This Concept Map, created with IHMC CmapTools, has information related to: suture techniques 2, Aberdeen Disadvantages 1. Because this knot is of low strength, it is used only for closing skin where forces are minimal. 2. Knots formed with less than 3 throws performed poorly as they were able to slip easily. 3. Knots made with more than 3 turns were more difficult to snug down and would be loose, introducing significant slack as the suture line is tightened., One handed tie Advantages 1. Quick and consistent tying method. 2. Useful for hard to reach areas. 3. Handy to use when there is no needle driver., Suture Techniques includes Far-near-near-far, Aberdeen Advantages 1. Stronger and more secure than a Surgeon's knot when ending suture line. 2. Uses less thread than a contemporary Surgeon's knot. 3. According to researchers, a configuration of 3 throws annd 2 turns keeps the knot in place, preventing slipping., Utrecht Advantages 1. Inverts suture pattern into organ cavity thus limiting the chance of an inflammatory reaction. 2. Minimal adhesion formation following surgery which is still secure, making it less likely for uterine fluids to leak during contraction and involution of the uterus. 3. A single layer should be suffuicient enough if the uterine wall is healthy and its contents are not septic., Far-near-near-far Disadvantages 1. Excess pulling on the knot will create more eversion of the near edges, producing excess tension and scarring. 2. If tied too tightly, necrosis can occur under the skin. 3. Suturing technique cannot be used on cosmetically sensitive areas (eg. face) as they are known to leave "railroad marks"., Ford Interlocking Disadvantages 1. Requires a lot of suture material which may be difficult to remove. 2. Difficult to remove and may cause pressure necrosis. 3. It can be embedded in tissue when placed in tension., One handed tie Procedure View video, Suture Techniques includes Utrecht, Knot and Ligature Techniques Includes Aberdeen, Far-near-near-far Advantages 1. This suture technique can serve as effective initial sutures to hold skin flaps in place. 2. Better technique for holding fragile skin together such as on an elderly animal. 3. Allows for precise control of suture material onto skin., Utrecht Procedure View video, Ford Interlocking Procedure View video, Aberdeen Procedure View Video, Suture Techniques includes Ford Interlocking, Utrecht Disadvantages 1. if the knot isn't buried properly, material will remain exposed and lead to adherance to other surrounding organs 2. Retension can occur, Knot and Ligature Techniques Includes Strangle knot, Ford Interlocking Advantages 1.Better apposition than Simple Interrupted. 2. Produces both airtight and watertight closure. 3. 'Locking' the suture patten at the end of the procedure ensures that the suture is less likely to unravel when patient moves., Strangle knot Advantages 1. Can be used to create a tourniquet or bind a broken limb due to its great strength. 2. When tied it tightens up so well on itself that it becomes hard to untie. 3. Knot does not bind prematurely, One handed tie Disadvantages 1. Can be time consuming durimg surgery for inexperienced surgeons who may not be familiar with technique. 2. Upward pressure should be avoided when tying knot to prevent tearing of tissue.
