Surgical suture techniques

Suture techniques:

-All suturing techniques aim at bring wound edges together without gaps or tension. Interval between suture bites should be equal in length and proportion to size of tissues brought together.
-Minimal size and necessary amount of suture needed to close the wound should be used, because suture are foreign body.

types of suture materials.

• Non-absorbable - usually used when possible. Braided suture are not ideal for contaminated wound.
• Absorbable suture- commonly used when the patient are not able to return or during suturing internal structures or used in children for whom suture removal may difficult. This type of suture loses tensile strength within 60 days.

Common Practical suture Techniques:

• interrupted sutures- commonly used to repair lacerated wound and used in wound with  minimal skin tension. Bites are equal in volume and all good eversion of wound edges. Non-absorbable suture is used when possible. 
• continuous/running sutures- not time consume during suturing, few knots tied and less material used. Complication of this techniques include poor cosmetic result compared to other options and epidermal skin cell growing along suture track.
• continuous subcuticular sutures- excellent cosmetic result and useful in wound with strong skin tension especially in patient prone to keloid formation.
• mattress sutures- more complex and there time consuming. Its provide the relief of wound tension and provide precise wound edge apposition. Vertical and Horizontal are the two types of mattress suturing techniques.
• purse string sutures- done in a circular pattern that draws tissue together in a path of suture. Used particularly around the drain sites.
