Does the choice of suture material affect the incidence of wound infection? A comparison of dexon (polyglycolic acid) sutures with other commonly used sutures in an accident and emergency department.

One hundred and four patients with superficial lacerations were sutured with either Dexon (polyglycolic acid), silk, polyethylene or nylon sutures. The incidence of postoperative tissue reaction and wound infection was compared. There were few complications and these occurred with almost the same frequency in each suture group, although there were slightly more cases of infection in the patients who were sutured with silk. Dexon was seen to possess certain advantages in that it caused as little tissue reaction as the other sutures but did not have to be removed subsequently. This could clearly be of benefit to the patients and hospital staff alike.

[Experimental comparative study of microsurgical nerve sutures. II. Water-proof sutures and suture by simple approximation of the stumps].

After having demonstrated in a previous paper the advantages of an early surgical repair of injured nerves over a delayed suture, the author, following the same methods--electrophysiological and histological controls--comes to the conclusion that the so-called water-proof suture technique compared with a simple bringing up together of both stumps of the nerve, gives by far higher degrees of regeneration.

[Comparative experimental study of microsurgical nerve suture. I. Immediate suture and delayed suture].

Impressed by multiplicity of theories and conceptions concerning nerve surgery and by the difficulty to draw grouded conclusions from the different and contradictory work available from the litterature on the subject, the author makes a revision of the biology of the nerve, to be used as a point of departure for investigation. Based on the fact that protheosynthesis capacity of the nerve cell is known to be at its top value during the first week after the lesion of the nerve, the author endeavours to compare immediate suture with delayed suture. This comparative study is based both on electrophysiological and histological data and show clearly enough the real advantage of trying nerve reconstruction as early as possible, to avoid progression of devitalisation and invasion by fibrosis of both stumps. The surgical procedures are made with the help of the operating microscope and the same technique is used in both groups.

[Quantifying suture tension of corneal sutures with the suture forceps with strain gauge strips].

To achieve uniform tensions on corneal stiches a modified tying forceps was developed. This forceps provides the possibility to measure the tension which is put to a nylon thread (10-0) by means of surface mounted strain gauges detecting the forceps jaws' bending. The results are registered and displayed electronically. To obtain a preselected tension, a limit value switch and a tare unit is used. A first series of registrations showed reproduceable values and confirmed a linear correlation between forceps jaw bending and traction force. A prototype and possibilities of technical improvement are demonstrated.

Suture technic and suture-holding capacity. A model study and a theoretical analysis.

The suture-holding capacity (SHC) of six representative surgical suture materials was analyzed. The single loop, the far-and-near, and the near-and-near suture technics were used in the study. The SHC was found to depend on: (1) the coefficient of friction between the suture strand and the tissue; (2) the distensibility of tied and untied fiber; (3) the holding capacity of the knot used; and (4) the strength of the untied strand. Knot-holding capacity (KHC) was of the greatest importance when the single loop technic was used and when the friction between the suture strand and the tissue was low. When the near-and-near or the far-and-near technic was used, the SHC was influenced little by the strength of the knot, especially when the coefficient of friction between strand and tissue was high. The near-and-near suture technic produced the strongest sutures for all materials except Dexon, for which the far-and-near technic produced the strongest sutures. With a correct suture and tying technic, one can optimally use the strength of the suture material and one can use thin strands.

[Prolene and vicryl as synthetic sutures for intradermal suture technics].

It could be shown that beside the non-absorbable synthetic suture material (Polypropylene) for the subcuticular continuous skin suture absorbable synthetic suture material (Polyglactin 910) is suitable for the buried subcuticular skin suture to obtain good esthetic scars in plastic surgery. Experiences with Polyglactin 910 in over 300 patients are presented. In no case wound healing was disturbed as a result of the suture material. Further application will give more information about the usefulness of the absorbable synthetic suture material Polyglactin 910 for the buried subcuticular skin suture.

Strength of knots in surgery in relation to type of knot, type of suture material and dimension of suture thread.

The 12 commonest types of suture material in dimensions 7/0, 5/0, 000, 0 and 2 (USP, 1965) were tested in 16 types of knot with regard to tensile strength of knot using the loop method. The results are given in tabular form as the strength of the loop for alltypes of knot tested, and as the mean knoe efficiency for certain groups of knots. The knot efficiencies are compared with regard to the different types of knot, the various types of suture material, and the different dimensions of thread using statistical methods including variance analysis. The strength of unknotted thread within a given dimension showed considerable variations for different suture materials: a given material could be more than twice as strong as the weakest material of the same dimension. With very few exceptions, the knot was the weakest point in a suture loop subjected to disrupting forces. The knot efficiency depended very largely on the type of knot and the strength of different types of knots varied from 3% to 99% of the corresponding unknotted thread. With the exception of two types of steel thread and both types of catgut, the efficiency was low for most simple crossed knots and for many simple parallel knots, and here considerable variations were recorded. Knot efficiency was clearly highest and showed least fluctuation with complex and particularly complex knots, and was closely similar for these. The dependency of knot efficiency on the type of suture material (mean for 16 knots) varied from 44% (polyethylene) to 90% (multifil steel). The variations in dependency on material were greatest with simple knots and with certain materials, and decreased with increasing knot complexity. The dependency of knot efficiency on the dimension of any particular suture material was apparently of much less importance than the type of knot and type of material.

Absorbable iris suture. An experimental evaluation of polyglycolic acid suture.

Suturing of traumatic or surgical iris wounds has proved to be a safe and feasible microsurgical procedure. Various suture materials have been tried experimentally and clinically. If the human iris forms scar tissue the ideal suture would be an absorbable, inert, proteinfree material causing no uveal reaction. It was the purpose of this study to evaluate the ocular tissue reaction to nylon, virgin-silk and polyglycolic acid (Dexon) after suturing of an experimental iridomy in 24 rabbit eyes. The tissue response was studied by biomicroscopy, iris fluorescein colour angiography, and histology. Nylon did not disintegrate and caused virtually no inflammatory reaction. Silk showed fragmentation and complete absorption after four to six months with moderate tissue response. Polyglycolic acid gave rise to a marked uveal reaction and depolymerised from the fifth to the sixth week. There was no wound dehiscence of the iris scar and the pupillary function remained intact. It is concluded that the non-absorbable materials are superior to the currently available absorbable sutures in iris surgery.

[In vivo investigations on suture reactions under sterile and not sterile conditions. Comparison of absorbable and nonabsorbable suture materials (author's transl)].

Suture materials from plant and animal substances are increasingly being replaced by synthetics. Among the nonabsorbable materials, synthetics are much superior regarding infection, threading and knot strength. A coating can improve management, which is currently more favourable with silk and cotton. Absorbable polyglycolic-acid sutures enable controlled reduction of thread breaking, but catgut sutures do not. Absorption is significantly accelerated by infections, while pH-fluctuation is less important. For infected tissue, monofile or pseudomonofile sutures are most suitable.

Sutures and suturing--current concepts.

Currently available suture materials can be classified as nonabsorbable and absorbable types. Too often the surgeon selects the material on the basis of handling properties alone. The "perfect" suture material does not exist. Physical properties such as tensile strength, reactivity, size, and absorbability must be considered in light of current knowledge of wound healing. Placement of sutures is obviously as important as selection of material.

[The position of gastrointestinal suture technique. Advances through mechanical suture methods (author's transl)].

At the present time various materials and methods of manually suturing the gastrointestinal tract are used in parallel. While these methods satisfy basic standards, there is scarcely any detectable difference in the results. Further development in manual suturing with reference to security from failure and reduction of the expenditure of time is unforeseeable. Adhesive methods cannot achieve any importance in the gastrointestinal tract. Presently only the fully mechanical suture methods described at the end of the sixties show promise of possible future development in the gastrointestinal tract. They are suitable for as much as 80% of plastic gastrointestinal operations, but still need statistical comparison of results.

Absorbable subcuticular sutures. How to avoid the childhood ordeal of suture removal.

Suture removal is psychologically traumatic to a child, and in the majority of relatively minor elective operations is a totally unnecessary procedure. Skin repair with subcuticular sutures of absorbable polyglycolic acid (Dexon) is advocated. Techniques of suturing are described. Advantages, potential disadvantages and contraindications are discussed.

Polyglycolic acid suture in peripheral nerve II: sutured sciatic nerve.

This experiment investigates the holding property of polyglycolic acid suture in repair of divided dog sciatic nerves and the influence of absorption of this synthetic material on regeneration. The conclusion is that PGA maintains its tensile strength sufficently long to allow both physical union and good regeneration of the divided nerve. The suture absorption does not influence regeneration.

[New suture material for intestinal sutures in children].

In the experiments on puppies the authors studied the possibility for the use of ophthalmologic tendinous threads as a suture material for interintestinal anastomoses after intestinal resection. Ophthalmologic tendinous thread was used in a neonate with atresia of the small bowel. Six months' follow-up revealed a good result.

[Blood vessel sutures with absorbable suture material: roentgenological, hemodynamic, light and electron microscopy findings. I].

Simple end-to-end anastomoses were performed in the common carotid and femoral arteries and in the jugular and femoral veins of dogs. In other dogs, lateral sutures (running) consisting of absorbable material made from polyglycolic acid were inserted. No occlusions, aneurysms, or infections occurred in the arteries. Without heparin, the patency rate after up to 234 days was 98%. In veins, the observation period was 60 days and a patency rate of 83% was found. All vessels were studied by angiography and by light and electron microscopy. Additionally, an original method of hemodynamic assessment was used (Turbulence Index). The alternating effect of morphological variations in the vessel wall and the degree of blood flow disturbance was evident.

Experimental suture studies in strabismus surgery. II. Comparison of tensile strength of plain catgut with polyglycolic acid (Dexon) sutures after extraocular muscle surgery.

From our experimental studies it appears Dexon satisfies more of the criteria for an ideal suture for strabismus surgery than plain catgut for the following reasons. Its handling, tying, and knot-holding (if tighthened firmly) qualities are excellent. Tissue reaction is minimal. It seems to be non-antigenic. Of paramount importance. Dexon's tensile strength is high initially and it retains its strength through the critical period of muscle-scleral wound healing, then dissolves in a rapid uniform manner.
