disinfection of field of operation


Also found in: Dictionary, Thesaurus, Encyclopedia.

disinfection of field of operation

Disinfection of the area of the body where surgery is to be performed. Universally accepted fields of preparation for most surgical procedures have been widely published. Preparation should extend well beyond the operative site. A variety of disinfection solutions are available, including povidone-iodine, benzalkonium chloride, and chlorhexidine gluconate. These agents may be used in aqueous or soap-based preparations. Mucous membranes may be cleansed by nonirritating agents or not at all.

CAUTION!

The mucous membranes are active, absorbing surfaces, and therefore solutions of some potent antiseptics may not be used in these areas. In the past, the use of mercury-based antiseptics in the vagina, uterus, or rectum resulted in serious poisoning and in some instances death.
