Suggestions for Wart Removal?

Dear Anak VGRD Members,

I am a G.P. trainee and have been having a hard time with a wart removal on a 3 year old's fifth toe. The difficulty is getting him to let anyone near it. I've seen him once, late in the day, and my preceptor asked that the child return for freezing with the help of sedation. We are now working on what to use. I prefer to avoid having to sedate the child, and have suggested duct tape in the interim (six days on, one day off with soaking). What suggestions or tricks would you have for treating a wart in this location in a three year-old? Thank you, Tammy Grimely, Hobart, Tasmania
