Broadly, sutures can be classified into absorbable or non-absorbable materials.They can be further sub-classified into synthetic or natural sutures, and monofilament or multifilament sutures.. in suture application, glycolic and lactic acid polymers are commercially used. First, sutures of biological origin, such as surgical gut (eg, plain and chromic gut), are gradually digested by intraoral enzymes.2 This suture material is made from an animal protein and can potentially induce an antigenic reaction. However, with synthetic both resorbable and nonabsorbable suture materials, a surgeon's knot must be used to prevent untimely knot untying4 (Figures 4a through 4c). Now customize the name of a clipboard to store your clips. The half-life has become the established criterion for distinguishing between absorbable suture materials. B-ANAESTHESIA IN CAESAREAN SECTION *General anaesthesia in emergency situations may complicate with inhalation There may be mass of Suture in the wound and zero tensile strength retention. When used properly, surgical sutures should hold flap edges in apposition until the wound has healed enough to withstand normal functional stresses. 1. First, it is nonabsorbable, so it must be removed, usually a week or so later when the patient is not numb. Conclusion. First, sutures of biological origin, such as surgical gut (eg, plain and chromic gut), are gradually digested by intraoral enzymes.2 This suture material is made from an animal protein and potentially can induce an antigenic reaction. What is a Suture ?? For instance, when using silk or chromic gut, or plain gut suture material, a slip surgical knot should be used.
