Intra operative heat loss
• Radiation – loss of heat from the patients body
•
•
•
to the environment.
Convection- loss of heat into the air currents.
conduction- loss of heat from the patients
body into a cooler surface such as the operating
table.
Evaporation- loss of heat via perspiration or
respiration.
Principles of aseptic technique

sterile field.
Sterile persons are gowned and gloved
Tables are sterile only at table level
Sterile persons touch only sterile items
or areas
• unsterile persons touch only
unsterile items or areas.
• Unsterile persons avoid reaching
over sterile field
• sterile persons avoid leaning over
unsterile area.
• Edges of anything that encloses
sterile contents are considered
unsterile
• Sterile field is created as close as
possible to time of use
• Sterile areas are continuously kept in
view
• Sterile persons keep well within
sterile area
• Unsterile persons avoid sterile areas
