Suturing Deep Tissue Wounds with Non-Surgical Needles

Article by Lizzie Bennett of

To stitch, or not to stitch, that is the question. Stitching a cut does not seem like a particularly difficult thing to do, but suturing deep cuts, that should be closed in two or three distinct layers, without local anaesthetic and proper surgical needles (which are curved and make the job much easier), is not as straightforward as it might seem.

Firstly, suturing a wound that is still bleeding is likely to cause a haematoma, a blood clot that could quite easily put so much pressure on other vessels that blood flow ceases and tissue damage, gangrene occurs, this is especially true of the extremities. Some bleeding is good, the blood often brings with it debris that would otherwise contaminate the wound. What it will not get out is pathogens, germs from the object that caused the wound, or from the area directly surrounding the wound, people, animals, road surface, whatever.

Basic Suturing Technique in 7 Steps Using a Non-Surgical Needle

  1. Elevate the wound if possible, or use a tourniquet to stop the blood flow, a rubber glove stretched and tied around an arm to leg works well. When use of a tourniquet is impossible, use a pressure dressing. Whatever you use it should be wider than an inch to prevent it cutting into the skin.
  2. Bleeding stopped, though oozing is acceptable, you need to look at the wound to see the extent of it, roughly how deep it is. Clean the wound with antiseptic solution if you have it, saltwater if you do not. Wait five more minutes, whilst your sewing needle and thread are boiled to sterilize them, and then release the tourniquet, if used, as slowly as you can. Blood rushing back into a limb, especially a leg, can cause a sudden and profound drop in blood pressure, something to be avoided. Releasing it slowly also assists in not knocking off any small clots that have started to form at the end of the damaged vessels. If it bleeds profusely, reapply the tourniquet or pressure dressing and wait twenty minutes (ten for fingers and toes) rinse the wound again to prevent collected blood clotting and obscuring your view. You may have to do this several times.
  3. A deep wound is more than likely contaminated, if you have antibiotic capsules, open one up and mix with a little sterile water, just enough to turn it into solution, and put it in the wound. Wounds heal by granulation, from the bottom up. Suturing is not actually required to ensure a wound heals, what it does is speed up the process and helps keep the wound clean. A deep gash will take weeks, sometimes months to heal if it is not sutured. Suturing brings the two halves of the wound together so that when granulation occurs the new grown cells mesh together forming a strong join, just suturing the skin would be worse than leaving it to granulate, you are creating pockets, a perfect place for germs to grow and flourish.
  4. Okay, the sewing bit. Staying a little back from the wound edge put the needle in just off the vertical, like this go down to as near the bottom of the wound as you can and pull the thread through leaving a 2-inch tail. Insert the needle directly opposite where you removed it and back up through the skin on the opposite side of the wound, at an angle just off the vertical, like this / cut the thread leaving a 2″ tail and repeat this process along the length of the wound.
  5. Now they need tying off. Starting IN THE MIDDLE of the wound, gently pull both sides of one suture upwards and across each towards each other. Be gentle, tissue is delicate and tugging too hard will rip through the tissues. When the edges of the wound come together, or as near as together as you can get them to tie a knot, then two more. Now move to one end of the wound and do the same again. Now the other end of the wound and so on working towards the tied suture in the middle. The sutures should be placed about half an inch apart on long wounds, and about half that on short wounds. This spacing and working alternate ends prevents puckering of the skin which is very sore and can delay healing.
  6. Dab the area gently with a decent antiseptic solution. Do not use cotton wool, the fibers get into the wound. Cover with a sterile dressing and leave for 12 hours. Twice a day for the first five days dab with antiseptic and cover with a fresh dressing. It is normal for the needle holes to look very red and to be sore. If pus leaks from the wound check every few hours, if it does to subside, or become thinner, or clearer within 48 hours remove the sutures, clean the wound and re-suture. Adding antibiotics to the wound prior to suturing usually prevents this, and it is standard practice in hospitals for grossly contaminated wounds.
  7. The sutures need to stay in for between 14 and 21 days. To check if the wound is sound apply gentle opposing pressure with your thumb and fore finger between two of the sutures, If the wound does not hold together leave the sutures in and do the same test daily. To remove them, wet them with sterile salt water, cut the knots and tease them out. Do not cut all of the knots at the same time, check that the wound holds together by removing the center one first and checking as previously stated. If it is not quite there, leave the rest in and check daily. If the wound is sound, remove the rest of the sutures.

This wound will not have the best scar in the world but it will be much more pleasing than a granulation scar, also, granulated tissue is often quite sensitive to knocks, bumps and sometimes even fabrics. Suture scars tend to be far less sensitive and are less prone to abrasive damage than is granulation tissue.

How close does each pass of thread have to be to the previous?


The sutures should be placed with gaps between them but it is difficult to be precise as skin, the way it holds together is a very individual thing. There should be no gaping between the sutures as it will prevent the skin healing properly.

Sorry I can’t answer this with precision


Question / response:

This advice is insane.  Deep wounds in a non-hospital environment should ALWAYS be packed open and left to heal by primary intention, if not, gangrene and death by septicemia is the likely outcome.
I have been an E.R. (casualty) physician for 26 year, five of them in a trauma center, and again, I say this advice is insane and likely to prove deadly.  LEAVE ALL DEEP AND CONTAMINATED WOUNDS OPEN


Thank you for you comment. I totally agree where there is any sign of  gross infection a wound should not be sutured, I also agree that in ideal conditions such a wound may well not be sutured. This article however was written for non-ideal conditions. I will also state that is is common practice for deep tissue wounds to be sutured both in the hospital environment and on the battlefield. I also have worked in accident and emergency and I agree wounds are often packed, the patient is then transferred to theatre where quite routinely such wounds are sutured.

It is stated quite clearly that this is a dire solution for dire circumstances, and if any medical help can be found that is the course that should be taken, allowing a qualified medical doctor to take over the wound care and make the decisions most appropriate for that patient.

I also agree that closing these wounds can lead to complications, as can leaving them open. Packing and the subsequent debridement of wounds is something that ideally should be done in a sterile environment, which would not be available in a shtf situation.

In a situation where medical help is not available, people will try to fix the problem on their own, they will have no choice. I think it is preferential that if they are going to do it anyway, they should be given a little advice on how to wash out a wound and use antibiotics in ways that can maximise their potential.

Take care
