  1. Dr Jameelmiro Suture material what to choose how to handle

  2. Suture Characteristics • Tensile Strength • Related to suture size (see below) • Related to weight required to break a suture • Knot strength • Force required for a knot to slip • Configuration • Monofilament (less risk of infection) • Braided multifilament (easier to handle and tie) • Elasticity • Degree suture stretches and return to original length • Memory or suture stiffness • High memory: Suture stiff, difficult handling, unties • Tissue reactivity (inflammatory response to suture) • Reaction peaks in first 2 to 7 days

  3. Ideal suture material • The ideal suture material should • Have good handling characteristics • Not induce a significant tissue reaction • Allow secure knots • Have adequate tensile strength • Not cut through tissue • Be sterile • Be non-electrolytic • Be non-allergenic • Cheap and sterile

  4. Choice of a suture • Choice of suture depends on: • Properties of suture material • Absorption rate • Handling characteristics and knotting properties • Size of suture • Type of needle

  5. Classification of Sutures

  6. Advantages Broken down by body No foreign body left Disadvantages Consideration of wound support time Absorbable

  7. Advantages Permanent wound Support Disadvantages Foreign body left Suture removal can be costly and inconvenient Sinus & Extrusion if left in place Non - Absorbable

  8. ETHICON Absorbable Sutures Wound Support Mass Absorption Typical Uses • Skin • Perineum • Orals VICRYL* rapide 10 days By 42 days • Ligature • Mucosa • Obstetrics • Bowel • Skin 20 days 90 - 120 days MONOCRYL* • Ligature • General • Bowel • Ophthalmic Coated VICRYL* 30 days 56 - 70 days Coated VICRYL* Plus Antibacterial Suture • Ligature • General • Bowel • Orthopaedics 30 days 56 - 70 days • Traumatology • Ligaments • Fascia • Vessel anastomosis 60 days 180 - 210 days PDS* II

  9. Anatomy of a Surgical Needle

  10. Use of Needle Holders Loading Needle Needle passing through skin

  11. Needle Shapes • Nasal cavity • Nerve • Skin • Tendon • Eye • Microsurgery • Dura • Eye • Fascia • Nerve • Eye (Anterior • segment) • Muscle • Eye • Skin • Peritoneum • Laparoscopy • Cardiovascular • Oral • Pelvis • Urogenital tract

  12. Round Bodied Needles • TAPERPOINT

  13. Cutting Needles • Conventional Cutting • Reverse Cutting • PRIME • P Needle

  14. Packaging… Imperial Gauge Product (re-order) Code Metric Gauge Needle size & curvature Needle type Needle point Needle profile Batch Number Do Not Re-use Sterilised Ethylene Oxide Expiry date See Instructions foruse
