Chlorhexidine Recommendations Raise Questions

Janet N. Siler, MD

To the Editor

After reading about the use of chlorhexidine (CHG) prep in the Spring 2003 issue the following questions come to mind:

  1. Is CHG potentially useful and possibly preferable for use in preparing the skin area prior to regional nerve blocks?
  2. Is CHG a problem for use on the face and mucous membranes?
  3. Is potential deafness a concern if CHG enters the ear canal?
  4. Should CHG be considered for preparation of the skin prior to insertion of a routine peripheral intravenous catheter or in special circumstances such as an immune compromised patient?

Any information regarding the above questions would be greatly appreciated.
