Crede's maneuver requires the person inserting the catheter to apply manual pressure on the patient's lower abdomen over the bladder area to express urine. The application of pressure on the lower abdomen would contaminate an already prepped abdominal area. We have both flying and crawling insects.

Some liquid pesticides are acceptable for use in OR suites.
Pesticide applications in the OR should be performed commercially by people familiar with various pesticides and their characteristics and who have the appropriate equipment to perform a controlled application of the pesticide. Pesticides should be applied at a time when the daily OR schedule is complete. Exposed supplies should be covered with impervious material or moved to another location during the application. All pesticide residue must be removed after the pesticide application by cleaning the surgical suite and all exposed equipment thoroughly before the area and equipment are put back into service. The two documents are not the same, nor is one an update of the other.
