Sutures Flashcards
Absorbable suture characteristics
Undergoes degradation and loses tensile strength within 60 days
What is tensile strength
The force the suture strand can withstand before it breaks
What are nonabsorbable
Sutures that retain tensile strength for more than 60 days or permanent
Describe monofilament
Withstand contamination.. Stiffer because it has a better memory
What is memory
Tendency of a suture to return to its original packaged form
What is multifilament
Several strands braided or twisted together. More pliable and easy to tie. Stimulate tissue reaction
Describe the ideal suture material
Versatile Easy to handle Have high tensile strength No memory No tissue reaction
3 type of suture needle attachment
Closed eye
French eye
Swaged
3 types of suture needle
Conventional cutting needle
Reverse cutting needle
Taper needle
What impacts suture material choice
Nutritional status Inadequate blood supply Chronic disease Infection Drugs
What is the typical length of the suture ear
3 mm
What is the Length of the skin ear
10-15mm
What is the average distance from incised placement
Usually 5 mm
What is the distance between each suture
Depends on the amount of tension that will be exerted on the incision
What is the pro of. Interrupted sutures
It’s ok if a suture breaks. Can adjust tension at each suture
