In the history of health, suturing is one of the crucial factors. It is vital for the healing of the wound and the prevention of further infection. The main purpose of suturing is to keep the injured tissues together in place until they join. The sutures are classified into two main categories that are absorbable and non-absorbable. It is understood by the name that absorbable sutures are absorbed by the tissues that they are holding which make their removal unnecessary. The non-absorbable sutures are not absorbed and need to be removed. The absorbable and non-absorbable sutures are further classified into many categories. Polyamide nylon sutures non-absorbable are a type of sutures that is commonly used.

CHARACTERSTICS OF POLYAMIDE NYLON SUTURES:

  • It is a monofilament non-absorbable suture.
  • It is a 100% homopolymer.
  • It is a macromolecule that is composed of repeating units.
  • The repeating units of polyamide nylon sutures are linked together through amide bonds.
  • Synthesis of polyamide nylon sutures includes ring-opening polymerization of caprolactam that is a six-carbon compound.
  • These are available in various sizes as plain monofilament or braided microfilament.
  • Polyamide nylon sutures are composed of fibers possessing high tensile strength and elasticity.
  • Polyamide nylon sutures are highly resistant to wrinkles’ abrasions and chemicals such as acids and alkali.
  • The monofilament structure lacks capillary action so it does not support bacterial growth whereas the microfilament structure has high capillary action.
  • It has a uniform diameter and offers prolonged tensile strength that resists breakage. It does not degrade even in infected areas.
  • It is usually available in black or blue color that allows easy identification and better visibility while operating.
  • It has a smooth texture causing minimal tissue drag and trauma. Due to its ultra-smooth nature, the pain experienced is negligible.
  • It is used as a percutaneous suture because of its low reactivity in tissues.
  • It has excellent knot security.
  • In these sutures, capillarity is absent.

INDICATIONS OF POLYAMIDE NYLON SUTURES:

  • Plastic surgery
  • Gastrointestinal surgery
  • Gynecology
  • Obstetrics
  • Orthopedics
  • Ophthalmic surgery (eye surgery)
  • For close cutaneous wounds
  • Cardiovascular surgery (it is not recommended in the attachment of artificial prosthesis)
  • Microsurgeries
  • Dental surgery
  • Tendon or ligament repair.

CONTRAINDICATIONS OF POLYAMIDE NYLON SUTURES:

  • If the patient has a history of hypersensitivity.
  • In circulatory system
  • In the central nervous system
  • In the synovial cavity because of its sharp ends that may cause injury to tissues.

STORAGE OF POLYAMIDE NYLON SUTURES:

  • Re-using, re-sterilization and re-processing are not recommended.
  • It can be stored in dry conditions.
  • The shelf life is up to 5 years.
  • To maintain its superior performance, repeated and prolonged sterilization must be avoided.

Many companies are monofilament polyamide manufacturers and suppliers in India. The price of polyamide nylon sutures is usually 1500-3000 INR/dozen. These sutures are used by surgeons all over the world to perform surgeries. As the number of surgeries has increased over the years, there is a rapid growth in suture companies around the globe. To prevent any adverse effects these sutures should not be used after the expiration date. All the precautions and warnings must be kept in mind while using these sutures.
