Healing

Tissue healing (of a surgical or traumatic wound) is a natural phenomenon involving processes of repair and regeneration.
The quality of the healing and the length of time involved depend on numerous factors, both local and general (aetiology, site, type of tissue, patient‘s general state of health, infection, etc.).
The role of a suture is to assist healing by supporting the tissues throughout the critical stage.
That is why it is important to know how long the different body tissues take to heal. This crucial information should be contrasted with the suture absorption time so that, by matching the two, the appropriate suture can be chosen, ensuring optimal conditions for successful healing.

TissueHealing Time
Skin1 to 2 weeks
Subcutaneous tissue2 weeks
Peritoneum4 to 10 days
Abdominal fascia5 to 6 weeks – regains 75% of initial strength in 9 months
Digestive tract2 to 3 weeks
Uterus8 days
Vagina / perineum8 to 10 days
Bladder5 days – regains 75 to 90% of initial strength in 2 weeks
Ureter7 days
Joint capsule5 to 6 weeks
Ligaments / tendons6 weeks – regains 50 to 70% of initial strength after 1 year

B. Braun sutures offer a variety of resorption profiles, providing made-to-measure, indication-specific.
In addition, we know that after incision and suturing the length of time necessary for tissues to regain their initial tensile strength varies a great deal depending on the type of tissue involved.
The tensile strength of healing tissue is always weaker than the initial strength of the injured tissue.
This parameter too is a determining factor when it comes to choosing a suture material.
For example, fascia takes several months to heal. In fact, this poorly vascularised tissue, which is subject to variations in pressure, heals slowly, yet secure closure of the abdominal cavity [7] depends precisely on the fascia, although the latter will only regain 70% of its initial strength after laparotomy. [9]
This particular situation requests a customised suture material.
B. Braun offers surgeons an innovative thread for abdominal wall closure: Monomax®. This thread has unique properties that meet the specific requirements of laparotomy surgery.

Hydrolysis

Hydrolysis is the mechanism of resorption see Resorption >> of absorbable synthetic sutures, and leads to the gradual disappearance of the thread. This breakdown is more regular and more predictable than enzymatic reactions (as in the case of catgut), which partly explains the increase in use of absorbable synthetic sutures.
