Re: GI biopsy blues

Donna Carlton suggests for facing GI tissue blocks:
>>Try hibaclens half and half with water for 10 min.<<

Hibiclens hand wash combines a mild detergent ("nonionic surfactant") with 
chlorhexidine (Hibitane), a "quat" disinfectant. I think using Hibiclens in 
microtomy is safe and reasonable, but it's not an entirely rational use of 
the product.

Chlorhexidine hand wash - the usual brand name is Hibiclens, but there are 
others, since chlorhexidine has been around since 1946 - is the best 
documented of germicidal hand washes that aren't too hard on your hands. For 
reasons I don't understand, Good Management prohibits its use, and an 
occasional hissy fit is necessary to keep the stuff on hand for when you 
really feel (and look) dirty after doing an autopsy.
