It's rare that we can find a game changer in medicine. There is no better way to transfuse someone in the tactical environment than with their own blood. This new technology is FDA approved and will save lives when used in shock.
The act of dying from hemorrhagic shock is the culmination of a process of imbalance between supply and demand of blood flow delivery to vital life sustaining organs. The critical organs include the brain and brainstem, the heart, lungs and bowel. Life can be sustained when the kidneys are sacrificed and occasionally parts of the bowel. One can certainly live without different extremities. In order to save a dying person with life threatening hemorrhage, it is mandatory to preserve blood flow to these organs. Once past a certain poorly defined degree of blood loss, death is generally inevitable even if you are able to resuscitate the patient at that point. Usually, a late death would follow the metabolic processes of acidosis, hypothermia, coagulopathy and DIC, and infection, due to multisystem organ failure. When open chest massage was the only way resuscitation was done decades ago, immediately upon opening the chest, evacuating blood clot from the pericardium, one would immediately cross clamp the aorta to preserve critical blood flow to the vital organs.
This delicate balance between supply and demand is met by the cardiac minute flow or output which is about 5.6 liters per minute at rest in the average sized man. When the blood volume begins to drop, the body has a number of mechanisms to try to maintain the cardiac output to match the demand. Initially adrenaline and pressors are release to increase the heart rate, compress the pre-capillary sphincters and clamp down the peripheral circulation, shunting blood to the core. The heart is accelerated and maintains cardiac output in spite of a shrinking stroke volume, until it can no longer maintain. At some point the delivery of ATP to the periphery is compromised and this diversion of blood to the core is no longer feasible and the periphery dilates, pooling blood, dropping venous return and the systemic vascular resistance.
Changing this supply/demand equation has always been the goal of resuscitation. We have debated the colloid/crystalloid argument for years, evolved to the concept of permissive hypotension and the avoidance of overresuscitation with fluids., and now are moving into the era of promoting tissue conservation with drugs. An early device used and discarded was the MAST device. Although it was a level 1a and 2a recommended device for Aortic aneurysm dissections, and pelvic fractures, and although paramedics of that era 15 years ago, would attest to the effectiveness of the device, it has all but disappeared.
An alternative to this device is the MBV or Auto Transfusion Tourniquet. This device was initially developed and is FDA approved for the purpose of exsanguinating a limb for bloodless orthopedic surgery. It has been proven safe and effective for that purpose with over 300,000 uses in the world. However for the purposes of resuscitation, it serves the same purpose in reverse. The blood is moved out of the leg or legs into the core circulation, allowing for the auto transfusion of up to 1000 cc of whole perfectly matched blood, and it tourniquets the legs at the upper thighs, decreasing the demand side of the equation by 40%. This is almost equivalent to the cross clamping of the aorta at a lower level of the femoral arteries. Unlike MAST, this device is titratable by rolling it up or down the thigh. Like the MAST, it is essential that it not be abruptly removed before the intravascular volume has been restored. Keeping it on the legs for up to two hours has been well tested in the orthopedic literature and has virtually no morbidity. Even if it stays on longer with secondary neuropathies or even the loss of an extremity, it may be a fair trade to save the life.
This has been tried in terminal cases in the controlled environment of the emergency department and has been shown to be effective. It is certainly time to take it to the field to allow critical patients the extension of the Golden Hour for transport to definitive care.
