Weapons Placement: Part II

Knowing when and where to implement various techniques is one of many important aspects of tactical medicine. In a previous entry, we discussed weapons placement during treatment. We proposed positioning your primary weapon behind your knees when the tactical situation allows. The video below is a prime example of when this technique should not be used. The medic is supposed to be in the Care Under Fire (CUF) phase. In this phase of tactical medicine, while treating in the prone position, your weapon should be immediately accessible and ready to engage threats. Due to positioning, you do not have rapid access to your secondary weapon. Slinging your weapon is not a sound choice, because its position will hinder putting it into operation. Your best choice in this situation may be to un-sling your weapon and route your arm through the sling. Don’t, however, put the sling all the way on. Next, set the weapon on your casualty, making an effort not to burn them with a hot barrel. Routing your arm through the sling maintains a point of attachment and acts as a friendly reminder; however, it doesn’t interfere with your ability to provide treatment. When you move, your weapon will still move with you and is readily accessible for periodic engagements.

Most courses teach not to use your casualty as a work table or place supplies and equipment on them. This is a good habit to get into, but this is a definite exception. Your weapon is now a lifeline for you and your casualty, and it needs to be readily accessible.

TacMed Key Points:

    1) Situation dictates weapons placement
    2)CUF phase requires your weapon to be accessible no matter your position
    3)In order to increase your and your casualty’s chance of survival, you may have to “break a rule” and use him as a table or a firing platform.

Care Under Fire:Providing Treatment Behind Cover

Providing care under fire is a mentally daunting task. Few other phases have so little to do with medicine and so much to do with your surroundings. Even with a sizable piece of cover, it is easy to make mistakes and expose yourself during treatment when focused on patient care.

In the video you can see the medic doing a decent job of maintaining a low profile during treatment, then, while shifting from the casualty’s leg to his head, he elevates his body during movement. This action briefly exposes his head to enemy fire. An analogy we like to use to explain the atmosphere you are operating in when providing true “care under fire” is that it can be equated to working in confined space. The difference is that instead of bumping your head or elbow on a concrete slab, the concrete slab is replaced by incoming fire. It is generally best for everyone if the medic avoids bumping parts of his body into bullets.

The effort to maintain your position of cover is exponentially more difficult in urban areas or areas with varying points of elevation. You should regularly reassess the effectiveness of you position as the fight progresses. If the enemy force has moved to an elevated position, or possibly to the second or third story of a surrounding structure, you just lost about 50% of your position. Now you must either be more cautious when moving to provide treatment or you need to shift to maximize the use of the position you are in. If in a structure with external windows and “plunging fire” from surrounding buildings, the safest position is on an external wall, in the corners, away from windows. However, remember to consider the type of materials used to construct the building before selecting this position. This position is not recommended if in a vinyl-sided home or a 3rd world type structure.

Failure to practice working in tight quarters behind cover can lead to potentially fatal mistakes in combat. Incorporate these situations into your training and use them to increase the effectiveness of your equipment (e.g., how and where you store or pack it) and how to asses your positions.

Here are some tips for operating in this phase of tactical medicine:
-Keep items required for Care Under Fire or buddy-aid easily accessible.
-Reposition casualties to minimize their level of exposure and yours.
-Don’t lose touch with your surroundings, regularly reassess the enemy’s position.
-Don’t be afraid to move to a new position if the tactical situation allows.
-If in a structure, be mindful of interior and exterior threats.
-Keep your treatments as simple as possible then get back on your gun!

Cross-loading Medical Supplies

A medic’s bag is never big enough, but it’s always too big. There is no way for you to carry enough medical equipment in your bag to treat every possible injury. If you over pack your bag, it makes it difficult to work out of, it slows you down and it limits your ability to maneuver through the battlespace. If you under pack, you might not have the items you need to treat a serious casualty.

One way to maximize the medical supplies on the objective while minimizing the burden on the medic is to cross-load supplies. Medics carry ammunition for their weapon; operators should carry supplies for their wounds. This has been practiced for quite some time in the military, but it is just making its way into the civilian/ Law Enforcement sector. Soldiers are issued individual first-aid kits containing the essential items for initial care on the battlefield. The majority of what is needed for self-aid and/or buddy-aid is contained in these kits, and they are a great example of cross-loading on a massive scale.

When considering items for cross-loading, look at items individuals are actually trained to use and that take-up a lot of space in your bag. Bandages and tourniquets are good examples of items that are high-volume items in both use and consumption of space. Spreading these items throughout your element will be a major help in a few ways. For example:

1. It reduces the medic’s load
2. It spreads medical assets across the team reducing treatment times.
3. Increases the amount of medical supplies on the objective

Items recommended for cross-loading:

1. Bandages
2. Tourniquets
3. Chest-seals
4. Snivel meds (OTC Drugs)
5. IV fluids

Specialty items that are medic-specific tools should not be cross-loaded. These are items you want to protect and have at your immediate disposal if required. Some of those items include:

1. Advanced airway management
2. Special diagnostics
3. Pain-control meds (this is unit dependent)
4. Surgical instruments

What you decide to cross-load should be based on mission requirements, level of your teams’ medical training, medical director’s guidance, and local protocols. Every organization will have different requirements based on the above factors. It’s up to you to develop your plan.

Tourniquet Use in Pre-hospital Civilian Trauma Care

Tourniquets are an effective means of arresting life-threatening
external haemorrhage from limb injury. Their use has not
previously been accepted practice for pre-hospital civilian
trauma care because of significant concerns regarding the
potential complications. However, in a few rare situations
tourniquet application will be necessary and life-saving. This
review explores the potential problems and mistrust of
tourniquet use; explains the reasons why civilian pre-hospital
tourniquet use may be necessary; defines the clear indications
for tourniquet use in external haemorrhage control; and
provides practical information on tourniquet application and
removal. Practitioners need to familiarise themselves with
commercial pre-hospital tourniquets and be prepared to use
one without irrational fear of complications in the appropriate

Use of Hemostatic Agents

It is important to understand that science has not yet isolated the compounds essential in the production of fairy dust. Modern hemostatic agents require proper technique and training to function properly. Simply placing these products onto or into wounds does not solve all of your problems. If members of your organization are issued hemostatic agents, it is essential that they are trained on the agents and fully understand their limitations.

There are four steps you ought to follow when using hemostatic agents:

    1) Prep your equipment. Set yourself up for success by having all required components ready before addressing a bleed (i.e., agent, gauze, and bandage).

    2) Identify the bleed. Placing or pouring an agent onto or into a wound without identifying the bleed is unwise. If you have a large cavity that requires hemostatic agent, you must make sure the agent is placed DIRECTLY ONTO THE damaged vessels in order for it to work. Otherwise, you are wasting blood cells and agent.

    3) Proper placement. After identifying the bleed, you must ensure the agent is placed DIRECTLY ONTO THE BLEEDER. If you do not, you run the risk of creating a “crust” made of blood and agent above the vessels. In so doing, you have visibly stopped the bleeding by forming a large clot, but it has not stopped the bleed.

    4) Pressure. Hemostatic agents do not relive you of the basics that are required for hemorrhage control. After using a hemostatic agent, you MUST place gauze behind it in order to create pressure, so as to allow a clot to form. Otherwise, you run the risk of the agent being washed away or of a “crust” forming and creating a hematoma. It is also necessary to use the gauze to hold the agent in place and prevent it from shifting during patient movement. A minor shift during movement can cause a re-bleed which could be fatal if overlooked during re-assessments


    1) Can the basics stop the bleed?
    2) Is the casualty hypothermic? If so, clotting is a factor.
    3) External environmental factors. For example, wind (or rotorwash) may blow a powder agent into the casualty’s or your eyes.
    4) Location of injury (e.g., face, neck, abdomen).
    5) Staying basic with the basics
    6) Training is a must. If end-users (i.e., medics, operators, officers) do not know the basics of hemorrhage control, then using hemostatic agents is not wise.

Wound Packing: Techniques and Considerations

The ability to pack a wound is an essential skill for the tactical medic. While a tourniquet is an excellent tool for controlling hemorrhage in extremity trauma, there are many areas that do not allow proper application of a tourniquet. The video on wound packing was produced to show the fundamentals of wound packing.

    A. Identify the bleed
    B. Pack into the bleed
    C. Pack tightly to the bone if possible

A. Identify the bleed-
It is essential that the medic identify the source of the serious hemorrhage. Simply stuffing gauze into a cavity is not always effective. Often times the pressure is not applied where it is needed and the gauze only acts as a sponge. What makes packing a wound effective is that is provides focused pressure directly on the damaged vessel. By occluding the lumen of the vessel with the gauze you get hemorrhage control. If it is not completely controlled it at least slows the hemorrhage to a point where the body’s natural clotting factors can interact with the gauze to form a clot. There are three main methods to identify the location of a bleed.

    1. Visualization
    Visualization is the preferred method, but it is often unrealistic due to ballistic patterns, flooding of cavities and tissue movement. Excess blood filling the cavity can be scooped out to give a quick look, but on high pressure bleeds and blast injuries this can be very difficult.

    2. Tactile assessment
    Feel works well if you are in a relatively calm mental state and have complete awareness of your senses. It is not a reliable source when you have been carrying heavy loads, firing weapons for long periods of time or participating in any activity that has caused your hands to fatigue. It’s also unreliable if you are wearing multiple layers of gloves.

    3. Anatomy
    A basic understanding of the vascular structure of the human body goes a long way in this situation. It isn’t as good of an indicator as visualizing the bleed, but if you are pressed for time it can be a good solution. It is best when used in conjunction with the other methods. It is also helpful when determining the best angle to pack from.

B. Pack into the Bleed
Notice what the section is titled, “Pack into the bleed”. It does not say pack into the wound. Your first few sections of gauze should go directly to the source of the major hemorrhage. After that hemorrhage has been staunched, the remaining gauze should be packed tightly around it to keep it in place. Your goal is NOT to create a sponge inside the wound, but a solid mass that applies pressure where it is needed. This is a very important point. An often-asked question is, “how much blood does the Olaes bandage absorb?” The answer is this: hopefully none. The purpose of bandages is not to absorb the most blood, it is to STOP bleeding, in order to keep blood where it needs to be: in the body. You don’t put bandages on to keep your vehicle clean.

C. Pack to the bone
The major vessels of the body are not inside muscular tissue! Most vessels run near the major bones in the body. If the wound is in a location that allows you to use the bone as a rigid object to maintain pressure on the damaged vessel, use it. Start by packing into the bleeder, and then use the gauze to squeeze the vessel between it and the bone. This creates the same effect as a vascular tourniquet, or simply holding pressure with your finger.

Educating medical directors and command surgeons in the importance of wound packing is essential. The ability to pack wounds is a necessary skill in an environment with the potential for delayed evacuation times and limited manpower. The idea that you will hold direct pressure for 3-5 minutes during a fire fight is ridiculous. Packing a wound reduces the need for this and frees the medic’s hands up to engage more important things, like the enemy. When used in conjunction with hemostatic agents, it is even more effective. We will cover how these two work together in a future entry.

Phases of Tactical Medicine

The Care Under Fire Phase (Part 2)–Considerations

The Care Under Fire (CUF) phase of treatment requires a basic management plan. The plan is comprised of basic steps. Remember, it is the basics that save lives. They are as follows:

1) Regain your situational awareness.

  1. What type of threat have you encountered? An IED?
  2. What direction is the threat coming from? Will a secondary explosion/engagement occur? Is it occurring now?

  3. Are there any casualties? Am I a casualty?
  4. What do I do now? Treat the casualty? Return Fire?

2) Return Fire and/or take cover.

  1. Because this is the CUF Phase, which means you are still under fire, you are not a medic until fire superiority has been established. As the old saying goes, “fire superiority is the best medicine.”

3) Direct casualty, if applicable, to remain engaged in the fight.

  1. This may prevent the casualty from sustaining further injuries. This must be practiced in training. As Bruce Siddle has noted in Sharpening the Warrior’s Edge, practicing to play the casualty by quitting when shot during training will hinder one’s ability to do otherwise in real-world situations (i.e., do not get in the mindset that an injury precludes you from continuing to fight.

4) If patient is unable to continue to fight, direct him/her to move to cover and/or apply self-aid.

  1. This must be done in training. Get your operators out of the mindset that “doc will do medicine.” You must train them to provided self-aid, then buddy-aid, then, when applicable, expect medic-aid. The casualty is a casualty for a reason: The point of injury is dangerous, underfire, etc. Direct him to treat himself via yelling, radio, etc. Remember, however, that ears will be ringing post-explosion.

5) Prevent patient from sustaining additional wounds (SEE 3 and 4).

  1. In addition to 3 and 4, rescue ought to be considered. Practice tactical rescues in training. Train assaulters to quickly assess casualties during the tactical rescue. For example, if the casualty is talking, then airway is good. If responsive, ask where they are hit. Look for hemorrhage. Are they complaining about difficulty breathing? These are just a few examples.

6) Stop Catastrophic-Hemorrhage. (self-aid, buddy-aid, medic-aid)

  1. Use tourniquets where applicable.
  2. Hemostatic agents with pressure dressing if tactically feasible.

7) Airway management ought to be deferred until the Tactical Field Care phase.

  1. Not always possible. Be prepared to provide a surgical airway. If an airway compromise is sever enough to need attention during the CUF phase, then 99% of the time it will require a Cric. Do you have a Cric-Kit accessible? If it is in your bag, then it is not going to do the casualty much good. You need to have one in a mag-pouch, leg-bag, etc.

The above is a loose guide. Do not limit yourself to algorithmic medicine.

Situational Awareness and Selecting a Treatment Position

It is essential for a medic to constantly update his situational awareness. The tactical environment is constantly changing and threat levels fluctuate every second. While providing treatment to a casualty is important, never let it overshadow the tactical situation around you. Unless you are in a secure area you must constantly reevaluate threat levels and balance the level of care provided with the current threat.

Selecting a proper position in the CCP or positioning yourself during hasty treatment is an essential part of this task. You should position your casualties in a manner that allows you to make quick visual assessments of potential threat areas or at least provide a visual on your security element (if you have one). Placing a casualty in a corner or along a wall forces the medic into the center of the room. Not only does it limit access to the patient, it puts the medic in an exposed position and makes it difficult for them to evaluate their surroundings. It also increases the occurrence of tunnel vision. It’s easy to lose focus when you can only see one thing. If possible, position casualties in the center of a room, just remember you want to minimize their exposure to open doors and windows just as you want to minimize your own. If the room is large, consider placing them near the walls; however, leave enough space between the casualty and the wall to allow yourself workspace and room to maneuver quickly if necessary.

A dead medic doesn’t save lives. Failure to understand what is occurring around you increases your risk of injury or death. In the demo-video, take note of the manner in which the medic positions himself in the room and how he is constantly checking his threat-areas while providing aid.

Take-away Points:
1. Maintaining situational awareness is as important as treating your casualty
2. Position yourself and your casualty so as to lessen your risks
3. Performing your duties as a medic does not relieve of your tactical responsibilities

Hypothermia: Is It a Valid Concern in a Hot Enviroment?

According to information published in the latest “Lessons Learned” from Iraq it is one of the most important variables concerning the survivability of casualties. Hypothermia, as our readers know, is one of the three components of the lethal triad–acidosis and coagulopathy being the other two. Even if it is hot outside, care must be taken to ensure casualties do not loose heat. Below you will find an abstract from an article that speaks to the importance of preventing hypothermia.

The impact of hypothermia on trauma care at the 31st combat support hospital.

BACKGROUND: The primary objective of this study was to review the incidence of hypothermia, and its effect on surgical management, resource utilization, and survival at the 31st Combat Support Hospital (CSH). METHODS: This study was a retrospective analysis of all combat trauma injuries treated at the 31st CSH over a 12-month period. All trauma admissions were included. Descriptive and inferential analysis were performed using SPSS 11.0 software package (SPSS Inc., Chicago, IL). RESULTS: A cohort of 2848 patients was identified; 18% were hypothermic (temperature <36 degrees C). Hypothermia was significantly (P < .05) correlated with admission Glasgow Coma Scale (GCS), tachycardia, hypotension, lower hematocrit, and acidosis. Hypothermic patients had a significantly higher blood product and factor VIIa requirement. Hypothermia was an independent predictor of operative management of injuries, damage control laparotomy, factor VIIa use, and overall mortality (P < .05). CONCLUSION: Combat trauma patients have a high percentage of penetrating injuries with variable evacuation times. Hypothermia was a pre-hospital physiologic marker, and independent contributor to overall mortality. Prevention of hypothermia could reduce resource utilization and improve survival in the combat setting.
