Test 2: surgical drains

Question 1

Implants designed to facilitate removal of fluid or gases
out of the body

Answer 1

surgical drain

Question 2

surgical drains are used for

Answer 2

eliminate dead space

evacuate excessive fluid or air

prevent accumulation of fluid or air

Question 3

— is used for passive drains

Answer 3

latex
PVC
silicone
silastic

Question 4

flat drains depend of — and —

Answer 4

gravity and capillary action

penrose drain

Question 5

— will cause fluid to exits around the outside of the drain

Answer 5

flat drain- penrose

Question 6

disadvantages of flat drain

Answer 6

Ascending bacterial infection, passive drainage only, gravity dependent, latex

Question 7

tube drains can be used —

Answer 7

open and closed system
passive or active

have single or multiple lumens

Question 8

advantages of tube drains

Answer 8

Easy to create closed system, measure volume of
fluid, decreased risk of ascending infection

Question 9

disadvantages of tube drains

Answer 9

Firm tubes can be irritating and painful, prone to clogging when used passively

Question 10

sump drains work by

Answer 10

double lumen

Smaller outer lumen = Ingress of air

Larger inner lumen = Egress of fluid

Sump Drains: Open suction

Question 11

— are dependent on gravity and capillary action with drainage related to surface area

Answer 11

open drains: flat or tube drains

Advantages * Help obliterate dead space and facilitate removal of
fluid

Disadvantages * Ascending bacterial infection, passive drainage only,
gravity dependent

Question 12

Answer 12

jackson-pratt

Question 13

advantages of closed drain

Answer 13

Drain from within lumen, passive or active drainage, drain into closed collection system

Question 14

disadvantages of passive drains

Answer 14

Gravity dependent so need to consider location, less efficient fluid evacuation

Question 15

active drains are maintained under—

Answer 15

negative pressure

continuous or intermittent suction

Question 16

advantages of active drain

Answer 16

Efficient fluid removal, decreases risk of ascending
bacterial infections, allows monitoring of fluid
volume, not gravity dependent (placed anywhere)

Question 17

disadvantages of active drain

Answer 17

Can be difficult to maintain suction, tissues can clog
drain, high negative pressure (>80mmHg) can
damage tissues

Question 18

—- drain is a tube with compressible bulb that applies negative pressure

Answer 18

jackson pratt drain

Question 19

Fenestrated tube attached to a suction device

Answer 19

hemovac drain

Question 20

wound vac also called

Answer 20

negative pressure wound therapy

applies negative pressure- continuously or intermittently

Question 21

Thoracic drain tunneled under skin and then inserted
through an intercostal space at — aspect of rib

Answer 21

cranial

Question 22

why cant your have open system drain in chest

Answer 22

needs negative pressure to inflate lungs

Question 23

Heimlich Valve

Answer 23

Allows air to exit during expiration and collapsible rubber latex prevents air from entering during inspiration

Question 24

abdominal drains are passive or active

Answer 24

can be both

be carful not to suction intestines accidentally

closed system

Question 25

when to use open peritoneal drainage

Answer 25

Only in small animal
Severe septic peritonitis

Minimal risk of clot formation impeding drainage

Question 26

when to remove drain

Answer 26

<2-4 ml/kg/day

remove as soon as possible

Abrupt decrease in fluid
and change in character of fluid

Question 27

what are some complications of drains

Answer 27

Poor drain placement
Ascending infection
Foreign body reaction
Loss of function
Fluid accumulation
Clogging, loss of suction
Be very cautious back-flushing
Penetration of organ
Incisional dehiscence
Discomfort / pain
Inadvertent removal
