10.14). Action: Cross them over each other in front of the tube and perform another throw. Sutures, or stitches, are a way to close an open wound to speed healing and usually to ensure the least possible amount of scarring. Gloves and safety glasses are recommended. Figure 10.7 Halsted suture pattern. Procedure: Surgical treatment of abscesses in rabbits Action: Knot the two ends together as described below. As a general rule when selecting suture material, consider the following: Remember that there are two throws in a square knot. Procedure: Dew claw removal in neonatal puppies Action: Tie a knot with the two ends after applying the appropriate tension. 1. 4. Action: Continue to place a line of interrupted vertical mattress sutures along the incision line so that each one helps to hold the piece of tubing in place (Fig. Figure 10.12 Ford interlocking sutures. Action: Place the next suture about 5 mm along the wound. • Use slowly absorbable materials in fascia or tendons – the rate of healing is slow and the tissue requires the support of the sutures for some time. B. Quilled suture (Fig. Repair and treatment of corneal ulcers – requires experience as the consequences of accidental misapplication could be disastrous, Closure of oral wounds following dental work. It is the weakest point in a line of sutures and if it is incorrectly tied it will come undone and lead to reopening of the wound, which at the very least will delay healing but most severely could lead to evisceration and other complications. Inverting suture patterns Lembert (interrupted or continuous) interrupted continuous 16. Each individual suture is placed separately with its own knot so failure of one suture does not result in failure of the entire line. US Patent References: 3611551: N/A: 1971-10-12 ... are schematic views of a segmented suture needle pattern 110, in which the suture 13 is inserted in the hollow portion. • Check that the tissue is correctly aligned within the stapler and that no other tissues are caught up before firing the stapler. Rationale: You can tie a full surgical knot if you want, but one throw is usually sufficient to anchor the tube. Interrupted cruciate suture – this is currently a popular type of suture formed by two linked simple sutures arranged as a figure-of-eight and tied with one knot (Fig. 3. Table 10.3 (A) Standard simple continuous suture pattern. Simple running suture. It is better to be proficient at a small range of suture patterns than to be bad at performing all of them. 1. Joseph L. Hudgens, RP Pasic. Action: Place a simple interrupted suture in the skin at a point close to the exit of the tube. Healing by this method may take days, weeks or even months depending on the wound. Rationale: This locks the previous suture in place. 2. Rationale: This will enable the purulent material to drain out more easily. Square knot – this is the most common type of knot and is used to anchor most suture patterns. Action: Holding the needle in needle holders, insert the needle through the serosa of the intestine on one side of the incision. (Reproduced with permission from Stephen Baines, Vicky Lipscomb and Tim Hutchinson: BSAVA Canine and Feline Surgical Principles, 2012, originally illustrated by Samantha J Elmhurst.) The knot should not be too tight unless it is used as part of a ligature for haemostasis. Over time this wastage becomes very expensive! Procedure: Horizontal mattress suture The type of knot (Fig. There may be a loss of feeling when using instruments, but once you are proficient you will learn to gauge the tension of each throw. material with the number 3 is much thicker than 3/0; 3/0 is thicker than 7/0). One strand is held with more upwards pressure, resulting in a knot that can slide easily to tighten or to loosen. Rationale: This is the beginning of the second throw. Action: Push the needle through the wall of the intestine right through to the mucosa and into the lumen and then return it through all the layers up to the serosal surface again (Fig. Rationale: This will create a seal as the hole is vacated. Rationale: This will prevent the introduction of new pathogens into the site. Look it up now!. Plain Gut resorption rate from 3 to 5 days. Use slowly absorbable materials in fascia or tendons – the rate of healing is slow and the tissue requires the support of the sutures for some time. 6. Continuous horizontal mattress sutures – start with a simple interrupted suture and then continue with linked sutures as described above (Fig. (B) Note how this inverts the tissues. Examples of needle holders (Fig. Action: The patient should be sent home with antibiotics, NSAID analgesics and, if necessary, an Elizabethan collar. Synthetic / non-synthetic or natural – natural materials tend to cause a considerable tissue reaction and catgut in particular cannot be depended upon to produce reliable knots so these materials are no longer recommended. 6. 3. 4. 6. Rationale: Left-handed surgeons should work in the opposite direction. Each staple must penetrate all the layers of the tissue. a stick). They are used to eliminate dead space and to relieve tension on the skin sutures. each side of the incision after that it is tied. Action: To finish the line, insert the needle back down into the tissue on the same side as it has just been brought out from and pass it across the incision to exit on the other side. Action: On the far side of the incision, place the other piece of tubing parallel to the incision and between the two entry points of the suture. 3. 2. • The type of suture material – multifilament suture materials tend to have better knot-holding ability than monofilament suture materials (Table 10.1). due to infection, movement between the edges or patient interference). Action: Using a sterile scalpel blade, make a stab incision into the skin overlying the abscess. Running (continuous) sutures provide an adequate closure with even tension distribution as … Tension on the tube increases as the tube is pulled, thus preventing its removal. positioned in some type of coordinate space. 10.12). 5. Warming the fluid reduces cold shock. Suture patterns can be classified as to: There are various types of stapler designed for internal use and for repairing skin wounds and the staples themselves come in different sizes. Rationale: This action locks the simple suture in place. The needle must not penetrate into the lumen and the suture bites are placed perpendicular to the incision as in the vertical mattress suture pattern. - Greater stability in the event of partial failure (failure of. Setting time varies between 2 and 60 seconds depending on the thickness of the glue layer, the amount of moisture and the chemical makeup of the adhesive. Never use staples in tissues that are inflamed, oedematous or necrotic. There are many types of suture material; the correct choice depends on the properties of the material, the nature of the wound, including the presence or absence of infection, the rate of healing of the tissue and the intended use of the suture. • Ligation of blood vessels Rationale: One end attached to the needle will be longer than the other end, which should be about 2–3 cm long. Rationale: The suture material will have entwined the tube in a net-like structure, which will hold it firmly in place (Fig. A modified Gambee is placed in the same way, but does not penetrate the lumen of the intestine. Action: Full aseptic technique must be observed. B. Quilled suture (Fig. 7. Action: Repeat this at least 5–6 times and terminate with a secure knot consisting of several throws. 10.3B). Procedure: Ford interlocking suture (Fig. If you insert the needle too close there will not be enough room to complete the manoeuvre correctly. This pattern uses up more suture material than other patterns. Absorbable or Non-absorbable 2. 5. The suture is started by burying the knot in the dermis (see later description) and the suture line lies intradermally. • Reduce by one size for delicate tissue and increase by one size for tough tissue. Subcutaneous sutures – these are placed in a simple continuous pattern below the skin and the bites of the suture lie vertical to the incision (Fig. The suture material has described a rectangle across the incision (Fig. You may add dilute chlorhexidine in a dilution of 1 : 40 if necessary. d. Provide an easy and secure method of closing tissues such as the lung, liver and gastrointestinal tract, large vessels and vascular pedicles. Procedure: Tying a square knot using instruments Chapter Contents • Avoid multifilament material in contaminated wounds – there is a risk of ‘wicking’ and the spaces between the strands may harbour blood, which will become a medium for bacterial growth. 3. Rationale: This will hold the tubing in place on the far side (Fig. Tissue heals quickly as it is not reliant on suture for much more than 14–21 days Rationale: This should result in the immediate release of purulent exudates, which may smell and may be blood-stained. Each individual suture is placed separately with its own knot so failure of one suture does not result in failure of the entire line. Useful in small species (e.g. Action: To finish the line, insert the needle back down into the tissue on the same side as it has just been brought out from and pass it across the incision to exit on the other side. The suture bites are parallel to the line of the incision. The suture is started by burying the knot in the dermis (see later description) and the suture line lies intradermally. 10.14). The tension applied to the knot is also important. To bury the knot, introduce the needle deep in the far subcutaneous or intradermal tissue passing it up into the tissue, across the incision and then down into the tissue on the near side (Fig. Placing a purse ring suture around the anal sphincter prevents the passage of faeces, which may contaminate the surgical site – do not forget to remove it! 2. You can use either vertical or horizontal mattress sutures. In this technique, your absorbable suture would be used to bury the knot at the lowest point of the wound. Suture patterns are typically categorised as: 1. continuous or interrupted 2. inverting, appositional, or everting 3. the effect the suture pattern has on wound tension.The choice of using interrupted versus continuous suture patterns still remainscontroversial. Closing biopsy wounds Action: Pull the suture material through leaving about 3 cm sticking out of the far side. The number of throws required to make a secure knot also varies with each suture material and pattern (interrupted vs continuous). 10.16) – this is similar to the square knot except that the first throw has the strand of suture material thrown over the needle holders twice before the short strand is pulled through. (Reproduced with permission from Stephen Baines, Vicky Lipscomb and Tim Hutchinson: BSAVA Canine and Feline Surgical Principles, 2012, originally illustrated by Samantha J Elmhurst.) 10.16). Rationale: This creates a stitch at right angles to the incision. Viscera Rationale: This is easiest to do using a curved needle. After Hoad 2006, p 106, Minor Veterinary Surgery with permission of Elsevier Butterworth-Heinemann. Rationale: Gently allow this throw to form the knot to prevent the suture tightening excessively. This will take place if first intention is impossible or has failed (e.g. 10.6). 3. in the bladder the suture may become a focus for deposition of crystals forming calculi). 3. The needle should be grasped by the tips of the needle holder at a point on the needle that is one-third to half of the way along the needle from the suture material end. Action: Cut two pieces of intravenous drip tubing to the approximate length of the incision. The disadvantages are the additional expense and the time taken to master the technique. Polyglactin 910: It is available in braided form. Commonly Used Suture Types in ED. b. Rationale: The knot must be secure to ensure that the whole line does not come undone. 5. Slip knot – this is the same as a square knot except that the tension is uneven. Rationale: The aim of the suture is to reduce eversion of the mucosa and reduce wicking of intestinal contents to the serosal surface. Rationale: This will allow sufficient space to place the mattress suture at right angles to the line of the incision (Fig. The knot should have a minimum number of throws. Wounds heal by: Simple Interrupted Suture. 40th Global Congress AAGL, 2011 2. Action: Leave both ends of the suture material long. *After Hoad 2006, p 106, Minor Veterinary Surgery with permission of Elsevier Butterworth-Heinemann. 5. 5. dogs and cats) swell significantly after surgery, so sutures must be placed loose enough to account for this. Action: Holding the needle with needle holders, insert the needle approximately 8–10 mm away from the edge of the incision on the far side (Fig. Sutures are used to close wounds … Rationale: Excessive tension and inversion of the suture line may delay healing and cause pain, which could lead to patient interference. Rationale: The gap between each knot should be about 0.5–1 cm. If the tissue is delicate you hold the needle closer to the suture material end, and closer to the point for tougher tissues. 10.12). Box 10.1 outlines the factors to be considered in the use of surgical staples. Action: The wound should dry up and heal within a few days. Tumbled knots, half-hitches and granny knots are incorrect and may come undone. Procedure: Ford interlocking suture Rationale: An Elizabethan collar may be necessary to prevent patient interference, but be careful if the abscess is around the neck area as the collar will rub. renal artery or vein) Figure 10.7 Halsted suture pattern. 1. 10.10A). Figure 10.11 Suture patterns: (A) subcutaneous; (B) intradermal. 10.10A). The tension on the throw should slightly indent the tube, but must not be so tight that it occludes the lumen of the tube. There should be very little evidence of scarring. Size of suture material – there are two systems in use: the metric system and the United States Pharmacopoeia  / European Pharmacopoeia system (USP / PhEur). Absorbable vs Non-Absorbable. Procedure: Treatment of an aural haematoma Rationale: This will create a seal as the hole is vacated. The types of material (Table 10.1) can be broadly divided into: 10.16). Rationale: A small percentage of abscesses return and will have to be redrained.< div class='tao-gold-member'> Action: Keep your hands low and parallel to prevent the knot tumbling. It can be time consuming to remove as each loop must be cut individually to avoid pulling suture material that has been exposed to the external environment through the inner tissues of the wound. Rationale: The body should not be able to tip over or slip during the procedure and may be secured using tapes or other forms of support. It is the copolymer of glycolic acid and lactic acid and it is coated with calcium stearate. Running simple continuous sutures (Fig. suturing of specific organs such as tendon which usually, Each suture in this technique is individually tied and cut ; each, Presence of additional suture materials within tissue in, edge apposition with slight eversion of edges when the, Usually is used in tissues that required minimal holding also, Used for closure of subcutaneous tissue and fascia in non-tension, areas because it is undesirable for wound that are under, parts so knot slippage or break is likely to cause failure of, knot is not necessarily result in failure of the entire suture, This technique is used to eliminate scars formation in, tissue especially the skin so it is usually used in cosmetic. 10.2) include Gillies (which also provides a scissor action but no ratchet), Olsen-Hegar (which has a ratchet and scissor action) and McPhails (which has a spring ratchet). Dew claws b. • Surgeon’s preference. Perhaps the biggest advantage of continuous suture patterns is 54 Rationale: This action locks the simple suture in place. Abscesses are relatively rare in dogs, but do occur in rabbits. Action: Bring the needle up on the opposite side 2–5 mm away from the tissue edge (Fig. Rationale: This type of suture can be used in areas of tension as the pressure exerted by the horizontal sutures is spread evenly over a broad area, which reduces the likelihood of tearing through the tissue edges. • Suture pattern Action: Cross them over each other behind the tube and perform a throw again. 4. 5. Disadvantages: Time consuming to place. Remove by cutting both loops so that you avoid dragging pieces of the suture that have been exposed to the external environment through the tissues. This is usually at 10–14 days, but healing may take longer in debilitated patients or if there has been patient interference. Examples of needle holders (Fig. *Adapted from Manual of Canine and Feline Surgical Principles. Interrupted - each stitch is cut and tied as a separate entity : Advantages: Allow precise adjustment of tension along the length of wound. Do not use tissue adhesive on infected wounds, deep puncture wounds or if the edges are under tension. Resorbable sutures, such as polyglactin 910, do not pose this problem as they will be digested along with the meat. If you insert the needle too close there will not be enough room to complete the manoeuvre correctly. • Avoid reactive materials in the creation of stoma. Rationale: Monofilament suture material will not ‘wick’ up the infection. Interrupted suture patterns. Rationale: This creates a stitch at right angles to the incision. 10.3A). Common surgical procedures 2. 1. Action: Holding the needle in needle holders, insert the needle through the serosa of the intestine on one side of the incision. • Never use staples in tissues that are inflamed, oedematous or necrotic. (With permission from Baines S, Lipscomb V and Hutchinson T (2012) Manual of Canine and Feline Surgical Principles. Action: Place a simple interrupted suture and leave the two ends of suture material free. • Avoid burying any suture material from a multi-use cassette – there may be a risk of contamination from previous use. ResearchGate has not been able to resolve any citations for this publication. Action: The wound should dry up and heal within a few days. Absorbable suture material should be used. More knots, therefore more suture material left in wound. 10.10). Rationale: These ends will allow you to wind them along the length of the tube. 2. 27 Horizontal mattress sutures, because of their configuration, may result in ischemia of the tissue within its suture loop, which may compromise subsequent efforts, if necessary, to reconstruct the defect. Action: Keep your hands low and parallel to prevent the knot tumbling. Select from premium Suture Patterns of the highest quality. Sutures to be placed internally would require re-opening if they were to be removed. Continuous sutures are much quicker to do, but if one of the knots comes undone the entire line unravels. Rationale: You have now formed the first throw. Action: Insert the needle into the skin perpendicular to the incision and at an appropriate distance from the first suture. Action: If partial closure is performed, use absorbable monofilament suture material. Their brands are discussed in this post, but the same principles should apply to other brands; Brand Name Material Strength Retention Full Absorption Applications; Absorbable: Multifilament : Vicryl: Polygalactin 910: 50% at 21d: 56-70d: … If they are too far away from the edge, too great a thickness of tissue will be pulled up and may invert. Intradermal sutures – these are often used to replace skin sutures and to reduce scarring. 10.14) – A quill is material such as a piece of rolled gauze or a piece of tubing from an old giving set that is used to distribute the tension of a suture over a greater surface area. Gentle bathing will clean away the exudates, but should not be necessary after the second day as the wound dries and heals. If the ends are crossed incorrectly a granny knot will form (Fig. 10.11A). Procedure: Castration in the mature cat Interrupted: Provide more security from suture breakage. If it is applied to skin there is slightly difficult to remove. Procedure: Ovariohysterectomy in the doe It apposes the tissue more effectively than a simple interrupted pattern and distributes the tension better. (Reproduced with permission from Stephen Baines, Vicky Lipscomb and Tim Hutchinson: BSAVA Canine and Feline Surgical Principles, 2012, originally illustrated by Samantha J Elmhurst.) Monofilament Only gold members can continue reading. Specialized suture techniques Tissue adhesives – these are cyanoacrylate monomers that become strong insoluble polymers on contact with the water on tissue surfaces. 7. 4). Another excellent way to learn and become practically proficient is the use of cadavers, although you should consider the moral and ethical issues associated with this. Action: Take the needle across the incision and bring it up through the tissue on the opposite side. Rationale: Do not knot the suture. Department of Veterinary Clinical Medicine, College of Veterinary Medicine, University of Illinois, Urbana, Illinois. Action: Holding the needle with needle holders, insert it into the tissue on the far side of the incision about 2–5 mm away from the edge. Hold the suture in your non-dominant hand and the needle holder in your dominant hand. suture pattern, except that the continuous pattern had significantly lower skin disruption scores. Rationale: This is the beginning of the second throw. Pass across the incision and bring the needle up on the near side (Fig. Figure 10.5 Horizontal mattress suture pattern. A wide range of suture materials, patterns and sizes were used for the procedures included in the survey, clearly demonstrating the variable opinions of veterinary surgeons. It may also be used to close a hole in the thoracic wall after penetration by a foreign body (e.g. Quickly memorize the terms, phrases and much more. Absorbable of long duration / non-absorbable. Suturing Techniques 1. Gastrointestinal foreign bodies Action: Tie a knot with the two ends of the suture material. 3. Rationale: The short end is the end without the needle. E. Not applicable to my practice. Examples of scissors, needle holders and forceps. Reduce by one size for delicate tissue and increase by one size for tough tissue. Part 3 - Classification of sutures Lab 4 . Surgical staples – these cause little or no tissue reaction and they provide excellent tissue apposition and haemostasis. 1. Intradermal sutures – these are often used to replace skin sutures and to reduce scarring. Following removal of the sutures after cooking, the skin staples had significantly better skin disruption and cosmetic scores. The list of procedures has been arranged in alphabetical order. 4. P≤.05 was considered significant. If you leave a long piece of suture material it will be wasted when you cut it off. Action: Continue to place a line of interrupted vertical mattress sutures along the incision line so that each one helps to hold the piece of tubing in place (Fig. This produces an interrupted pattern in which the edges of the wound are inverted. Reduction in tissue handling and trauma, c. Reduction or elimination of contamination by intestinal contents. • The way in which the tissues are apposed: Basic Suture Patterns, Classification, suture patterns, Interrupted, Continuous, Inverting suture patterns Lembert (interrupted or continuous). Available in two types: a. 10.6). 8. iii) Figure 10.17 To bury a knot to start subcutaneous or intradermal sutures. … Pulling the suture tight will hold the tubing in place. Rationale: You can use two pieces of rolled up gauze instead of tubing. 3. Action: Turn the needle around and insert it on the same side, but at a point approximately 4 mm from the edge. Pulling the suture tight will hold the tubing in place. Cram.com makes it easy to get the grade you want! 10.13) – This technique may be used to close visceral stumps and to secure percutaneous tubes into a viscus such as may be seen in gastrostomy and cystostomy procedures. Rationale: To prevent it interfering with the healing process and then being difficult to remove from the tissue. Action: Insert the needle approximately 8–10 mm away from the edge of the incision on the far side. d. Provide an easy and secure method of closing tissues such as the lung, liver and gastrointestinal tract, large vessels and vascular pedicles. This suture is placed by inserting the needle perpendicular to the epidermis, traversing the epidermis and the full thickness of the dermis, and exiting perpendicular to the epidermis on the opposite side of the wound. Look it up now!. Rationale: Do not pull so tight that the edges evert. You can use either vertical or horizontal mattress sutures. Gentle bathing will clean away the exudates, but should not be necessary after the second day as the wound dries and heals. Warming the fluid reduces cold shock. Hands should be on the same level – if one hand is lifted the suture will tumble and form a sliding two-half-hitch knot.
