absorbable suture material

Vicryl (polygalactin 910), chromic gut) Degraded in tissue in less than 60 days; Traditionally used for closure of subcutaneous tissues or injuries to the tongue or nailbed; Non-absorbable (e.g. ‘Medical applications of poly-4-hydroxybutyrate: a strong flexible absorbable biomaterial’. Common suture materials and suggested indications for their use Table of when to use different types of sutures Examples Synthetic or Natural Suggested Indications Absorbable Monofilament CatgutChromic Catgut Natural Rarely used PDS™ (Polydioxanone)Monocryl™ (Polycaprone Glycolide) Maxon™ (Polyglyconate) Synthetic Buried dermal sutures or continuous subcuticular suture Absorbable … Some body fluids are very slightly alkaline. Chu, in Biotextiles as Medical Implants, 2013. TENSILE STRENGTH. A hemorrhage involving the levator muscle will compromise elevating function. Synthetic nonabsorbable sutures may be made of polypropylene, polyester, polyethylene terephthalate, polybutylene terephthalate, polyamide, different proprietary nylons, or Goretex. They concluded that it was the physical structure of a suture that controlled the amount of bacteria that the material attracted. It breaks down and is absorbed within 7 to 10 days. Stitches which dissolve in body fluids to produce harmless products have been known for many years, the polymers of interest producing non-toxic monomers or starting units. The two sets of barbs divide the suture into two sections, right and left. Even a photograph of a failed product is better than no product at all, for much can be learnt from good photographs of failures. One of the lengths was strained to break on a tensometer, by tying a granny knot to form a loop and then stringing the loop over round supports on the machine. 13-24). For example, the 50% porous P4HB film took 56 weeks for in vivo subcutaneous degradation in rats. Biochemical Engineering Journal 16 (2003), 97–105. Absorbable Sutures Plain Gut and Chromic Gut This material consists primarily of collagen, which is absorbed by the body. Use of fermentation is an advantage not only due to high yields (up to 50 g/L), but also because it allows additional options for tailoring properties by incorporating other co-monomers and the ability to vary molecular weight. However, silk is still popular in ocular, neural, and cardiovascular surgery owing to its advantageous characteristics. Another unique physical configuration that is available in polyamide sutures and has the trade name Supramid Extra®, has core-sheath design: a twisted Nylon 6,6 core covered by a Nylon 6 jacket. Evidence from the staff involved in the original stitching was contradictory, but it was known that very junior staff had been involved when the patient was stitched. In the USP standard, which is used most commonly, the size is represented by a series combination of two Arabic numbers: a zero and any number other than zero, for example, 2–0 (or 2/0). An ultrasound scan showed her uterus distended with blood clots, about 1 litre being removed under general anaesthetic via her cervix. Wounds within the bounds of the oral cavity tend to heal rapidly and do not require prolonged suture support. Table 11.4. A newer, effective absorbable suture is poliglecaprone (Monocryl).11 This suture material has a high initial tensile strength and low tissue reactivity. Abbreviations: DL-PLA, copolymer of p- and L-Lactide; P3HB, poly-3-hydroxybutyrate; PCL, polycaprolactone. Scanning electron images of some commercial nonabsorbable sutures (a) Silk: polyester family; (b) Mersilene; (c) Novafil: polyamide family; (d) Nurolon; (e) Ethilon; (f) Dermalon; (g) Supramid: polypropylene family; (h) Prolene: polyvinylidene fluoride family; (i) Pronova: oly (ether ester) family; (j) Dyloc: poly(tetrafluoroethylene) family; (k) Gore-Tex (l) Stainless steel. A Mrs P was recovering after successful delivery of a baby boy, using an emergency Caesarean section. P4HB appears to degrade more slowly than PGA, but faster than PLLA, polycaprolactone (PCL), and other polyhydroxyalkanoates like poly-3-hydroxybutyrate (P3HB) in a subcutaneous environment (Table 11.3). Examples of Absorbable sutures are: Catgut, Polydioxanone (PDS), Polyglactin (Vicryl) and Polyglycolic acid. The major distinguishing factor between P4HB and typical sutures is the handling during the wound closure process. G. Thilagavathi, S. Viju, in Advances in Silk Science and Technology, 2015, Silk is a natural non-absorbable suture material that has been widely used for wound ligation; it was the most common natural suture, surpassing collagen, used in the biomedical industry during the past 100 years. The monofilament sutures contain up to 78 barbs manufactured in a spiral pattern around the circumference of the suture. Table 10.A.2 in the Appendix at the end of this chapter outlines USP and EP suture size classification. The barbs are divided into two groups facing each other in opposing directions around the mid-point (Figure 15.8). A newer form of this suture is gut treated with chromium trioxide (chromic gut) to retard absorption in tissues; however, its holding security is only 14 days. Absorbable Sutures. Fiber diameter approximately 0.25 mm, representative of a 2/0 suture. P4HB has Tg close to PCL, one of the lowest in the absorbable polymer category. In terms of the physical configuration of the threads, sutures can also be classified into: Suture materials made of nylon, polyester and stainless steel are available in both multifilament and monofilament forms. Appendix 2 at the end of this chapter provides a summary of these. Fiber diameter approximately 0.25 mm, representative of a 2/0 suture. Comparisons of properties of P4HB with other synthetic absorbable aliphatic polyesters. The main reason for using the nail as a splint is to prevent adhesions and granulation tissue buildup between the eponychium and the germinal matrix of the bed. Kent Petrie MD, ... Walter L. Larimore MD, in, Family Medicine Obstetrics (Third Edition), Polyglycolic acid (PGA) (Dexon) currently is in widespread use as an, The Breast, 2-Volume Set, Expert Consult Online and Print (Fourth Edition), After the diseased portion of the duct is removed, the nipple is carefully reconstructed with no. The suture can be placed, and because of rapid absorption, no return visit is necessary for removal. A newer form of this suture is gut treated with chromium trioxide to retard absorption in tissues. The anterior outer row is the last completed. To maintain the nail in place, two 5-0 nonabsorbable sutures can be placed through trephined holes (see Fig. A gradual reduction in strength is optimal for wound closure and healing as it allows a wound the time to accommodate changes as they occur. They are used primarily as buried sutures to close the dermis and subcutaneous tissue and reduce wound tension. Table 11.3 shows the mechanical properties of P4HB in comparison to current synthetic absorbable biomaterials (Martin and Williams, 2003). Its major advantage is that it can be used for skin closure without the need for removal. Absorbable synthetic sutures are composed of chemical polymers that are absorbed by hydrolysis and cause a lesser degree of tissue reaction after placement. C.C. Dr Ruff took the idea of a barbed suture and applied it to an absorbable suture material made of polydioxanone. 4HB, polymerized with other hydroxy acids such as 3-hydroxybutyrate (3HB), can yield elastomeric compositions at moderate 4HB contents (20–35%), and relatively hard rigid polyesters at lower 4HB contents (see Table 11.2) (Martin and Williams, 2003; Doi, 1990). For example, Blomstedt and Osterberg (1978) observed that surgical infection rates were higher for multifilament sutures due to high capillary capacity than for noncapillary monofilament sutures. Studies have shown that TephaFLEX is both biocompatible and noninflammatory. Imported materials: Absorbable surgical suture is imported and processed from the world's largest chemical synthetic suture raw material supplier. The unique ability of the polymer to be elongated almost ten times its original length is due to the orientation of the polymer chains, resulting in exceptionally strong fibers. Since the sutures failed the day after they were emplaced, it was thus unlikely that they failed by dissolution in her body. The amount of time this takes depends on the material, but also the location of insertion and the individual patient characteristics. The plane chosen is either the dermis or just deep to the dermis in the superficial subcutaneous fascia. The production of P4HB is performed through a proprietary transgenic fermentation process in the bacteria Escherichia coli, a microorganism that has become the workhorse of the biopharmaceutical industry. 4-0 absorbable suture material. An interrupted inverting seromuscular technique can also be used for small bowel, colon, or colorectal anastomoses, with silk, polyglycolic acid (Vicryl), or polyglycolitic acid (Dexon), size 3-0 or 4-0 (Figure 177-3). The mechanical changes induced by absorption are not abrupt, but rather gradual in P4HB, unlike those found in other synthetic absorbable polymers such as PGA. The relatively higher resistance to infection of chromic and iodized catgut sutures, compared to plain catgut sutures, further demonstrates this relationship between infection and inflammation. Other materials include artificial fibers such as polypropylene, polyester or nylon, which may have special coatings to make them more efficient. Polyglactin-910 can be modified by irradiation, which greatly increases its tissue absorption.6 This quality makes polyglactin-910 ideal for closure of oral mucosa, scrotal skin, scalp, and perineum. The Roman physician Galen described the use of absorbable suture, specifically catgut, in 175 A. D. 2 Sterile suture material was formally introduced by Lister in 1869 by treating catgut with chromic acid. However, it may leave patients uncompensated, and product manufacturers uncertain of the state of their product. One can either use absorbable or non-absorbable sutures when placing subcuticular sutures. Source: Data adapted from Martin, David P and Simon F. Williams. Closure can be delayed up to 2 weeks with good long-term results.12. It is unusual for cords to break centrally, fractures tending to occur at knots or other attachment points, as experiment had shown. It has the potential to be stretched up to 1000%, or ten times its original length before breaking. The material may not be completely absorbed at this point, but it will have lost the majority of its initial tensile strength. Chromic catgut is a natural absorbable suture material. POLYGLACTIN 90%. If the choice is a thin Nylon suture remember to remove the suture within 5 days to avoid having to dissect out fragments of suture material from the semi-healed wound margin. Absorbable sutures (e.g. Dissolvable (absorbable) stitches (sutures) are used to close wounds or surgical incisions, typically inside the body. ABSORPTION . Two tests gave the results: Tensile breaking load = 70 N, failure strain = 74% (in free fi bre), Tensile breaking load = 58 N, failure strain = 96% (at knot). Biochemical Engineering Journal 16 (2003), 97–105. The material may not be completely absorbed at this point, but it will have lost the majority of its initial tensile strength. It is a synthetic adsorbable suture material. Table 11.3 shows the mechanical properties of P4HB in comparison to current synthetic absorbable biomaterials (Martin and Williams, 2003). The mechanical qualities and biocompatibility of P4HB make it a more suitable absorbable suture than the currently available materials. Absorbable sutures are applied on the surgical wound temporarily to withstand normal stress on the wound. All surgeons performing blepharoplasty should have an excellent knowledge of orbital anatomy. Increased surface area does indeed produce the expected outcome of increasing degradation rate of the biomaterial. ScienceDirect ® is a registered trademark of Elsevier B.V.

Stock et al. Chromic Gut is the same as Plain Gut except that it is treated with chromium salts to delay the absorbtion time. Depending on the indication, we can supply sutures in many different sizes, which are absorbed in the short-, medium- and long-term. The eponychium and surrounding skin are closed with either nonabsorbable or absorbable material such as gut or rapidly absorbing Vicryl. Its high-quality material combined with precise braiding mechanism nearly eliminates the occurrence of post-operative suture fragments in the tissue. In addition, the molecular weight of the polymer can be controlled by controlling the enzymes in the engineered pathway, providing P4HB molecular weight up to approximately one million with polydispersity of 2–3 (Martin and Williams, 2003). Our Dermalon™ monofilament nylon sutures are inert, non-absorbable, sterile surgical sutures, 1 available dyed blue to improve visibility. Internal wound closure yields the best results when using an absorbable material. Catgut was the staple absorbable suture material through the 1930s, while physicians used silk and cotton where a non-absorbable material was needed. When Vicryl-Rapide was used to close skin around the orbit, the results were excellent.9 The most important finding was that there were no suture marks visible at 2 months after repair. At the high rate of test, the broken ends showed melting of individual fibres to form blobs of solidified molten polymer (Fig. However, she suffered continuing problems with the outer wound, which was oozing a pink sticky fluid. Copyright © 2021 Elsevier B.V. or its licensors or contributors. Patients can experience less discomfort during healing, less wound complications and a faster recovery. In addition, the half-life of this metabolite is only 35 min, and is rapidly eliminated by the body through the Kreb’s cycle as carbon dioxide (Sendelbeck and Girdis, 1985). Table 11.3. In contrast to the other absorbable sutures on the market, P4HB is produced through a fermentation process rather than through chemical syntheses (Martin and Williams, 2003). 2. Peter Rhys Lewis, Colin Gagg, in Forensic Polymer Engineering, 2010. Physick (1800's) - produced absorbable sutures from the skin of goats. The mechanical changes induced by absorption are not abrupt, but rather gradual in P4HB, unlike those found in other synthetic absorbable polymers such as PGA. Two monofilament absorbable suture materials, polyglyconate (Maxon) and polydioxanone (PDS), have some advantages over PGA and polyglactin-910. In contrast to the other absorbable sutures on the market, P4HB is produced through a fermentation process rather than through chemical syntheses (Martin and Williams, 2003). Alternatively, the stitch could simply have not been tied correctly in the first place using approved knots and placements in the soft tissues to be joined together. Catgut, reconstituted collagen, and cotton are available in twisted multifilament form, while Dexon®, Vicryl®, Monosyn®, Polysorb®, PolySyn FA®, Safil®, silk, polyester-based, polyamidebased suture materials are available in the braided multifilament configuration. Especially among older patients, preoperative ptosis should be identified, and it can be repaired during the blepharoplasty.39. Absorbable (e.g. Today we are going to discuss several of the many type of sutures as well as when they are indicated for use, suture material, and finally suture patterns that can be used. Absorbable suture materials are catgut (collagen derived from sheep intestinal submucosa), reconstituted collagen, polyglycolide (e.g., Dexon®, Dexon II®, Dexon S®), poly(glycolide/lactide) random copolymer (e.g., Vicryl®), antimicrobial-coated Vicryl® (Vicryl Plus®),poly-p-dioxanone (e.g., PDS®, PDSII® PDS Plus), poly(glycolide/trimethylene carbonate) block copolymer (e.g., Maxon®), poly(glycolide/ε-caprolactone) (e.g., Monocryl®, Monocryl Plus), and poly(gycolide/p-dioxanone/trimethylene carbonate) triblock copolymer (e.g., Biosyn®), poly(glycolide/ε-caprolactone/trimethylene carbonate) triblock copolymer (Monosyn®), poly(glycolide/L-lactide/ε-caprolactone/trimethylene carbonate) teriblock copolymer (Caprosyn®), and 100% poly-L-lactide (Orthodek®) (Chu et al, 1997).
