When are retention sutures used?
Retention sutures are heavy gauge percutaneous sutures, usually with some form of skin protection, used in high tension wound closures to support primary wound closure. Typically, the term “retention suture” has been used in the general surgical literature to discuss closure of open and/or complex laparotomy wounds.
Which type of suture is often used to create a vascular anastomosis?
Polyglactin Sutures Like the Poliglecaprone suture, this suture too is used in of vascular anastomosis procedures.
What are Vicryl sutures?
VICRYL Suture is a synthetic absorbable suture coated with a lactide and glycolide copolymer plus calcium stearate. 1. It is indicated for use in general soft tissue approximation and/or ligation, including ophthalmic procedures, but not cardiovascular or neurological tissues.
What is a bridge suture?
The suture bridge technique involves using the medial row of anchors placed at the humeral articular cartilage margin and tying the sutures in a mattress fashion ideally 10 to 12 mm medial to the lateral edge of the torn tendon to secure the cuff tissue.
Why are bumpers or bolsters used on retention sutures?
Retention sutures using two bolsters provide inherent mechanical advantages in approximating wound edges. As demonstrated in geometric terms, distribution of tension along a bolster maximizes closing force while at the same time reducing stress at the individual suture site.
What is the difference between Monocryl and Vicryl?
Monocryl has identical knot performance compared with Vicryl, similar performance to PDS, and lesser performance compared with Maxon. Monocryl has high initial breaking strength, being superior to chronic gut, Vicryl, and PDS. Monocryl loses 70% to 80% of its tensile strength at 1 and 2 weeks.
Is Vicryl Rapide braided?
Because Vicryl is slow-absorbing and often braided, its use is contraindicated in the closure of any cutaneous wound exposed to the air, as it draws moisture from the healing tissue to the skin and allows bacteria and irritants to migrate into the wound.
What is an Aberdeen knot?
The Aberdeen knot is an alternative knot used when ending a continuous suture line, most often for subcutaneous and intradermal closure. When used in subcutaneous closure, this knot allows the surgeon to continue directly to an intradermal closure without cutting the subcutaneous suture line.
