7. Preparation of the patient and the operative site (until draping can be performed) Flashcards
- Preparation of the patient and the operative site (until draping can be done)
Preparation of the operative site:
-preoperative preparation reduces the number of bacteria and the
likelihood of infection
-sterilizing skin without impairing its natural protective function and interfering with wound healing is impossible
-antisepsis!
Preparation of the patient:
-treatment of any infections if elective surgery
-dietary restrictions
-excretions
-confirmation of the patient’s identity, the surgical procedure and surgical site
-treatment of hair
Removal of hair:
-immediately before surgery (infection risk)!
-outside the operating theatre
-clipping initially done with the hair growth pattern, then against
-loose hair removal (vacuum)
-prepared area should be large enough to accomodate extension of the incision (20 cm on each side of the incision)
-paws can be excluded from the surgical area by placing a latex glove
General cleansing rub:
-prepuce is flushed with antiseptic solution (antiseptic solution=chemical compounds inhibiting the growth of
microorganisms without necessarily killing them)
in case of abdominal procedures in male dogs
-skin is scrubbed with germicidal soaps and warm water to remove
derbis and reduce bacterial populations
-incision site → moving from the center to the periphery, exceptions: infected wound, abscess
-until all dirt and oils have been removed
-antiseptic is applied
‘’Sterile“ skin preparation:
-should be done after positioning the patient
-purposes of the preoperative skin preparation:
>to remove soil and transient microorganisms
>to reduce the resident microbial count to subpathogenic levels with the least
amount of tissue irritation
>to inhibit rapid rebound growth of microorganisms
-aseptic technique
>antiseptics are used (chlorhexidine gluconate > povidone-iodine?)
>gloved hands
>avoid contaminating sponges/gauze swabs
>from the center to the periphery, then discard
Draping:
-creating and maintaining a sterile field around the operative site with nonabsorbant towels
-performed by a gowned and gloved team member when antiseptics have dried
-one at a time
-drapes should not be flipped or shaken
-once placed, should not be readjusted
-after the animal and nearby nonsterile surfaces have been cover
