge in place for ~10 minutes.  Then remove and place a clean dry drainage sponge. 

Apply betadine sponge 2 times per day

Replace clean/dry drainage sponge as needed to keep tracheostomy site/skin dry


Use of topical preparation with betadine solution has been found useful in decreasing infection associated with C-section (Yildirim 2012) and is also widely used in opthalmic surgery - with recent reports suggesting benefit to 1.25% povidine-iodine solution with the addition of topical levofloxacin (Ikuno 2012).  A 0.035% povidone-iodine preparation (1:20 dilution of 7% preparation (popiyodon gargle R povidone-iodine (PVP-I) was found to be an effective bactericidal mouth was by Oyanagi in 2012. 

Four reported cases (ref: Chepla 2012) of interstitial pneumonitis have been reported from betadine aspiration -- including documented aspiration of an estimated 2 cc of 10% solution in a 7 year old patient. Chepla and Gosain conclude that the report of this "very rare complication" following use of this very effective antimicrobial should not preclude its appropriate use, but should modify its use to decrease exposure of the tracheobronchial tree.   Our approach to the use of dilute betadine applied to a drain sponge is to apply an approximately 1:20 dilution of a 10% betadine solution (0.5%) to make it look like 'very dilute tea' for a 10 minute application to the moistened drain sponge before removal and replacment with a dry sponge.

We have had notable success in diminishing granulation tissue about tracheostomes with this technique and no observed pulmonary complications.

A prospective randomized study comparing 10% povidone-iodine with chlorhexidine-alcohol skin prep showed a 40% higher surgical infection rate with the iodine preparation than the alcohol based preparation (Darouiche et al 2010). The authors conclude that the superior clinical protection provided by chlorhexidine--alcohol is probably related to its more rapid action, persistent activity despite exposure to bodily fluids, and residual effect. The potential toxicity of chlorhexidine-alcohol compared to dilute (0.05% betadine solution) has prevented us from adopting its use in our tracheostomal care.
