Tech in Surgery Prep / Unit 2 TSC 038 short lesson, about 20 seconds
Where Surgical Infections Come From
Captions available
The idea
Contamination of a surgical wound is either endogenous, from the patient's own flora, or exogenous, from outside the patient.
In practice
Endogenous sources include the patient's skin, bowel and mucous membranes; exogenous sources include the team's hands, the air, instruments and supplies.
Where people slip
Exogenous sources are the ones the scrub person directly controls through sterile technique, so they are never allowed to slip.
