Controlling excess bleeding is one of those things that can overwhelm people. There are all kinds of acronyms and other memory joggers out there that try to help you remember what you’re supposed to do. I have a hard time remembering things like that under normal conditions, let alone a high stress situation! In this article I’m going to talk about how to stop bleeding and why it is the first thing you should do when treating trauma. I’m also going to explain why you do the things that you do. If you know why you do something, then you don’t have to memorize a checklist or an acronym that you most likely forget in the heat of the moment.
A long time ago I was told something by a Special Forces medic that has stuck with me to this day, “Put your hands on the red.” This simple phrase has gone through my head every time I’ve had to work on someone bleeding uncontrollably (mostly blast related traumatic amputations). It’s simple, easy to remember and easy to implement. It also does something else… it gets you doing something. Just starting to act can often get you past that initial shock and get you into the fight.
Why do you treat blood loss first?
The circulatory system functions like a hydraulic system. If there isn’t enough fluid in the system then the pressure drops. The pump has to work harder and harder to move fluid through the system as the pressure drops. Finally, the pump just can’t move the fluid through the system any longer. This is why you stop severe blood loss first, and as fast as you can. If your patient losses to much blood then it doesn’t matter if the person is breathing.
How do you stop bleeding?
You should take the time to put on a pair of surgical gloves if you have them available. This is for your own protection against any bloodborne diseases your patient may have. Yes, it will also stop some contamination of the wound and prevent infection, but this is secondary.
This article is mainly focused on stopping the loss of blood from severe wounds. If you are dealing with a smaller, manageable wound, the application of direct pressure is the best option. Apply a bandage to the area, put pressure on the wound with your hand or use a pressure dressing (like an Israeli bandage) and elevate the wound above the heart if possible. This reduces the blood flow to the area, and assists in stopping the bleeding. If the bleeding does not stop, then you will need to apply a tourniquet or a hemostatic impregnated dressing (discussed below).
When do you apply a tourniquet?
For amputations and wounds on appendages that are gushing blood, immediately apply a tourniquet.
Place the tourniquet 2-3 inches above the wound and tighten it until the flow of blood stops. Our goal here is to apply just as much pressure as is needed to stop the flow of blood. With amputations, I have found that the right amount of pressure is simply however much pressure it takes to stop the blood flow. When treating intact limbs, you should tighten the tourniquet until there is no pulse (taken at the wrist or the ankle).
For amputations, try to apply the tourniquet lower than the next joint up the appendage. For example, if someone has suffered an amputation mid-forearm, you would place the tourniquet below the elbow. This increases the likelihood that the elbow, and the stump below it, can be saved making the fitting of a prosthetic much easier. Do not try to save a joint in-lieu of efficient placement of the tourniquet!
Stay with the patient until they are handed off to a higher level medical authority. Make sure to tell medical personnel a tourniquet was used and the time that it was applied. You should mark the patient with a “T” and the time that you applied the tourniquet if you cannot stay with them (if you need to go to get help).
Never cover a tourniquet! The intent here is to ensure that it is obvious that a tourniquet was applied. You don’t want your patient to get to a hospital and wait for hours with a tourniquet on.
Take some time to practice this on yourself.
Apply a tourniquet to your own arm or leg and tighten it until you cannot feel a pulse. This will give you an idea of exactly how much pressure it will take to stop the bleeding on others. It will also teach you how to apply a tourniquet to yourself if you ever get injured while on your own.
Isn’t a tourniquet only used as a last resort?
Anyone who has served in the military since the Iraq War has probably already been taught this. I was surprised to see that there is still so much debate about the application of tourniquets in the civilian world. According to studies conducted in 2012, the early application of tourniquets to extremities during the wars in Iraq and Afghanistan saved between 1000 and 2000 lives. All with almost no record of long-term damage to these personnel.
Two hours is the generally accepted length of time that a tourniquet can be in place. Post-tourniquet syndrome is sometimes found in patients who have a tourniquet on for periods longer than 2 hours. This syndrome is marked by the loss of feeling in the limb. Patients normally regain full feeling in their limbs in 1-6 weeks.
Use of a tourniquet on patients is a proven way to save lives. When you are more than 2 hours from a higher level of care, you should try to stop bleeding by applying direct pressure first. If this doesn’t work, do not hesitate to apply a tourniquet.
Types of tourniquets.
There is a wide variety of commercially available tourniquets for sale. I prefer the Combat Application Tourniquet, but others like the SOF Tactical Tourniquet. Both will do the job and it really comes down to personal preference. Practice is key regardless of the type of tourniquet you decide to carry.
One company, RevMed, makes a ratcheting, daily wear belt called the Parabelt that can act as a proper tourniquet. It seems like a decent option for everyday carry, but may not be the best if you carry a pistol (and you should!).
You can always improvise a tourniquet if you have to. According to several EMS journals, a manual blood pressure cuff is one of the best improvised tourniquets. I have never tried it, but it came up several times in my research.
Other improvised tourniquets can be made from a t-shirt, belt, rope or other piece of material and a hard item that you can use as a windlass. Try to use a strip of material that is at least one inch wide. The more narrow that your tourniquet is, the more likely you are to cause damage to the tissue and nerves under the tourniquet. Begin by tying your improvised tourniquet around the limb, then place your windlass on top of the knot and make another knot on top of it. Use the windlass to tighten the tourniquet and then secure the windlass in place.
What is a hemostatic dressing and how do you use one to stop bleeding?
A hemostatic dressing is a bandage that is impregnated with a hemostatic agent. These agents accelerate the body’s natural clotting ability. They were originally designed for the battlefield, but are now in use across the civilian world by hunters, hikers, mountain bikers and the prepared. QuikClot Gauze and Celox Z-Fold Gauze are both common examples of these types of dressings.
Hemostatic dressings really excel when trying to stop bleeding from a wound in areas where it is hard to get direct pressure on an artery (like a wound high in the groin). They are also useful for deep penetrating wounds (such as a gunshot). Large, wide bandages are best for more open wounds. Long, thin bandages are best used on penetrating wounds.
Pack the dressing into the wound, trying to cover the entire bleeding surface. You can use another hemostatic dressing, or normal dressings, to fill the wound cavity for very wide wounds. Apply pressure to the wound by hand or by applying a pressure dressing. By packing the wound tight you are creating pressure that will help form a clot and stop the bleeding.
The two most common pressure points used are over the brachial artery (high in the armpit) and femoral artery (high in the groin). To assist in stopping the bleeding from a wound, put pressure on the brachial artery for an arm wound and the femoral artery for a leg wound.
If you are working with a partner, have one person place pressure on the pressure point while the other treats the wound. If you are by yourself, you can use your knee to put pressure on the femoral artery so you will be able to use both hands while treating the wound. A good way to put pressure on the brachial artery is to place something into the armpit area, then use your leg to push the patient’s arm toward their body, putting pressure on the artery. You can even do this to yourself if needed. Place a balled up towel or t-shirt in your armpit and place your bodyweight onto that arm.
If you are going to use the carotid artery to try to slow bleeding to a head wound, do NOT put pressure on both sides! You will cut off blood flow to the brain and cause the patient to lose consciousness.
You are going to be nervous! This is absolutely normal, especially if you are treating a loved one. Take a deep breath and try to calm yourself.
With some amputations it is hard to tell if you’ve stopped the bleeding. This is especially true if you’re on a surface that is quickly absorbing the blood. Before you move to another patient, be very sure that the blood flow has stopped.
Do something! Your actions can mean the difference between life and death.
I carry these three items: Adventure Medical Trauma Pak, Ever Ready Battle Dressing (AKA Israeli bandage), and Combat Application Tourniquet. For around $60 you can stop almost any type of bleeding. Together they make a kit that can fit in a large pocket or slide in a pack or purse. This isn’t the end all, be all of trauma kits but it is very robust for the size and cost.
As always, please contact your local Red Cross for proper first hand training. This article is as complete and current as we can make it, but it is not a substitute for first hand training.
