1
Q

surgeon’s knot

A

first throw passed through loop twice

creates friction, less slippage

bulkier, asymmetrical, less knot security

2
Q

ligation

A

use of suture and knots to occlude blood vessels

suture-chromic gut, silk, synthetic absorbable

more secure than hemostatic clips

more time consuming

3
Q

simple vessel ligature

A

square knot in crush from a hemostat

place several mm from cut end of vessel

3-4 throws

4
Q

double ligature

transfixation ligature

A

one simple ligature

one transfixing ligature-halsted or modified

transfixing prevents slippage

5
Q

tissue ligatures

A

used when vessels cannot be isolated

loosens when entrapped tissue dies

6
Q

vascular pedicle ligatures

A

three hemostatic forceps technique-ligature placed in crush

not good on very large pedicles

7
Q

modified miller’s knot

A
8
Q

interrupted sutures

A

precisely adjust tension

time consuming

suture separate

more foreign material

poor suture economy

fibrin forms seal

9
Q

continuous suture

A

cannot adjust tension

less time

break disrupts entire closure

less foreign material

better suture economy, better immediate seal

10
Q

interrupted cruciate

A

stronger than simple interrupted

resists tension

prevents eversion

11
Q

ford interlocking

A

great seal

LA-thoracotomy-fast

12
Q

continuous intradermal

A

used in place of skin sutures

modified horizontal mattress in dermis

saves time and suture

weaker than interrupted

13
Q

gambee

A

inverting

prevents eversion of mucosa

used for intestinal resection and anastomosis

14
Q

lembert

A

inverting

vertical mattress-like

interrupted or continuous

penetrates submucosa

does not enter lumen

15
Q

Cushing

A

horizontal mattress-like

penetrates submucosa-does not enter lumen

less inverting than lembert

16
Q

connell

A

horizontal mattress like

penetrates all layers

enters lumen-may wick bowel contents–>bacteria in abdomen

17
Q

double layer closure

A

closing large hollow viscera

layer 1-cushing

layer 2-continuous lembert

18
Q

vertical mattress

A

tension relieving

apposes or everts

resists tension well

19
Q

near and far

A

tension relieving

like vertical mattress

edge approximation-no tension on edge

excess tension–>inversion

far-far-near-near

far-near-near-far

20
Q

horizontal mattress

A

apposes or everts

resists tension less than vertical

can be stented

21
Q

locking loop

A

tendon suture

22
Q

triple loop pulley

A

tendon suture

difficult

one on left

23
Q

abdominal wall closure

A

linea alba/external rectus sheath-simple interrupted

SQ tissue-simple continuous

skin-simple interrupted or cruciate

24
Q

ovarian pedicle

A

modified miller’s knot

encircling ligature

transfixation ligature

25
Q

uterine body

A

transfixation vs stick ligature

encircling ligature

26
Q

testicular pedicle

A

modified miller’s knot

encircling ligature

transfixation ligature

SQ tissue-simple continuous or cruciates

skin-intradermal with buried knots

27
Q

buried suture

A

goal-suture ends deep to bury knot

first bite-deep to superfiicial

second bite-superficial to deep
