Flashcards in Hemostasis Deck (22):
1

How do we control low pressure bleeding from small vessels?

Applying pressure

2

Pressure as a form of hemostasis relies on?

Pressure long enough to form an effective clot

3

Is pressure a permanent fix on larger vessels?

No temporary

4

How do hemostatic forceps stop hemorrhage

Crushes vessels arresting hemorrhage and damaging vessel wall activating clotting factors

5

How do you orient the hemostats to clamp off small and large vessels?

Small point the tip towards the vessel
Large apply with convex surface facing end of the vessel

6

Are vascular clips and ligatures secure?

The most secure

7

What is the major disadvantage of clips and ligatures

foreign material being left int he body

8

2 advantages and one disadvantage to vascular clips

Rapid placement
good for poorly accessible locations

More likely to be dislodged during manipulation

9

Big strengths ligatures have

Multiple vessels and pedicles
increased security on even the largest of vessels

10

Big disadvantage of ligatures

Awkward and time consuming

11

If you are worried about slippage you should use what ligature?

Transfixation

12

Knot security decreases as suture size _______

increases

13

Cautery works well for arteries and veins of what size?

Arteries 1mm
veins 2mm

14

3 types of cautery

monopolar
bipolar
ligasure

15

Describe monopolar cautery use

Coagulates and cuts
apply directly to vessel or indirectly onto forceps
only use on dry tissue
only contact at point of coagulation to avoid tissue damage

16

bipolar cautery requires?

electrolyte fluid to conduct

17

Does bipolar or monopolar use more current

monopolarI

18

Improper use of cautery leads to?

Hemorrhage
burns
dalayed healing

19

Ligasure is a?

Bipolar vessel sealing device, adjusts its own current to seal vessels

20

Ligasure can be use don vessels how large?

7mm in diameer

21

2 good examples of places topical hemostatic agents can be used?

Cancellous bone oozing
liver biopsy hemorrhage

22

Before using topical hemostatic agents need to be sure that the wound is?

Very clean, the foam persists for years.
