2 Objectives Define the term suture as a noun and as a verb. List the specifications for suture material and describe the importance of each.Describe the suture selection process.
3 ObjectivesList and describe the ideal characteristics for suture material and surgical needles.Identify the types and sizes of suture material, provide examples of each, and describe the type of tissue usage appropriate for each type.
4 ObjectivesIdentify the types and sizes of surgical needles, provide examples of each, and describe the type of tissue usage appropriate for each type.Describe suture packaging, list the information found on the suture package, and explain its importance.
5 ObjectivesIdentify types of stapling and ligating devices and provide examples of when each may be utilized.
6 ObjectivesIdentify types of alternative wound closure materials, tissue adhesives, and tissue repair and replacement materials and provide examples of when each may be utilized.
9 Brief Suture History3000 BCE - Linen strips and animal sinew (tendon) were used to close wounds with needles made of bone600 BCE - Cotton, leather, horsehair, and bark fiber from trees was used to close wounds
10 Brief Suture HistoryLister (late 1800s) was the first to use a bacteriocide (carbolic acid) on sutureSuture manufacture and sterilization started in the early 20th CenturyFirst synthetic absorbable suture was produced in the 1960s
13 Specifications for Suture Material Must be sterile and sterile technique must be used when handlingUniform tensile strengthUniform sizeAppropriate diameter for tissue typeProvide knot securityCause minimal foreign body tissue reaction
14 Suture Selection Characteristics of the suture material Age Weight Allergy statusGeneral tissue conditionSurgical site diseaseComorbid condition(s)Surgeon preferenceSuture availabilityCostMentor influence
15 Ideal Suture Characteristics PliableEasy to tie secure knotsTensile strength (will not fray or break)Glide through tissue effortlesslyInertNonallergenicInexpensive
16 Tensile StrengthTensile strength of absorbable and non-absorbable sutures is critical both during and after surgical procedures. Breaking strength and elongation can be measured using either a "straight pull" test or a "knot pull" test.
