Suture breakdown ● Thread used to close up tissues (bring together) ● Securing medical device + ligate vessels ○ Needles attached (swaged) ○ Tie = thread without needle ■ Used for ligation ● Material compositions ○ Silk ■ Tissue reactivity ■ Limit in use = especially not in face ○ Cat gut ■ Collagen from ovine serosa ■ Will be absorbed into human body after 7-14 days after suture ○ Chronic gut ■ Longer duration ■ Often treated with chromic salts ○ Synthetic = most common ■ Biologically inert ● Prolene ○ Strong, non-absorbable ○ Used in cardiovascular implant ○ Fascial closure ● PDS ○ absorbable , long support (240 days) ○ Facial closures ● Vicryl ○ Mid absorptions (56-90 days) ○ GI ○ Anastomoses ○ Subcutaneous surgery closures ● Monocryl ○ Fast absorptions (10-14 days) ○ Soft tissues ● Nylon ○ Nonabsorbable ○ Cardiovascular works Tissue/Use Preferred Suture Skin closure Nylon, Prolene, Monocryl Fascia PDS, Prolene GI anastomosis Vicryl, Polysorb, absorbables Cardiovascular Prolene, Nylon Subcutaneous tissue Vicryl, absorbables Vessel ligation Silk ties Naming ● Called by (Size) + (material) + needle ● Here it is 2-0 Vicryl on cutting needle ○ 2-0 silk tie Absorbance ● Broken down in body through enzymatic and hydrolysis ● There also is non absorbable which will remain in body indefinitely unless it is removed Sutures must be chose by tissue types, healing time, cosmetic needs (if facial) and risk of infections Size and diameters ● #4, #3, #2, #1, 0 ,2-0, 3-0, 4-0 ,.... 12-0 ● Smaller the number the thicker the suture becomes ○ #2 is larger than 3-0 ■ 0.6mm vs 0.2mm ○ 6-0 and smaller is used for precise work such as eye, and microvascular sutures
