Self-absorbable seams: types, healing time

In some cases, for example, during surgical intervention, as well as after childbirth, the application of absorbable sutures is required. For this special material is used. There are many varieties of absorbable threads. The term healing of such wounds depends on many factors. So, how many dissolving sutures dissolve?

Main types of joints

To answer this question, it is necessary to clarify which main types of seams exist. Typically, this is:

1. Internal. Such seams are superimposed on injuries resulting from mechanical stress. To connect the tissues at the point of rupture, certain types of tissues are used. These self-resorbable seams heal fairly quickly. Often, they are imposed on women after giving birth to the cervix. In this case, anesthesia is not required, since this part of the genital organ is devoid of sensitivity.
2. Outdoor. They can also be applied using absorbable material. After childbirth, such seams are made during a rupture or when the perineum is dissected, and also after operations. If a normal material is used, then it must be removed on the 5th-7th day after surgery.

It should be noted that the self-absorbing seams can heal after a few weeks. It all depends on the type of material and its composition.

What are absorbable stitches

Self-absorbable seams are applied almost always. It is extremely rare for the healing of wounds used surgical material, which is resistant to hydrolysis. Stressing is considered to be sutures, which lose their strength as early as 60 days. There is a dissolution of the filaments as a result of the action:

1. Enzymes that are present in the tissues of the human body. In other words, these are proteins that control and accelerate the course of chemical reactions.
2. Water. This chemical reaction is called hydrolysis. In this case, the filaments are destroyed under the influence of water, which is present in the human body.

Synthetic woven polyglycolide yarn «MedPGA»

Analogues of such surgical material are "Safil", "Polysorb", "Vikril".

Self-absorbable sutures after surgery or after childbirth can be superimposed using the MedPHA thread. This surgical material is made on the basis of polyhydroxyacetyl acid. Such fibers are coated with a resorbable polymer. This is required to reduce the fusility and capillarity, as well as to reduce the sawing effect that occurs when carrying material through the fabric.

Through how much the "MedPGA" thread dissolves

The self-absorbing seams applied with the help of "MedPGA" thread are subjected to hydrolytic decomposition, which is strictly controlled. It should be noted that such material is sufficiently strong. After 18 days, the filaments retain up to 50% strength properties.

Complete resorption of the surgical material occurs only after 60-90 days. At the same time, the reaction of the body tissues to the "MedPGA" threads is negligible.

It is worth noting that such surgical material is widely used for suturing all tissues, except for those that are under tension, and also do not heal for a long time. Most of the "MedPGA" threads are used in thoracic and abdominal surgery, gynecology, urology, plastic surgery and orthopedics. However, it is not used on the nervous and cardiovascular tissues.

Synthetic woven polyglycolide yarn "MedPGA-R"

Analogues of similar surgical material are "Safil Kvik", "Vikril Rapid".

"MedPGA-R" is a synthetic thread made on the basis of polygliglactin-910. Such a surgical material is covered with a special absorbable polymer. This reduces friction when passing the thread through the tissues of the body, and also reduces the fusility and capillarity. Thanks to this surgical material, you can impose self-absorbing seams.

Through how many the "MedPGA-R" fibers are resorbed

"MedPGA-R" is a material that lends itself to hydrolytic decomposition. Such threads are strong enough. After five days, 50% of their strength properties are retained. Complete resorption occurs only for 40-50 days. It is worth noting that the tissue reaction to the surgical material "MedPGA-R" is insignificant. In addition, the threads do not cause allergies.

This material is used to apply sutures to mucous membranes, skin, soft tissues, as well as in those situations where short-term wound support is needed. However, there are exceptions. Such yarns are not used for nerve and cardiovascular tissues.

Synthetic woven polyglycolide yarn «MedPGA-910»

Analogues of such surgical material are "Safil", "Polysorb", "Vikril".

"MedPGA-910" is a resorbable yarn, made on the basis of polygliglactin-910. The surgical material is also treated with a special coating that reduces the "sawing" effect when the material passes through the tissues, and also reduces the capillarity and fibrillation.

Terms of resorption «MedPGA-910»

So, when are dissipated self-absorbing seams applied with the use of surgical material "MedPGA-910"? Such threads have a high strength index. However, they are also subjected to hydrolytic decomposition. After 18 days, the surgical material can retain up to 75% strength properties, after 21 days - up to 50%, after 30 days - up to 25%, and after 70 days there is complete resorption of the threads.

This product is used when suturing soft tissues that are not under tension, as well as those that heal quickly, in plastic, thoracic and abdominal surgery, gynecology, urology and orthopedics. You can not use "MedPGA-910" when applying seams to nerve and cardiovascular tissues.

Monononize the "PDO"

Analogues of similar surgical material are not so much. This is "Biosyn", as well as PDS II. Such yarns are characterized by a high rate of biological inertness, nonfiltillary and non-capillary, hydrophobic, do not injure tissues when passing through them, are elastic, sufficiently strong, knit well and hold the knot.

Through how much the monofilaments dissolve

Mononites "PDO" are hydrolysable. As a result of this process, dihydroxyethoxyacetic acid is formed, which is completely eliminated from the body. Two weeks after suturing, the surgical material retains up to 75% strength. Complete dissolution of the filaments occurs within 180-210 days.

Regarding the field of application, the surgical material "PDO" is used for the application of seams and the connection of soft tissues of any type, including for stitching the cardiovascular tissues of the child's body, which are subject to further growth. However, there are exceptions. Do not fit monofilament for stitching tissues, where support for wounds up to 6 weeks, as well as those that are exposed to high loads, is required. You can not use suture material when installing implants, artificial heart valves, as well as synthetic vascular prostheses.

So how much will the sutures dissolve?

Next, we will consider everything concerning what are the self-absorbing seams after delivery: when they resolve, do they require care. Do not forget that the timing of wound healing and the complete disappearance of the threads is affected by many factors. First of all, you need to know what raw material the surgical material is made from. In most cases, the filaments begin to dissolve after 7-14 days after suturing. To speed up the process, after healing the wound, the health worker can remove the nodules. To determine the timing of resorption of the strands, please check with your doctor:

1. What seams were imposed.
2. From what material threads were made.
3. Approximate terms of dissolution of suture material.

In conclusion

Samorassasyvayuschivayuschivayuschivayuschie yarns are often used for suturing surgical wounds, which are located in the deep layers of tissues, as well as on the surface of the skin. For example, when transplanting organs.

The same surgical material is also used for sewing wounds and ruptures obtained during childbirth. A lot of research has been done. Their results showed that the suture material made of polyglycolic acid completely disappears only after four months, and the material based on polyglactin - after three. In this case, the self-absorbing seams will hold the edge of the wound until it is completely healed, and then gradually begin to break down. If the threads remain for a long time and cause discomfort, then you should seek the help of a surgeon or a doctor in charge.
