During the operation, the superimposed outer and inner seams. When applying internal sutures your doctor uses absorbable material is catgut, which is increasingly "dissolved" in 1-2 months. When stitching internal tissues surgeon puts a single ligature or a continuous suture on the operated area, be sure the doctor bandaging by a catgut of large vessels.
When connecting the dissected tissues of the skin, the surgeon often uses simple nodal seam, which is applied on wounds of any complexity. Looks like the outer seam as a separate transverse of the ligature with the nodes that overlap across the section line. After 5-7 days the suture material is removed. The scar after healing of the external nodal seam, as a rule, looks like a one lane width of 1-3 mm with cross lines about the size of 1-2 cm, which are repeated every 2-3 see
Sometimes the surgeon uses the technique of continuous suturing of the dissected layers of the dermis. These types of stitches help to pull the skin during surgery with removal of the portion of the dermis or in the operated area. When applying continuous suture tissue pulled together tightly throughout the dissection. In this technique the needle should go strictly in front of her place of puncture.
Cosmetic the incision is imposed most often in small smooth surgical incision up to 10 cm long word for this kind of cosmetic stitching because after healing it looks like a thin strip, the width of the scar up to 1 mm, has tuberosity. This kind of seam is applied only to clean the wound, surgery nevospalitelnogo body (caesarean section), if you change the size of the breast, remove naevus, etc.
In the process of wound healing and scar formation 4 stage isolated, each seam has a certain look. The first stage begins immediately after surgery and lasts about a week. In this period start of active substances that provoke the inflammation, so the seam is erythematous and edematous. In the second stage formed the "young" scar, there comes this period when the sutures are removed and lasts up to a month. The scar at this stage it looks bright pink, susceptible to injury and inflammation, so you need a protective mode to avoid stretching the fabric, not swim in water etc. the Third stage - the formation of a Mature scar, lasts from 1 to 3 months. This period is characterized by the formation of large amounts of collagen and growth of connective tissue, the scar is pale pink. The fourth stage lasts to years and is characterized by the formation of a white scar of dense connective tissue.
With a weak immune system and infection of the suture line duration of healing may increase. In this case there is a convoluted bumpy scar with a width of several mm.
Advice 2 : What types of surgical sutures are
Doctors joke that the surgeons are the same pathologists, only their "clients" still somehow alive. Black humor does not interfere with the surgeons every day to save hundreds of lives by removing and stitching, cutting and reshaping". The skill of the physician depends not only on the patient's health but also its appearance, because of the interventions scars.
Types of stitches in time
The surgical incisions are performed in two ways: manual and mechanical.
For stitches using suture material that can be biological, absorbable sutures – catgut or synthetic non-absorbable - nylon, nylon.
The seams, which is applied immediately after the operation, is called the primary. If the wound after surgery granuliruth on suturing, which is called secondary.
There are still provisory stitches, it is applied on the wound, but the threads do not tighten. This is done in case there is a risk of development of inflammatory process in the wound. These sutures are tightened after three to four days for testimony.
Seam to impose on the third day after surgical treatment wounds referred to as delayed primary suture.
Types of stitches according to the type of execution
If the wound is shallow and is located on the surface of the skin, it imposes a removable suture of non-absorbable material, after wound healing, the suture is removed. Wounds that deeply hurt the soft tissue sutured with absorbable suture material. The threads of this seam not removed.
According to the method of suturing wounds of the joints are divided
- on the host,
- a continuous,
A suture by hand use needle holders, which may be straight or curved. In needle holders needle is inserted. The needles may be of various configurations. At the top of the needle is the eye, through which odevaetsya thread of suture material.
Currently, more and more applications received mechanical sewing machine in which thread is using tantalum brackets. If the wound is only superficial and is not affected by soft tissue, a suture on the wound and the nurse who conducts self-administration. With deep, touching the soft tissue of the wound that requires debridement, suture imposes only a practitioner.
Removal of stitches depends on the condition of the wound, the General condition of the patient and on the condition that the skin around the wound tight. Special attention should be paid to wound healing in the elderly.
For sutures in some organs and tissues of the human body used a specific surgical sutures: intestinal, nervous, vascular and tendon joints.
In all cases, and types of surgical sutures all surgical instruments, suture and dressing materials must be strictly sterile.
