Q

if your sx patient has neoplasia, what do you want to look for & what additional diagnostics do you want to run before going to surgery?

A

we want to evaluate the patient for metastasis.
we can do this by thoracic radiographs, abdominal ultrasound, lymph node aspirate

Q

if your sx patient has experienced trauma, what diagnostics do you want to do before going to surgery?

A

thoracic radiographs
(patient could have a diaphragmatic hernia, pneumothorax, pleural effusion, pulmonary contusions –> these all decrease the chances of doing well under anesthesia)

Q

what needs to be signed by the owner prior to surgery?

A
  • a waiver authorizing surgery and accepting anesthetic/surgical risks
  • an estimate outlining anticipated costs
30
Q

what should you do regarding patient stabilization before induction of anesthesia?

A

replace fluid deficits and correct acid base and electrolyte abnormalities

31
Q

what should ALL animals receive while undergoing general anesthesia and surgery? (including healthy animals having elective procedures)

A

intravenous fluids

32
Q

what dietary restrictions should be followed for adult animals undergoing surgery?

A

food intake should be restricted 6-12 hours before induction of anesthesia

33
Q

why is fasting important before induction?

A

to avoid intraoperative or postoperative emesis and aspiration pneumonia

34
Q

what dietary restrictions should be followed for young animals undergping surgery?

A

food should not be withheld longer than 4-6 hours before induction due to possible hypoglycemia

35
Q

what is a surgical site infection?

A

infection that directly results from surgical procedures that involve other areas of the body as well such as organs or internal spaces that are manipulated during the operation

36
Q

what is the most common source of SSI’s?

A

endogenous microbial flora (staph & strep)

37
Q

what is an incisional SSI?

A

infection of the actual site of surgical incision (can be superficial or deep)

38
Q

what does a superficial incisional infection involve?

A

skin and subcutaneous tissue

39
Q

what does a deep incisional infection involve?

A

soft tissue layers such as incisional fascia and muscle

40
Q

what is an organ/space SSI?

A

infection of an anatomic part that was manipulated during the operation (ex: pissing off the pancreas)

41
Q

CDC classification of an SSI includes:

A

SSI infection must occur within 30 days of surgical procedure, occur within 1 year if it is associated with a surgical implant

42
Q

what normal resident organisms live in the skin’s superficial cornified layers and the outer hair follicles of dogs?

A

staphlococcus epidermidis, corynebacterium spp, pityrosporum spp

43
Q

what flora must we eliminated expsure to during surgery?

A

resident and transient flora

44
Q

can you sterilize skin without impairing its natural protective function and interfering with wound healing?

A

no, impossible

45
Q

what is the purpose of preop preparation regarding possible infection?

A

it reduces the number of bacteria and the likelihood of infection

46
Q

antisepsis is

A

the prevention of sepsis by preventing/inhibiting growth of resident and transient microbes

47
Q

antiseptic

A

product with antimicrobial activity that formerly may have been referred to as an antimicrobial agent (an agent capable of producing antisepsis)

48
Q

what two options do we have for antisepsis agents?

A

chlorhexadine gluconate and povidone iodine

49
Q

what antisepsis agent is superior?

A

CHG

50
Q

prevalence if SSI in humans is a major concern because of the associated…

A

increase incidence of morbidity, mortality, length of hospitlization and cost of care for post op patients

51
Q

preventive preop measures that can reduce the risk of SSI include:

A
  • antimicrobial prophylaxis
  • proper utilization of skin antiseptic agents for surgical team and patient
