Deck 3 Flashcards
(15 cards)
Definition of asepsis.
Absence of pathogenic microbes on living tissues.
Ethylene oxide for sterilizing at what temperature?
25-55°C.
Lower temperature need longer exposure time.
(Or 37-63°C ??)
3 types of haemostatic forceps.
- Mosquito.
- Kelly.
- Crile.
Haemostatic forceps: Crushing instruments used to temporarily clamp and occlude bleeding vessels. Equipped with ratchet mechanisms to keep clamped even without hands. Straight or curved.
Contra-indication of capillary suture material.
Should NOT be used in contaminated or infected sites.
- Capillarity is a process by which fluid and bacteria are drained into the interstices of multifilament fibres → bacteria’s get stuck in the fibres.
Classification of sutures according to apposition of tissue.
(How the 2 ends of the wound will meet)
Appositional - End to end.
Everting - Protruding upwards.
Inverting - Protruding inwards.
Phases of wound healing.
Inflammation and debridement.
Proliferation.
Maturation and remodeling.
Types of open wound (name7).
(SLAADSP)
Surgical incision.
Laceration.
Abrasion.
Avulsion.
Degloving.
Shearing.
Puncture: Bite.
Number of days of proliferation.
4-12.
All persons entering the OP room must be appropriately clothed. Name the correct option.
Hair covering, masks, shoe covers, gowns and gloves.
What is the recommended method for sterilization for endoscopic and arthroscopic equipment?
Ethylene oxid.
Which option is NOT correct?
Aseptic surgical techniques describe several types of surgical wound contamination.
Correct options:
- Antisepsis is process of removal of pathogenic organism from skin or mucous membranes but with some resident flora remaining.
- Antiseptics are agents used in the process of antisepsis: Any inhibits bacterial growth.
- Biocide and germicidal agents kill bacteria and other microorganisms outright.
Which type of injections are indicated in emergency situations?
According to the physical status rating the patient with pneumonia, fever belongs to the category:
Severe systemic disease.
Suture selection for different tissue types can be classified as:
Their behaviour in tissue:
- Absorbable: Surgical gut, loose most of their tensile Strength within 60 days.
- Non-absorbable: Split into organic, silk and metallic.
Their structure:
- Monofilament: Single strand of material.
- Multifilament: Several strands of suture, braided/twisted together → More flexible but may harbor bacteria.
Their origin:
- Synthetic: Strong, minimal tissue reaction.
- Organic: SiIk - used in vascular grafts.
Metallic: Knot ends evoke an inflammatory reaction, can cut tissue and migrate.
Ideal ventilation and temperature for operating theatre is?
Ventilation producing 20 air changes/hour.
Temperature 20-21°C, for pediatric patients 24°C.
