A Short Discourse on Opening up of Wound Post Suturing (Wound Dehiscence)

Wound Dehiscence

Post surgeries, the surgeons and doctors stich the internal tissues or the skin of the patients. This enables the wound to heal up in the right way. This is the process that is better known as suturing. While suturing is imperative for the process of healing, if done in the wrong way, this can give rise to a huge number of complications.

So let’s take a look at what wound dehiscence is, why it occurs and the potential causes of this condition.

What is Wound Dehiscence and Why It Occurs

Wound dehiscence means opening up of the wound edges following the closure of wound by suturing.

There can be a number of factors that can result in wound dehiscence. This can include surgical error, age, cancer, diabetes, fluid-coagulant balance, infection, unsuitable suture type, obesity, improper usage of stitch, smoking, radiation presence at the site of incision, inadequate nutrition of the patient, previous scarring, amplified pressure applied to the edges of the wound (generated by laughing, lifting or straining, sneezing, coughing, , vomiting) and corticosteroids chronic usage.

Poorly taking care of the wound throughout the surgery can also cause dehiscence. The location of the wound is another cause of the dehiscence. There are more chances of the rupture if the wound is located on areas prone to high tension or on mobile areas like the back, shoulder or legs. Apart from that, those patients with Ehlers-Danlos syndrome are also quite prone to dehiscence.

Potential Causes of Wound Dehiscence

  • The knot is too loosely tied.

  • A knot that is not appropriate is used- for example, a square knot instead of a granny knot was used.

  • Instead of a needle featuring a round body, a cutting one was used. Some structures of the body are quite friable and thin. So keep it in mind that a cutting one, like a scalpel, is capable of cutting through the tissue. In certain situations, you may think of using a reverse cutting needle.

  • A suture that is not appropriate is chosen like when in a tension area a thin mono-filament suture is put to usage.

  • You need to deal with the issue of infection first. This can also occur when sutures are positioned in a wound that was infected.

  • If there is excessive tension on the wound. The closure of wound should be tension-free.

  • The wrong technique of suturing is chosen. For example, placing a suture that is continuous in place of mattress or interrupted sutures.

  • If the suture is placed too close to the edge of the wound.

  • A foreign body is mistakenly left in the wounded area.

  • The sutures are done away with too soon. This should not be done in the lower extremities.

  • A bleeding from the artery is placing a great pressure within the wound and this in turn, forces it to open. By appropriate means, always control the bleeders like the diathermy and ligation.

  • A blood clot is created and is forcing to open the edges of the wound.

  • The sutures have been placed on a malignant tumour.

The above can occur even when you are using the best quality tools and sutures like Stratafix suture. So take utmost care to avoid the incidents mentioned above so that your patient can heal fast and recover from the wound as soon as possible.
