Inducing Optimum Temperature Therapeutic Cooling For Higher Patient Success

It started over a year ago when Assistant Fire Chief Greg Anglin from the Melbourne Fire Department made a spontaneous visit to our business. Chief Anglin, also deputy commander in the U.S. Air Force Reserves in Langley, Virginia, is known among his colleagues as a pioneer in researching advanced technology when it comes to saving lives and protecting people. Chief Anglin is instrumental in promoting passive cooling of heart or stroke patients, which is used by first responders on the scene in direct response to a 911 call.

Whether the first responders are dispatched by a municipal fire department or a private hospital ambulance service, after resuscitating and stabilizing a cardiac arrest patient for transport, Chief Anglin focused on the procedure to waste no time and begin using conduction cooling at an optimal temperature with new five-point cooling set. Specially designed to safely remove heat from key points, cooling pads are strategically placed in the axilla (armpits), groin, chest, head/neck and as a support pad under the patient’s back, leaving the chest free and unencumbered to monitor vitals . . However, he states the caveat that conductive cooling should be at a moderate temperature that the body can tolerate (eg, not the cold temperatures provided by ice and gel packs), which could quickly worsen shock and cause a further negative response. Instead, a moderate but cool temperature of about 55 degrees F or 13 degrees C would do more to strategically conductively abstract the peak heat load and begin the process of slowing metabolic function as a precursor to therapeutic cooling in the hospital and prevent the rebound effect of hyperthermia that follows cardio-respiratory arrest. which is thought to cause reperfusion injury. It is a combination of reperfusion injury and reperfusion hyperthermia that is associated with higher mortality and negative neurologic outcomes, so avoiding reperfusion hyperthermia is positive for the patient. During reperfusion, when oxygen is reintroduced after hypoxia, a sudden burst of oxygen free radicals (called neutrophils) can cause the formation of other harmful species. These reactive oxygen species further damage cell membranes and impair cellular function, so time for treatment is critical and slowing the body’s mechanisms can be key in preventing cumulative damage.

Based on studies by Harvard University and the New England Journal of Medicine, much has been written in newspapers across the United States about the positive results of induced therapeutic hypothermia in cardiac arrest patients after return of spontaneous circulation (ROSC) for at least 24 to 48 hours. In patients fortunate enough to be transported to a hospital well equipped to effectively induce therapeutic hypothermia, lowering core temperature to 30–32 degrees C with slow, methodical post-resuscitation management demonstrates a high recovery success rate. with little or no neurological damage as a final result.

A recent study of 392 patients at the Miller School of Medicine in Miami who were given only cold saline through a large vein, according to Dr. William O’Neill, executive dean for clinical affairs, showed no benefit. The new buzzword of non-invasive cooling used initially has the highest possible success rate.

The consensus among heart surgeons, emergency room doctors, and medical professionals I’ve asked over the past few months seems to agree that simultaneous, methodical cooling is imminent for recovery…the faster the better. While many agree that mild induced hypothermia provides positive results, those who have tried the HTF Exotherm Passive Cardiac Cooling Kit find many advantages in conductive heat dissipation using the 55 degree F Cardiac Cooling Kit/Tactical Cooling Kit for simplicity and ease of use. No pumps, batteries, pipes, electricity or mechanical parts that could fail at critical moments. “A handful of these optimal temperature cooling packs strategically placed on the patient can also provide a calming effect on conscious patients when they are experiencing the anxiety and stress commonly associated with a heart attack or stroke,” Anglin says. . “This cooling kit has several positive effects.” Hospitals testing these cooling kits, some including full head cooling, are finding other applications from newborns to TBI (traumatic brain injury), migraine headaches and accelerated healing after orthopedic surgery or joint replacement.

How does this kit work? The HTF Exotherm Cardiac Cooling Kit is a simple, passive heat removal device. The heat transfer formula, packaged in anatomical packaging, consists of non-toxic, non-carcinogenic crystalline alkanes that are extremely stable. Each mixture yields a substance that melts or solidifies at a certain preset temperature and remains at that temperature for a predetermined time. Each blended formula is then encapsulated in a proprietary copolymer film containing an antimicrobial additive specific for resistance to E-Coli and Staph bacteria. These cold packs, in direct communication with a warm body, quickly begin to safely dissipate body heat. The secret of the HTF Exotherma is its ability to charge in minutes even in ice and water, so practical use when there is no electricity is an advantage. The exotic nature of the technology in these packages is FDA registered, both the formulation and the outer container, and are safe enough to be incinerated for infectious disease control in accordance with OSHA CFR 1910.

The cold temperature acts as a conductor of heat, dissipating excess body heat gained through normal metabolic activity and/or microenvironmental temperatures. Blood carried through the peripheral vessels and surrounding soft tissues gives off latent heat and cools as more and more heat is removed from the surface. Therefore, returning cold blood back through the venous return prevents the additional concomitant hyperactivity required to meet the demands of thermal regulation. Since cooler blood constantly irrigates the cardiovascular system, less metabolic energy is required, which slows down the activity of the body’s essential vitals (blood pressure, heart rate, pulmonary discharge due to increased oxygen demand) and latent heat of evaporation (sweating). When sweating is reduced, cellular metabolic activity is reduced and fewer electrolytes and valuable minerals are lost, resulting in an increased endurance factor. As there is no vasoconstriction, adequate oxygen flow is maintained for optimal muscle function, brain activity and CNS functions.

It is only recently that the therapeutic/medicinal benefits of temperature controlled stable compounds have been shown to show excellent results when used as personal body cooling or therapeutic cooling devices. Real thermal management. Recent remarkable adoption in the medical community has successfully demonstrated that the effective use of optimal temperature cooling (heat removal) in acute and chronic injuries, post-operative recovery and long-term illnesses will significantly reduce rehabilitation time and restore function to the affected area. .

Unlike frozen water or gels, alkanes at cold temperatures (45F – 60F) release energy at a constant temperature during the transition from solid to liquid; consequently, the melting and freezing points of these alkane mixtures are the same. As is well known, water absorbs energy faster due to its high heat transfer properties (heat of reaction). When water makes a phase change to ice, it absorbs energy at a rate of X and emits that same energy at an equal rate of X during the transition back from solid (ice) to liquid (water). Alkanes, on the other hand, absorb energy at a rate of X when they make a phase change from their liquid state to their solid state, but release this absorbed energy at a much lower rate when they transition back from their energized solid state to their liquid state. In this case, in the case of slow energy release, as it relates to cooling the human or animal body or for use in cryotherapy, this energy release rate can be as much as five times the rate of water for the same amount of alkanes. . Therefore, the “temperature controlled” benefactor of these alkanes for cooling experiences a much longer cooling cycle than can be experienced with ice or gels of the same volume or weight.

Johnny Hartley, Angel Flight EMT and firefighter has tested countless 55F HTF body cooling vests, including running 3 miles a day and lifting weights while wearing a firefighter rehabilitation cooling vest to reduce body heat stress when exercising in high heat indices. Hartley reports at least 2 minutes of recovery and a return to baseline of heart rate and blood pressure when running with the recovery vest. He reports that because of its simplicity and ease of use, the cardiac cooling kit takes up little space and can be sterilized for reuse with no mess, unlike ice packs. Because space in air ambulances is so large, these packs, once filled, can be rolled up and stored in a dry, insulated cooler for as long as 24-48 hours, taking up very little space. This cardiac cooling kit is currently being trialled in the UK and USA with very promising feedback.

In the United States, more than one million Americans experience a heart attack each year. If first responders could begin administering therapeutic cooling within minutes of responding to a 911 call, imagine the success rate for neurological injury prevention and recovery.
