1
Q

sepsis - define

A

pathogens +/- toxic substances in tissue

2
Q

asepsis - define

A

absence of pathogenic microbes in tissue

3
Q

antisepsis - define

A

prevention of sepsis by destruction/inhibition of microorganisms

4
Q

antiseptic - define

A

chemical that kills/inhibits pathogens - applied to the body

5
Q

disinfectant - define

A

chemical that kills/inhibits pathogens - applied to inanimate objects

6
Q

sterilisation - define

A

complete elimination of microbial viability, incl spores, physically/chemically

7
Q

chlorhexidine

A

kills broad spec of bacteria - no spores, variable for viruses
rapid initial kill + residual activity

8
Q

iodine

A

kills bacteria, viruses, fungi - not spores
use on mucosal surfaces - not near open wounds
corrodes instruments + can cause contact dermatitis

9
Q

alcohol

A

kills broad spec of bacteria
enhances effect of chlorhexidine + iodine
corrodes instruments

10
Q

closed gloving

A

in most surgeries
needs long sleeve gown
gloves must cover cuff of gown

11
Q

open gloving

A

procedures that only need sterile hands

12
Q

methods of sterilisation of instruments

A

physical - heat, irradiation, filtration

chemical - ethylene oxide, disinfectants

13
Q

surgical infection - bacterial factors

A

presence, growth + no. of bacteria
type + virulence
duration of exposure
nature of contamination

14
Q

surgical infection - surgical factors

A
duration + technique
preparation
dead space + seroma
foreign material 
blood clots
devitalised tissue
15
Q

surgical infection - host risk factors

A

age
nutritional status
disease conditions
therapy

16
Q

antimicrobial prophylaxis - define + aim

A

administration of antimicrobials before contamination of surgical site
achieve + maintain MIC at surgical site for the duration of the procedure

17
Q

results of inappropriate antimicrobial prophylaxis

A

idiosyncratic drug reactions
resistant bacteria
suppression of normal bacterial flora
