Asepsis |
Prevention of microbial contamination of living tissue or sterile materials by excluding, removing or killing microorganisms including pathogens and spores
|
|
|
Aseptic technique |
Refers to a procedure that is performed under sterile conditions to prevent nosocomial infections - breaks the cycle of infection which limits the patients exposure to a number of microorganisms that is not detrimental |
|
|
Infection cycle |
susceptible host--> pathogenic micro-organism--> reservoir or source--> portal or exit--> method of transmission--> portal of entry (surgical wound?)--> susceptible host |
|
|
How can microorganisms gain access to a surgical wound? |
Whenever the skin is disrupted, microorganisms have the opportunity to invade tissue and proliferate |
|
|
Infection |
multiplication of an infectious agent within the body tissues that results in cellular injury |
|
|
Pathogens |
microorganisms that cause infection or diseases in humans and animals |
|
|
Nosocomial infection |
infection that is the result of treatment in a hospital |
|
|
Time period where it is considered nosocomial if .... |
it appears in 48 hours or more in the hospital or within 30 days of discharge |
|
|
Explain the causes and how to diagnose surgical site infection (SSI) |
MOST common form of nosocomial infection. Diagnose: Purulent discharge, signs of inflammation, isolation of microorganisms from wound |
|
|
biggest source of pathogens |
Endogenous flora of patients skin, mucous membranes and hollow viscera |
|
|
Explain the systemic inflammatory response syndrome (SIRS) |
can progress to this from SSI |
|
|
How to produce and maintain a sterile operative field |
proper preparation of facilities, environment, surgical site, surgical team, and surgical equipment |
|
|
recognizing a break in aseptic technique and respond appropriately |
damaged wrapper or wet wrapper |
|
|
Rules of aseptic technique in surgery lab |
wear proper attire, hands not folded into axillary region, no go below the waist, surgical team remain in sterile area (minimum movement), decrease talking, laughing, no sneezing or coughing in surgical area, sterile drapes, tables sterile only at table height, surgery equipment must be sterilized, edges of sterile containers are not considered sterile,non-scrubbed personnel don't reach over the sterile fields, never back to front -- just face to face or back to back, scrubbed personnel handle only sterile items, stand to sit okay |
